The roof is leaking in the garage: 10 tips on what to do

Main causes of the problem

Insufficient slope angle. In this case, you can make an additional superstructure-frame from wood and lay a new coating on it.
Depressurization or poor sealing of joints. Here we only analyze the area with the problem, dry it and lay down new material with new seam taping.
A small number of layers of soft roofing for a specific object. If the coating is new, you can simply try to add the missing layer. If the roof has already been used for several seasons, then most likely everything will have to be redone from scratch.
Base defects. The soft frame under the roof or its breakdown causes subsidence and breakage of the covering. In this case, you can try to either strengthen the base or redo it completely.
Insufficient overlap of roll type covering. Another option is to add a new layer of coating on top. In most cases, you just need to do it again, but taking into account technology.
Physical defects of materials. This problem can be solved by replacing part of the roof or the entire covering.

Laying a new EPDM membrane

All currently existing types of roofing membranes are suitable for roof repairs. However, for a garage, a membrane labeled EPDM is considered the most acceptable. The material is absolutely indifferent to the proximity of the old membrane and bitumen coating, and is very resistant to atmospheric attacks. And another plus: it is wide, thanks to which the garage roof can be covered with a single piece without seams.

Algorithm for repairing a garage roof with EPDM installation:

We dismantle the metal parts of the roof.
We clean the roof down to its base and repair minor defects. Differences in the relief of the old coating should not exceed 0.1-0.15 cm. Such bumps and dents will be “smoothed out” by the new rubber shell. But it’s better if they don’t exist at all. If it is necessary to level the surface, fiberglass mesh or geotextile is pre-glued to the base.
We mark a strip along the perimeter with a marker or pencil, stepping back from the edge of the overhang along with the cornice strip by 10 cm.
Having been spread out on a lawn, lawn or similar area ahead of time, we lift the well-straightened covering onto the roof. We spread it in dry weather, the material should not get wet.
We place the coating in its future location.
Fold the fabric in half, covering one side with the other.
We apply an assembly adhesive on a neoprene-rubber base with a roller to the freed half of the base, if we are gluing it to concrete, cement-sand screed, brick, metal sheet, to a screed made of OSB panels or water-repellent plywood. We use water-based mounting adhesive if we are gluing the coating to a wooden base. We do not apply contact adhesive to the outlined border around the edge, because it is designed for attachment to horizontal planes.
We return the bent half of the covering to its place and smooth it with a roller. We work with the roller from the middle of the glued canvas to the periphery in order to expel the air and press the material more tightly.
We do the same with the second half of the sheet.
We bend the non-glued edge of the material and treat the very back side of the coating and the remaining free base with adhesive for vertical planes.
Glue and roll the material around the perimeter.

Finally, we install the cornice strips, elements of the drainage system and aprons into place.

If it was not possible to do without butt seams, we glue the EPDM panels together using an adhesive with a synthetic rubber base. The above compositions cannot be used to form seams of the material.

Owners of garages with communications passages through the roof and adjacent to walls or parapets will need to add additional layers of reinforcement on top of the covering. Reinforcement carpets around drainage funnels, aerators, and pipes are given a rounded shape. The size is calculated so that the edge of the reinforcement deviates from the edge of the hole by 20-25 cm. Along the abutment line, the reinforcing addition is applied in strips of self-adhesive membrane so that half of the strip is on the vertical plane and half on the horizontal.

Types of roofs

To find the right approach, you first need to decide on the design features of the roof and the type of roof. Then choosing a treatment method will be relatively simple. So:

If the roof of the garage and the house is piecemeal

Here problems often arise at the junctions and transitions. Less commonly, the cause is a mechanical defect (crack, hole). Damage due to hail, wind, etc. may also occur. It is also important to evaluate the quality of liquid drainage from the surface. If in some places a lot of snow and leaves constantly accumulate, then this is one of the most vulnerable areas of the coating as a whole. The same nuances apply to designs with additional elements: cuckoo, etc.

If the roof is pitched

Most often, in such structures, problems arise due to the lack of even a minimum angle of roof inclination. Puddles form after precipitation, water begins to seep into the room due to poor joints or loose gluing of roofing sheets.
In some cases, a leak begins after a strong wind, when part of the coating is torn off or undermined.
Another option is poor coating quality and frequent mechanical stress. For example, when a seasonal terrace is equipped on the roof, but this point was not thought through during construction. Consequently, the strength of the roof is not designed for additional permanent loads and problems arise.

