Harsh climates with frosty winters and heavy snowfalls create additional challenges for roofing structures. Snow on the roof creates a cap with a large mass, which overloads and even deforms the rafter frame. When going off the ramp snow cover with pieces of ice a real avalanche is formed that can damage roof covering or cause injury to people passing by. They will help stop this spontaneous decline special devices, the requirements for which are described in SNiP II-26-76. In this article we will tell you how to choose and install snow guards on the roof with your own hands.
A snow retainer is a device used to hold the snow cap that has accumulated on the roof during a snowfall. It stops the fall and keeps the snow on the slope until it melts under the influence of sun rays and ends up in the drain. Snow guards are a small barrier or fence installed along roof overhangs. They perform the following functions:
- Protects the integrity of the roof covering. Ice that forms on the roof when heated inner surface slopes with heated air, when thawing and sliding, damages the roofing material, leaving scratches. In these places, devoid of a protective layer, pockets of rust appear. Roofs that use metal profiles as a covering especially suffer from this.
- Protects passersby, plants and equipment from snow falling on them. The snow mass, which often contains pieces of ice, comes off the slope at high speed; it can cause significant damage to a car or person. Therefore, SNiP II-26-76 requires installation with a slope of more than 6 degrees.
- Prevents deformation of the external drain. In homes that do not have snow guards installed, gutters are often damaged when snow melts. The brackets can't stand huge load to which they are exposed.
- Protects the roof rafter frame from overload. Properly installed snow retainers in areas with a large snow load do not stop the melting of the layer, but divide it into small plates and reduce the rate of fall. This measure makes the process safe and at the same time does not overload the rafters, since the weight of the snow cap in some regions can reach 300 kg/sq.m. m.
- The snow cap, preserved on the slopes by snow retainers, becomes a kind of thermal insulation, retaining heat inside the house, which saves money spent on heating. This function of snow retention is relevant for roofs made of metal tiles, since the metal profile has high thermal conductivity.
Note! SNiP requirements recommend the installation of snow guards along all roof overhangs. However, there is an opportunity to save money - you can install snow barriers only in special important places(driveways, plantings, parking lots, entrances).
Kinds
Different types of roofs and specific climatic conditions require a special approach when installing snow retention elements. Therefore for efficient work systems that limit the flow of snow from slopes, devices with different functions and appearance were developed. The following types of snow guards are popular in private housing construction:
Important! According to SNiP, devices used to prevent spontaneous snow falling from the roof are divided by function into snow barriers and snow cutters. A group of snow barriers, which include plate, corner and rope models, are designed to preserve the snow layer on the surface of the slope until it melts. Snow cutters are devices used to divide the snow cap into plates, the fall of which does not cause harm.
DIY making
Installation of snow guards requires certain capital investments, since the average price of 1 linear meter of fencing complete with fasteners is 300-400 rubles. To make this event more economical, you can make them yourself. The easiest way is to make corner snow guards. To do this, you will need a sheet of stainless steel with a polymer coating, scissors or a hacksaw for cutting metal, a drill, a sheet bender, a marker and a ruler. The task is performed as follows:
Advice from experienced craftsmen: professional roofers, when assembling the rafter frame at the site of installation of snow retention elements, must reinforce the sheathing with 1-2 additional boards, which are necessary to distribute the load and prevent deformation of the roof.
Video instruction
From this article you can find out what roof snow guards are: purpose and existing species products, their characteristics and rules of use. The text contains detailed description corner, tubular, lattice, as well as point snow catchers and the basic rules for their installation on metal tiles, soft, seam and other types of roofing.
Avalanche-like snow falling from the roof is a common problem in regions where winters are accompanied by large amounts of precipitation. To solve it we use special devices- snow retainers. These structures retain precipitation on the roof, which, as it melts, gradually flows down the gutters.
There are several types of snow guards. These products are selected taking into account several factors:
- roof type;
- roof angle;
- thickness of snow cover characteristic of the region.
Consumers can buy snow guards for the roof along with the roofing material when the house is still under construction, or purchase them as additional equipment for a finished building. These devices may go by different names depending on the functions they perform.
Snow blocking barriers ensure complete retention of precipitation on the roof. They are also called snow barriers. In this case, even partial melting of layers of snow is impossible. Accumulated precipitation will melt and leave the roof naturally.
Snow cutters serve a different function. They are designed to cut a layer of snow into several small pieces. Thanks to this, the energy of the avalanche will be minimal and safe.
