Do-it-yourself roofing roofing repair

In detail: do-it-yourself roofing felt repair from a real master for the site my.housecope.com.

Over time, any roof needs repair, especially if it is covered with roofing felt. As a rule, over the years, under the influence of temperature differences, this material begins to crack, various damages form on it, through which water can seep. The sooner you eliminate these defects, the longer the service life of the roof itself and the entire structure will be.

Since the repair of roofing material consists in patching holes, filling up cracks and gluing loose places, you will need the following materials and tools:

roofing material;
bitumen, mastic (mastic consumption is about 1.2 kg per 1 sq. m);
gas burner or hair dryer;
ax, roofing knife, trowel;
roller.

Examine the roof surface carefully for the presence of swelling, cracks. Also check the condition of the joints of the roofing felt strips. Pay special attention to the tightness of the roofing felt to the protruding elements of the roof.

After assessing the scale of the proposed work, clean the place to be repaired from dirt, wash and dry it.
Prepare bituminous mastic. You can buy it in the store or make it yourself. To do this, heat pieces of bitumen in a bucket or boiler over low heat, stirring occasionally and removing impurities. The temperature of the heated bitumen should not exceed 200 0 C, otherwise a fire may occur, the onset of which can be determined by bubbles and yellow smoke. In this case, the temperature must be urgently reduced. If the bitumen does catch on fire, then cover the bucket with a metal lid. Unfortunately, then such a mastic cannot be used, since it will lose all properties.
Add filler to bitumen in a 4: 1 ratiosuch as asbestos or chalk. Now, gradually stirring the contents of the bucket, pour the used oil into it. Bituminous mastic can only be used when heated.

The technology for repairing a roofing material roof will differ depending on the type and nature of the damage.

If the cracks are insignificant and the roof does not leak, then it will be enough to fill them with heated bitumen mastic. It is applied with a stiff brush or spatula and carefully leveled with a very thin layer. Small holes are putty with a specially prepared putty, consisting of bitumen mastic, sand and dry sawdust.

In order to patch more serious damage and small holes on the surface of the roofing material, do the following:

Cut a piece of roofing material to the required size taking into account the fact that it will completely cover the damaged area. It is desirable that the patch be 10 cm larger than the damaged area around the entire perimeter.
Fill in the damaged area molten bitumen mastic.
Using a trowel apply mastic to the patch thin layer.
Apply a patch, flatten with a roller and press it firmly against the roof with your foot.
Coat the edges of the patch with bitumen.

How to cover a garage roof with roofing felt - our practical guide.

And about the basic principles of roofing a roof with roofing felt is described in this article.

If the roof is punctured or swollen on the surface, proceed as follows:

Use an ax to cut the damaged area crosswise. Pry the edges of the roofing material with a roofing knife and unscrew them.
Clean and dry the base of the roof under the defective area with a gas burner or a blow dryer. For better adhesion of surfaces to each other, the roof can be greased with a primer.
Lubricate the inner sides of the folded roofing felt and the base of the roof molten bitumen or mastic.
Fold the edges into place, smooth out thoroughly with a roller and stamp firmly.
Coat the incision site with mastic or bitumen and put on it a pre-cut piece of roofing material and press firmly with your feet.
For better sealing grease a piece of roofing material around the perimeter with mastic.
If the roofing material does not lay down tightly and is slightly swollen, press it down with a heavy weight for better adhesion... After the mastic has hardened, the weight can be removed.
For a more secure fit a roofing material patch can be additionally nailed with 20 mm nails, the caps of which must also be covered with mastic.

If the joints diverge, lift the pieces of roofing material and dry very thoroughly with a gas burner or a hair dryer.
Coat the joints with a layer of heated mastic or bitumen, put the roofing material in place, stamp it down.
Coat the joint on top with bitumen or mastic.

At the end of the work, it is advisable to sprinkle the repaired area with sand, as this will prevent the area from overheating in the sun and protect the mastic from melting.

