Before repairing the roof on your garage, the structure from above is completely freed. Decide what type of garage roof repair is required. He can be:
- Dotted. When it is necessary to eliminate small defects scattered in different parts of the roof.
- Capital repairs. When there are many defective places on the roof, there are leaks. Or the coating is morally and physically worn out, has become old and invisible.
- Complete replacement of coverage due to an unforeseen situation.

Choice of coating material
After determining the type of repair, proceed to the choice of material for coating. There are a lot of materials for roof repair in the construction markets. The choice depends on the preference of the owner, financial capacity. The durability of the material, strength. There is no shortage of materials. Materials can be hard or soft. Most often, for garages, material with a low cost is used, but of good quality. Can choose:
- profiled flooring;
- slate - suitable for a gable roof;
- mastic - used in regions where there are temperature changes, a large amount of precipitation falls. The material is elastic;
- metal tiles;
- roofing material is a plastic, inexpensive material. It is used for flat structures;
- bikrost - an alternative to roofing felt. Has waterproofing properties. It is convenient to work with him;
- Technonicol is a type of rolled bituminous material intended for roof waterproofing. Manufactured using a special technology;
- Other materials.
Each material is good in its own way. It has both advantages and disadvantages. Before you choose something, you need to compare the quality of the materials. And know: where to start the repair work. Repairing the roof of the garage yourself is a responsible job. It takes time, modern tools, special clothes. To start work correctly means to consider all the actions one by one. Prepare for each one. It is even better to draw up a preliminary work plan, and stick to it. You can even sketch in pencil.
Advice: it is advisable to carry out roof repairs from the same material from which the roof has already been created! This is the best job!
Identification of defective places
Defective places are subject to careful inspection and removal. If any place in the coating is unreliable, it must also be removed. Hoping that slightly lagging material will hold securely is useless! Time will pass, the flaw will come to light, it will again need to be repaired. After removal, problem areas are cleaned, swept with a broom. Mark the areas where you need to work with a marker. A tape measure measures the amount of material that will be needed for the repair.
Let's assume a roof from the pro-thinned-out flooring. And something unpredictable happened to the coating. It has completely fallen into disrepair, it is required to lay the corrugated board again. In these unpredictable conditions, even the crate will have to be changed. It is made from wood. The lumberyard will provide the material, it is located nearby, or a lumber store. Then do-it-yourself repair of the garage roof with your own hands must be done together with the crate.
Work with profiled flooring during complete replacement of the coating
Profiled flooring is low. Using it, you can cover a huge coverage area using a small number of sheets. Before purchasing, it is necessary to accurately determine the brand of material elements. There are sheets with brand C in the form of trapezoids or semicircular waves. This material is used when a light load is expected on the structure.
The robust construction is covered with material with a wave from 35 mm to 44. This is the HC brand. Decking, which in addition has stiffeners, increased wave height, reaching up to 114 mm, is not intended for repair. And for the design of a full roof with large parameters. If the garage is small, will have an insignificant load, you need to choose a material with the HC brand. It is with elements of this brand that they repair the roof of the garage with their own hands.
Sequence of work execution
Some garages have a hard roof made of metal shingles or profiled decking. How to repair the garage roof of such a garage? It is easy to repair such a structure. Replacing a damaged sheet of material is easy. In rare cases, it is necessary to replace the coating on the garage completely. Sometimes repair of garage roofs is performed in this way.
If you work with metal tiles, then the fasteners are made, on the contrary, from the bottom and up. They work with self-tapping screws with rubber gaskets for restriction. It is necessary to place its elements with an overlap. To ensure fastening, locks are used, which are located at the bottom of the elements and at the top.
Working with roofing material
A popular method of repair work in the garage is performed using roofing material. This is a cheap material, it will well protect the roof from leaks. To patch holes, you need only a few pieces of roofing material. They can be cut from rolls. The prepared piece must be placed inside the flaw hole. It will be in the role of a patch, then, it must be pressed tightly to the base. From above, mastic is additionally applied to it.
