Do-it-yourself garage roof

One of the stages of building a "house" for your car, or rather, the construction of the roof, often raises many questions. What to choose: a flat roof or attic, cheap slate or beautiful decking, insulate the slopes themselves or make a "warm" floor?

In this article we will describe how to make the roof of the garage on your own, consider the option of a single-sided and two-sided roof.

First, decide what kind of garage you need: a “warm” (heated) or cold box, which can only hide your car from rain and snow?

Now choose the type of roof:

• flat - for it it is necessary either to pour concrete overlap, or to mount it from factory plates (usually circular hollow-core), using special equipment (crane) for their installation;
• Shed - this is the easiest option for those who are going to make the roof of the garage;
• gable - a more complex version of the roof, which requires for its creation of certain building skills, as well as a greater consumption of materials (compared to a single-sided roof).

As an option, you can consider the device above the garage attic or a full second floor.

Depending on the type of roof, you should choose the option of its insulation:

• a flat roof is usually insulated on top of a reinforced concrete slab;
• the lean-to roof is insulated, usually by laying the insulation material between the rafters;
• a duo-pitch roof can be insulated either similarly to a single-slope, or by placing insulation in a horizontal overlap over the garage room.

Choose the right roofing material for your type of roof.

All these actions (the choice of the type of roof) should be carried out at the design stage, since depending on the chosen construction, its weight and, consequently, the load that the roof will have on the foundation (which in turn will affect the size of the foundation and its form: tape, columnar or slab base under the whole garage).

Flat roof

Run the roof of the garage, if you choose a flat roof, you can, but it is better to invite experts. First of all, it’s still impossible to put the finished slabs on your own (without the crew with the crane operator), and secondly, even pouring the concrete slab manually, you will need a certain amount of ready-made concrete (to make it at a time), formwork, reinforcement cages and, of course, assistants (who have already done something similar).

In the case of pouring a monolithic concrete slab directly on the garage, it is usually made strictly horizontal, and the slope is created later by laying insulation (for example, expanded clay).

If circular hollow core slabs are installed (or other types of slabs), then the slope can be created immediately during the installation process (after completing the front wall above the rest (the height difference should ensure a slope of at least 2 cm per 1 meter of slab length).

Single-skinned roof

The most simple and affordable option for beginners who want to make a roof over the garage is a shed roof. As a supporting structure (rafters), you can use metal or wooden beams, as well as fastened two boards.

1. The rafters are laid along the garage (the front wall must be higher than the others in order to create the slope required for the selected roofing material) and at the same time they rest on the mauerlat (wooden bar with a section of at least 10 by 10 cm). A layer of waterproofing should be laid under the mauerlat (pieces of roofing material are suitable).
2. On the top of the rafters is fixed with a construction stapler wind and moisture protective membrane.
3. Then, along the rafters (directly along them), a wooden counter-grille is mounted, on which (in the perpendicular direction) the crate is fixed (solid or with a certain step depending on the selected roofing material).
4. Laying roofing material is made in strict accordance with the technology of this process, developed by the manufacturer.
5. The next stage - the insulation of the roof - depends on the chosen option (between the rafters, or in the plane of overlap). Insulation from the inside should be protected with a vapor barrier.

Gable roof

To perform a gable roof, you need a device of a more complex version of the truss system. At the same time, if the roofing material chosen by you requires a significant slope (otherwise it will, for example, too much snow linger on the roof or rain water fall under it with a strong wind), then it is better not to perform the attic, but the attic (inside which to place the exploited room ).

The entrance to the attic floor is better to provide for an external staircase made of non-combustible materials.

Soft roof repair

To perform repair work on the soft roof of the garage you will need the following set of tools:

• knife;
• broom;
• ruberoid
• bitumen mastic;
• tin bucket;
• gas bottle and burner;
• building hair dryer;
• ax.

Before repair, it is worth considering the nature of the roof. In most cases, garages are in one row. And if you decide to carry out a complete repair of the roof, then you will need to contact the neighbors and agree with them about it. Otherwise, it is unlikely that anyone will like it to destroy part of its roof.

Repairing a solid roof is only necessary in dry and warm weather.