Regular roof repairs are troublesome, but a timely repaired roof will last much longer, and the repair itself will be cheaper than replacing the entire coating.

As a material for repairing the roof, a neighbor-builder advised to use linokrom or uniflex (you can use ordinary roofing material RCP or RPP).

At the same time, preliminary cutting is not necessary, it is more convenient to cut on site, cutting off excess material.

Thoroughly cleaned the roof of debris and leveled it, cutting off the resulting swelling of the old roofing material.

Since the roof is single-pitched, sloping, he laid the roofing sheet on the old covering perpendicular to the slope, starting from the bottom edge.

If the slope angle of the roof is more than 15 degrees, then the installation of the roofing roll covering must be carried out along the slope.

Unrolled the roll 3-4 meters forward to clarify the direction and size of the overlap, and rolled the material again. Then he glued the free end of the covering to the base of the roof, warming them up.

After that, gradually rolling it, I glued the strip, rubbing it in with a special roofing paddle (sold in a materials store) in order to avoid air getting under the layer. When he reached the edge, he cut the pipe and returned to the beginning. The next layers were laid with an overlap of 10-15 cm on the previous ones.

You can use a thick rag as a paddle.

In one place, part of the old coating had to be removed. This roof surface was primed with a brush with mastic from a mixture of bitumen and kerosene 1: 2 (suitable for both wood and concrete surfaces). For 1 square meter of roof I consumed 0.5-0.8 kg of mortar. The roofing material was installed by melting the mastic layers with a gas burner.

It is not recommended to walk on the roof after the completion of the work.

Linokrom and uniflex are rolled roofing and waterproofing materials consisting of a strong rotting base (polyester or fiberglass), on which a bituminous binder coating is applied on both sides.

Roofing material for roofing began to be produced more than 100 years ago, but over the years it has not lost its relevance. This material is appreciated for its availability, low cost and moisture resistance. However, roofing with roofing felt is subject to mechanical stress, therefore, it often requires repair. Therefore, homeowners regularly face the question of how to repair a roofing material roof. Since this material belongs to the "economy" class, it is impractical to involve professional roofers in the reconstruction process, it is more rational to do it on your own. In this article we will tell you why there are leaks in the roofing felt, as well as how to fix these gaps with your own hands.

Roofing material is a surfacing material based on roofing board impregnated with petroleum bitumen, with mineral dressing. For production, thick cardboard with a thickness of 200-420 g / m2 is used.More modern and technologically advanced counterparts are made of fiberglass or polyester. Waterproofness, resistance to ultraviolet light and microorganisms that cause decay and the formation of fungus, make the roofing material coating extremely reliable. The material is laid with an overlap in several layers, which provides excellent waterproofing. Installation is carried out by fusion, some types of roofing material are glued to the material with molten bitumen or special mastic. Leaks in such a coating appear for the following reasons:

Improper use. Manufacturers of roofing material do not recommend the use of this material on operated roofs, since when people are on this surface, mechanical damage may appear, leading to leaks. However, developers often ignore the manufacturers' warnings because of the cheap roofing material.
Atmospheric influences. Water falling on the roof from the roofing material is absorbed in a small amount into the roofing material, and then, when frost occurs, it crystallizes, leading to the formation of cracks.
Wind load. In regions with a high wind load, roofing material is damaged by sharp, strong gusts.
Incorrect installation. Most often, the reason for leaks of roofing felt roofs is poor-quality installation of the material, performed without observing the recommended technology. In particular, problems can be caused by non-adherence to overlaps between strips or poor preparation of the base of the blood.
Poor quality material. The second most common cause of leaks in roofs with roofing felt is the use of low-quality, cheap material.

Note! The service life of a cheaper lining roofing material, which is used for laying the inner layers of a roofing cake, is only 5 years. Roofing grades are more expensive, but they last about 7-8 years. Since the coating consists of several layers of material, the total duration without a repair period for roofs of such a structure is 10-15 years.