You can also use resin for this. After that, the edges of the obsolete coating are folded back, the joints are sealed with patches. The size of a piece of roofing material should be approximately 15 cm or 20 more than the damaged area. Only in this case can we hope that the waterproofing of the joints will be complete. This garage roof will not leak. Sometimes defects are patched up in garages by TechnoNIKOL.
Then once again smear all places with mastic. This is not superfluous work, but on the contrary, it is mandatory. Providing high quality waterproofing for the roof. Only then can you place a layer of roofing material. Fresh sheets of roofing material on the roof - a guarantee of roof waterproofing for ten years.
Roofing material before laying should be "matured" for a day. For further work, tar is required. He will connect the outdated coating with the new one. Strongly protect joints from leaks. "Make" the resin in a tin container. First you need to melt the tar so that it acquires the consistency of thick sour cream.
Pour a fragment of the roof with the composition, lay the first panel on it. Walk on it a little. This is done to quickly set the resin. The second canvas is placed on the first one, but with an overlap of 10 cm to 12. When bubbles appear, it is necessary to make cuts on the material with a knife. And then press the canvas tightly to the base.
Attention: laying of roofing material starts from the lowest point of the roof. The first layer must dry for at least 12 hours.
Tool preparation
It should include modern types of tools that are easy to use. Almost every garage owner has:
- roulette;
- screwdriver, battery operated, or mains;
- self-tapping screws with rubber seals;
- hacksaw or scissors for metal.
This list is basic. Each type of instrument must be in good working order.
Conclusion
Do-it-yourself overhaul of the roof is real. The main thing is to observe safety precautions. Then the renovated garage will have a great view. Work on the roof requires a lot of attention, it is carried out at a height of two meters. You can't forget about it!
The roof is one of the most important components of any building.. Regardless of whether it was built on a respectable cottage or on an ordinary garage, the roof must fulfill its main function: to protect the interior from the effects of adverse environmental factors. As the roof is used, its individual elements wear out, and it becomes necessary to carry out repairs.
The most common defect is the penetration of moisture and atmospheric precipitation through the damaged coating. Doing so may damage the vehicle, cause mold and mildew to grow on the interior walls.
Repair work is best scheduled on a sunny warm day.
Varieties of garage roofs
The garage can hardly be called a large-scale building, but its roof is created and subsequently repaired mainly according to principles similar to the principles of arranging and repairing the roofs of large houses. A distinctive feature is the device on garages of roofs of two types:
- lean-to- in most cases, welded materials are used to cover it. It is also possible to use a metal profile or slate (with an appropriate slope).
- gable- with this type of roofing material is selected depending on the capabilities and taste of the developer. The same types of coatings are used, except for rolled ones, plus bituminous (soft) tiles or metal tiles.
Determining the cause of a leak
There are several criteria for determining the cause of a leak. Based on them, a more or less experienced person can understand what exactly should be repaired.
- If a leak forms during rain, this indicates a violation of the tightness at the junction points of the roofing material or the presence of damage.
- If a leak occurs regardless of weather conditions, this fact indicates the penetration of water into the insulation layer. In many cases, this leakage is the result of minor damage to the roofing or some waterproofing problem.
- If traces of leaks appear in the area of the cornices at the beginning of the spring season or during the thaw, this indicates a malfunction in the drainage system: in most cases it freezes. A leak of this nature may also indicate that leaves and other debris have entered the funnels of the drainpipes, which leads to their clogging.
Before starting repair work, the roof should be carefully inspected both from the outside and from the inside, from the attic.
With special care, it is necessary to inspect the junction points to the chimneys, other communications with access to the roofing surface, the ridge part.
After determining the causes of the leak, their size, specific location, an estimate of the repair work is drawn up.
Repair estimate
When drawing up an estimate, it is necessary to take into account all possible factors:
- the overall scope of the repair work;
- the cost of purchasing all types of materials;
- purchase or rental of the necessary equipment;
- payment for the work of builders (if necessary).
The essential components of the budget are:
- Calculation of the entire roof area.
- The presence of a drainage system and its design.
The estimate for repair work is directly dependent on the specific type of roofing (for example: the price of tiles is much higher than the price of slate). The color of the material and the manufacturer also matter.
