How to raise the roof of a house - general recommendations. Increasing the height of ceilings: raising the roof with jacks How to raise the roof of a house with a jack

Old buildings are low ceilings. If you are the owner of such a house and want to increase the height of the ceilings, you do not have to dismantle the roof - you can raise it yourself. Our master class will help you with this.

Tools and materials for work

We will need:

at least three jacks (preferably oil) with a lifting capacity of 5 tons;
the corresponding amount of compressive strength wooden beams, metal channels (optimally) or pipes of suitable length;
the corresponding number of rigid floor pads, which will redistribute the point load from the jack to the area load (thick boards, pieces of channel, etc.);
cushioning material that will be placed under beams and jacks during the process of raising the roof (cutting boards, bricks, etc.): their quantity must be calculated so that it is enough for all beams on both sides to the full height of the roof;
the material from which the walls will be raised (brick, shell rock, adobe, etc.), as well as mortars(sand, clay, cement, etc.): their quantity must be calculated depending on the length of the walls and the height to which the roof will rise.

So, let's begin

As part of the first stage of work, it is necessary to adjust the jacks to ceiling beams. The beams may be initially visible or sewn up from below, in which case you need to calculate their position (it corresponds to the location power frame roofs) and mark on the inside of the walls so that you know in which places to install the jacks. There will be a lot of dust during the process, so the furniture should be covered or removed from the room.

We start from the corner. We install the jack on the distribution gasket strictly under the beam and slightly wedge the channel between the beam and the jack, extending the jack rod. The jack should still have a travel reserve of 5-10 centimeters for the upcoming lift. Next, you need to make sure that the channel is located vertically in all planes. If necessary, you can loosen the jack, adjust the channel and lightly wedge it again.

If you do not plan to sew up the beams in the future, place cushioning material between the channel and the beam to prevent damage to the beam. Now you can try to carefully lift the beam. Monitor the relative position of the jack and the channel. If you see that a break is occurring at the point of their contact, loosen the jack and move it slightly towards inner side fracture Do not ignore this break - under increasing load during lifting, the channel can jump out of the connection, which can lead to injury. If there is no break, extend the jack rod no more than 5 centimeters and secure this position by placing a spacer between the beam and the wall. Do not loosen the jack.

Repeat the same operation with all jacks on one side of the house.

The more jacks you have, the better - you'll save time on reinstalling them.

When all the jacks are raised by 5 centimeters, you can start again from the first to the penultimate one, raising them another 5 centimeters and increasing the thickness of the spacers between the beam and the wall. It’s not worth raising it any higher yet: if there is a large distortion, the roof may “move out” during the process of raising the opposite side.

Next, we weaken and rearrange all the jacks under the next beams, except for the last one, raised by 5 centimeters. We repeat the whole process from the beginning. When all the beams on one side are raised by 10 centimeters and spacers are placed under them, we move to the other side of the house and raise them in the same way. From this side you can raise it by 15-20 centimeters, and we also do all further lifts to the required height. In this way, the slight displacement that occurs when the roof is skewing will be compensated.

Additional complications

The first and last beams are usually hidden by the wall, so they will need to be lifted manually using an enlarged arm. It will be much easier to do this when the second and penultimate beams of the house are already raised by 5 centimeters.

The distribution gasket under the jack must be strong enough to avoid damage to the floor covering.

Fix the roof at the required height

When the beam is raised to the required height, a support must be erected under it. Even if you use clay when laying openings, it is better to use mortar to build supports, since it dries faster and acquires the necessary strength. The support will have to be erected at the moment when the beam rests on the raised jack; after the jack is loosened, the load will immediately fall on the support - the freshly laid clay at this moment will most likely cause subsidence.

Particularly difficult will be the sections of the wall where the beams lie above window openings. You will probably want to increase the height of the windows, which will require raising the lintels and filling in the voids while the beams are resting on the jacks.

Try to organize the entire process efficiently so that it takes as little time as possible. While the roof is on temporary supports, it is a rather shaky structure - a gust of strong wind can ruin the result of your work.