Each type of roofing material has its own shelf life, after which, first, small cracks and defects form in the roof covering, and then full leaks. Roofing material is laid with an overlap of 3-6 layers, which helps to extend the life of the material up to 15 years at best. The most common "diseases" of this coating are cracks, breakouts and bubbles. They eliminate these defects with their own hands in the following ways: Patch repair. When insignificant single damage forms on the roofs of their roofing material, patch repair is carried out. It consists in sealing defects with your own hands with new layers of roofing material of a small area. The difficulty of this method is that the stone chips, which are sprinkled on the top layer of roofing material, reduces adhesion, and therefore prevents adhesion. Installation of patches is inexpensive and can extend the operation of the roof for 1-2 seasons, but this will only slightly delay the overhaul. Important! According to the experience of professional roofing masters, it makes sense to repair the roofing felt without removing the old layers if the total area of damage on the roof surface does not exceed 10-15%.Roofing made of roofing material, made in the days of the USSR and meeting strict quality standards, has high reliability, but nowadays it is already serving its age. Due to the inexpensive price and ease of installation of this material, it has become a popular construction solution for overlapping country or garden houses, industrial buildings, and outbuildings. You can repair a roof made of roofing material with your own hands if you follow the following technology:

First of all, a thorough revision of the surface of the roof slope and the roof truss frame is carried out.If they are in satisfactory condition, repairs can be carried out without removing the old coating. If the rafters are damaged, the dismantling of the entire roof structure cannot be avoided.

The old roof covering is cleaned of debris, dust and dirt. To do this, use water and a brush with soft plastic bristles.

Where there are bulges on the roof surface, it is necessary to make shallow cross-shaped cuts, and then squeeze out the accumulated moisture from under the roofing material.

Next, the roof is left to dry. If the weather is dry and warm, moisture will evaporate in 2-3 days. If the weather is wet or the volume of accumulated liquid is large enough, use a construction hairdryer.

To increase the adhesion between the old and new coating, stone chips are removed from the top layer of roofing material, and then primed with bitumen mastic.

After the mastic has dried, start laying a new roofing material. The roofing material is cut into strips, and then fused or glued to the old coating with an overlap of 15-25 cm. 3-5 layers are mounted, placing them apart so that the joints between the material do not coincide.

Professional roofers point out the importance of maintaining overlaps between strips of roofing material. Roofing material after the end of installation gives a significant shrinkage, because of which the strips can simply disperse, forming cracks at the joints. The smaller the roof slope, the more the overlap is done.

Roofing material is a dense cardboard in rolls impregnated with bitumen

In addition to the options presented above, there is also an euroruberoid, which has an additional polymer layer that melts under the influence of high temperature, which makes it possible to install roofing material on the base with your own hands without the use of mastic.

Roofing material consists of several layers: the lower layer plays the role of a lining, and the upper layer is a protective one. In addition, the top layer of this material has a dressing, the size of the fractions of which determines its resistance to damage (the coarse-grained type can function normally for a long time without repair).

Roll material grades

When choosing roofing material, you should focus on its technical parameters and purpose, indicated by symbols of alphanumeric marking:

The first letter "P" is the name of the material;
The second letter "P" - lining, or "K" - roofing;
The third letter in the marking denotes the nature of the upper layer: "M" and "K" are fine-grained and coarse-grained, the letters "H" and "P" denote the scaly and dusty texture of the upper layer.

The numbers in the marking are the density value given in grams per square meter.