Snow guards differ not only in the material they are made of, but also in their shape, size, and degree of reliability.
Consumers can buy snow guards of the following types:
- Lattice.
- Corner ones.
- Tubular.
- Spot.
In addition, you can make protective structures for the roof yourself. Wood is most often used for this.
Helpful advice! When choosing snow catchers, you must pay attention to how much snow the design is designed to hold. Otherwise, it will not be able to fully perform its function and ensure safety.
Universal tubular snow guards 3 m: price and design features
Tubular-type products are made of brackets and a pair of pipes, the diameter of which is 1.5-3 cm. The height of this structure is 15 cm. The bracket has the form of a vertical plate in which holes are made for installing pipes. There is a shelf at the bottom of it. It is used to fix the snow guard on the roof. Metal screws with a hexagon head (0.8x6 cm) are used as fasteners.
The appearance of the bracket may vary. It depends on the type of roof where it will be installed. It is advisable that there be a distance of about 2-3 cm between the roof surface and the first pipe, and 8-10 cm between the pipes.
Tubular structures cut the snow layer into several parts. They are reliable and can handle a lot of pressure. This category of products can be considered universal, since tubular snow cutters are suitable for almost any type of roof:
- sheet;
- soft;
- tiled.
Installation of structures is carried out along the slope along the entire perimeter of the building. In this case, the products are not arranged staggered, but in a row. If the snow load in winter is high, you can install two rows of protective structures at a distance of 2-3 m from each other. Moreover, the lower one is fixed with a distance of 0.4-0.5 m from the eaves overhang. The shade of the snow guards can be matched to the roof, so after installation these structures are not noticeable.
For the manufacture of tubular snow guards, galvanized steel is most often used. The top is covered with paint that matches the color of the roof. Thanks to this, the product not only fits into general form buildings, but also turns out to be durable. Moreover, the paint provides protection against corrosion.
Average prices of tubular type snow guards:
Note! Tubular fencing is suitable for roofs with a large slope (up to 60°), where snow movement often occurs due to high pressure. If the roof slope exceeds this figure, there is no need to install snow guards, since precipitation does not linger on the surface, but immediately crumbles.
Features of lattice snow guards on the roof: price and characteristics
Lattice snow retainers in a universal design have the form of brackets on which the lattice is fixed in a vertical position. All parts of the product are made of galvanized steel, opened coloring composition, which allows you to choose a design to match any color of the roof.
The size of the gratings may vary. The most great options have a height of about 15-20 cm. The size of small gratings does not exceed 5-7 cm. The level of strength and the ability of the structure to hold a certain volume of snow depend on the size of this part. Large steel gratings can withstand the weight and pressure of large amounts of precipitation and ice. As a rule, snow retention on the roof is ensured at all times. Precipitation leaves it only in the form of melt water.
Lattice-type products are mounted on long roof slopes with a large slope. The presence of such a design ensures that blocks of snow will not fall on the heads of passers-by. The effectiveness of the grille depends on its height. There are no restrictions regarding the roofing material, since all types of fasteners are provided for this type of protective structures.
On sale you can find snow guards where the grille is welded to longitudinal pipes. This configuration improves the reliability of the product. Installation of lattice structures is carried out on a slope along the eaves. If the snow loads in the region are large enough, other types of protective barriers, for example, plate snow barriers, can be installed as an addition. The same applies to cases where the length of the slope exceeds 5.5 m.
The average price of lattice structures for natural tiles (ceramic or cement-sand) is 4,250 rubles/piece. Purchasing products intended for standing seam roofing will cost approximately 3,200 rubles/piece.
Note! Under the pressure of a large amount of snow, the gratings may bend. In this aspect, tubular structures are more reliable. The strength of lattice snow guards depends on the shape of the guides or brackets, as well as their quality. You should not buy products where these parts have the same thickness as the grille.
Plate or corner snow guards for metal tiles
If a small amount of precipitation accumulates on the roof, you can limit yourself to purchasing corner snow guards. Most often they are used on roofing made of corrugated sheets or metal tiles, since these products are made from similar material and in the same colors.
Corner metal constructions have a bent triangular shape with two edges, equipped with shelves for fastening. The height of snow guards of this type is 4-6 cm. Corner fences are designed for roofs with a slight slope (no more than 30º), since the structures are not able to withstand high pressure.
