How to make a roof frame for a garage. Flat garage roof: how to cover it. Advantages and disadvantages of a pitched roof

A roof with two slopes over garages is built a little less often than a single-slope analogue. Although, according to a common misconception, one slope requires less costs, a “house” structure is often cheaper to build. Water flows freely from its inclined surfaces, so there is no point in laying multi-layer waterproofing.

There is no need to install parapets that increase the consumption of materials. The simple construction process is quite accessible to the home craftsman if he knows how to construct a gable roof for a garage in strict accordance with the technological instructions.

Houses for four-wheeled “horses” are equipped with exactly the same types of roofs as the houses of car enthusiasts themselves. There are practically no differences in the technologies for constructing pitched structures for garages and residential buildings.

The height is determined by the preferences of the owners and their plans for using the roof space. You can freely organize a workshop, a rest room or a warehouse in it, if the load-bearing capacity of the box does not cast doubt on the strength aspects.

A steep roof will require more funds for arrangement than its low counterpart. Its slopes are more substantial in size, and the elements of the rafter frame are more impressive. Therefore, even among domestic owners of brick and concrete garages There are not too many fans of tall structures if the attic is not planned to be used. They view the need to regularly clear snow from a low-pitched roof very favorably, as a good reason to visit the garage one more time and put things in order in their personal possessions.

An insulated gable roof of the garage will significantly save heat. However, without convincing climatic indicators in the construction region, it is unreasonable to improve the heating technology of a building. If necessary, place thermal insulation material between the rafter legs, protected from below with a vapor barrier film, and from above with waterproofing.

The work is carried out in accordance with the rules for constructing conventional pitched roofs; rafter systems can be made of either wood or galvanized metal.

Depending on the design data of the box being equipped, the following is used in the construction of rafter systems over garages:

  • Layered technology, according to which the upper and lower edges of each rafter leg have its own reliable support. The bottom of the layered rafters usually rests on the walls of the building. The top is placed on a strong purlin system, which in turn is supported on an internal wall or a series of support pillars inside the garage. Construction of layered rafter system begins with the construction of a frame topped with a ridge girder. It is on the frame that the tops of the rafters installed in pairs rest.
  • Hanging technology, according to which the rafters rest only on the walls of the box. The fulcrum for the upper heel of the hanging rafter is a similar part of the mirror-deployed fellow. Rafter systems of the hanging variety are constructed mainly by installing triangular trusses, the base of which most often serves as a ceiling beam, less often a screed located above. Trusses can be purchased fully prepared for installation or made independently.

Rafter systems of the layered variety are built over garages if there is a need to cover a large span. For example, in garages with two or more car boxes. These structures usually have at least one wall or a series of support posts to support the roof structure. The hanging scheme is ideal for erecting a roof over a building designed for one car. Inner walls and support pillars in small buildings are unacceptable due to the small size of the usable space.

Both types of rafter frames when covering small spans up to 5 m include a minimum of elements. The layered system consists of rafter legs installed in pairs and a purlin structure, while the hanging system consists of a number of rafter trusses. As the spans increase, it becomes more complex and is supplemented with struts, support pillars, additional purlins, headstocks, crossbars, etc.

Note that for a roof with two slopes, the construction of a rafter frame is not a prerequisite. The slopes can be formed by triangular pediments. On the sloping sides of the gables, beams are laid - beams parallel to the ridge girder and overhangs. The rafterless technique is practiced mainly in wooden construction. Brick and stone buildings It is still customary to equip gables with the help of trusses installed inside the box.

Garage roof construction technology

The simplest way to obtain information is a thorough analysis of construction methods and technologies. For those who want to know how to build a garage with a durable gable roof on their own, we offer several of the most common examples. We will consider the construction of roofs over frame walls. Their specificity lies in the fastening of the rafter system to the upper frame of the wall supports, and not to the Mauerlat of brick and concrete garages. The difference is not fundamental, but you should not forget about it, especially at the design stage, because The embedded parts for attaching the Mauerlat must be laid during the construction of the walls.

The final roofing covering for garages is chosen based on the steepness of the structure and on your own economic considerations. The material from which the walls are made is not of serious importance. In the arrangement of low-slope buildings, mainly rolled materials are used, which attract owners with their excellent water-repellent qualities.

For the roofing of higher roofs, metal tiles or economical ones are used, which please not only with the price, but also with the ability to lay the covering yourself. Ceramic tiles and natural stone above domestic garages are extremely rare, and then only if uniform landscape requirements are imposed on the site.

Layered garage roof options

An example of a gable roof over a “single” garage is quite accessible to an inexperienced performer. The roof is cold, but if desired, this aspect can be thought through and finalized yourself. The width of the board from which the rafters of the insulated roof will be made should be selected so that the thickness of the insulation is 3-5 cm less. This difference is necessary for the formation ventilation flows, removing evaporation and condensation from the insulation.

If purchasing boards of the required size does not work out, a sheathing is nailed on top of the rafters - a block that increases the missing width.


The simplest rafter structure

Step-by-step instructions for craftsmen who decide to build a cold gable garage roof with their own hands:

  • We mark along the top trim of the long walls of the garage. We note the installation step of the rafters, which according to the project is 40 - 60 cm. In short, we simply divide the wall into equal sections, the length of which is not less than 40 cm, but not more than 60 cm. We mark from the corner of the box, do not forget that the outer pairs of rafter legs must be installed flush with the end walls.
  • We mount ceiling beams. According to the markings, we install the board on both walls. She must lie on her edge strictly horizontally. We check the horizontality with a level gauge and fix it with a pair of nails or corners. Ceiling beams, along with the main work, play the role of tightening, compensating for the expansion. If you need to inexpensively insulate a building, then it is better to place the thermal insulation between the ceiling beams, providing the inside with a vapor barrier film and additional sheathing.
  • We lay pieces of plywood or similar material along the installed ceiling beams to provide access to the rafter frame construction site.
  • Mark the middle of both end walls, put a mark on top harness. We temporarily nail the rail to the ends so that one of its faces coincides with the conditional central axis. An auxiliary rail is needed for precise definition ridge position and for making rafter templates.
  • We apply the board from the end to the installation site of the outer rafter leg. We mark the cut lines as they happen. This is a template, we use it to make the rest of the rafters with equal sizes and cuts.
  • Focusing on the auxiliary slats, between which it is advisable to stretch the cord, we install supports under the ridge girder. When constructing long-span structures, we install supports every 120 cm. Having checked the verticality, we fix the racks with metal corners with a reinforcing jumper.
  • We lay the ridge girder edgewise on the support posts, check the horizontality and nail it.
  • We nail a block to the base of the supports located in the middle, parallel to the ridge girder. It will serve as a bench, the installation of which would put too much strain on the frame building.
  • We mount a strut, the top of which rests against the purlin, the bottom against the block at the base of the support. The angle of inclination of the braced part is about 45º. If several struts are to be installed, they are directed in opposite directions.
  • We move the prepared rafters to the roof, put them in place, fasten them with nails at the top to the purlin, at the bottom to the trim and to the nearby ceiling beam. We start with the outer pairs, between which we should stretch the lace. Based on the readings of the laces, we install ordinary rafters.
  • We dismantle the auxiliary block. We replace it with two posts nailed to the rafters at the top and to the trim at the bottom.
  • We equip every second pair of rafters with a tie.
  • To design the gable overhangs, we attach shortened cantilever beams with corners to the outer pairs of rafter legs, then we sheathe the perimeter with a wind board.