After internal masonry laid, and the roof stands firmly, you can raise the facing masonry.

Since lifting and repairing a roof is a rather labor-intensive task, you should immediately think about updating the roof so that this issue no longer bothers you.

A common problem in many homes old building are low ceilings. If you are the owner of such a house and want to increase the height of the ceilings, you do not have to dismantle the roof - you can raise it yourself. Our master class will help you with this.

Low ceilings are a problem in many older private houses. If you bought such a house or are its owner, the ceiling height can be increased without dismantling the roof. You can do this yourself, with one or two assistants.

But first you need to be well prepared for this work. To do this, we will need at least three oil jacks with a lifting capacity of 5 tons, the more the better. Logs, beams, metal profiles (pipes, channels, I-beams) can be used as racks. We will prepare spacers from thick boards or the same channels for the floor, and under jacks and ceiling beams.

We will also take care of the material with which we will build up the walls: brick, adobe, foam blocks (about wooden house out of the question now). Don't forget to buy cement and sand to prepare the solution. All materials should be enough for full cycle work because they need to be done as quickly as possible. Otherwise, a strong wind can undermine the roof, which is supported by gaskets, and add a bunch of new problems to the owner.

If everything is ready, you can start slowly. We determine where our beams are (in some houses they are sewn up, in others they are visible from the outside). We start from the corner. We will need a stand (channel, log, beam) and three spacers: under the channel on the floor, between the jack and the channel, and between the jack and the beam. The axis must be strictly vertical, otherwise the stand and the jack will begin to warp, the latter may jump out and cause injury. Therefore, be extremely careful. If the work is skewed, loosen the jack and straighten the entire structure vertically.

After making sure that the vertical position is maintained, carefully extend the jack by 5 centimeters, no more. Place a spacer between the wall and the beam. Do not loosen the jack. Take the next jack and lift the adjacent beam. Having pulled out all the jacks, you can again move to the corner where you started, raising the beams another 5 centimeters and laying gaskets of greater thickness between the beams and the wall. Now we move to the opposite wall and perform similar operations, lifting the beams 5 cm each and installing spacers between the beams and the wall. From this side they can be raised by a total of 15-20 cm.

The end beams usually go above the walls. You can't get there with a jack. Here old Archimedes will help us. You will have to lift the beams manually, using a lever with an increased arm. When the remaining beams are already raised by this point, the task will not be so difficult. You may also want to raise the height of the window openings. To do this, you will need to raise the lintels above them and fill in the voids while the roof is on jacks. But it’s better not to be tricky with the windows, but to build brick pillars-supports on the mortar under the beams on the walls. Once it is up, the jacks can be loosened by carefully lowering the beams onto the new supports. All that remains is to bring the wall up to the level of the beams, cover up all the cracks, and walk in the renovated house in full height, and even jump for joy.

One caveat. Do not leave the jacks under load for a long time, and especially not overnight. They may fail, and if you rented them, you will also have to explain things to the owner. If you did not have time to finish the work by evening, lower the beams onto the spacers and let the jacks rest. Do not rest the jacks against the beam itself without spacers. The force is quite large, and the roof weighs quite a bit, so the beam is easy to split or split, since it is also aged. Take your time and do the work carefully. Then the house will serve you for a long time long years. Good luck!

Previously, when building a private house, they first of all thought about the possibility of quick heating in winter time. It is clear that buildings with small height rooms are heated faster and more economically. But over time, the preferences of the owners change and low rooms begin to annoy, so home owners are thinking about how to raise the ceiling in a private house.

There are several ways to expand space, from dramatic changes in the design of the building to the use of design methods visual increase room height.

Ways to raise the ceiling in a wooden house

There are several ways to raise the ceiling in a wooden house:

Lowering the floor level. This method is only suitable for buildings that are built on solid high foundation. Otherwise, attempts to lower the floor will lead to deformation of the entire structure.
If the house has suspended or false ceilings, then changing the finishing method ceiling surface will allow you to add from 10 to 15 cm to the height of the room. This method is considered the most popular.
If the ceiling beams are not load-bearing elements of the roof structure, then they can be replaced with less massive products. This will expand the space in the room.
Another way to make the ceiling higher in a wooden house is to raise the entire structure. This is done with solid monolithic structures.
If you raise the roof of the building, the height of the rooms will increase. This method is quite complex in terms of execution.