From the surface of the roof remove all foliage and other pollution. After that, inspect the roof again and decide how exactly to repair the roof - full or partial. If the roof is more than 10 years old, then it may already have cracks, bulges, and the seams simply split. Having found the problem area, you should not hurry to shoot everything. Cut it crosswise and press this area tightly. If there are cracks, then the ax can be cut through in these places. Next, you need to clean these places from dust and debris. For this you can use a hairdryer and gas burner.

How to cover the roofing with ruberoid

One of the easiest ways to repair the roof of a garage is to cover it with roofing felt. The main advantage of this material is low price. Moreover, it is an excellent waterproofing material that protects the roof of the garage from its leakage. The holes made earlier can be covered just with ruberoid. For partial repair, the roofing material can be cut into small pieces. Put this segment on the hole and press it. Top it with a coat of mastic or resin. After that, the bent old roofing felt can be pressed again and covered with mastic as well.

Cut a piece of roofing material should be more than 20 cm of the damaged area. This will provide high-quality waterproofing.

After that, you can leave everything as it is or pave a new layer of roofing material across the entire roof surface.

Flatbed ruberoid

If you decide to cover the roof with a new layer of roofing material, then it should be spread out to the surface and allowed to rest for 24 hours. To carry out the work, you will need a resin to combine the old coating of roofing material with a new one. It also protects all joints from leaking. Preparation of the resin is carried out in a tin bucket or in another container, which is subject to disposal after the work. To do this, melt torch tar to the consistency of thick cream.

When the resin is ready, fill in part of the roof, and on top of it lay a roofing felt. After that, gently walk on its surface. The next sheet is put with overlap in the direction of the slope by 12 cm, therefore it is recommended to start laying the first sheet from the bottom point.

If in the process of the roofing of the ruberoid bubbles form, it is enough to pierce a small hole and press this area tightly. If necessary, this place can be poured resin.

The first layer of roofing material should dry. 12 hours is enough for this. Next, you can install the second layer. At the same time, make sure that the joints of the first and second layers do not coincide. This will completely eliminate the possibility of moisture penetrating the layers of the soft roof.

If there are places where the roof is adjacent to the wall, then this place should be given special attention. Here, perhaps, it is important to use a sheet of tin. Most likely, in the corner you will need to make several layers of roofing material. At the same time, each layer must dry thoroughly.

If the angle of the slope of the roof of the garage is less than 15 °, then at least 4 layers of roofing material will be required. If the slope of the slope is greater than 16 °, then not less than 2 layers.

Waterproofing

There is another technology for making waterproofing the roof of the garage. For this it is not necessary to use roofing felt. A fused material known as bikrost may be used. This waterproofing material is ideal for repairing a soft roof.

The process of its application is as follows:

• Pre-roofing is cleaned and primed.
• Next, roll out a roll of bikrost as needed. Do not immediately roll a roll of material along the entire roof.
• Given the fact that the bottom layer of bikrost is oxidized bitumen, it can be heated with a burner.
• In the process of warming up, make sure that the corners and edges of the material fit tightly to the surface of the roof.
• As the material heats up, press it against the roof. Accordingly, the roll will gradually unwind.
• Each regular sheet of material overlaps up to 70 mm.
• The work process should not be delayed. Everything must be done quickly and efficiently. This results from the fact that bitumen quickly enough seizes. Tearing it off the roof may damage the material.

As you can see, the process of waterproofing a garage roof with bikrost is practically no different from laying roofing material. The only advantage is that you will not need to prepare the resin. Believe me, this is an unpleasant and painstaking process. However, the result will be no worse.

Repair hard roof

If no resin was used to cover your garage, but, for example, decking, the nature of its repair will be different. In most cases, it is likely that it will be sufficient to replace the damaged coating sheets. Although there are times when a tree has fallen on the roof. In this case, the repair will be major, including the process of manufacturing crates for flooring.

If, however, it is necessary to carry out repairs partially, then first of all you dismantle the old sheet and attach a new one. It is very important that it coincides in the wave. It is also important to ensure that the overlap is correct. Screwed sheet special screws for corrugated.

If the length of the garage is 6 m, and a sheet of material is 1 m, then the entire roof will require 12 sheets of corrugated flooring for the entire roof.

If the coating of metal, the process of repair is almost identical. The only thing that is important to control is the locks that connect the tiles.

Following such recommendations, you will be able to repair the roof. This will significantly reduce costs than would have to build it again. And with all this, always remember, very often the coating needs partial repair, and this is a significant savings. But most importantly, you can do all the work yourself.