The products are attached directly to the roofing material; the upper wave of the covering, where the fences are also fixed, is no exception. Installation of snow guards on a metal roof is carried out along the ridge. This is done in a checkerboard pattern. The products will be placed in several rows (minimum 2) in increments of 0.5-1 m.
Corner type snow guards are not very durable. They will not be able to keep large amounts of snow from sliding down. Therefore, these products are used only in those regions where there is little precipitation in winter. In addition, you will need to regularly clean your roof. The cost of such snow guards is 290 rubles/piece. (2 m).
Specificity of yokes - point snow retainers for the roof
Point snow retainers are called yokes or hooks. They are not designed to hold large amounts of snow, so they are used as a complement to tubular and lattice structures. Installation on a soft-covered roof with slight slope.
Related article:
Description of the most common roofing materials various types and types. Application and installation features.
A soft roof facilitates the accumulation of snow because it has a rough surface in the form of granules. Precipitation is well retained on roofing felt and bitumen shingles.
Note! If the roof has a slight slope, then snow drift is unlikely. Nevertheless, for safety purposes, it is advisable to install yokes in a checkerboard pattern with a pitch of 0.5-0.7 m.
Point snow retainers look like triangles with a long plate. It is used to fix the product on the sheathing. The installation of these snow guards for soft roofs is carried out so that the plate is located directly under the roofing material. Layered on top bitumen shingles will hide all fixation points. As a result, the possibility of roof leaks is eliminated. The average price of point stupors is 50-60 rubles/piece.
Snow guards for the roof: installation technology and features of its implementation
Such objects include:
- parking area for cars;
- balconies;
- pedestrian paths;
- attic windows.
The installation area is selected taking into account the fact that a snow avalanche, when descending from a roof with a slope of 35°, covers a certain area. As a rule, precipitation falls at a distance of 0.5-1.5 m from the overhang.
Snow guards are installed at a distance of 0.5-0.8 m from the eaves overhang. It is not allowed to place the protective structure directly on the overhang. The exception is when the cornice is formed by the roof truss system.
Important! Installing snow guards on or near an eaves will cause a collapse.
The cost of products depends on their type, size parameters, material of manufacture, as well as manufacturer. The most popular brands are Borge, Grand Line, Orima.

How to properly install snow guards on metal tiles
Metal tiles are the most popular roofing material. Its configuration allows layers of snow to constantly fall off the roof. Smooth surface unable to retain precipitation. At the same time, the roofing material reacts sensitively to temperature changes. Metal tiles help melt the snow, causing the entire layer, along with the ice, to begin to slide down. Therefore, installation of snow guards is mandatory.
The following structures are installed on metal tile roofs:
- corner;
- lattice;
- tubular.
Corner products are suitable for winters with little snow. In other cases, it is better to give preference to lattice and tubular structures. They are durable and easy to install.
How to install snow guards on metal tiles:
- Applying markings in the installation area.
- Strengthening the lathing structure with an additional bar.
- Assembling the guard kit (without tightening the bolts).
- Installation of roofing material.
- Forming holes for fasteners in the lower wave adjacent to the sheathing structure.
- Sealing the holes with rubber pads.
- Fixing the bracket on the slope using bolts (0.8x6 cm), taking into account its length and slope. The greater the slope, the tighter the brackets are installed. The optimal step is 0.5 m.
- Installation of pipes into brackets. If you are installing lattice snow guards, then adjacent structures should be connected to each other.
Protective products are secured over load-bearing wall. In the accommodation area dormer window The sheathing must be strengthened. Some snow guards have additional benefits. For example, for Monterrey metal tiles, snow guards with special brackets are provided. They have special protrusions that make it possible not to strengthen the sheathing structure.
Important! Installation of lattice and tubular type snow retainers is carried out through the roofing material.
How to install snow guards on a corrugated roof
Corrugated sheeting has almost the same characteristics as metal tiles. Its surface is smooth and sensitive to temperature changes. The need to install snow guards in this case is due not only to safety considerations. The snow that melts during the day freezes in the evening and, slipping, scratches the corrugated sheet. As a result, the protective galvanized coating is damaged, which leads to the development of corrosion.
Plate, lattice and tubular type structures can be installed on corrugated roofing. The latter are used most often because they are made of galvanized steel and can be painted to match any color of the roofing material.
The installation technology is practically no different from the procedure for installing snow guards on a metal roof:
- The structure is fixed through the roofing material.