If the roof is gable

In such a system, problems with physical defects will be more frequent. Something broke, cracked, was pierced by a branch, a stone, hail, etc. Another option: failure due to long service life, manufacturing defects, or improper installation. The joints are also considered weak: corners, turns, gutters, etc.

Next we will look at different roofing options.

Description and technology of installation of roofing materials

After it has been discovered that the garage roof is leaking, what to do in this case and what materials to choose is described below.

Since erecting a roof for a garage should be budget-friendly, you need to choose from inexpensive and easy-to-install roofing materials, for example:

roofing felt;
corrugated sheets;
asbestos-cement slate.

Ruberoid is an excellent waterproofing material and is also used as a finishing coating. It should be laid in 3 or more layers. Due to its minimal weight and use for all types of roofs, this coating is widely used in construction, however, rapid ignition, low fiber strength and short service life significantly reduce the quality characteristics of roofing material.

The main qualitative characteristics of corrugated sheets are lightness and simplicity of installation without additional strengthening of the roof frame. You should also take into account the slope of the slope and the depth of the wave. Very thin sheets quickly deform and break during operation and when servicing the roofing surface.

Slate is represented by asbestos-cement sheets treated with a fire-resistant composition. Due to the special structure, the material will last a very long time. The disadvantages are that the canvases are very heavy and fragile, which is reflected in the features of the rafter system and sheathing.

Tip #1. What to do with slate?

If the roof is covered with slate, then there are two possible problems:

Damaged slate sheets. To eliminate such a defect, you need to remove those parts that have cracks, holes, etc. After that, replace them with new, intact ones. If the leak was prolonged and many sheets, although intact, managed to get wet and damp, you need to remove all the “damaged” parts, dry them well and then install them back.

Important! If mold has formed on the sheets or a lot of dirt has accumulated, they must be washed before drying and installation.

In some cases, sheets are repaired using old-fashioned methods: they glue the cracks together with textile strips soaked in oil paint, and treat them with drying oil or other moisture-proofing substance. After this, the sheet is installed back. To strengthen the protective properties, you can also paint the sheets on top.

Failure of waterproofing. Once a gap is found, you need to take action based on the coverage itself. The point is this: find the reason. Eliminate dirt, mold, rotted elements and restore the integrity of the coating by patching a hole or joint and performing moisture insulation, one might say, sealing all seams.

Repair sequence

Each type of repair requires its own tools and materials. Let's see what features of repair work exist in different types of roofing materials.

Hard roof repair

Rigid roofing includes metal sheets, corrugated sheets, ceramic and metal tiles. Iron garage roof repairs are rarely carried out due to the strength and stability of the material. When it becomes necessary, the method of repair is determined depending on the coating. The main damage is usually rust and leaks.

The damaged material is removed and the structure is thoroughly inspected. In case of leakage, new waterproofing is installed. The sheathing is being replaced. The sheets are mounted overlapping. The corrugated sheet is fixed through the wave along the lower and upper edges using self-tapping screws.

The seam roof is laid using a comb bender: it is used to fasten adjacent sheets, bending them into a seam. The modern construction industry offers electromechanical tool models.

Local repair of small holes can be done by soldering zinc-coated steel patches . For larger damages, it will be necessary to dismantle the sheet with the defect and replace it with a new one. A roof covered with a layer of paint will look more impressive, and the paint will enhance its protective properties.

Repairing a garage roof with corrugated sheets can also begin by soldering the patches. For very minor holes, these patches can be replaced with tow, which is impregnated with preheated bitumen. Bitumen mastic is poured over the repaired area. For very minor damage, red lead putty is used. If the coating is severely damaged, the iron spacer should be cut out and nailed to the frame. This will prevent the patch from sagging.

When repairing the roof of a metal garage, it is a good idea to check the wooden structures of the structure. Their fire retardant coating may need to be updated. Repair work can be carried out with your own hands using tools that, as a rule, are available to every master. And an invited partner will help make the process faster, simpler and safer.

Repair of rolled soft roofing

Soft roofing includes roofing material, bikrost . Roofing felt is laid using tar or bitumen mastic, and bikrost is attached using a gas burner due to a layer of oxidized bitumen.