To make rafters, struts and beams we use 50×150mm, 50×200mm or 50×250mm boards. It should be taken into account that the cross-section of the material for the ridge run must be larger than the cross-section of the ordinary elements of the rafter system. The puffs can be made from 25x100mm boards.


For the finished rafter system, you need to make a sheathing: solid, if you plan to lay rolled material, sparse, if it will be made or profiled steel sheet.

In the construction of layered rafter systems for small garages, the same technological principles are used. Regardless of the steepness of the slopes independent master you will have to complete all the stages of work described above.

Lay strips on top of the finished rafter system roll waterproofing, the installation of which is carried out from the overhang to the ridge girder, then the sheathing and roofing.

Long-span pitched roof

An example of the construction of a roof over a long-span box confirms the unshakability of technological principles. The peculiarity of the structure is that the facility being developed is conditionally divided into sectors.

Except load-bearing walls There are two rows of support posts on which the side girders are laid. The purlin structure does not rest on the beams or floor beams, but on additional racks. The sectors of the box do not exceed the limit of 5 m, so they are not reinforced with rafter legs - struts.

Hanging roof schemes for garage

Hanging rafter systems are rightfully leading the way in the construction of small-sized garages. Owners and builders are not afraid of the complexity of repairing and replacing damaged parts of a hanging rafter system. It is much more convenient and safer to connect the rafter legs into trusses and then lift them onto the roof than to install each layered element separately at a height.

Elementary method of construction

Before erecting a roof using the hanging method, you should make an accurate calculation or stock up finished project with the exact dimensions of the gables.

Hanging rafter system for garage roof We will construct it as follows:

  • We mark the future position of the rafter legs according to the project instructions.
  • In accordance with the dimensions indicated in the project, we make trusses and file the lower grooves to support them on the frame.
  • We first install the outer trusses adjacent to the gables and connect them together with a cord.
  • We install intermediate trusses, not forgetting to check the cord readings. The upper edges of the rafters should form a flat imaginary plane.
  • We install diagonal wind ties from inside the building. They will ensure the rigidity of the rafter frame.
  • We cover the gables with OSB-3 slabs.
  • We attach shortened beams to the ends of the outer trusses to form gable overhangs.
  • We install a wind board around the perimeter.
  • On top of the finished one truss structure We attach the lathing, the type of which corresponds to the type of finishing coating and the requirements of the material manufacturer.

In the example, the sheathing is arranged for soft looking coverings from OSB boards. A continuous roofing deck with similar characteristics can be made from boards. Those who want to find out how to properly sheath a gable roof on a garage should know that the slabs are laid staggered, and the boards are laid parallel to the overhangs or at an angle of 35º-45º to them. Between the elements of the sheathing, gaps of at least 3 mm should be left, necessary for thermal expansion of the materials.


A significant advantage of hanging structures is that the ties also work as ceiling beams. In the disassembled version, the screed is too high, and interior lining is carried out directly on it. Attic in similar design solution excluded. But thanks to the inflated screed, the ceiling and interior space increase, which can be seen in detail in the photo of the stages of installing a gable roof of a garage:


If hanging rafter triangles are to cover a span of more than 9 m, the tie is spliced ​​from two boards or beams. A suspension headstock is installed at the top of the triangle to prevent sagging of the tightening. It is connected by struts to the rafter legs. At the bottom of the suspension there is a device for tightening the tension in case of sagging.

Suspended structures for large spans

Hanging rafter systems are suitable for spanning spans up to 14 m. In private households, garages of similar dimensions are rare. However, large-sized buildings are often equipped with hanging roof trusses, as in the presented example of a two-story garage.

The walls of the two-story garage are made of timber, the pediments and internal partition. Timber gables make it possible to refuse rafter diagram through installation lightly. However, the roof frame in the example is made traditionally: using hanging rafter triangles.

Rafter trusses are installed in the usual way: with the lower notches resting on the walls, with the tops facing each other. The junction of the tops is reinforced with wooden grooves. The ceiling of a cold roof is lined with plasterboard from the inside of the rafter system. Outside, a continuous waterproofing carpet is laid on the rafters.

The material is laid in strips with slight sagging in case of traditional wood movements due to moisture fluctuations with temperature. The waterproofing strips are laid in the direction from the overhang to the ridge; they are attached to the rafters first with a stapler, then with sheathing slats. A sparse sheathing is installed under the metal tiles and corrugated sheets at a pitch specified by the manufacturer. Under metal coatings It is unacceptable to install bitumen waterproofing with a polymer shell.


In the case of constructing an insulated roof over two-story garage For the specified project, it is advisable to distribute the stages of work in a different way. The first step is to lay the waterproofing, install the sheathing and secure the covering to it.

On large-area objects, it is more convenient and reasonable to install thermal insulation slabs or mats when outer part The roofing pie is completely ready. This eliminates the risk of the thermal insulation getting wet, which creates the threat of gradual destruction of the wooden elements of the rafter frame.

Video selection to help self-builders

The topic of the proposed video: construction of a garage and a gable roof for those who want to build with their own hands.

The basic options we have presented for constructing roofs with two slopes over garages demonstrate the basic principles of the structure. The proposed schemes are quite suitable for the construction of a free-standing box with a gable roof. Standard designs can be modified to suit individual requirements.

A garage is a room, of course, not intended for housing, but it cannot perform all its functions if the roof constantly leaks. Car owners especially often encounter this phenomenon in the spring, when the snow accumulated on the roof begins to melt. But a well-made roof will not leak or cause problems, and your car home will always be dry and cozy. What is the best way to cover the garage roof to avoid all the troubles?

The purpose of any garage is protection from the external influences of a vehicle. Rain, snow, wind can quickly ruin appearance cars, and for a motorcycle standing on the street, such effects are simply disastrous. Due to excess moisture, corrosion processes on metal products begin to occur quite quickly, destroying the metal. That is why the garage must be of high quality and have no leaks.

The roof on the garage can be single-pitch or gable. These are the most common options. In the first case, it is easiest to make a roof - it consists of one slope, resting on the walls of the building with different heights. The angle of inclination can be different (up to 60 degrees) - usually this indicator depends on the climate in the region, the wind rose, and the selected roofing covering.

On a note! A roof with one slope is usually constructed if there is no need to create an attic.

The roofing material is laid on wooden rafters. The height of the difference is calculated using the formula H = D x tan a, where D is the width of the garage. The last indicator is selected according to the Bradis table. Wood for rafters must be treated with antiseptic compounds that will protect the material from the effects of biological organisms, and it is also recommended to coat it with compounds that reduce the likelihood of fire (fire retardants). Go to category pitched roof This also includes the roof, which is often found on garages built of concrete.

A gable roof is built if the garage is planned to be equipped with an attic. Typically, such a roof has the shape of a triangle. The frame consists of rafter legs connected at a certain angle, supported by the walls and at the top point of their connection. The height of the roof ridge H and the length of the rafters C can be determined using the formulas N = 0.5 x N (Z:2) And C = 0.5 x N/sin (Z:2), where Z is the slope value. For an equilateral roof, the appropriate option is to use the Pythagorean theorem.

Less often, but still, a multi-slope roof is installed. However, it is already much more difficult to implement, so rarely does anyone undertake to build it with their own hands.

Advice! To create a roof on a garage with your own hands, beginners are advised to opt for a simple pitched roof.

Table. What else do you need to consider?

ParameterDescription

To select the type of roof and materials for it, it is worth taking into account the type of foundation and its strength, the strength of load-bearing walls and ceilings. After taking into account the main indicators, the roofing material is selected in accordance with them.

It is important to take into account the wind load on the building, the location of the garage, and the frequency of snowfalls and rains.