If the truss system is damaged, the document should contain items relating to the purchase of materials for the repair of the truss system.
The volume and complexity of repair work is determined by the geometry of the slopes and their number. When making calculations, additional and component elements should be taken into account.
If major rather than partial repairs are required, the estimate should include the costs of acquiring and replacing heat and waterproofing materials, as well as carrying out work to improve the fire resistance of the entire structure.
It should also take into account the cost of transporting the necessary materials, tools and equipment to the site of restoration work.
Preparing the roof for work
First of all, it is necessary to remove the debris accumulated on the roof. Particular attention should be paid to cleaning problematic unreliable areas. In many cases, after a thorough inspection of the roof, it turns out that there is no need for a complete replacement of the roof and you can limit yourself to partial repairs.
Worn places should be cut down with an ax. In the future, they will need to be patched using new material.
The main ways to repair the garage roof are:
- repair with hot bitumen;
- repair using soft materials - in most cases rolled: roofing material, glass isol, bikrost, etc.;
- repair using hard roofing materials (slate, tiles, corrugated board).
If the roofing is soft, then small cracks, swellings, damages on the surface are prepared for subsequent repairs in the following way: the surface of the coating on the damaged area is cut crosswise, after which the edges are bent and pressed against the roof. The resulting hole is thoroughly cleaned and dried with a gas burner or building hair dryer. After that, you can start repair work.
Garage roof repair with hot bitumen
When planning a roof repair using hot bitumen, it is necessary to prepare some materials and tools in advance. You will need:
- half a bag of bitumen;
- bucket;
- stairs;
- rope;
- metal hook (to make it convenient to lift the bucket);
- bricks (for barbecue);
- gasoline and firewood;
- brush (for cleaning problem areas of the roof from dirt);
- gloves.
After the roof is completely cleaned, it is necessary to create a brazier and light a fire to heat a bucket of bitumen. When it becomes plastic enough, you can start pouring.
The bucket must be raised to the roof and start pouring hot bitumen into problem areas. In this case, you should ask him the direction with a wooden board. In a similar way, you can patch individual leaks or treat the entire surface.
Local repair
- To carry out local repairs, it is necessary to cut off pieces of roofing material, corresponding in size to the area of the resulting envelope.
- The holes made are coated with bituminous mastic. Molten resin can be used instead. It is necessary to ensure that the holes are completely filled with bitumen. Under this condition, the likelihood of leakage will be minimal.
- The cut off piece of roofing material is placed inside the envelope, like a patch, after which it is pressed tightly. From above it is necessary to additionally lay a layer of resin or mastic.
- After that, the cut edges of the old layer should be returned to their place and pressed against the adhesive surface.
- The next step is to stick another patch: in size, it should be larger than the repaired area by about 15-20 cm on each side.
For greater reliability, you can put another layer of mastic on top.

Required materials and tools
Before going to the hardware store, it is better to make a list of the necessary materials and tools in advance.
The main thing you need to stock up on is the material for waterproofing. The best option is ruberoid. This bituminous material has several advantages:
- perfectly glued;
- retains water for a long time;
- available in terms of price.
For gluing the roofing material, its thorough heating is required. This requires a propane torch. An alternative option is also possible - a blowtorch: it will cost less, but it will take much longer to heat up the roofing material due to the relative weakness of the flame.
The burner will also require a filled gas cylinder.
Other necessary tools for the work:
- ladder for climbing to the roof of the garage;
- rope (to lift tools and rolls of roofing material);
- a broom or a whisk for cleaning the roof from branches, leaves, other debris to the sticker of the roofing material;
- tape measure for accurate selection of material sizes;
- a mounting or shoe knife for cutting roofing felt (in this case, for convenience, a metal ruler or other object can be applied along the cut line);
- resin or bitumen for greasing joints.
The process of gluing roofing material
When repairing a roof with a roofing material, certain rules must be followed.
- The waterproofing material must be completely and deeply heated with a burner. It's not worth saving on fuel. With special care, it is necessary to warm up the corners: if this rule is not observed, they peel off over time or do not stick at all from the very beginning, which is fraught with the accumulation of water and moisture in non-glued parts, further freezing and leakage in the waterproofing material.