During routine roof repairs, it is enough to cut out several pieces of material and cover the cut out areas with them. Major repairs can be easily carried out independently, without the help of specialists. Roofing felt is especially easy to lay on a flat roof, directly on reinforced concrete slabs. A sheet of material is placed on a layer of tar, which is applied in stages as it progresses. The material is placed overlapping, overlapping each other by 10-15 cm. The bubbles that appear are opened with a knife, pressing the cuts and additionally lubricating them.

Very often, cracks occur at the junction of the garage roof with neighboring buildings. Pay special attention to these areas.

Depending on the method of fastening the roofing felt, certain tools are used:

the mechanical method requires the use of self-tapping screws or nails with slats;
when fastening with nails you need a hammer;
For self-tapping screws, choose a screwdriver.

The material is laid mainly in one layer, creating a solid canvas. In poor climatic conditions or difficult heavy use, a double layer is needed.

When laying, it is important to completely heat the waterproofing material, especially the corners: if the temperature is insufficient, they will peel off. This will subsequently lead to water accumulation and leaks.

The new layer can be glued on top of the old one, after first eliminating pockets of air and water. With this double layering, a tighter adhesion occurs.

Heat up roofing felt of a size that can be glued in one turn of the roll. When gluing, do not press too hard on the coating.

It is recommended to start the process from the highest point of the roof, gradually descending to the lower layers.

Slate roof repair

The service life of slate is influenced by many factors: impacts, microcracks, snow or water, vegetation, walking on the roof. Timely repair of a slate roof will prevent you from having to completely replace the roof for a long time. Slate roof repair is required in the following cases :

in the presence of leaks;
appearance becomes unpresentable;
microcracks appear;
lichens, moss, and vegetation develop.

Sometimes the source of roof destruction is incorrect installation, for example, excessively rigid fixation to the sheathing or incorrect choice of fasteners. Various materials are used to repair a slate roof:

bitumen sealant;
sealant tape;
cement or liquid glass;
a solution of a mixture of PVA glue, asbestos and cement;
drying oil with chalk;
liquid Nails;
polyurethane foam.

If it is not possible to make minor repairs from the side of the roof, they can be done from the inside using bitumen sealant. Foil placed on universal glue will help to seal a small hole from the inside. However, it should be remembered that this method is more of a temporary measure, because snow and rain outside make such a patch flimsy.

The slate is laid on the sheathing and a layer of roofing material, which serves as waterproofing against leaks . Each row of slate is superimposed on the previous one both during the initial construction and during further repairs. The coating is fixed using special nails with a sealing gasket.

Features of concrete roof repair work

Concrete roofs are usually a flat surface. They are economical, durable and have a long service life. For their construction, monolithic casting or reinforced concrete structures are used.

Leaks usually occur as a result of improper installation technology or as a result of excessively long use. Damage to the top layer of concrete can be easily corrected - just fill it with liquid rubber.

The repair process begins with attaching guides made of metal or wood to the garage walls. Floor elements are attached to them on each side, then boards are laid end-to-end along the outer perimeter and reinforced. Roofing felt is used as waterproofing, then insulation, for example, expanded clay, is laid. The entire structure is filled with cement screed until all voids are filled. The surface is leveled using a wooden lath.

After the solution has completely dried, the waterproofing and final layers are laid again.

Tip #2. What to do with bitumen shingles?

If the leak is small, you just need to replace the part with which problems arose. For this:

Take a nail puller and remove all damaged sheets of asphalt shingles. The device must be operated carefully so as not to damage entire elements.
Checking the lining. If there are signs of leaks in it, obvious peeling or divergence of seams, then we apply bitumen-polymer mastic to these places.
We attach a new element that matches the color and shape.
We carefully process the joints.

In extreme cases, the roof is completely replaced. Typically, drastic measures are needed when working with very old or poor-quality coatings. If a leak is discovered in just such a case, then replacing individual sections may be too tedious and time-consuming. Therefore, carefully assess the scale of work and the practicality of the chosen solution to the issue.

Technology for complete replacement of old coating

Major roof repairs are carried out in the warm season. It is recommended that restoration processes be timed to coincide with a period with minimal precipitation. Only in case of emergency situations is it permissible to carry out work in cold and rainy times with the obligatory installation of an awning over the repaired site. The amount of work on the roofs of private garages is usually small, but it is advisable to complete all operations in one day. As a last resort, on the first day of repairs, the roof waterproofing should be completely installed.