If the garage is located in a cooperative, then it is recommended to select roofing material so that it is in harmony with the rest of the buildings.

To create a roof and cover it, you may need various tools. It’s worth making a list of what you need and purchasing or renting them before starting work.

Comparison of materials

You can use any roofing materials for the garage roof. Of course, most owners want to save on construction by choosing a material that is suitable in both quality and cost. Let's look at the main types of coatings used for roofing.

Ceramic tiles

This is one of the most beautiful and popular types of roofing material. It is made of clay and therefore has such advantages as resistance to rust, exposure to sunlight, low temperatures and attack by microorganisms. The service life of the coating is long and amounts to about 100 years. Disadvantages include the significant weight of the material, difficulty in transportation due to fragility, and fairly high cost.

Installation of such a roof is easy, but if the roof slope angle is more than 12 degrees, you should not use tiles. It is also not suitable for finishing a concrete garage.

Prices for different types of tiles

Roof tiles

Ondulin

This is peculiar soft version slate, otherwise called euroslate. Has several color variations, which allows you to choose it for any building style. The service life of the coating is 20 years (warranty period), the material protects the roof well from leaks, is not dangerous from an environmental point of view, is easy to install and is lightweight. The advantages include its low price. The disadvantages include the flammability of the coating, but it will never catch fire on its own. It also fades quickly in the sun and loses its color brightness.

Prices for various types of ondulin

One of the oldest roofing options. It is a corrugated sheet made from an asbestos-cement mixture. The material is durable, easy to repair, does not rust, is cheap, and does not burn. However, it is quite fragile, and if the roof is not properly sealed, leaks can form.

On a note! Slate is one of the cheapest coating options, which is why it is often used to finish the roof of a budget garage.

Prices for different types of slate

Metal corrugated sheeting

A roofing option that replaced slate. It is made of galvanized thin steel sheet, has waves or trapezoidal corrugations, due to which it acquires additional strength.

The material is easy to install, has a lot of color variations, and lasts a long time if installed correctly. Due to the polymer protective coating, it is not afraid of rust and does not fade. The main disadvantage of the material is that if the polymer layer is damaged, the sheet will quickly rust. Moreover, the coating can be damaged just by walking on it in rough shoes. It costs more than regular slate.

An option that is quite often used for finishing pitched roofs and flat roofs. It is a rolled material consisting of thick cardboard impregnated with bitumen and covered with a protective coating. It is very cheap, durable, well insulates the roof from water, and easy to use. However, the material easily catches fire, breaks, and looks, to put it mildly, ugly. Can be used as a waterproofing layer in roof construction.

Polycarbonate

Yes, you can also use this material to make a garage roof or create a small carport. Polycarbonate can be structured or monolithic. The latter resembles glass and is completely transparent. Suitable for creating a flat roof option.

The first version of polycarbonate is known as cellular or cellular. Very light, quite durable and flexible.

Roofing process

Decorating a garage roof can consist of several stages, depending on what kind of roof is needed. For example, it can be built from scratch and for this you will have to build a rafter system, lay waterproofing, and install a covering. If you don’t need to make an insulating layer, the work will be significantly simplified. Also, the roof may already be ready (for example, concrete), but needs additional finishing.

Important! When choosing a material, it is worth considering the angle of inclination of the roof. For roofing felt, the optimal option is an angle of up to 5 degrees, for slate - no more than 25-35, corrugated sheeting is laid on a roof with a slope of up to 8 degrees, and metal tiles can be used on a slope of up to 30 degrees.

All work should be carried out only in sunny weather. It is best to check the forecast for at least a week and choose warm days.

Concrete roof finishing

Even if the garage already has a concrete roof, it must undergo special preparation before the new roofing material is installed. In general, the process begins from this stage and ends with laying a new coating.

Preparation

Step 1. The old coating from the concrete slab, if any, will have to be completely removed. This is done using improvised means - for example, a shovel, chisel, etc.

Step 2. The concrete surface is inspected - its condition must be good before further finishing. It is tapped with a hammer - everything that peels off during the process must be removed.

Step 3. All small cracks are sealed with cement laitance (or liquid glass), which is applied with a regular wide brush. Wide cracks can be repaired polyurethane foam, the excess of which is then cut off with a sharp knife.

Step 4. Uneven base is leveled cement mortar. It is applied to the surface and leveled using a rule. Next, the cement layer is dried.

Step 5. After drying, the cemented surface is treated with deeply penetrating primer. It is applied with a roller or sprayer in an even layer.

Step 6. When the primer layer dries, the surface is covered with bitumen mastic.

Roofing work on a concrete roof

Step 1. Work on laying roofing felt on the roof begins with lifting rolls of material onto the roof surface. Next, one of the rolls is laid in the corner of the roof and using gas burner bitumen mastic applied to the base heats up.

Step 2. A roll of roofing felt without sprinkling is carefully unrolled using a metal hook as the mastic heats up. The burner flame is also directed to the lower part of the rolled material. In this way, the entire roof is covered, individual strips of material are laid overlapping each other.

Step 3. The top layer of material is laid, which already has powder on the surface. To begin with, the required dimensions of the segments are measured. For ease of use, they are rolled into rolls.

Step 4. The top layer of material should be laid on top of the bottom one so that the seams overlap each other, that is, offset. Laying begins from the bottom point of the roof slope.

Step 5. And again the gas burner comes into play. The previously laid lower layer of material is heated.

Step 6. After the bottom layer is well heated, heating and rolling out of the roll with sprinkles begins. Rolling is also done using a hook.

The same metal hook is used

Step 7 The material laid in this way is sprayed with water to speed up the cooling process. Also, a layer of water will prevent crumbs on the coating surface from sticking to your hands and tools.

Step 8 The material is pressed to the roof surface using patting movements using a wooden board wrapped in fabric.

Step 9 The entire roof is closed in the same way. The individual strips of coating are laid overlapping.

Step 10 The sides of the roof are also covered with roofing felt.

The process of finishing a garage roof with corrugated sheets

Quite often, corrugated sheeting is used as a roofing covering when constructing a garage. This one is durable and durable material will serve faithfully if installed correctly.

Preparation

Step 1. The roof is being prepared - if necessary, a waterproofing layer is laid. Next, the installation of supports for the material begins - 50x50 mm bars are laid on the base, and 40x15 mm boards are placed across them.

Step 2. The bars are leveled strictly, and the crossbar boards are also leveled.

Step 3. The longitudinal bars are attached to the base of the roof using frame bolts.

Step 4. The transverse boards are fixed with self-tapping screws to the bars - two pieces at the edges, and one at a time in the middle of the boards.

Step 5. Planks are nailed along the perimeter of a kind of sheathing. Their upper part should be flush with the crossbar boards. You can start laying corrugated board.

Installation of corrugated sheets

Step 1. Sheets of corrugated sheets are lifted onto the roof, laid on the sheathing and leveled. Separate sheets are laid overlapping in 2 waves. To install the roof, it is better to use sheets of such a size that you can cover the roof slope from edge to edge at once.

Step 2. Where the garage pipe exits, it is necessary to trim the material so that a hole is formed for the chimney. The easiest way is to cut a hole in the whole sheet, and then put the sheet on the pipe.

Step 3. The corrugated sheets will be screwed on with self-tapping screws. For convenience, you can apply markings along a string stretched evenly from one edge of the roof to the other. The markings are applied with a marker. The markings should be located directly along the crossbar boards.

Step 4. Special roofing screws with a rubber washer-gasket are screwed in. Along the perimeter of the sheets, their pitch is 40-50 cm, and along the rest of the sheet, according to the markings, they are screwed through one corrugation.