To find out the optimal number of layers of roofing material for reliable roof repair, you need to know its angle of inclination, the degree of load (snow load, regular movement of people on the roof) and the level of reliability of the roof (is the roof capable of withstanding the weight of several layers of roofing material and mastic). The greater the angle of inclination of the roof, the fewer layers will need to be laid to ensure good waterproofing:

Flat roofs with an angle of inclination of up to 3 degrees need 3-4 layers.
If the angle of inclination of the roof is up to 6 degrees, 3 layers are enough: roofing and two underlying layers.
When the tilt angle is between 6 and 15 degrees, two coats are sufficient.
With an inclination of more than 15 degrees, roofing felt is used extremely rarely, much more often preference is given to ondulin, slate and corrugated board.

In addition, when buying material with your own hands, be sure to take into account the overlap and spare tire for marriage during installation. The calculated amount of roofing material for repair is rounded up only.

When installing roofing material to the roof, a special cold or hot bitumen mastic is applied. The euroruberoid, in turn, does not need mastic, because it already has an adhesive layer.
At first glance, cold mastic is an ideal, easy-to-use option that you just need to mix thoroughly and now it is ready to use. However, cold mastic does not make the coating durable enough and dries for a long time, which brings developers back to the good old hot mastic.

Cold mastic is not strong enough for the roof, therefore hot mastic is used

Hot mastic is being prepared for the roofing felt installation procedure for a long time. Pieces of hard bitumen (in this form they are sold in the store) must be melted to a viscous consistency and filler added. Mastic is usually heated in barrels, buckets or special boilers with an open flame or blowtorch. The sign of the readiness of the mastic is the appearance of foam and small bubbles (this happens when it is heated to 150-200 degrees).

After boiling, the foam is removed from the mastic, a filler is added: sand, peat or fiberglass (about a quarter of the total volume), and mix thoroughly. The mastic is applied to the roof directly while hot.

Before applying the mastic, the base must be leveled and dried. In addition, earlier the installation of roofing material was done only on resin, or the repair was limited to the fact that the roof was simply filled with resin without any further covering. A roof filled with resin quickly begins to crack and leak. Pouring a new one over the old resin will further increase the moisture content of the roof.

Covering the old resin with roofing felt will give the same effect. That is why, it is important to knock down all the old resin with your own hands to the level of the screed or reinforced concrete floor. If the coating is uneven, a leveling screed can be made.

After the cleaned base is dry, mastic can be applied to it. After application, it is worth waiting for the time indicated on the bitumen package in order to allow the mastic to seize.Roofing material is not laid in wet or rainy weather, in which case it is better to postpone construction until dry days.Before starting work, you should make sure that you have all the necessary materials:

rolls of roofing material;

cold or hot mastic;

metal strip with dowels (if necessary).

The material is laid in 2 or more layers, and the roof must be covered from the lowest position, so that the upper layer of the material overlaps with the lower one. The main thing is that the joints of the upper and lower layers do not end up directly above each other after laying, otherwise water will very quickly penetrate into the seams between the rolls and the roof will need repairs again.This installation method well prevents water from penetrating into the seams between the rolls.To speed up the process, it is better to cut the sheets of roofing material with your own hands in advance. Prepare all the necessary pieces and roll them into rolls. In the process of unwinding the rolls, you need to be careful to ensure that the roofing material is laid down clearly along the intended border, and not shifted to the side. After rolling, you need to warm up the sheets of roofing material along with the mastic. It is necessary to warm up until the protective film on the roofing material turns white. After that, you can begin the process of gluing roofing material to the base and rolling with a special roller.Installation of the next layer of roofing material can be done only after the previous layer has finally adhered and cooled down.

For proper laying of roofing material on the roof, as well as for possible additional sealing of the seams, a special mastic will be required (a kind of "glue" for roofing material).It can be purchased ready-made - it is produced on a bitumen, bitumen-rubber or acrylic base, it can be hot or cold. However, the price of such materials is quite high, and many craftsmen prefer to make mastic on their own.

In principle, this is a simple process. Self-made mastic can also be cold or hot applied.