- The damaged old coating can not be removed, but left in place, however, all water and air pockets must first be eliminated, since later the new waterproofing material may peel off in these places. Gluing a new layer on top of the old one has one obvious advantage: in this case, it is possible to achieve optimal adhesion of surfaces, since the adhesion of materials that are homogeneous in composition and structure is much higher than the adhesion of concrete floor slabs and roofing material.
- In one pass, it is necessary to warm up the roofing material of such an area that it is possible to glue it in one turn of the roofing material roll.
- When handling a propane burner, safety rules must be observed, since it gives out temperatures up to about 600 degrees.
- After thoroughly warming up the material, it is unfolded with a foot for one turn, “herringbone” is smoothed in different directions (similar to smoothing wallpaper).
Bonding is done with gentle pressure on the material. Similarly, you should go along the entire length of the roof of the garage.
When working with roofing material, professional roofers adhere to the fundamental principle: an overlap of 15 cm must be observed at the joints of the material sheets along the length.
If the old waterproofing layer was partially or completely eliminated before the repair, then the concrete floor slabs must be treated with a bitumen primer before the new layer is glued in order to better perform the gluing process.
The device of a waterproofing coating near the deflectors of water inlets (if any on the roof of the garage) has some features. In these places, the waterproofing material must be laid in several layers (two or three), and in squares. This measure is necessary to strengthen these places and increase resistance to external factors.
Hard roof repair
The concept of "hard roof" includes the following materials: metal, folded, ordinary, profiled sheets, ceramic and metal tiles.
Due to the hardness and stability of the material, such roofs rarely need to be repaired.
However, this need sometimes arises.
Specific repair methods depend on the type of roofing.
If it is necessary to overhaul the seam roof, you should use a special tool - a comb bender, or a frame. With its help, adjacent sheets are fastened and folded into a fold. Currently, there are also electromechanical models.
If the holes are minor, they can be repaired by soldering with zinc coated steel patches.
In case of large damage to the seam roof, it is necessary to dismantle the defective sheets and replace them with new ones.
To increase the aesthetic and protective qualities of the coating after completion of the work, it is better to paint the roof.
Restoration of corrugated board also consists in the complete replacement of sheets or soldering patches in problem areas.
In the presence of minor holes (they are also called fistulas), they are repaired with tow soaked in heated bitumen.
After laying it, the places of damage should be filled with bituminous mastic.
With small defects, you can use minium putty.
If the holes are larger (up to 20 cm), patches of roofing felt or burlap are applied.
During the installation of patches, they must be made a few centimeters larger than the hole itself. The coating near the damaged area should be thoroughly cleaned with an iron brush, then smeared with hot bitumen.
After that, a roofing material or a piece of burlap is superimposed on the hole. Depending on the size of the damage, the patch should be applied in one or two layers.
The last step is to thoroughly coat the patch with bituminous mastic.
The coating can be seriously damaged if the garage roof has not been repaired for a long time.
In this case, the lining should be cut out of the roofing iron, and then nailed to the frame. Such a measure is necessary to prevent sagging of the patch.
If the roofing is ceramic tiles, then its repair consists in replacing the damaged tiles with new ones. When the frame is weakened (for one reason or another), it is also necessary to strengthen it.
The main defect of the roof of the metal tile garage is corrosion, as well as the penetration of rainwater at the points of attachment of the sheets to the rafters.
In this case, you can limit yourself to local repairs.
The damaged areas are cleaned, and the holes are sealed with tow impregnated with bitumen, after which the damaged areas are smeared with several layers of bituminous mastic.
In case of extensive damage, it is better to completely replace the coating or sheet of metal.
Necessary tools: jigsaw, screwdriver, measuring tape.
Since a standard garage is six meters long, and a sheet of metal is more than 1 meter, 6 sheets are required on each side.
The metal tile is mounted from the bottom up. Fastening is carried out using self-tapping screws with a rubber washer.
The first sheet is attached to the top of the roof in the middle with a self-tapping screw. Fastening is performed from the middle towards the edges.
The next sheet is overlapped (one wave will suffice). If the protective coating of the sheet is damaged, these areas are covered with paint to prevent rust.