- The sheathing is strengthened.
- The holes for fasteners are sealed using gaskets made of weather-resistant rubber.
The fastenings should be placed at the bottom of the covering wave, where the corrugated sheeting is adjacent to the sheathing. Otherwise, the sheet will be deformed. If it is planned to install protective structures on finished roof, to strengthen the sheathing, you will have to partially disassemble it. Lamellar or corner products are installed in the upper wave of the profiled sheet. They do not require additional reinforcement of the sheathing. In this case, the clamps are placed through one wave.
How to install snow guards on a seam roof
On a seam roof, exclusively lattice and tubular snow retainers are used as protective structures. The installation system of the latter differs only in the method of attaching the bracket, which has a specific shape. In this case, the part is fixed directly to the seam, thanks to which the roof covering retains its tightness.
Installation of snow guards is carried out using clamps:
- A clamp is placed on the fold.
- A couple of holes are made (sometimes 3).
- The structure is fixed to the roof using bolted connections.
The advantage of this technology is that there is no need to reinforce the sheathing. Installation work carried out on top of the laid roofing material. As a result, the structure is strong and reliable, since the pressure of the snow layer will be distributed along the fold.
Helpful advice! The pitch at which the supports are installed depends on the slope of the roof. To get a reliable result, it is advisable to secure them to each fold.
To manufacture protective structures for seam roofs, not only galvanized steel is used, but also copper. In the latter case, the products are not sold as a set, but as piece goods. The consumer can purchase the upper and lower brackets, as well as a piece of pipe. The cost of copper snow guards is quite high, but they fit better into the design of a seam roof, which is also not a cheap pleasure.
Features of installing snow guards on a roof with a soft surface
Soft roofing requires special handling. The maximum permissible slope angle for such a roof is 15°. In this case, the likelihood of an avalanche of snow is eliminated. For this reason, tubular snow catcher designs are very rarely used on soft-surface roofs.
Stone chips on the surface of the covering prevent the movement of snow and retain precipitation on the roof. On soft roofs, continuous sheathing is usually used. It is made from sheet plywood with moisture-resistant properties, so it does not need reinforcement. Snow guards are installed during the installation of roofing material. Most often, point snow retainers are used, in rare cases - tubular ones.
The technology for installing tubular structures is the same as in the case of installation on metal tiles or corrugated sheets. Although this system It also has a drawback, since the fasteners are located on top, thereby violating the tightness of the coating.
Installation technology for stoppers and triangular yokes:
- Products are placed in 2-3 rows in a checkerboard pattern. Installation step – 0.5-0.7 m.
- The yoke is fixed to the lathing structure so that the fastening plate can overlap the next sheet soft covering. In this case, the triangular part of the yoke remains outside (on top of the roof).
- The snow guard is fixed using self-tapping screws.
If the roof was installed previously, point snow guards can be installed on top. In this case, the use of weather-resistant rubber gaskets is mandatory.
Technology for creating snow guards on the roof with your own hands
Installation of snow retention structures on the roof is accompanied by a number of advantages. These simple devices have big amount beneficial advantages.
Snow catchers perform the following functions:
- protection of roofing materials and drainage systems from damage;
- effective removal of a heavy snow cap, which can cause deformation changes and roof sagging;
- preventing the appearance of water stains on the ceilings of rooms located on upper floors building;
- protection decorative elements and plantings located under windows;
- protection of cars parked near the building from snow drift;
- protection external plaster, which can be spoiled by melt water if sudden warming occurs.
Helpful advice! Even if there are snow catchers on the roof, it is advisable to clean the roof on a regular basis (every 1-2 weeks). To eliminate the need for this event, you can lay a heating cable under the roof. Thanks to it, the snow will quickly melt and flow down the drain without lingering on the roof.
Recommendations for making corner snow catchers for the roof
To save money, you can make corner-type safety fences yourself and install them on the roof. This option is considered the easiest to implement.
To do this you will need the following tools and materials:
- metal scissors or hacksaw;
- leafy stainless steel with polymer coating;
- sheet bender;
- ruler and marker for marking;
- drill.
To begin with, a drawing with dimensions is selected. Based on it, a template for a corner snow retainer is created. After this, using a ruler and marker, the markings are transferred to the sheet steel. This must be done so that after cutting there is as little waste as possible.