Step 5. Side part The roof can be finished with roofing felt reinforced with bitumen mastic, or covered with metal shields of the required height.

Step 6. The panels are fixed using roofing screws, and the joints between them and the roof are covered with bitumen mastic.

Step 7 Fabric strips are glued onto the first bitumen layer, which are then coated with bitumen again.

Step 8 The joint between the pipe and the corrugated sheet is sealed with waterproofing material or sealant.

What material should I use for the garage roof? Here the owner himself will have to decide in accordance with his wishes and budget. It is also important to consider the features of each coating. But of the two main materials listed above, it is better to use corrugated sheeting - it will be more reliable and durable for the roof than roofing felt.

The types of roofs for a garage are quite different, here the area of ​​the building comes first. The larger it is, the more stingrays there will be.
Garage roofs are also divided according to the material they are made of, so they also have different weight. And the heavier the roof, the more powerful the frame must be made.
Today we will look at the construction of a garage roof. You will have the opportunity to watch a video of a garage roof with your own hands and from the photo you will be able to see their varieties.

Types of roofs and roofing materials

First you need to consider what they are and then choose required material and determine what to make the garage roof from. The roof of a garage can be done independently; you don’t need to be a great specialist, but of course you need to have an idea.
Moreover, you can only make simple options. First you will need to properly study its design.
For these purposes, you can consider the two most popular types of roofs. Each has its own design features.

Attention: First of all, before purchasing material, you need to make a design for the garage roof. Then you can correctly calculate the amount of material.

Shed roof

A flat garage roof is suitable for a small room. This type of roof is the easiest to implement. Most often seen frame garage with a flat roof.
It is quite easy to assemble; installation instructions are provided upon sale. A wooden garage roof is also made in buildings where there is no big square land and there is no way to increase it.

So:

  • The support for it is the walls of the building, erected to different heights, and the simplest rafter system is used.
  • The level of slope of a given roof may vary. It should be selected based on climatic conditions (including the presence of constantly blowing winds) and the selected material for roofing.
  • The angle of inclination of a pitched roof can be made from 0 to 60 degrees. It is not recommended to make the roof slope greater than this value. The properties of the material chosen to cover the roof will determine the amount of its slope (slope).

Attention: The larger the roof plane, the greater the slope should be. This will reduce the load on the frame and precipitation will be better removed.

  • The basis for the construction of any roof is the rafters. The rafter system is made from well-dried spruce or pine boards and beams, which are pre-impregnated with an antiseptic.
    It is this that serves to protect wooden structures from fire, dampness, and insect pests. For the construction of a shed roof, an inclined rafter system is more suitable than others.

Gable roof

A one-car garage with a gable roof can be seen quite often. We have instructions on how to install it on our website.

So:

  • In addition to aesthetic advantages, a gable garage roof also has purely practical ones. It makes it possible to arrange a convenient attic space. The simplest gable roof has the shape of an isosceles triangle.
  • There is nothing complicated in its design if you have the desire and necessary materials and tools. The rafter system and roofing are the components of any roof.
    The rafter legs are installed in rows in pairs and connected by the upper part in the area of ​​the roof ridge, thereby forming its frame. The lower part of the rafters rests on the mauerlat (horizontal beam), which in turn is attached with anchors to the walls of the building.
  • The width of the roof and its height to the ridge are necessary to calculate the amount of materials required. To calculate the height of the ridge and the length of the rafter leg, measurements of the width of the walls of the building and the angle of inclination of the roof are needed.
  • Installation of the rafter system is done in stages, starting with strengthening the Mauerlat and ending with the installation of sheathing for further covering of the roof with the selected material. If the Mauerlat is attached to the walls of a building made of concrete or brick, then waterproofing must be done between them (see). A roofing material lining can serve as it.

Materials for making a roof

Garage roofs can be made from different materials. They have quite different prices and it all depends on the state of your wallet.
A garage with a tile roof will be much more expensive than a slate roof. But laying metal tiles will take less time. But there are other materials that are used quite often.

Ruberoid

This widely known material is considered the easiest to use and inexpensive. One roll of roofing felt is enough to cover 10 square meters. meters of roof.

So:

  • Laying roofing felt (see) on concrete base This is done only after it has been completely cleaned of old coating and dirt. A layer of hot bitumen mastic is applied to the concrete, and immediately, without waiting for it to cool, a layer of roofing felt is laid. To ensure that the material adheres tightly to the surface, it is leveled with a special roller.
  • Fused roofing felt can be laid without clearing the surface of the old coating. Using a gas burner, a roll of roofing material is heated until the adhesive layer begins to melt, and pressed tightly to the surface, rolled out. The canvas is also leveled using a roller.
  • Ruberoid coating requires periodic inspection to timely identify damage and carry out the necessary repairs.

Galvanized iron for roofing

A galvanized iron roof has a long service life and is relatively cheap, but it has some disadvantages.


So:
  • Sheets of iron are laid overlapping from bottom to top, starting from the bottom corner of the roof. Attached with self-tapping screws with steel spacers.
  • Installation of sheets with a locking system allows you to avoid damage to the material, since it is carried out without making through holes, which prevents the penetration of moisture.
  • To extend the life of your roof, you should paint it. Acrylic primer-enamel for galvanized iron will well protect the zinc layer from the negative effects of weather conditions.

Bituminous shingles

Soft tiles are a new generation of roofing material. Made from cellulose coated with bitumen.
Essentially, these are multi-colored pieces of roofing felt of different shapes, treated with polymers for strength. The roof from it turns out to be similar to a classic tiled one, but in a modern design.

So:

  • The composition of this modern material: fiberglass, modified bitumen and stone pavement. It is recommended to lay it at a temperature of at least 5 degrees, otherwise it becomes fragile.
  • Installation of tile strips begins from the bottom in the center, and then proceeds along the eaves in vertical rows. Each row is shifted relative to the previous one. This is done to form a beautiful pattern.
  • Sheets soft tiles fastened with galvanized nails. The edges of the strips (shingles) are glued with bitumen mastic, which improves waterproofing.
  • To obtain a roof of uniform color, it is recommended to mix tiles from different packages.

Slate

Traditional asbestos-cement slate is most often used for roofing.

The installation and installation of slate roofing is carried out similarly to the installation of a corrugated roof. The slate is attached to the prepared surface using slate nails or special screws.

Attention: You must first drill holes in the slate sheets. Internal corners Each sheet is cut diagonally to ensure a tight fit of the slate.

Recently, modern roofing coverings, for example, corrugated sheeting (see). It is superior to slate in both ease of installation and service life.

Ondulin

Another popular modern roofing material.

So:

  • Made from cellulose and impregnated with bitumen, ondulin is much more environmentally friendly than materials that contain asbestos. This material provides good waterproofing and prevents noise penetration.
  • During installation, you need to pay attention to the gaps that may form at the junction of the slopes. They must be sealed with a profile seal.

Attention: It is not recommended to walk on an ondulin roof; it does not support heavy weight. To avoid rapid fading of the material, when purchasing it, you should choose a reliable manufacturer.

Polycarbonate

Garage roofs can be covered with 2 types of polycarbonate: monolithic and cellular:

  • Monolithic sheets resemble glass in appearance and properties, but they are stronger and lighter. Well suited for working on flat surfaces.

Attention: Due to the cost being significantly higher than other materials, monolithic polycarbonate is not in demand.