Materials for the repair of garage roofs
On the Internet you can find various garage flat roof repair suggestions. There are various ways, a bunch of different roofing materials.

For every car enthusiast, a garage is a sacred place where you can hide from bad weather and steal a faithful “horse”, if necessary, repair or replace something. This building performs practical functions, so it is attached to the house or a free-standing rectangular box is built. To reduce the cost of time and money, simple but effective technologies and materials are used for construction. Most garage boxes are supplied with a flat or shed roof, which is easily and inexpensively waterproofed with your own hands using roofing material.
Ruberoid is a built-up roofing material that is made on the basis of roofing paper and bituminous impregnation. It is produced in the form of rolls 15 m wide, 15 m long. It is a durable, inexpensive and easily laid material that is used for roofing garages and other outbuildings. Roofing material can cover the roof of any shape and slope. To create a durable waterproofing coating, it is laid in several layers in a run-up, heated with a gas burner and glued to the slope. Two types of roofing material are used in the work:
Important! The numbers in indicate the weight of one square meter of cardboard, on the basis of which it is produced. The higher this number, the stronger and more durable the material. To cover the roof of the garage, roofing material with coarse-grained dressing is used, the tensile strength of which is 25-26 kgf.
Advantages of roofing material
Builders claim that more than 80% of garages and outbuildings in Russia are covered with roofing material. Responding to high demand, manufacturers are introducing new grades of fiberglass material with improved performance. This material remains the most practical way to isolate the roof from atmospheric precipitation, thanks to the following qualities:
- High degree of waterproofing. Roofing material perfectly protects the roof from moisture, as it contains bituminous impregnation.
- Low price. The cost of covering 1 square meter of a roof with roofing material is 200-300 rubles, which is 2 times less than the price of a roof made of corrugated board, tile or ondulin.
- Easy installation. For laying roofing material on the roof, you do not need to hire workers, due to this, the cost of building a garage is reduced.
- Versatility. Bitumen-based weldable roofing material is suitable for installation on various types of roofs with any slope angle.
Note! The disadvantage of bitumen-based roofing is the combustibility of this material. And in order to achieve reliable waterproofing, you have to lay roofing material in 2-4 layers.
Preparatory stage of work
The advantage of roofing felt is that it can be placed over old roofing or on a cleaned concrete base. In order to qualitatively cover the roof of the garage with welded material with your own hands, you must first prepare the installation site:
Note! If the old garage roofing material is in good condition and does not require dismantling, you still need to dry the roof before fusing the roofing material. To do this, the old coating is cut in several places with a sharp knife, pressing the accumulated liquid through the slots. In this state, the roof is left for 1-2 days, so that the moisture evaporates.
Installation of built-up roof
To cover the garage roof with roofing material, you need a gas burner, a sharp knife, protective gloves and skill. An experienced master will cope with such work alone, it is better to enlist the help of 1-2 helpers. The laying technology is as follows:
Subject to the do-it-yourself roofing material laying technology, the use of high-quality material and good base preparation, the deposited coating will last 20-25 years, preventing moisture from penetrating into the garage.
Video instruction
For domestic motorists, the garage is a sacred place. It not only stores and maintains the car, it also houses a warehouse for things that have no place in the house. If the roof leaks in the garage, then this is a real disaster and such a problem must be urgently addressed. Leaks occur due to damage to the roofing material. Depending on what the roof is covered with, methods for repairing its damage also differ. You can fix leaks with your own hands, you just need to know how to do it right.
Types of garage roof damage
The first sign that the roof of the garage is damaged will be the formation of moisture inside the premises. It is necessary to take adequate measures even with the appearance of minimal leaks. Dampness in the garage leads to premature wear of the car, as well as things and objects nearby.
There are several reasons as a result of which the roofing is damaged and leaks appear:
- weather;
- non-compliance with technology during installation work;
- use of low-quality materials;
- failure to perform minor maintenance of the roof;
- mechanical damage to the coating.
A feature of the garage roof is that usually its slope is made with a minimum slope, so it is more exposed to the negative effects of external factors. As a result, the following may appear on the roofing material:
- cracks and cracks;
Most often, cracks and crevices appear on the roof of the garage.