In the first case, bitumen, melted and cooled to 80 - 90 degrees, is mixed with a solvent (kerosene, gasoline) in a 1: 2 ratio. When diluting, bitumen is added to the solvent, and not vice versa. The resulting mastic (primer), hermetically sealed, will be stored for a long time in a ready-to-use form.
Another way is the production of hot mastic, right at the place of roofing. To do this, the bitumen is heated to a liquid state and a filler is added in the form of ground peat or chalk. The following proportions are recommended - for 8 kg of bitumen up to 1.5 kg of loose filler and 0.5 kg of oil processing. This mastic is used immediately after preparation.

Exists several options for the device of a soft roof... Consider, for example, a flat horizontal roof with a solid base and a wooden pitched roof.

Before covering the roof with roofing material, you need carefully prepare the base... It is thoroughly cleaned of debris, dirt and dust, possible remnants of the old roofing felt roof. In the presence of severe damage - pits, cracks, chips, the surface is repaired. The ideal option is to make a continuous new cement screed with a slope towards the place of the drain (the optimal difference is 1 cm in height per 1 m in length).
After complete solidification of the cement mortar it is recommended to prime the surface with a liquid primer - this will both simplify further work and increase the performance of the roof.
The first the backing layer is laid... Roll out of bales starts from the lowest point of the roof, across the slope. When using mastic, it is applied in an even layer of 0.8 - 1 m, the roofing material is rolled out and straightened to prevent the formation of air bubbles. Then the cycle is repeated until the entire roll (cut sheet) is secured. After installation, it is advisable to walk on the laid surface with a heavy roller.
The adjacent sheet is laid with an overlap of 100 mm. It is necessary to constantly monitor the correctness of the selected direction of the sheet in order to avoid parted seams or excessive overlap.
In a similar way, the entire backing layer is laid, after which time is given for drying and polymerization, at least 12 hours. At this time, possible errors can be eliminated - to expel the formed bubbles, to glue unreliable seams.
When laying the second layer an indent should be made half the width of the sheet so that the seams do not coincide. The work is carried out in a similar way. If this is the top layer, care must be taken to ensure the integrity of the sprinkling.
In the places where the roof surface adjoins the vertical structures, an additional layer is laid, which protects against moisture leakage under the roofing felt.

If "euro roofing material" is used for the roof, then no mastic is needed for its installation. Its inner surface has the necessary adhesive bitumen layer covered with a polymer film. With the help of a gas burner, the roofing material is heated until the film melts, then it is laid in the same way as on the mastic. It is advisable to "boil" the joints in addition, after laying, or to glue with mastic.

To cover such a roof you will need to make a high-quality crate for roofing felt... If funds permit, a continuous covering can be made of plywood, cement-bonded particleboards or OSB. If boards are used, there should be no significant gaps (more than 10 mm) between them.
Laying begins in the horizontal direction. from the lower edge of the roof (from the valley).A reasonable solution would be to use the lowest layer of glassine pre-coating - this will give the roof additional heat and vapor insulation properties. Sheets of roofing material are rolled out onto mastic and (or) fastened additionally mechanically - using nails with wide heads. The overlap of the sheets must also be at least 100 mm.
Upper layer stacked so that the seams do not overlap. After complete covering with the top layer of roofing material, it is additionally attached to the crate with vertical transverse slats or metal strips.
Special care should be taken to fixing the edges of roofing materialso they won't be blown away by the wind. This can be done by placing the edges of the bottom sheet under the cornice and nailing wooden slats or steel (aluminum) strips to the cornice boards.

Unfortunately, over time, problem areas may appear on a soft roof, especially if mistakes or negligence were made during the installation process. In places where air accumulates or on loose seams, the roofing material begins to shrink, crack, and the roof can leak. The roof must be inspected regularlyto make repairs on time.

The damaged areas are thoroughly cleaned of dirt, dust and top dusting coating. The areas of roofing material that have lost their elasticity are removed, the bubbles swollen from water or air are cut crosswise. The surface must be thoroughly cleaned and dried. Then the opened fragments are glued with mastic, and a wide patch of fresh roofing material is applied over it, completely covering the damaged area. You need to be very careful about carefully sealing its edges in order to prevent water from flowing.