Typical sequence of work for a complete replacement of the coating:

Dismantling of tin aprons, if any, drainage elements, cornice and front metal strips.
Removing worn-out coverings and waterproofing carpet using a gripper. Its primitive replacement can be a shovel with a steel bayonet. To facilitate the removal process, the rolled coating can be chopped with an ax ahead of time.
Thorough cleaning of the base from crumbled material, removal of old roofing nails. It is not advisable to hammer in the fasteners remaining from the removed covering. Surely he is already infected with rust, and this infection will not stop there.
Thorough repair of the base for laying a soft garage roof. Sealing joints between reinforced concrete slabs with a cement-sand composition. The joints between solid flooring boards, OSB panels, flat slate or moisture-resistant plywood compounds are treated with silicone sealant and glued with fiberglass mesh.
Laying a waterproofing carpet, the construction of which uses reinforced polyethylene or a water-repellent bitumen-polymer barrier. Roofs with a steepness of more than 18º, covered with flexible tiles, are insulated along the perimeter, along the valleys and hips, and if lower - with a continuous carpet. Insulation of flat roofs under rolled materials is carried out around the perimeter. In both cases, the areas adjacent to walls, parapets, ventilation pipes, and drainage funnels are reinforced with additional strips and pieces of waterproofing.
Laying a new coating according to standard technology.
Installation of metal roof elements, aprons, coating fastening strips on vertical surfaces, aerators, funnels, if any.

Repair work can only be carried out at the temperature specified by the manufacturer of the material. You cannot work with coatings if the thermometer shows a value below its frost resistance limit. If there is an urgent need to carry out installation at sub-zero readings, the material is pre-cured in a heated room. Its adaptation temperature is from 15º to 20ºС, the holding time is at least 4 hours.

Tip #3. We quickly repair a soft roof

One of the options that occurs often, but on old buildings. Many modern types of roofing show themselves to be more practical. However, we’ll figure out what to do if problems arise with such a roof. Need to:

Remove the damaged area.
Remove all moisture, dirt, mold.
Dry well.
Coat the seams and joints of the base of the slabs or other base with mastic or other moisture-proofing substances.
Install additional means to prevent leaks (primers, etc.).
Lay out a new layer of roofing using technology. The overlap should be at least 15-20 cm.

Below is a video that shows a practical way to repair a soft roof.

If possible, look for alternatives to roofing felt. Today there are many analogues of this roofing material in construction stores. Be sure to ask a consultant to talk about the characteristics, advantages and disadvantages. The easiest way is to try looking in local stores if you want to “look and feel” what it is. Sometimes they offer various improved versions of roofing felt, fiberglass, etc.

Important! It is also important to use bitumen, mastic and other substances that are used for gluing joints correctly. There is no need to rush or try to pour/spread more - this can cause air bubbles to form. You need to follow the instructions for using a specific material or consult a specialist

Quick solution to major problems:

Bloating. We cut the area with an envelope, dry it, clean it, fill it with mastic, make a patch on top, which we also waterproof.

Cracks. Often formed due to too much tension and the use of a material that does not tolerate temperature changes or too high temperatures. To repair, we cover all the cracks and put a layer of roofing felt on top, which has the best characteristics.
Waves and slides. Formed due to improper installation. To correct the situation, you can put a layer of material on top that needs to be secured correctly. For this, additional mounting rails, etc. are used.

Loose fit. Most often found at joints with chimneys, drains, etc. It is formed due to the fact that the fillets were not made in advance. To fix it, we remove the top layer of coating, cut out the required areas on the new layer in advance and lay it according to technology.

Sealing small cracks

If during the inspection it was revealed that the cause of the leaking garage roof are small cracks that appear on the surface of the roofing material due to temperature changes, then they can be repaired with bitumen. To do this, use solid bitumen, which needs to be melted, or ready-made liquid bitumen, supplied immediately in finished form. The technology for sealing cracks is as follows:

The surface of the soft roll roofing is cleaned of debris and dust.
Using sandpaper or a grinder with a grinding disc, carefully remove the armor coating from the roofing material, which interferes with the sealing of the crack.
The surface of the roofing material is degreased using gasoline, alcohol or acetone.
The crack must be carefully filled with molten bitumen or cold bitumen mastic.
After the bitumen has dried on the surface, the procedure is repeated 1-2 more times to level the surface of the roofing.
To protect the roof surface from mechanical damage, until the mastic has dried, you can sprinkle it with quartz sand or small stone chips.