In accordance with the markings, the metal is cut using a hacksaw or scissors. You should not use a grinder for these purposes, even if the master has good experience handling her. As a result of cutting with this tool, the protective coating on the metal is damaged, which prevents corrosion.
At the next stage, the workpiece needs to be secured on the work table. Using a sheet bending machine, bend the product along the marking lines. The result should be a corner with two shelves for fastening, the height of which is 15-20 cm. Self-tapping screws will be used to fix the snow guard. Holes should be made in the mounting shelves for them.
Corner structures are mounted in a checkerboard pattern. If the length of the slope is less than 4 m, it is enough to install snow guards in two rows. If this figure is 6 m or more, at least three or four tiers of barriers will be required.
Manufacturing technology of lattice snow retainers for the roof of a private house
Lattice structures are more complex to manufacture than corner ones. This will require skills in handling an angle grinder and a welding machine.
Scroll necessary tools and materials:
- metal corner;
- stainless steel for creating a lattice;
- Bulgarian;
- metal pipes suitable diameter;
- welding machine;
- suspension type supports;
- building level.
First, a drawing is drawn up. He must take into account the parameters of the roof and all related factors. A corner should be used to make the grille frame, and pipes should be used as a reinforcement. The steel is prepared and markings are applied on top of the material. After this, all the details are cut out using a grinder.
The corners should be placed to form a rectangle. After this, you can secure the upper part of the frame by welding. It is very important to ensure that there are no distortions. If there are no defects, you can weld the corner parts of the frame. Then the pipes are fixed. They should be positioned vertically in relation to the corners and welded. Having made required amount structures, you can begin their installation. First you need to install suspended supports on the roof.
Supports for homemade designs, as for factory-produced snow guards, can be purchased at hardware store. Using these simple devices, you can avoid many problems associated with avalanche-like snow falling from the roof.
The modern owner should know about the benefits of using snow guards in the fight against natural elements. The article contains useful information about the criteria for selecting snow retainers for the roof and about the intricacies of installing the system on a metal tile roof. You will get acquainted with the popular types of snow retention systems, from tubular and angle, to lattice and rope.

The need for a snow retention system
To the roof country house there are many requirements, it must be reliable, practical and beautiful; Another mandatory characteristic of a roof is its safety. It is this quality of the roofing structure that sharply deteriorates in cold season in places characterized by long and snowy winters.
Weightless, fluffy snow flakes, falling on the roof, have the unpleasant property of lingering on it and, over time, compacting. Behind short term The snow layer grows to a considerable thickness, having time to thaw several times and then freeze again. As a result, a dense and heavy layer of snow with layers of ice is formed, ready to slide (and slide!) off the roof surface at the most inopportune moment. If at this time there is a person, animal or, for example, a parked car under the roof, falling snow can cause (and, unfortunately, often causes) considerable damage. Plants planted near homes may also be affected.

The problem of sudden snow melting is common for residents of northern countries, and snow retention on the roof of a house is standard solution Problems. For this purpose, snow retainers are used, special devices that do not allow the snow to completely disappear at one time. In addition to preventing sudden snow melting, the device also performs some additional functions:
Makes the roof easier to clean from the snow.
Protect drainage system from violating the integrity of connections and breaking off fasteners.
During the thaw keep snow off the roof, allowing it to melt and flow down the drains safely.
Protects canopies and awnings buildings (falling pieces of ice, compressed snow and icicles can seriously damage them).

Operating principle of roofing snow blocking systems
The installation of snow guards on a metal tile roof is especially relevant - a smooth polymer surface cannot seriously prevent the snow mass from sliding off. If the bottom layer of snow has turned into an ice crust (which happens in 70-80% of cases), when it melts it will inevitably damage the surface of the sheet. Scratches will become sources of corrosion and the roof will not last as long as it should.
Three factors influence the choice of snow retention system:
Slope angle.
Snow cover amount, characteristic of this region.
Type of roofing.
The snow guards on sale can be divided according to the operating principle into two groups:
Snow cutters. This design is designed to let snow through in small portions, piece by piece. The principle of its operation is not to stop (and accumulate) a layer of snow, but to divide it into fragments. Advantage of the design: a large mass of snow does not accumulate on the slopes, loading the rafter frame. It fades gradually and is not capable of causing damage. Another plus is that snow cutters can be mounted on roofs of any steepness.