Ceiling raising technology

Before increasing the ceiling height in a private home, understand the reasons for its lowering. This will help you decide on a way to solve the problem. Cardinal methods are used if mistakes were made at the design stage of the structure. In the case of improper load distribution and natural shrinkage of the house, you should be very careful so as not to cause distortion and cracking of the walls of the structure.

The easiest way to solve the problem is if you make the wrong choice finishing materials used inside the home.

Preparatory stage

Before increasing the ceiling height in a wooden house, it is worth inspecting the roof and walls of the building. It is important to identify warped and rotted logs that could cause the ceiling to lower. It is equally important to assess the condition of the foundation, because its subsidence can also cause the house to settle. In addition, the choice of method to solve the problem depends on the condition of the foundation.

If you decide to make the ceiling higher, then you need to study design features home and technical documentation. This way you can eliminate the risk of skewing door and window openings, and also choose a way to raise the ceiling. Be sure to check it out attic space, evaluate the strength of the roof fixation and the purpose of the ceiling beams (load-bearing or not).

Lowering the floor level

You can raise the ceiling in an old wooden house to a height of 200-250 mm by lowering the floor level. But this is allowed to be done only if there is a high, solid foundation. Before starting work, remove all furniture and appliances from the house.

After this, follow the following sequence of work:

dismantle flooring using a crowbar and a nail puller;
remove old joists using a saw or hacksaw;

Important! Please note that some joists may extend beyond the boundaries of one room, so remove them carefully.

holes in the wall that remain after dismantling the joists are sealed with mortar;
new recesses are made in the walls for joists lower than the previous ones by 200-250 mm;
We insert new logs into the resulting holes;
if necessary, we insulate the wooden floor by placing insulation between the joists (we use mineral wool for insulation);
laying the subfloor and finishing flooring.

Changing the method of covering the ceiling

To make a room taller false ceiling, it is enough to dismantle the old covering and install a new covering without load-bearing frame just above the beams. This simplest way to expand space is implemented in this order:

Dismantling old finishing from the ceiling surface. We also disassemble the sheathing.
We examine the ceiling beams. If there are rotten or damaged elements, we replace them with new ones. We treat beams in good condition with antiseptics.
Sew up the space between the beams wooden clapboard or other finishing material. Eventually beam structures will protrude from the ceiling surface. They are decorated by painting them with paint, opening them with varnish, and impregnating them with tinting compounds. The elements are sheathed with clapboard, plasterboard or decorated with false boxes.

Important! Despite the fact that the interfloor beams remained in their old place, the cladding of the ceiling surface above the level of the load-bearing elements makes the room visually higher.

Replacing ceiling beams

If, upon inspection of the attic, it turns out that the beam interfloor system is not connected to the roof and is not load-bearing, then do it another way:

dismantle the ceiling covering;
fix the ceiling structures with ties or supports;
cut the beams on both sides near the walls;
then to truss structure We fasten the roofs at the height we need and attach a new ceiling to them.

Raising the whole house

Before starting work, you need to examine the foundation of the building and determine to what height the house can be safely raised. For the job you will need jacks with the required load capacity.

Attention! The house is allowed to be raised no more than 5 cm at a time. Lifting to a greater height is carried out in several approaches. After each such approach, supporting supports are installed under the structure, which are prepared in advance.

Several jacks are located around the perimeter of the house. To fix the position of the structure, it is allowed to use wedges. After the house is raised into the void under the walls, a concrete foundation is installed. After it has completely set, the supports and jacks are removed. Inside, a new floor is made a few centimeters lower than the old one.

Raising the roof

To determine to what height the roof of a house can be raised without causing significant damage to the entire structure, calculations are carried out. It is better to entrust them to specialists. Before raising the roof, the entire structure is reinforced around the perimeter. To do this, a connecting frame is made of wooden beams at the base of the roof.