Price for roofing work when laying roofing material on the roof - the value is variable, depending on the material, the number of layers, the complexity of the roof configuration, the quality of the initial state of the coating, etc.

If the owner of the house carefully thinks out all the necessary measures, carefully familiarizes himself with the technology, enlists the help of friends, then he will be quite able to carry out such work on his own.

The costs will be expressed only in the purchase of the necessary materials and tools, which will give significant savings.

Despite the fact that slate and roofing material have long been replaced by new modern roofing materials, their popularity continues to be at a fairly high level. After all, laying roofing material on the roof of a wooden house, bathhouse, shed or garage is an easy and quick process. Only two people can do it, and the price of this material captivates with its availability. It is for these reasons that the owners of small country or village houses most often lay roofing material on the roof.

In order for the roof, covered with roofing felt, to serve as long as possible, it is necessary to pay as much attention as possible to the crate of the roof itself.

Since roofing material is a flexible material, it can be damaged even by minor loads. For example, a cap of snow lying on the roof. And not so much in winter as during the spring snowmelt - on the days when the snow cap slides down the roof slope.

A roof covered with roofing felt does not imply winter cleaning with a shovel, so it will have to carry the load of the entire snow cap all winter.

For this reason, it is recommended to arrange not so much a crate of boards (as is often done with a step of 10-15 cm), but a continuous underlayment of plywood sheets, chipboard, OSB-plates or similar materials. In a word, for the correct laying of roofing material, it is necessary to exclude even the likelihood of deflection of the roofing material itself between the boards of a non-continuous sheathing.

Depending on the slope of the roof, roofing material is laid in several layers - from two to, in some cases, five.

The greater the slope of the roof of a wooden house, the fewer layers of roofing material must be laid. That is, if the slope is quite steep (30-45 o), then you can easily do with two layers - the underlying and the outer.

But if the roof surface tends to be more horizontal, then the number of layers must be increased. So for a slope of 15-20 o, you need to lay 2, and preferably 3 layers.

The technology of laying roofing material on a pitched roof can be carried out in one of three ways. But no matter which method you choose, you need to take into account that you should leave the overhangs of the roofing material sheets to the sides, in order to then overlap them on the gables and close the ends of the roof.

The first option, the most common one that can be seen on roofs most often, is the laying of roofing material sheets from top to bottom, along the roof slope. With this method, laying the sheets must begin from the pediment, which is located on the leeward side for most of the year, and consistently move to the opposite edge of the roof.

Depending on the area of the roof of a wooden house, it may well turn out that the length of each sheet will be enough to cover both sides of the roof at once.

If the length of one sheet is not enough to cover both sides of the roof at once, then each roof slope is covered separately, and an overlap of a sheet of roofing material through the ridge is arranged, by 20-30 centimeters in each direction.

The first option for laying roofing material

The second option involves laying roofing material across the roof slope, the so-called "herringbone". Laying begins from the bottom, leaving 20-30 cm in order to bend the roofing material along the edge of the roof and sew it with slats or metal tape.

Bending roofing material under the roof slope

When laying roofing material, they move from the bottom up, and the ridge of the roof is covered with one sheet of roofing material overlapping immediately on both sides of the roof.

The second option for laying roofing material

The third method implies a combined laying, That is, one method of laying roofing material is used as the underlying layer, and the second is used for the outer layer.

The third option for laying roofing material

The edges of the roofing material sheets are fixed with wooden slats or a strip of metal. The use of slats to secure the laid roofing material is not always justified, since over time the slats can begin to wear out, and as a result, in some places they simply stop pressing the roofing material to the roof. Water begins to flow into these places, the wind blows there debris, sand, dust, dry leaves from the trees. As a result, the process of decay begins, and the roofing begins to require repair.