One of the options for placing snow guards Source remoo.ru
Snow barriers. They completely block snow melting; so that the accumulated snow cushion does not deform the roof and rafter system, snowdrifts will have to be manually removed regularly. Installation of snow retention barriers is justified only for durable, solid bearing capacity, designs.
Roofing snow retention systems: popular design solutions
As a rule, snow blocking systems are purchased at the stage of housing construction, simultaneously with the roofing material (but nothing prevents you from purchasing them later). You can choose products from one of the following types:
Lattice. Such designs are widespread and are successfully used for different types roofing, including metal tiles. There are several types of products on the market, differing in complexity of execution and features of supporting parts. Relatively high gratings can perform additional function: serve as a safety barrier in summer, during repairs.

Corner(lamellar). A budget option, which can be selected if snow accumulations are insignificant. Angle-type snow guards are easy to design and install, which makes them popular, including for metal tiles. Looks like a galvanized steel corner; wide range of shades of protective polymer coating allows you to select products that best match the color of the roof. They are allowed to be used on roofs whose slope angle does not reach 30°.

Tubular. If snowy winters are common, tubular construction is an ideal choice, especially for standing seam or metal roofing. In case of frequent and prolonged snowfalls, it is recommended to install tubular structures in several rows.
Tubular design Source zemeljka.ru
Spot(tow ropes). Relatively the new kind devices for regions with light and medium snowfalls. They evenly distribute snow pressure across the roof and additionally serve as support for the feet. Various roofing materials require the use of products of a certain shape; snow retainers suitable for soft roofs cannot be installed on metal tiles.
Made from polycarbonate ( gear). They are a type of point snow retainers; The products are transparent, non-corrosive and easy to install.
Budget option Source stroypay.ru
Horseshoe snow guards. A type of point system; has a characteristic curved shape and is made to fit certain metal tile profiles, which makes installation easier.
Snow retainers-logs. The original systems that protected alpine dwellings from snow and in some places have survived to this day; in the modern version, the role of logs is performed by metal pipes with a diameter of 130-150 mm. The tubular design effectively holds the snow layer, confidently coping with high pressure.
Criteria for selecting and calculating the system
In order for the snow blocking system to adequately perform its functions, the type, number and location of snow blocking devices is calculated based on the rules of SNiP 2.0.10.07.85. Proper installation involves drawing up a project for the location of blocking elements on the slopes. This approach helps to avoid that unpleasant situation when it turns out that under drilled hole there is no sheathing.

About Finnish polycarbonate snow guards in the following video:
System parameters are calculated based on the following conditions:
Roof type and angle of inclination. The greater the angle, the more pressure the snow will exert on the system. If the angle exceeds 15°, experts recommend installing tubular-type snow guards as the most reliable.
Surface area of slopes and type of roofing material.
Precipitation V winter period in this area. Maps and tables have been developed showing average snow load values by region.
The result of the work is a diagram of the arrangement of snow retention elements on this type of roof. It defines the following parameters:
Type of snow retention elements.
Mounting location. The system is installed parallel to the eaves overhang, with the first row placed above the load-bearing wall; this helps to minimize the load on the overhangs. The remaining tiers are mounted one and a half to two meters from the first.
Places for mandatory attachment of snow guards Source stroimmaster.ru
Number of rows and pitch between fastening elements. The distance between the brackets is determined by the length of the slope and the magnitude of the slope (the stronger the slope, the closer the parts are located to each other).
Fastening order. Tubular, lattice and plate-type systems are installed in rows; rope and corner - in a checkerboard pattern.
Color. If focusing on a snow retention system is not part of your plans, snow retention systems are matched to the color of the roof or one or two shades darker than it.
Equipment. The kit must include roofing screws and gaskets made of special rubber. They make the attachment points airtight.

Tubular snow guards for metal tiles
Metal tiles, due to their properties, are affordable, popular and therefore more widespread than other roofing materials. But its surface is smooth, sensitive to temperature changes, and is not capable of holding melted snow for any long time. This property makes the installation of snow retainers on a metal tile roof an urgent necessity. The following types of snow guards are suitable for metal roofing (as well as corrugated sheeting):
Lattice. Reliable, easy to install, varied in design.
Lamellar. Suitable for slopes with a small angle of inclination, they are more often used where winters are short and with little snow.
Tubular. Leading in frequency of use.