- breaks;
- swelling;
When blisters appear, voids are formed into which moisture enters.
- disruption of the coating by gusts of wind;
- impact mechanical damage.
Coatings such as slate or corrugated board are usually damaged by impact loads.
To cover the roof of the garage, both soft and hard roofing materials can be used. Depending on this, the repair technology will also differ.
Even when modern reliable materials are used to cover the garage, they naturally wear out over time, so you need to monitor the condition of the roof and carry out routine repairs in time.
Ways to fix garage roof leaks
Before proceeding with the repair, it is necessary to correctly assess the condition of the roof and the size of the damage. This will depend on the technology of restoration work.
Several types of repairs can be performed:
- Spot. It is done when minor damage to the coating appears - cracks, small holes, etc. - when their total area is not more than 10% of the entire roof surface.
- Current. If the area of damage reaches 15–20%, it is necessary to carry out repairs with a partial replacement of the coating. In places of damage to the roof, a part of the waterproofing material is removed and a new one is laid in its place.
- Capital. With a total damage area of 40-60% of the roof surface, it is necessary to carry out its complete repair. In such cases, the old coating is dismantled, and a new roofing material is laid in its place. This is the most complex and expensive type of repair, depending on the type of coating used, it can be carried out every 10-15 years or less often.
Regular preventive inspections of the roof and timely repair of minor damage are the key to a long service life of any roofing. It is enough to inspect the roof of the garage in spring and autumn, then you will be able to postpone such an unpleasant and costly procedure as a major overhaul for the longest possible time.
How to perform routine/emergency repairs depending on the type of roofing material
To carry out the current repair of roofs made of different materials, you will need a different set of tools.
To repair roll coatings, you need to prepare:
- gas burner or blowtorch;
- gas cylinder;
- construction knife;
- bituminous mastic;
- gasoline or kerosene for degreasing the surface;
- ruberoid or similar material.
To restore the damaged coating of rolled materials, it is necessary to open the place of damage. After that, it is cleaned, dried and a patch of the same material as the main coating is glued with the help of molten bitumen. The patch must be made larger than the damaged area by at least 10–15 cm.
To repair a hard roof (profiled sheet or slate) you will need:
- measuring instruments;
- metal scissors;
- Bulgarian;
- screwdriver;
- fasteners;
- slate or profiled sheet.
If serious damage is found to a sheet of hard roofing material, it must be completely replaced.. To do this, the sheet is removed, and a new one is installed in its place. To fix the slate, special nails are used, and the profiled sheet is attached using roofing screws.
Small cracks or damage can be repaired without dismantling. To do this, use a special mastic.
Roll roof repair
Over time, small pores and cracks appear in the roll coating, into which water penetrates. As a result, blisters form on the surface and the material peels off, leading to leaks.
Removing small cracks
If minor cracks appear on the surface, do not wait until the damage increases, it is better to eliminate them immediately. For this:
It is more convenient to seal a crack with cold bitumen, which is sold ready-made, since handling hot mastic requires caution and additional equipment.
Repair with patches
In order to repair minor breaks in the roll material, the following work must be done:
Restoration of tightness in places of delamination
There are situations when the roll coating is not damaged, but it peeled off and water got into the hole formed. There can be several reasons for detachment:
- violation of installation technology. The bottom layer was poorly heated, so the material stuck poorly;
- the roof screed was not primed;
- the roll coating was placed on the uncleaned surface.
Eliminate delamination like this:
Elimination of blisters
To repair blisters of a rolled coating, work is performed in the following sequence:
How to prepare mastic
In order to repair a square meter of roll roofing, you will need from 1 to 1.5 kg of mastic. It consists of a binder component and a filler. The resistance of mastic to low temperatures directly depends on the quality of the filler.
Depending on the type of roofing material, two types of mastic can be used:
- bituminous - used together with roofing material and glassine;
- tar - used only with roofing paper.
Mastic can be cold and ready to use or hot when it is cooked on site.
When using ready-made mastic, you save time and avoid the danger of getting burned.