Often wooden slats are used to lay roofing material on top of old shingles on wooden village houses. In such cases, the lath perfectly presses the roofing material to the irregularities of such a coating.

Therefore, for new houses with flat surfaces of roof slopes, metal strips are often used - steel or aluminum.

Also, the overlaps of sheets of roofing material on top of each other can be additionally coated with preheated mastics or bitumen for gluing them together.

In order to repair the leaky spots on the roof of a wooden house covered with roofing felt, you need to perform only a few simple steps.

What you need to have in stock:

Bituminous mastic, a roll of roofing material, a carpenter's knife or scissors, a stiff bristled brush, a hammer, nails and pliers.

Bubbles with water or air are cut with cross-shaped incisions, the space of the bubbles is cleaned and dried from the inside.
Areas of rotten or torn roofing material are removed with a knife to even edges in large whole areas.
The edges of the old roofing material are cleaned with a brush from debris, sand, dust. You can also treat them with gasoline.
If necessary, remove a section of metal tape and nails so that they do not fall under a new roofing material, which they can then easily tear from the inside.
A patch prepared in advance from a new roofing material is glued with an overlap to the repaired area on a heated mastic.
The edges of the patch are strongly pressed and smoothed so that no voids form in the places of gluing. Then the patch can be completely smeared again with mastic or bitumen.

Sometimes, after completing all the measures for cleaning problem areas, drying bubbles and removing slats, tapes and nails, the entire roof is simply re-closed over the old roofing material, but in this case, it is better to remove the old roofing material completely.

Garage roof repair: the use of roll and sheet materials

Motorists in our country are quite distinctive, preferring to repair their cars on their own. This approach is also practiced in relation to repair bases for auto garages, for example, painting a gate or repairing a garage roof with your own hands is very widespread for the simple reason that hiring specialists is quite expensive, and the process itself is not so complicated as to cause difficulties.

Nevertheless, there are a number of recommendations that you need to know and take into account in order to achieve the best result, because redoing the roof in a couple of years is not the best option. In our review, we will tell you what to pay special attention to when working and in what sequence to carry out all the necessary activities.

The roof of the garage is one of the most important parts of the structure that requires special attention.

The workflow can vary significantly depending on the type of design and its features, the most important factors are the following:

Important!
You should not wait until streams flow from the ceiling in the garage, as soon as you see wet spots, try to repair it as soon as possible.
This will fix the problem much easier and much faster.

You should not wait until the material collapses completely, current repairs are much simpler than overhaul

As you may have noticed above, all constructions are divided into two types, so we will consider each of them separately. After all, the list of works, depending on the type of construction, is very different.

This solution is very common in garage cooperatives due to the simplicity and quick installation process. In this way, roofs were made on most buildings erected during the Soviet era, but today this option is used quite widely. First of all, we will figure out how the roof is repaired with roofing felt, since this material is most popular due to its low cost.

Roofing material is the most common material for roofing garages

The work may differ depending on the extent of the damage, first of all, we will tell you about the option with the repair of individual sections:

First of all, the surface is cleaned of debris and dust, for this you can use either a brush or a regular broom. It is important that the roof is clean and that you can find all problem areas;
Next, you need to figure out the extent of the damage., if there are places in which the coating has become unusable or badly cracked, then they are cut out using an ax or a wide chisel and hammer. When swollen, they need to be opened as follows: a cross-shaped incision is made (this requires a strong sharp knife), after which the material is bent;

The incisions allow you to open the problem area

Next, you should inspect the damage, if necessary, dirt is also removed from them and the surface is dried. To do this, you can use a hair dryer or a gas burner. It is important that all surfaces are clean and dry;

The surface can be dried with a burner in just a few seconds

Previously, bitumen was most often used to treat all problem areas., which had to be preliminarily melted in a bucket over a fire, and then applied hot.But this option is dangerous and not very durable, therefore we strongly recommend using a special bitumen mastic, which is applied without heating and after hardening remains elastic, which significantly increases the reliability of the repair;
Apply by brush or roller, a piece of roofing material is glued to it according to the size of the damage. After that, the folded edges are also glued to the mastic and pressed well. The last step will be the installation of a patch, the size of which should be 20 centimeters larger than the damaged area; for additional reliability, the area is processed from above with the same composition.