Please note that when sealing cracks it is more convenient to use cold bitumen. Hot bitumen mastic requires careful handling and quick work, while cold bitumen mastic is sold in ready-made form, so it is easier to use. To seal small cracks, 1 can of liquid roofing material is enough.

Tip #4. Who knows what to do with the tiles?

Follow the algorithm:

We find the problem area.
We remove part of the coating. It is important to take into account that ordinary tiles are laid according to a certain principle - so be careful.
We check the integrity of the insulation. Dry the area and, if necessary, update the waterproofing layer.
We put back the old tiles or new ones, taking into account color and other factors.

Typically, a garage roof is not covered with tiles. If the roof is old and you don’t want to take risks, then it’s better to immediately contact someone who has experience in this matter.

We patch the canvas using patches

There is another method of closing leaks that will help you figure out how to close the garage roof to prevent leaks - installing roofing felt patches. They are perfect for eliminating minor damage that has appeared in different places on the canvas. To make patches you will need roofing felt with flake or coarse dusting, bitumen mastic, a knife, varnish and a piece of emery.

For this method of eliminating defects, you will need to perform the following steps:

Clean the roof. The base of the slopes must be thoroughly cleaned of dust and other contaminants.
Preparation. The protective coating is removed from the restored surface, and to ensure better adhesion between the layers, they are degreased and dried.
We make patches. We take roofing material and cut patches - their size should be one and a half to two times the area of the defective area. In order for the patches to acquire an even shape, they are placed on a flat surface for 1-3 hours.
Next, bitumen is poured onto the treated area to obtain a film that will improve the adhesion of the patch.
The inner base of the roofing felt patches is heated with a gas burner, and then pressed firmly against the problem area of the roof.
Next, the upper part of the patch is opened with one or two layers of kukersol varnish or bitumen mastic to increase the waterproofing qualities of the restored area.

It is worth noting that to create patches, it is advisable to take roofing material with a density of at least 400 g/m2 with stone powder. To simplify the work, you can take material with a self-adhesive base, and they should only be performed at ambient temperatures above 5 ℃.

Tip #5. We quickly repair metal roofing

Commonly used materials for garage roofing are corrugated sheets and metal tiles. Easy to install, neat in appearance, durable - they have found many fans among construction companies and individuals.

If something went wrong with such a roof, then:

If the damage is small, we use one of the options: small tow, rubber paint, waterproofing with any other substance that is suitable. In some cases, it is suggested to cover the leak site with roofing felt from above, but this option will not be aesthetically pleasing.
If the leak is serious and the sheets seem intact, then we remove the covering in the intended location and look for problems with the waterproofing layer and eliminate them.

If we talk about seam roofing, then the quality of rolling seams most often suffers. Either there was a defect in the sheet itself and it was not possible to connect it well with the neighboring one, or they simply “didn’t press it enough.” Most often, you need to go through the old sheets again with a special tool. If this does not help, then it may be worth changing a couple of sheets that are not performing their functions.

Leak elimination options

A roll roof may tear, crack or swell during use. If the damage is small, it can be repaired with local patches. For example, the swollen area of the coating is opened, the moisture is removed by drying with a hair dryer. Next, a patch is fused to this place with an overlap of at least 20 cm. Mastic is applied over the entire junction area and seams.

Main stages of repair

The old roofing carpet and screed are completely removed.
The seams are treated with bitumen-polymer based mastic.
After the new screed has completely dried, a specialized material, a primer, is laid over the entire area of the roofing base.
Next, the roll covering is installed in three layers, with a side overlap of at least 15 cm.

Soft sheet coverings mounted on continuous type sheathing are subject to careful inspection. If the strength of the base has decreased, it has become uneven, so that the garage does not leak from the ceiling, it needs to be completely changed.

If a leak is found in a concrete roof structure that was once made at a slight slope, an additional wooden frame is installed.

The roof is leaking in my own garage, what should I do?

To ensure reliable protection against the penetration of moisture and water into the garage, it is necessary to install a reliable sealed roof using high-quality materials. But this is still not enough.

A full garage roof is necessarily reinforced from the inside with an additional layer of waterproofing. The material used is extruded foam boards and roofing felt.