Universal tubular snow guard Source celinrmo.ru
Tubular structures are considered to be the most universal category. They are designed for high pressure, are reliable in operation, and safely separate the snow layer into small fragments. They are also widely used in the protection of tiled and soft roofs. Tubular snow guards on metal tiles are mounted following several rules:
Parts are fastened through the roof.
Installation is carried out after sheathing reinforcement, basics for securing system parts.
To prevent the metal tile sheet from becoming deformed, a hole is drilled in the concave (lower) part of the wave, in the place adjacent to the sheathing.
Mounting locations sealed with rubber gaskets.
If you choose plate or corner snow retainers, you do not need to reinforce the sheathing, since they are mounted directly into the sheet. Choosing models of snow guards that work on the principle of snow cutters allows you not to worry about timely cleaning of the roof - even in a strong snowstorm, the snow will melt off in safe portions.

Additional types of snow guards for metal tiles
In addition to the ubiquitous tubular snow blockers, other types of snow blockers can be installed on metal roofing, including:
Lattice. The design resembles tubular systems, only the role of retaining pipes is performed by a grid, the size of which (height) can vary. Such barriers hold back snow well, but sometimes they can bend under its weight. The grille copes especially well with its role on steep roofs (when the slope exceeds 35-40°).
Corner(lamellar). If the roof slope is small (up to 30º), and there is little snow in winter, you can limit yourself to installing a corner system. Corner snow guards have a height of up to 6 cm; on the roof they are arranged in several rows in a checkerboard pattern. The system is not designed to withstand high pressure, and the roof will require periodic manual cleaning.
Spot(yokes, hooks). They are used mainly on flat, rough (soft) roofs. On metal tile roofs, point systems are used as an addition to gratings and pipes.

Order turnkey installation of snow guards
The price of snow guards is comparable to the costs of periodic roof cleaning and repairs, which are inevitable in case of uncontrolled snow melting. Installation of snow guards on the roof is a popular service provided by many construction organizations, often in parallel with the installation of the roof. Turning to specialists allows you to obtain complete protection of the roof structure and the surrounding space. The price for installing snow guards is calculated per linear meter; it depends on several parameters:
Roof type and roofing material.
House heights, difficulty of access to the roof.
Vida selected system snow retention.
Scope of work(depends on the size of the roof and, therefore, the number of snow retention elements)
Necessities preparatory work.
Contacting the company allows you to get additional benefits:
The quality of the system is affected installation time, the best option in terms of price/quality ratio can be obtained simultaneously with the installation of the roof.

Why do you need a snow guard? Installing snow guards on roof surfaces helps protect against damage that can be caused by snow and ice falling from the roof. The principle of operation of tubular snow retainers is that they restrain the bulk of snow from an avalanche, passing it in small portions that cannot cause harm. It is especially important to install snow guards over pedestrian paths, crowded areas, parking lots and roadways.
Installation instructions for snow guards:
Step 1: Determine installation location.
Typically, the installation of snow retainers is carried out in the area of the first or second wave of metal tiles from the eaves. The basic rule that should be followed when determining the installation location is that snow guards should be located above the load-bearing wall to evenly distribute the load. Snow guards can be installed selectively - where falling snow layers are not desirable, or along the entire perimeter of the roof.
Step 2: Installation of fastening elements (supports) of the snow guard.
The snow guard comes with 4 supports, with which they are attached to the roof. Correct installation supports - the main stage in the installation of snow retainers on which the service life of roof safety elements depends. The installation step should not exceed 70 cm. The supports are mounted on the roof using hardware (included in the kit), 2 hardware per 1 support, while prerequisite Reliable fastening of the supports is achieved by getting the hardware into the rafters or roof sheathing. Otherwise, when the snow melts, the snow retainers will not withstand the load and will come off along with the snow.
Step 3: Insert the snow retainer tubes into the supports.
After the snow retainer supports are installed, tubes are inserted into them. The snow retainer tubes are connected to each other and extended to the required length; the junction of the two tubes is fixed with a self-tapping screw. The distance from the outer supports to the ends of the tubes should be 15-20 cm.

They come either complete with the roof or selected separately. The installation of one or another variation depends on their reliability, practicality, the amount of snowfall in a given area and, of course, on their compatibility in appearance with the roofing covering. Some hold the entire layer of snow, others seem to cut it into pieces, one model will withstand a layer of up to 20 cm in height, and the other will bend or break with this volume of snow, one model can be attached both along the edge and in the middle of the roof, and some exclusively on the edge.