You can simply pour some mastic onto the surface and spread it with a roller or spatula.

If you need to cover the entire surface as a whole, then the process will look like this:

First of all, you need to prepare the surface, if the condition of the old coating is very poor, then you need to completely dismantle it. After that, it is necessary to check the base for damage, all problem areas are sealed with cement mortar, it is important that a uniform slope is observed on the surface. Further measures are carried out after the solution has completely dried;

Remember to carefully level the surface so that there is no sagging on it.

Next, a part of the surface with a width slightly larger than the size of the sheets used is processed, the roofing material is gently pressed onto it. It is important to do this neatly and evenly to ensure the most reliable adhesion. The next strip is located with an overlap of at least 100 mm to protect the joint from moisture penetration;

For better adhesion, the joints can be heated with a gas burner

Important!
With a roof slope of more than 16 degrees, you will need to glue 2 layers of roofing material.
If the angle is less, then experts recommend laying at least 4 layers to ensure proper durability of the roof.

The layers of material are positioned so that they do not overlap with each other. If the material is laid across the slope, then the work is carried out from bottom to top, and if along, then there is no particular difference in the location. Each subsequent sheet can be glued 12 hours after fixing the previous one.

As for the new generation roll roofing materials, the work technology is as follows:

The base is cleaned of debris and treated with a primer, this is a special primer based on bitumen;
Next, the so-called bottom layer is taken, which is laid in the following way: the roll is unwound gradually, while the surface is gently heated with a burner. You should not be too zealous so as not to overheat the material, as it may simply melt. The surface is leveled and pressed;

The surface is heated in parts, after which the material is glued

After the first layer is glued on, the second one can be laid. Work with it is carried out in the same way, the only difference is that the upper part of the material is treated with a special dressing, which increases the strength and reliability of the roof.

This option is used when a rafter system is installed on your garage, it can be either single-slope or dual-slope.

As for the workflow, it does not differ from ordinary roofing work, first, consider the repair option:

Replacing damaged elements

If one or more sheets are damaged, and the rest are still reliable, then you can simply change all the problematic elements. To do this, you need to purchase the same roofing material as used on the roof. It is important that the size of the waves or profile is the same, otherwise the new sheets will not fit;
First of all, damaged elements are removed, if you have slate, you will have to get nails. And if corrugated board or metal, then you need to unscrew the special screws with a rubber washer;
New elements are put in the same place, they are placed under the adjacent sheets in the same way as the old ones, it is important that the structure is the same as it was originally.

When carrying out repairs, the accuracy and accuracy of the position of each element is important.

As for the complete replacement of the roof, the process is as follows:

First of all, the old material is dismantled, after which you need to carefully inspect the rafter system. If there are damaged elements, then they must be replaced, since the supporting structure must be strong;

Be sure to inspect the rafters after dismantling the roofing material.

If instead of slate you decide to use corrugated board or metal tile, then you will need to redo the crate, it should be much more reliable. In addition, it is necessary to lay a vapor-permeable windproof membrane;
As for the fastening, ordinary nails with a wide head are used for slate, they are hammered in with moderate effort. As for the fastening of metal materials, special roofing screws with rubber washers are used for them, twisting them, it is important not to apply too much force so as not to crush the seal.

If the roof is gable, then after fixing the main covering, it is necessary to fasten the ridge elements

Of course, the options for roofing systems may be different, some use bitumen shingles, some use tin, and some make a structure of glass or polycarbonate to let light through. Repair of a panoramic roof consists in replacing damaged elements and sealing them.
