Roof garage: installation technology, repair, materials and recommendations

After the completion of the construction of the garage walls, the question arises as to how to build a roof. The quality of this design will depend on the correct choice of material. Before beginning the arrangement of the roofing system, special attention should be paid to the study of technology.

Methods of work

Building a garage roof, you will act in several stages, the first of which provides the erection of the rafters system. Next, the installation of the waterproofing is carried out, the selected insulation material and the vapor barrier are covered. At the last stage it will be necessary to work with the covering material. If you do not need insulation, then the work will be much easier. However, transport storage conditions will be worse.

Preparatory work

The roof of the garage must be laid in sunny good weather. For this, it is necessary to familiarize yourself with the forecast for a few weeks in advance, since the work will be carried out for a fairly long time. To begin with, the concrete overlap must be cleaned of old material that has become unusable. When laying a new layer on the old coating you will not be able to create a flat surface. For this stage you can use an ax, a knife, and a chisel. The ax will make the notches all over the area, and after the roofing material it will be possible to tear off with a knife.

In more complex places, a chisel is used. If the roof was leaking, it would be necessary to exclude such errors. For this, small cracks are filled with liquid glass, while impressive ones should be filled with mounting foam. Before sealing the slots, the surface is treated with a brush moistened in water, then leave the substrate for a while. With the help of a knife it will be possible to cut off excess. Sometimes crevices are sealed with cement-sand mortar, special glue compounds or roofing mastic.

Recommendations of the preparatory specialist

The next step is to treat the cleaned plate with a primer. If there are protruding sections of the reinforcement, they must be treated with orthophosphoric acid. This procedure eliminates the further development of corrosion. If the stacked slab does not even have the slightest slope of 5 degrees, then this situation can be corrected with a layer of cement screed. This will allow rainwater to flow freely from the surface.

Roof waterproofing

When the roof of the garage is laid, there is no way to do without laying the waterproofing layer. To do this, you can use a euro-or common ruberoid. The first option, unlike the second one, is easier to lay down. The period of its use is longer. And before laying it will not be necessary to process the base. Euroruberoid should be heated, then you can proceed with installation. It will last approximately 25 years, which is 5 times more than the period during which a common roofing material can be used.

To ensure that the roof of the garage does not require repair during use, before laying the euro ruberoid, it is possible to treat the surface with bituminous mastic. The blowtorch will allow the bottom layer of the material to heat up before boiling. At this time, it is necessary to heat the surface on which the waterproofing will be laid. With the help of a metal hook, the roll is unfolded, folds should not form under it during this process. It is important to avoid the formation of air bubbles.

This material can be stacked in one layer. To do this is necessary, providing an overlap. Usually its width is 150 millimeters. In order to eliminate leaks, the material should go to a number of installed garages at 100 millimeters. If the repair of the garage roof is done by the method of laying the euro ruberoid, then for its heating it is most effective to use a blowtorch. However, as practice shows, a large amount of fuel is needed to operate. As an alternative solution is a gas burner. But its operation is dangerous because of the need to use a gas cylinder.

Mounting of a common ruberoid

Despite all the advantages of the above-described material, the traditional ruberoid does not lose popularity among consumers. If you want to use it as a waterproofing, then roll it before rolling it, so that they can align. If the area is not enough, then the material is rewound to the other side. Stacking, as a rule, starts from the bottom point. The base should be treated with mastic. Due to the lower plasticity of bitumen, it undergoes worse exposure to high temperatures, cracking with time. Before applying the mastic to the surface, it should be heated to 200 degrees. Then you can start installing the roofing material. At the same time, it is also important to provide a lap between the canvases, which must go to the neighboring buildings, pre-treated with mastic.

Selection of material for the roofing

The roof of the garage can be represented by different materials, but each of them has certain characteristics and provides compliance with the rules of laying. Choosing a corrugated board, you exclude the ingress of sediments into the room. The sheets are installed using self-tapping screws, which are screwed into the depth of the corrugation. At the edge of the material is strengthened along the ridge or overhang in every second fold. The service life of such a roof will be 50 years.

Choosing materials for the roof of the garage, you should pay attention to the slate coating, which is made of asbestos cement. It has a negligible weight. Before laying in sheets, it will be necessary to make holes for installing nails. The installation of the webs is done using the same technology that is used when using slate. Recently, slate loses its position in favor of corrugated board, as the latter lasts longer, easier to install and does not provide additional preparation of sheets.

Soft roof: ondulin

The soft roof of the garage is ondulin. The material makes it possible to form an almost waterproof surface, since it differs by water absorption, which tends to zero. While in a wet state, it does not absorb moisture. Ondulin is characterized by high resistance to temperature effects, it transfers heat and cold, and does not crack when temperature changes do not differ, which distinguishes it from other roofing materials. Despite the fact that it is based on organic material (most often cellulose), the material is biologically inert. It is not damaged by bacteria and fungi and is of no interest to insects. As an important advantage, which makes the installation of the roof of ondulin justified, it is a little layer.

Recommendations for work

If the roof of the garage roof is to be carried out by you from the ondulin, then for the beginning it will be necessary to do the installation of the lath. Most manufacturers advise carrying out these works at positive temperatures, which do not rise above 30 degrees. This is due to the fact that in the cold, ondulin can become brittle, and on its surface it is necessary to move. Use when attaching the material to the elements of the lath follows nails with hats of a special shape. For the top of the sheet you need about 10 nails, and the same number for the bottom. If the soft roof of the garage roof is carried out on a surface with a slope of up to 10 degrees, it is important to equip a continuous crate of moisture-proof plywood. In the presence of a slope of a more impressive steepness, the arrangement of a sparse crate from the timber can be made.

Methods of work

Ondulin does not provide for mandatory use of waterproofing. However, experts advise to lay a layer of hydro- and vapor barrier over the crate. This is especially true when the roof is an attic or a heated attic. After that, you can start laying the sheets. It is necessary to do this in a descent. The joints of the horizontal row should be opposite the whole parts of the sheets of the adjacent row. The overlap during laying will depend on the ramp. If the angle is less than 10 degrees, then the vertical overlap should be equal to 30 centimeters, as to the side overlap, it will be 2 waves. For a steeper slope, you need to reduce the width to 20 cm and 1 wave, respectively. The material is fixed in a zigzag pattern. The lower part is strengthened in each wave, then the waves should alternate, hammering the nails alternately in the upper and middle parts.

Local repair of soft roofing

Repair of the garage roof can be carried out locally. For this, it is necessary to cut pieces of roofing material from the prepared areas. The holes are smeared with bitumen, for this you can use molten resin. The cut piece as a patch is laid inside and tightly pressed. From above everything is poured with mastic or resin. Over the patch is patched, the size of which should be more than 15 centimeters from all sides. For reliability, the base is treated with newly used materials.

Cost

If you will carry out the roof of the garage roof, prices are recommended to study in advance. Perhaps you decide to entrust the matter to professionals. For example, stacking ondulin costs 800 rubles. Per square meter. As for slate, its installation will cost less - 300 rubles. Per square meter.

However, it is important to take into account that you will have to pay also for installing the lath and related materials. In the first case, the work will cost 200 rubles. Per square meter. While installing a ruberoid costs 80 rubles. Per square meter. But replacing the roof of the garage can be done by you yourself, then you will spend money only for the purchase of materials.