  • Cellular polycarbonate, on the contrary, has gained great popularity. Its advantages in flexibility and lightness allow it to be used in the construction of fantasy structures. It stands significantly lower than its brother, and resists fire and chemically active environments well.
  • The high strength of cellular (or cellular) polycarbonate has a positive effect on its service life.

The garage roof can be covered with any of the listed materials, you just need to choose the one that is most suitable in your case.

A reliable garage roof is an important condition safety of the building. Roofing work in a garage is basically carried out in the same way as on other buildings, but there are some nuances.

Types of garage roofs

Based on their design features, several types of roofs can be distinguished. Based on the presence of roof slopes, there are:

  • pitched;
  • flat.

Flat roof requires the construction of a continuous elastic coating made of polymer-bitumen materials that are resistant to temperature changes. The supporting parts for such a structure are the walls of the building. Screeds or slabs can be used as a base. In some cases, they do it on a flat roof hanging garden. In this case, the structure will be operational.

A pitched roof is formed by bases, the angle of inclination of which can be from 10 to 60°. The structures focus on the rafter mechanism. The following types of roofs can be built for a garage:

  1. With one ramp. The structure has an emphasis on the walls of the building, and therefore one of the walls must be higher than the others in order to be able to create a slope. The height difference is calculated by the formula: H = tg α x s, where s is the width of the building, tg α is the tangent of the angle of inclination, the value of which can be calculated on a calculator or taken from Bradis tables. The size of the roof slope depends on the climate of the region: the amount of snow and the strength of the constant wind.

    A pitched roof is formed by walls of different heights

  2. With two slopes. This option is most often used when constructing garages, as it allows you to increase usable area building due to the attic space. A roof of this type can be made with or without an overlap, but it must rest on a mauerlat - a horizontal frame made of bars that combines the rafter mechanism into a solid structure.

    The gable roof increases the usable space of the garage due to the attic space

  3. Hip roof. It is used quite rarely for garages, but in some cases it is used to maintain a uniform style of territory development. In this case, the rafter mechanism will not have a ridge run, since the roof frame is formed by four identical slopes.

    The hip roof consists of four identical slopes

  4. Attic. This type of construction allows you to build over a garage building extra room, which can be used by the owner for his own needs. For example, you can create a workshop, storage room, office or guest room. It differs from the attic space in the height of the ceiling: at least 1.5 m. This roof project is considered expensive, since it requires steam, hydro and thermal insulation. You also need to install double glazing non-standard shape. The rafter pair will have a sharp bend, which may result in a decrease in the strength of the building.

    The minimum ceiling rise in a room under an attic roof is 1.5 m

Materials and tools for manufacturing

Proper construction of a roof with a single slope implies maintaining the slope required for the unhindered drainage of melt water after rain or snowfall. The height of the supporting parts should be different. The slope should be selected taking into account the following factors:

  1. Climate of the region in which the events are held construction works. Flat roofs with a slope of 5–7° are not advisable in regions with a lot of snow. However, they are suitable for places where there is strong wind. Roofs with a slope of 20–25° should not be constructed over detached garages in regions with moderate winds. Such structures can only be erected over attached buildings.
  2. Type of coating material:
    • when making roofs with a slope of 15° or less, it is necessary to use materials in rolls - polymer, polymer-bitumen or bitumen;
    • if the slope is up to 10°, then the roof should be installed in 2 layers;
    • at an angle of inclination of 17–20°, metal sheets fastened with a seam, flat or wavy slate are used;
    • for roofs with a slope of 25° or more, it is better to choose profiled sheets or metal tiles.
  3. Site design. Architectural features require the use of roofing of the same color and shape throughout the entire territory.

When calculating the area of ​​the slope, it is necessary to take into account the installation of overhangs that protect the structure from rain.

Overhangs are extensions of the roof structure that protect the building from rain and snow.

It is important to consider the following nuances:

  1. There should be overhangs of 55–60 cm above the log house.
  2. The overhang over the iron-clad frame structure should be at least 15–20 cm.
  3. The overhang over a building made of concrete or brick should be 35–40 cm.

In some cases, the size of the overhangs is made larger to form a canopy from the entrance or along the wall. The canopy will need to be supported on support posts made on a separate or common base with the garage.

Garage roof covering material

The roof of a garage can be covered with different materials. You need to choose based on operating conditions and financial capabilities. For example, a building with a tile roof will cost much more than a building covered with slate. At the same time, laying metal tiles takes a lot of time. The most commonly used materials are:

  1. Ruberoid. This is a material based on thick or lightweight cardboard impregnated with bitumen. It is coated with refractory bitumen, after which minerals are added to it. Tensile load - 26–28 kg. One roll is enough to cover approximately 10 m2 of roof. Roofing material can withstand heating up to 80° for two hours. The material can be used with a slope slope of at least 5°. The rolled sheets are joined with an adhesive mixture or mastic in several layers or fused using a gas torch. Ruberoid is recommended to be used if a garage with a roof is being made complex shape. Main advantages of the material:
  2. Bituminous shingles. This is an artificial soft material for roofing, which is based on fiberglass impregnated with rubber bitumen with a powder of basalt or slate. Service period - up to 50 years. The decorative effect of the coating is achieved through a wide range of colors and cutting shapes. Bituminous shingles have all the advantages of roofing felt, but have a more aesthetic appearance. An additional advantage is the ability to replace individual fragments when performing repairs. The material can be installed on a roof with a minimum slope of 2°.

    A roof made of bitumen shingles has a much more aesthetic appearance compared to roofing felt.

  3. Ondulin. This is a molded mass based on cellulose, bitumen, various pigments and fillers. After drying, sheets with waves become resistant to chemical attack. The advantages include low weight and low cost. The period of possible operation is up to 15 years. On sale can be found in the material different colors. To fix the sheets, special fasteners should be used.

    Ondulin is well suited for garage roofs because it is a light and beautiful material

  4. Slate. It consists of asbestos cement sheets with a surface in the form of waves. Despite not the most aesthetic appearance and hygroscopicity, it has quite a lot of advantages:
  5. Iron sheets. The material has a polymer coating and is strong and durable. The sheets are folded together into a lock, which requires experience in carrying out this work and special tools. The permissible slope is 19–30°. On metal roofing it is advisable to apply additional protective covering, which can be arranged using acrylic paint.
  6. Profiled sheeting. These are wave-shaped metal sheets that are laid with an overlap in one wave on each side and are attached to the sheathing with roofing screws, which significantly simplifies the installation process. The recommended tilt angle is from 8°.

    You can cover your garage roof with a profiled sheet in just one day.

  7. Metal tiles. It is one of the most popular roofing materials. The properties of metal tiles are similar to corrugated sheets, but they look much more attractive. The coating consists of profiled iron sheets about 0.5 mm thick with a smooth or rough surface, protected by a layer of polymer coating. Average service life is 30 years. The minimum slope is 14°.

    The coating from a distance resembles natural tiles, but is much cheaper

Garage roof tool

In order for the work to be carried out efficiently, you need to prepare the following tools:

  • hammer;
  • a wooden mallet;
  • jack for lifting material onto the roof;
  • roulette;
  • level for taking measurements;
  • spatula if you plan to plaster and paint the garage;
  • metal scissors if you plan to use corrugated sheets;
  • saw;
  • axe.

Some metal roofing materials will require hole preparation. In this case, you should add a countersink and a countersink to the list.

DIY garage roof installation

The roof for a garage building consists of the following elements:

  1. Rafter mechanism. It is used as a base on which all parts are fixed. The structure will take on the general loads of the roof.

    The rafter frame sets the shape of the roof and is its load-bearing part.