In order to make mastic on your own, you need to use bitumen, which has a melting point of 70–90 o C. Mastic is poured into the prepared container and the filler is poured in - it should be about 10% of the total volume. The composition is boiled until it turns into a viscous monotonous mass. Limestone or asbestos can be used as a filler, and to increase rot resistance, 3% sodium fluoride or anthracene oil is added.
Repair of roll coating can be carried out at an air temperature of +5o From and above.

Metal roof repair
The main cause of a metal roof leak in a garage is corrosion, depressurization of the seams (folded roof) or mechanical damage to the coating.
Depending on the type of damage, repairs can be done in several ways.
Repair of galvanized coatings
The work is done in this order:
Restoration of painted coatings
Over time, the paint is damaged and the metal underneath begins to rust. This is the reason for the appearance of holes in it and, as a result, leaks.
Small holes in the metal coating can be repaired as follows:
For reinsurance, a piece of dense fabric, previously soaked in paint, can be placed on the damaged area. After laying such a patch, its edges must be ironed well, and then painted in the color of the roof.
The fabric is soaked in paint, after which it is applied to the damaged coating and painted over again
Removing defects in the roof with a sealant
To seal small cracks or holes in the metal coating, you can use a special water-based sealant:
overhaul technology
If the area of damage to the roof of the garage is 40-60%, then there will be no efficiency from the current repair, so you need to do a major overhaul.
Overhaul of roll coatings
The work is performed in the following sequence:
- Remove previous roofing material.
Completely remove the previous coating
- The new roll material is rewound in the other direction. This will help remove wrinkles and waves and simplify installation.
- Roll out rolls. In this state, the material should stay for 15–20 hours at an air temperature of at least +15 °C.
- First, funnels, pipes and junctions are pasted over.
- They apply mask. This can be done with a brush, roller or spatula.
Mastic can be applied with a roller, brush or spatula
- The material is laid and rolled with a heavy roller or brush. Everything must be done carefully and carefully so that swelling does not form.
Lay the roll coating and roll it with a brush or roller
- Lay the next strip. The overlap of the canvases should be 10-15 cm.

Overhaul of hard surfaces
Usually, slate or profiled sheet is used to cover the roof of the garage. Despite the fact that these materials differ from each other in their characteristics and appearance, major repairs are carried out in the same way:
- Remove attachments, if any.
- Remove sheets of slate or profiled sheets. You need to start work from the top row.
It is necessary to completely remove the old slate
- Check the condition of the crate. If damage is found, they must be repaired.
- New material is being installed. After the slate, along the existing crate, you can put profiled sheets or metal tiles.
Instead of slate, you can lay corrugated board
In order for the roof of the garage to serve for a long time, it is necessary to regularly monitor its condition.. It does not matter what kind of coating is used - rolled or hard. It is enough to follow the following recommendations:
- if there are trees nearby, it is necessary to remove dry branches so that during the fall they do not damage the roofing material;
- Moss that has appeared should be removed periodically, since in places where it grows, the material will be damaged faster. You can fight mosses and lichens both mechanically and chemically;
- repair alone is not recommended. Work is carried out at height, hot mastic is used, so with an assistant everything can be done much faster and safer;
- it is better to repair the roof in the warm season.
How to repair a garage roof in winter
Leaking garage roof gives its owner a lot of trouble, especially if it happened in winter. It is better to carry out repairs in the warm season, but if necessary, you can do it in the winter.
When repairing the garage roof in the winter, the following conditions must be met:
If a roof covered with hard materials can be repaired in the winter, then it is better to postpone the restoration of a soft roof until spring.
The use of modern building materials in extreme cases allows you to repair the roof in the winter. This can be done until the temperature drops below -15 o C. Expensive PVC membranes are used for this.
Roll materials used for repairs should be stored in a warm room and delivered to the roof in small quantities so that they are enough for a maximum of an hour of work. The sequence of work will be the same as during repairs in the summer, but it will take longer to dry the surface. To do this, it is better to use not a gas burner, but a powerful building hair dryer. It will not be possible to ideally repair the roof in winter, but you can fix the leak, and in the spring to carry out a better repair.