After this, the ceiling is dismantled. Jacks are installed around the perimeter of the house and the roof is raised. The work is carried out in several approaches, because at one time it is allowed to lift the structure only 50 mm. After this, the resulting space between the walls and the roof is filled with an armored belt or additional crowns are added.

Visual ceiling lift

The answer to the question of how to visually raise the ceiling in a wooden house is needed if none of the methods listed above are suitable, or if the room is located in an apartment building.

In this case, the following methods of visual expansion of space are used:

If installed around the perimeter ceiling skirting boards, then they are painted to match the color of the walls or dismantled completely. This makes the ceiling surface appear higher.
Glossy light ceiling coverings And mirror surfaces visually expand the space. That is why, when choosing a ceiling finish, take this nuance into account.
Low pieces of furniture visually raise the ceiling, so decorate the interior in an oriental style.
If part of the ceiling surface along the perimeter is painted the same color as the walls, then the boundary between the planes will be smoothed out and it will seem that the ceiling is higher. To do this, at a short distance from the walls (15-25 cm) to the ceiling, glue masking tape, after which they paint the area from the tape to the wall with the same paint as the walls. After this, the tape is removed, and ceiling decor (fillet or plinth) is glued along the border of the color difference.

Rules for visual expansion of space

In addition to knowing how to visually increase the ceiling in a wooden house, you need to know rules for visually expanding the space of a room:

Choose wisely color scheme finishing. Light pastel colors expand the space, while dark and rich colors narrow it.
Choose a coating to match the color of other finishes, textiles and furniture. The more color spots that differ in tone and color, the more cramped the space seems.
Do not clutter the interior with small objects, things and decor. Remove anything that is rarely used out of sight.
A well-lit room seems more spacious. Do not cover the windows with thick curtains and install them in the room additional sources artificial light.
The traditional opinion is that they put in a small room small-sized furniture, wrong. Narrow high furniture up to the ceiling, a large sofa or wardrobe will make the room more spacious.
A large mirror on a closet door, a mirrored table or a wall - all this makes the room taller and wider.

When choosing wall decor, give preference not to one large picture, but to several small framed images. This will add visual volume to the room. High furniture allows you not to lose its functionality and save additional space.

The old buildings have low ceilings. If you are the owner of such a house and want to increase the height of the ceilings, you do not have to dismantle the roof - you can raise it yourself. Our master class will help you with this.

Tools and materials for work

We will need:

at least three jacks (preferably oil) with a lifting capacity of 5 tons;
the corresponding number of compression-resistant wooden beams, metal channels (optimally) or pipes of suitable length;
the corresponding number of rigid floor pads, which will redistribute the point load from the jack to the area load (thick boards, pieces of channel, etc.);
cushioning material that will be placed under beams and jacks during the process of raising the roof (cutting boards, bricks, etc.): their quantity must be calculated so that it is enough for all beams on both sides to the full height of the roof;
the material from which the walls will be raised (brick, shell rock, adobe, etc.), as well as mortars (sand, clay, cement, etc.): their quantity must be calculated depending on the length of the walls and the height, at which the roof will rise.

So, let's begin

If you do not plan to sew up the beams in the future, place cushioning material between the channel and the beam to prevent damage to the beam. Now you can try to carefully lift the beam. Monitor the relative position of the jack and the channel. If you see that a break is occurring at the point of their contact, loosen the jack and slightly move it to the inside of the break. Do not ignore this break - under increasing load during lifting, the channel can jump out of the connection, which can lead to injury. If there is no break, extend the jack rod no more than 5 centimeters and secure this position by placing a spacer between the beam and the wall. Do not loosen the jack.

Repeat the same operation with all jacks on one side of the house.

The more jacks you have, the better - you'll save time on reinstalling them.

Additional complications

The distribution gasket under the jack must be strong enough to avoid damage to the floor covering.

Fix the roof at the required height

Once the interior masonry has been laid and the roof is firmly in place, the outer masonry can be raised.

Since lifting and repairing a roof is a rather labor-intensive task, you should immediately think about updating the roof so that this issue no longer bothers you.