  2. Lathing. Serves as a support for fastening the roofing.

    The sheathing pitch depends on the roofing material used

  3. Materials for hydro-, steam- and thermal insulation. Required to retain heat and protect the building from moisture.

    In order for the roof to retain heat and protect the garage from moisture, it is necessary to lay insulating materials in a certain sequence

  4. Finish coating.

    Laying the finishing coating is the final stage of roof construction

  5. Additional parts to strengthen the rafter mechanism.

If you plan to build a garage with a pitched roof, then you need to place a mauerlat or logs on the upper end parts. The elements will be used as support for the rafter mechanism. They are fixed to the walls using wire through anchor bolts. The fasteners must be driven into the wall or embedded in the masonry.

The main parts of the rafter mechanism gable roof are the rafter legs. They can be:

  • suspended (supported by the outer parts);
  • layered (have intermediate parts for support).

If the span that is formed supporting walls, has a length of less than 5 m, then only horizontal elements can be installed on the rafter frame. They are called crossbars. In the places where the mauerlat and rafter legs are attached, you need to prepare holes for fastening. The supports are installed in these holes and securely fixed with nails or anchor bolts.

Mauerlat installation

Laying the roof for the garage should begin with the installation of the Mauerlat. For this, a 15x10 cm beam is used. If the walls of the garage are made of timber, then the upper crown can be used as a Mauerlat.

  1. For walls made of brick or concrete blocks, a reinforcing belt is made. Steel pins are mounted into it, onto which the Mauerlat will then be put on. The design of the armored belt is required not only to distribute the loads from the roof, but also to horizontally align the end surfaces of the walls. Without this element, the slope may be different in different parts of the roof.

    Before pouring concrete, metal threaded rods are welded to the reinforcement frame so that their protruding part is several centimeters longer than the mauerlat beam

  2. Concrete is poured into the formwork, its surface is finally leveled, and then the structure is covered with a layer of roofing material and left until completely dry (at least 7 days).

    After leveling the concrete layer, the studs should extend out of it to a height exceeding the thickness of the Mauerlat by 3–5 cm

  3. The mauerlat beams are mounted. At the locations of the studs, holes of the appropriate diameter are drilled, and the beams are put on the studs. The nuts are screwed on top.

    After the Mauerlat beam is laid on the armored belt, it is secured using nuts screwed onto the ends of the studs

  4. The rafters are fixed to the mauerlat. The simplest method is two nails with a length of 150 mm, located crosswise, or iron staples. For better fastening, you can use metal plates.

    Using metal plates, you can make a sliding mount, which will allow the elements to move within small limits during frame shrinkage and seasonal deformations of the building

Marking rafters and making sheathing

At this stage you will need to mark the rafters:


Installation of rafters for a pitched roof is not difficult. When installing a rafter mechanism, you should be guided by the following principles:


As the base of the garage roof, a lathing made of slats or iron purlins should be used under the covering material. The sheathing is selected as follows:


The sheathing must be done from bottom to top.

Each batten should be attached to one nail to the rafter leg.

Insulation and waterproofing of garage roof

External insulation of a garage roof should be done in the following sequence:


Internal roof insulation is performed as follows:

  1. First of all, a waterproofing layer is performed. The joints are sealed with tape.

    It is better to lay the waterproofing film with a slight sag to avoid excessive stress due to temperature deformations

  2. If you plan to use polystyrene foam, then a sheathing must be made under it. Next, the sheets are attached using self-tapping screws. During the process, you need to glue the joints with an adhesive mixture.
  3. If mineral wool is used, it is placed in the gaps between the rafters.

    Mineral wool slabs should fit into the gaps between the joists and stay there without additional fastening

  4. The insulation material is covered with a vapor barrier film. The joints are taped with construction tape.

    The vapor barrier film protects the insulation from warm, moist air escaping from the lower rooms

Care should be taken to insulation material did not come into contact with the waterproofing film. There should be a gap between them. To do this, a counter lath made of 30x40 or 50x50 mm bars is stuffed on top of the film. If a superdiffusion membrane is used for waterproofing, the device ventilation gap not required.

Insulation of the roof inside can be done using penoizol.

Penoizol is applied to the roof by spraying

The foam material should be applied by spraying. It will penetrate into all gaps, expand as it dries and be distributed throughout the entire base. As a result, there will be no cracks into which moisture or cold could penetrate. Penoizol is one of the best materials for insulation. It eliminates the appearance of fungus and mold. The only drawback is the high cost. However, it should be remembered that the period of possible use of the material is 70 years.

Bitumen mastic is most often used as a material for waterproofing pitched roofs. The coating distributed over the roof surface can form a base with excellent waterproofing parameters. It is also possible to use anti-condensation film, which is made on the basis of viscose. This option is most often suitable for roofs that are covered with profiled sheets.

Waterproofing is carried out after the rafter system and sheathing have been completed, and the insulation has been laid:


If the roof is not ventilated, then the waterproofing material should not be an ordinary film, but one with condensation protection. It is also possible to use a modern vapor-permeable membrane, which will remove excess water vapor to the outside. The waterproofing process can be facilitated by using a self-fusing roof. However, it is important to ensure that the coating material does not overheat.

Laying roofing

One of the popular options is the installation of roofing material made of roofing material.

Step-by-step guide to laying roofing felt

Roofing felt is mounted on a continuous sheathing. The material can perform two functions at once:

  • protect the interior from precipitation;
  • create a continuous budget coverage.

Ruberoid is a soft rolled material for roofing, so it is easy to lay. To reliably protect the roof, roofing felt must be installed in 2-3 layers. The first layer is used as a lining, and subsequent layers are used as the main coating.


In addition to roofing felt, other materials can be used roll type. They are laid out on mastic or fused using a gas burner. The second method requires increased attention, because it is a fire hazard. Such work should be performed by a person with experience.

Sequence of installation of corrugated roofing sheets

Corrugated sheeting has little weight, so it is possible to save on the manufacture of the rafter mechanism and sheathing. Rafter legs can be made from bars 100x30, 50x30 or 50x50 mm. The choice must be made based on the load on the rafter mechanism. To create a high-quality roof, it needs to be insulated and waterproofing material laid. Sequencing:

  1. Waterproofing is laid on the surface of the frame. In this case, it is allowed to use polyethylene film with a thickness of 200 microns. The film is fixed to the sheathing using thin strips with a cross-section of 20x20 mm. The distance between the slats should be such that the profiled sheet can fit tightly on the parts.

    For laying profiled sheets with a thickness of 0.4–0.5 mm, a sheathing pitch of 50 cm is sufficient

  2. A metal roof is laid on top of the waterproofing material. The corrugated sheets are secured to the sheathing using special self-tapping screws with rubber linings. For convenience, you can pre-drill small holes in the base. Self-tapping screws must be screwed in without tension so that the material can contract and expand with temperature changes.

    Sheets of corrugated sheets are fastened with roofing screws into the recess of the wave

  3. The roof is insulated from the inside of the garage. The process of insulation under corrugated sheeting is completely similar to that described above.
  4. Mounted on the inside of the roof vapor barrier film and finishing coating of the walls and ceiling of the attic.

Features of laying seam and slate roofing

Laying a seam roof made of galvanized metal is possible only if you have certain skills and special devices. It is not recommended to do this yourself.

A slate roof can last more than 40 years. The material is laid in the same way as corrugated sheeting, but slate has a lot of weight. Accordingly, he needs a strong and reliable rafter mechanism. Rafters must be made of wooden blocks with a cross-section of at least 100x80 mm.