Roofing felt is the most popular material when doing DIY repair work. It is used not only for soft roll coverings, but also for metal roofing structures.

Tip #6. If the problem is at the base

Often holes appear in concrete ceiling slabs or other floors. In this case, you first need to seal them in any suitable way and be sure to waterproof them.

Suitable patches are made only from hard, durable materials. Because when using soft coatings, there is a possibility of sagging over time and, as a result, a new leak.

One solution to the problem is presented in the video:

How to fill a garage roof to prevent it from leaking - video instructions

The garage is the sacred place of every important car enthusiast, where the “war horse” is stored and maintained, and a warehouse for those who do not have all their belongings at home. Although this building is not considered residential, a leaking garage roof can become a huge problem for its owner. Roof leaks occur due to damage to the surface of the roofing material. In this article we will talk about what needs to be done to protect the garage roof from leaks using affordable and easy-to-use materials.

Tip #7. What to do if you still haven’t found the reason

There are three obvious options:

First. We leave everything as it is, wait until the problem gets worse and again look for a place that needs to be fixed. A passive approach that takes time, but sooner or later gives results. It will not work if:

The leak is already big.
There are many valuable things in the room that will spoil if there is high humidity.
The garage is rarely visited.
There is no way to break out at any time and examine the object again.

Second. Radical. Replacement of the entire roof. With a competent approach and proper installation, the new coating, regardless of type, will last a long time without problems.

Third. Call a specialist. This option will require additional expenses, but in 99% of cases it will give a good result. Moreover, only this method of resolving the issue allows you to save personal time.

Tip #9. How to check the work of the master

At the very beginning it’s just visual. If, upon a quick inspection, no clumsy joints are visible, the seams are well joined and sealed, then, in theory, everything was done normally. It will be possible to check the quality of work after the rainy or snowfall season.

As a last resort, you can do something like an experiment: just hose down the roof for a while, but this is expensive, impractical and will definitely look weird.

To ensure that there are no doubts about the quality of the master’s work, you should look for him through reviews or recommendations from friends. If this is not possible, then ratings on different search resources can also help

Features of repairs in winter

In winter, it is better not to repair the garage roof with your own hands. If there is an urgent need, it is worth involving specialists. In winter, the main problems on the roof are bubbles due to roof separation and cracks. For the repair to be effective, the following conditions must be met:

the roof must be dry. To do this, install an awning and use heat guns;
It is important to use a safety rope for safety;
during snowfall and severe frosts (below -15°), no work is carried out.

When repairing a soft roof, heating of the materials and the roof base is required. All materials for repairs are stored in a warm room, delivered to the roof gradually as they are used. The repair itself must be carried out in accordance with building codes (SNiP).

High-quality roof installation will ensure long and efficient use of the building. Whatever material the roof of your building is covered with, careful care and timely repairs will keep it in working order, thereby preserving your car and equipment .

Tip #10. How often should you inspect your roof?

Many roofing materials can function without problems for 10 years or more. But inspect for clogged drains, deposits of dirt and leaves, cracks, swelling, etc. costs once a year. Preferably after winter. Firstly, in warm weather it will be easier to fix the breakdown. Secondly, at this time it is easiest to notice a leak if there has been heavy snowfall, rain, etc.

Circumstances of leaks

When the garage roof leaks, the rafter frame and wall decoration suffer from mold and mildew. Leaks appear due to imperfections on the surface of the coating, through which precipitation enters. Much more often, a garage roof is made from inexpensive or low-quality materials without the involvement of experienced roofers; therefore, a leak may result from a violation of the roof construction technology. This deficiency leads to the following damage:

Cracks. Inexpensive rolled roofing, from which the garage roof is made, under the influence of temperature changes, becomes covered with cracks where moisture seeps in.
Mechanical damage. Soft roofing is damaged by falling branches, rocks and debris on the roof surface as temperatures increase.
Disruptions of the canvas. Strong gusts of wind tear off roofing material, leaving the garage roof vulnerable to precipitation.
Fungus and mold. Harmful microflora softens the surface of the roofing material and can make it vulnerable to leaks.

Fundamentally important! Many owners of their own garages are wondering what to do to prevent leaks through the roof. It is possible to fully cope with this problem on your own without huge financial investments. The main thing is to recognize the problem in time and not put off repairs for a long time.