Garage roof operation and maintenance

Soft surfaces are quite durable, but regular inspection of the substrate is recommended. Signs that indicate the need for repairs:

  1. Various mechanical damage: through abrasion, deep crack, burst hole.
  2. The appearance of depressions in which water or dirt can stagnate.
  3. Change in the appearance of the coating: the appearance of moss, mold or mildew.
  4. The occurrence of emergency delaminations at joints.

If these signs are present, it is recommended to have your roof repaired immediately. Experienced specialists recommend that garage owners carry out regular maintenance of the structure at least once every 3 years. In this case, it will only be enough to eliminate minor flaws. If the roof will be left in a neglected state for a long time, it may be necessary to complete replacement coverings.

Garage roof repair

The repair method depends on the type of roof and the degree of wear of the building. In private buildings, where the garage is located separately from the building, budget roofing materials with a long service life are used. Garages in cooperatives cannot be covered with profiled sheets or flexible tiles Therefore, soft bitumen-based materials are used. There are 3 options for repairing a garage roof:

  1. Using heated bitumen.
  2. Application soft material for the roof.
  3. Use of profiled sheets or tiles.

Before you begin repair work, you will need to remove debris from the roof and clean the areas that will need to be repaired. If the previously installed coating material can be used, then you will need to cut out the recesses in places with defects with an ax. If the roof was covered with roofing felt, then the structure must be inspected for cracks or swelling. Such defects must be eliminated before repair work.


When preparatory work will be completed, you can begin repair work:


Repairing a roof using roofing felt is quite simple. You will need to cut out several pieces of material and then use them to close the recesses. Each segment must correspond to the size of the recess. Sequencing:

It is quite possible to build a durable garage roof yourself, but it is important to follow the instructions and choose high-quality and reliable materials at all stages of the work.

Garage roof structures come in several types. In order to choose the best one, you need to familiarize yourself with the specific features of each of them. So, different variants mounted differently.

Peculiarities

A roof for a garage is different in many ways from a roof for a house. This is due not only to the fact that the garage is used as an additional utility structure, but also to the fact that there is no need for such high-quality thermal insulation. That's why the roofs are covered inexpensive materials, which do not cause difficulties during their installation.

A specific feature of the garage roof is that its shape and design are selected relative to the location of the garage house. In addition, it is determined by the stylistic coloring of the facade of the main house, as well as the surrounding landscape. However, it must be remembered that there should not be any special frills here, because the garage is still not the main structure, and in theory it should not attract too much attention to itself.

Due to the simplicity of the design, garage roofs will not cost much. This is due to the low cost of materials and repair work. Due to the ease of installation, construction work will cost little. Thanks to this same feature, installation can be done independently, without the involvement of specialists.

So high-quality insulation is not required, so this side detail can be easily dispensed with.

Kinds

This is not to say that garage roofing comes in a wide variety of types. Simplicity and functionality are the fundamental principles in accordance with which the choice is made in favor of one design or another. This is the reason for such a meager choice.

The choice in favor of one type or another is made based on several factors. Firstly, the climate zone in which the garage is built is important. How windy the area is and how much rainfall there is directly affects the choice of design and roof slope. Secondly, again, overall harmony is important. It is much better if the garage roof is similar to the one on the house. Thirdly, the chosen material plays a role. Some types look good only on roofs with one slope, others - with two.

Before choosing one type or another, it is necessary to analyze the situation with the construction of a garage. First of all, you need to know:

  • the climate in which the garage building will be located;
  • whether the garage will be adjacent to the house or separate;
  • what material is the roof made of?
  • height of the roof above ground level.

By answering each of the questions posed, you will be able to choose the best option that is suitable for your particular case.

Each type of roof has its own subtypes, which are also worth keeping in mind. The use of one or another subtype is determined depending on the area of ​​the roofing. Thus, it is possible to prevent the roof from collapsing, its subsidence under the weight of precipitation, and the load on the foundation is also regulated.

Flat

A roof with a slope height of up to 3 degrees is classified as flat. Compared to pitched roofs, it has a number of advantages:

  • a flat roof takes up much less space than a pitched roof, resulting in savings on materials for its manufacture;
  • a flat roof can be built much faster than a pitched roof, since complex calculations regarding the rafter system are not required;
  • repair flat design much easier and safer due to the fact that the risk of falling is reduced when sliding down a surface with a steep slope;
  • if the garage is attached to the house, then such a roof can be converted into a balcony or used as a terrace on the second floor.

However, flat roofs are not suitable for areas with strong winds and heavy rainfall, as they may fail and collapse under the weight of the snow. This also explains the fact that such a roof will have to be periodically cleared of snow and icy crust.

To drain water from such roofs, it is often necessary to organize additional drainage channels. The tightness of the roof is under threat: this must be constantly monitored, carrying out preventive maintenance every year.

Low slope

Low-slope pitched roofs are considered a universal solution. They are suitable for areas with an average climate. The garage may not be located in the city, but it should not be located in a windy steppe space. The slope angle of low-slope structures varies from 3 to 30 degrees. The advantages of such roofs are some features that will be discussed below. A special feature is that the slope for each specific case is determined through calculations, and the minimum acceptable value is selected. Calculations are made based on the roofing material.

When building low-slope roofs, several specific features will need to be taken into account:

  • The need to equip a drainage system of internal or external type.
  • The roof must have good tightness.
  • The need for a ventilation gap under the roof. Its size is determined according to the angle of inclination: the flatter the roof, the larger the gap.

Thus, choosing a low-slope roof guarantees savings on materials, but you will have to spend a lot more effort and money on the structure itself. Make sure that the choice of a low slope is justified in terms of aesthetic appeal.

Steeply inclined

The angle of inclination of steeply pitched roofs starts at 30 degrees. As with other options, this variety has both pros and cons. It is necessary to use roofs with a steep slope if the garage is located on windless areas (for example, in urban areas). If there is a lot of snow in the area, then such a roof will allow you not to waste time on cleaning it, because the snow will not linger on it, rolling down steep surfaces.

This option is completely unacceptable for windy areas. Thus, the roof can easily be blown away by a strong gust of wind. If the area is windless and there is little precipitation, then the costs of such construction will not be justified.

Thus, the choice of one or another variety is primarily determined by the location of the garage and the site as a whole.

For steppe windy deserts, it is best to choose flat or low-slope roofs; for wooded areas, low-slope options are best suited; and for urban areas with large amounts of precipitation, a steeply sloped variety is the best choice.

However, roofs are divided not only by angle of inclination. There is another classification of roofs - by the number of slopes. For garages, only two types are used: single-slope and double-slope.

Single-pitch

Shed roofing is valued for its simplicity and functionality.

  • Firstly, its installation actually takes less time than the construction of a gable version.
  • Secondly, it will not be difficult to make all the calculations for the required amount of material. This step can be taken independently, and the accuracy of the calculations will not be in doubt.
  • Thirdly, such a roof requires significantly less material than a gable structure of the same area.
  • Fourthly, a pitched roof - great option, if you need to arrange a garage attached to the house. She looks the most harmonious.
  • Fifthly, it is believed that pitched roofs are more durable than gable roofs. In addition, they are more reliable and stronger, and thanks to timely repairs they can last up to 50 years.

Mono-slope structures are not without their disadvantages.

  • Due to the fact that in most cases, single-pitch options are flat, the load on them increases in winter. Snow doesn’t roll off on its own, and you have to either clear it off yourself or trust that the roof will bear it.
  • With the lean-to option, you will definitely have to abandon the attic, even if a small attic space was initially planned.
  • This variety is more difficult to equip with decent thermal insulation.
  • Many people notice that the single-pitch structure looks rustic compared to the expressive gable one, and in some cases this causes certain inconvenience to the owners.

Gable

A gable roof is more often used for detached garages. See it on a structure attached to a house - very rare. Nevertheless, gable options have their advantages.

  • Thanks to its special shape, such a roof does not retain snow and rain. They roll down instead of weighing down the structure.
  • Although a gable roof is more complex than a single-pitch roof, you can make a garage version yourself if you take into account some adjustments.
  • By choosing the basic option, you can save a lot on work, since you will be able to complete it alone, or at most with a partner.
  • The gable design allows it to be equipped with good thermal insulation, thereby reducing heat loss. So, when planning a warm garage, other roofing options cannot be considered.
  • The gable roof allows you to organize a small attic where you can store tools and other equipment. In cases where a mounted gable design, it turns out to increase the ceiling height.

Having assessed exactly how you want your garage to look in the end, you can easily choose the type of roof structure for it.

Materials

Roofing materials are not only those on the outside. For internal construction, their own types are also used. If the rafters can be made from wooden beams, then several materials are suitable for waterproofing. Most often, roll insulators are used for this, for example, bikrost, roofing felt, roofing felt. Instead, you can use bitumen mastic, which will reliably protect the roof from water penetration.

But it is also important not to buy too expensive materials for covering the garage roof. For example, a garage roof lined ceramic tiles, will look strange and inappropriate. If the roof of the main house is finished with such an elite material, it would still be better to choose a cheap equivalent for the garage. This will show both the good taste of the owner and his practicality, allowing for significant savings.

For internal wooden structure there is also an analogue - concrete frame. It should be kept in mind that Concrete is much heavier than wood, the load on the foundation of the building will increase significantly. In this regard, before choosing such an alternative, it is necessary to ensure that the strength of the structure is sufficient.

Corrugated sheet

One of the most common materials used to cover a garage roof is corrugated sheeting. This type is so often used due to a number of advantages, including - big choice colors, price, ease of installation. In addition, the corrugated sheet is durable. If you lay it properly, a durable, aesthetically attractive coating will be guaranteed.

Corrugated roofing differs in the height of the corrugation, the width of the sheets themselves and the type of galvanized steel used in production. The material of the NS category belongs to the roofing class, so when choosing, you should definitely look for this particular marking. Please also pay attention to the presence of the GOST mark. If it is not there, this means that during production other standards were taken as a model or there were no standards at all. From this we can conclude that corrugated sheeting without such a symbol is not always of high quality.

For the roof it is necessary to choose profiled sheets with polymer coating. Polyvinyl dichloride, pural and polyester are considered suitable. The first is the most durable sample, but its cost is slightly higher, but the other options are cheaper, but less wear-resistant.

Slate

Gray dull slate material has long become a classic of the genre, and when we're talking about about slate, everyone imagines just such roofs. Despite its unattractive appearance, slate has excellent strength characteristics. If you choose a high-quality sample made in accordance with modern technologies, it can easily last up to 50 years.

  • Slate is made from different types of raw materials. Plastic, asbestos-cement, soft, rubber and metal are used. Each of these subcategories has its own characteristics and advantages.
  • For example, the asbestos-containing option has excellent technical performance and low cost, but asbestos is toxic, and this type of slate is harmful to health.
  • Soft slate does not have frost resistance, but it is strong, durable and at the same time flexible.
  • Plastic slate lasts up to 15 years without loss of strength, but it must be installed carefully, given that it tends to either shrink or expand depending on temperature changes.

Nowadays there is a wide variety of decorative solutions on the market, and you can choose slate material of any color.

"Ondulin"

The company name Ondulin has long become a household name, which is used to designate roofing sheets that imitate other materials. There are three types of them that are most popular.

  • Smart. The material has a small mass, as a result of which it is possible to carry out installation alone, without the help of a partner. Thanks to optimal size sheets and their small thickness of only 3 mm, you can completely sheathe the roof of a garage in one day. It will take a lot of nails. And also when working with Smart material, the joints will need to be covered with additional decorative elements.
  • Diy. This variety is more rigid than the previous one. This is due to the fact that the waves here are more frequent and higher. The mass of the material remains the same. So, similar options more suitable for roofs of complex architecture, rather than for elementary ones garage structures. The material is laid overlapping, due to which its consumption increases.
  • "Tile". Finishing with this type of sheet is indistinguishable from finishing with metal tiles, but it is much easier to implement than laying out real tiled roof. Presented a large color variety options, and there are not only plain roofs, but also spotted ones.

Steel roofs raise more questions than all others.

  • Firstly, they are not strong enough. Any severe mechanical damage will easily warp the overly flexible material.
  • Secondly, steel does not hold temperature at all, as a result of which it will be necessary to take additional care of the heat-insulating layer.
  • Thirdly, the waterproofing is also not at the proper level: the roof can easily begin to leak, jeopardizing the safety of your car. The roof will need to be additionally sealed.

However, seam steel floors have several significant advantages. In the first place is the price: it is an order of magnitude lower than the cost of other options. Repairing this roof is also easy, since the panels are fastened to each other using ordinary tucks. The roof can be covered with this material even in winter. Due to its flexibility, steel is ideal for winter installation. So, because of all this, seam roofing coverings confidently remain on the list of the most popular among all materials for the design of side buildings.

Ruberoid

Roofing felt is laid on a continuous sheathing. Its advantage is that it is sold in rolls, and there will be no installation difficulties. However, there are several pitfalls here too.

  • It should be borne in mind that the material consumption will be impressive. Roofing felt is laid in three layers, which are coated with bitumen mastic for better thermal and waterproofing.
  • The service life of the material is 15 years, after which it will need to be dismantled.
  • The material is mainly used for finishing flat roofs. Roofing felt coating cannot be called aesthetically attractive: when pitched roofs are sheathed with it, they are additionally covered on top with some material with better decorative properties.

Ruberoid for roofing is produced in four main categories, which differ in the type of base.

  • Rubemast gives the coating durability due to the fact that it is more flexible and less susceptible to cracking.
  • Fiberglass ruberoid or steklomast has characteristics similar to rubemast, but it is based on fiberglass rather than construction cardboard.
  • Roofing felt is practically not produced, since it lags far behind in quality, but in terms of production price it is on par with other types.
  • Euroroofing material has a complex structure. This material is the newest of all, and its qualities greatly exceed those of traditional roofing felt coatings.

Polycarbonate

This variety is of greatest interest due to unusual looking. The peculiarity of polycarbonate roofs is that they are transparent. Depending on which type of polycarbonate is chosen, the degree of transparency varies. Thus, the surface can be from slightly cloudy to practically impervious to light. Based on their structure, there are monolithic and cellular polycarbonate slabs. The first option is cheaper, but the second does not require additional thermal insulation.

Polycarbonate is resistant to all kinds of influences, both physical and chemical. It is non-flammable, so it can be considered a fireproof material.

However, it is worth keeping in mind that if you plan to make a warm garage, polycarbonate will not work. Due to the installation of additional thermal insulation, all its decorative qualities will be lost, and the result will not please you as much as it could. If you need a warm garage, then it is better to make the roof from a cheaper material.

Slope angle

The installation of a roof involves complex calculations, including raising the roof. Regardless of whether a gable or single-pitch structure is chosen, lifting is mandatory. The only exception is flat roofs, but there is always a slight slope of a couple of degrees.

The height to which the roof needs to be raised is determined by many factors. An important detail is how exactly the slope will be located. note that It is optimal to place the slope on the windward side. It doesn’t matter whether the garage is closed from the wind by other structures or a fence - this rule is immutable.
