The roof of the apartment is leaking what to do. Fixing roof leaks from shingles

With the onset of rainy autumn days in many cities and towns of our country, as a rule, the problem in housing and communal services is aggravated - leaking roofs.

Although the roof apartment building is part of the common property of the owners of this house, its Maintenance should be made by the service management company (MC) on account of the payments made by the tenants. In receipts for rent there is such a line of expenses: "Fee for the maintenance and repair of housing." We are talking about current repairs, that is, patching up minor damage, and not about overhaul.

If the roof is leaking, where to look for the guilty? Who to complain to in this case?

1. So, if the roof is leaking in your house and there is a flood in your apartment, the first thing to do is call the emergency service by calling the control room of your management company, HOA or housing cooperative (numbers should be indicated on the information stand at the entrance).
2. Didn't find the phone numbers of the specified services? Call the unified control room of the mayor's office.
3. After, not without the help of housing department locksmiths, the flood stops, contact the managing organization. At the same time, be sure to insist on drawing up an act that will fully and in detail describe the damage caused to the premises by the flood. This should be done carefully and scrupulously, without missing the slightest detail. Thus, the assessment of damage to the apartment will be made with the maximum degree of accuracy. Be sure to make sure that you still have one copy of the drawn up act, this will help you avoid hassle in the event that the employees of the management company have a desire to rewrite the act and reduce the amount of damage caused.
   The act should be drawn up even if the damage to the apartment seems insignificant to you. Defects may show up later when the flood marks dry. To do this, you need to write an application in two copies, one of which should remain in your hands. Advice! Photograph or film all damaged property, as well as stains and drips on the ceiling and walls. Be sure to set the shooting date and time function on the camera. Shoot preferably in the presence of commission members, and let them endorse the photos or videos. In the event of litigation, these materials can be very useful to you.
4. While employees managing organization draw up an act of the bay (they must do this no later than two days from the moment of your application), contact the appraisers to determine the amount of damage caused by the flood. By the way, checks and receipts for damaged furniture and equipment will be very helpful when assessing the damage to an apartment, since they document the value of an item.
5. After that, write a statement and carry it along with the results of the examination to the management company. Demand compensation for the damages caused within 10 days.
6. In case of refusal, file a lawsuit in court, where you continue to demand compensation from the Criminal Code for damages caused by the flood. The court will determine whether you are at fault or the management company is responsible.
   There is one more thing to consider important point: if at the general meeting the residents of the house decided that the repair of the roof was not required, but such a disaster happened, then they must solve the problem on their own.

If the roof is leaking, where can I get money for repairs?

After the leak is fixed, it's time to think about a full repair. To do this, it is necessary to determine the financing of expensive work.
First of all, it can be the funds of the owners, which they have accumulated under the item “current repairs”. You need to meet with representatives of the Management Company, determine the approximate cost of the upcoming repairs and find out if the budget of the house allows you to allocate such an amount. If there is enough money, then the residents should hold a general meeting of owners and, at the voting, instruct their Management Company to repair the roof at the expense of current repairs.
More than 2/3 of all apartment owners must vote “FOR” (voting results are calculated according to the area of ​​apartments). It is important to remember that without a solution general meeting owners, Management Company simply does not have the right to spend this money even on the necessary work.
If there is not enough money, then you can offer the Management Company to conduct necessary repairs against future payments, or introduce an additional payment for owners. Such a decision must also be recorded by the decision of the general meeting of owners.
For residents of those houses where capital repairs have not been done even once in decades, in accordance with Article 16 of the Law “On Privatization”, the municipality was obliged to put the housing in order before transferring it to the ownership of citizens. If local authorities have not fulfilled their obligations, then it is possible to seek capital repairs at the expense of budgetary funds in court. True, in this case, the process may drag on for several years - local administrations do not have enough funds to comply with all court decisions.
Expert advice: “The management company is obliged to maintain the house in accordance with the law. Therefore, if they explain to you that the apartment will be flooded until the residents collect money for major repairs, then this, to put it mildly, is slyness. A roof leak is an emergency situation, and the Criminal Code is OBLIGED to eliminate the causes of the accident within a day!”
Knowing your rights and how to act, you will definitely achieve your goal with a little patience and perseverance in this process.
Good luck!

Roofing work to eliminate leaks in the roof of the house.

The reasons that led to the occurrence roof leaks quite a lot - it could be like human factor, and the influence environment for those used for roofing materials. But one thing is clear that leak need eliminate how can faster(as they say “yesterday”) or your negligent attitude to the situation will result in a serious problem and here you can’t get off with minor repairs. For this problem need decide on the vine carry out a roof inspection, identify the cause and eliminate all possible places entry of moisture into the roof space).

Leaks in the roof may occur and in recently mounted cover if, during its installation, rough mistakes, the most problematic places at the joints of different roof planes, the so-called " valleys", even in places of contact of the roof with structural elements (adjacencies) located directly on the roof itself - these can be ventilation shafts, dormer windows, parapets, walls and much more. Roof damage are of varying degrees. In some cases, in order to eliminate leaks can do without small restorative works:

• Partial repair of damaged sections of roofing and adjunctions;
• Roof sealing liquid rubber and bituminous mastics;
• Partial disassembly of roofing(if possible, depending on the roof covering), bug fixes, adding the missing elements and mounting back saved coverage.

Factors that can lead to roof leaks:

• Defective roofing, or low-budget and poor quality;
• roof covering exhausted its operational life time and began to crumble;
• Violated rules and technologies for the installation of roofing;
• Damage resulting from mechanical impact on roofing(communications located on the roof and requiring maintenance, cleaning the roof from snow and ice in winter period, mechanical damage on the low-rise buildings adjacent to high-rise residential buildings residents who can dump large debris);
• Destruction of the roofing carpet as a result of corrosion on the metal roofs ) and moss( on soft roofs), fallen by tree seeds.

Price roofing works to fix leaks in the roof of the house:

Leak repair work, roof leaks(roofing) are different volumes and species. The cost of repairing leaks in the roof of a house depends both on the complexity of the work and on the roofing. The problem is that in most cases locate roof damage superficially it is not possible and it is necessary to disassemble, open sections of the roof in problem areas(leaks). Because of this, it will not work in some situations to calculate the exact cost of work to eliminate a leak, a leak in the roof of a house. In these cases, it is roof analysis with subsequent conclusion of the extent of damage and accurate scope of work to eliminate them. But there are also common cases when the problem is visible to the face - these are errors in the installation of the roofing and roofing elements, as well as the already destroyed coating due to the statute of limitations for its installation.

The minimum cost of ordering work to eliminate the leakage of the roof of the roof of a private house is 7,000 rubles.

1. Bulkhead incorrectly mounted roofing- the reason is that there is no natural ventilation roof space between the roof insulation (pie) and the roofing itself, when warm air accumulates under the roofing and is not blown through by natural ventilation (air, and if necessary installation of aerators), in contact with a colder roofing, it turns into water (condensate), as a result of which moisture returns back to the room, while spoiling it as a roof structure ( battens and truss system ) and insulation, and interior decoration premises.

2. Elimination of leakage of soft welded (roll) roofing of an apartment building.

Almost every owner of a private house eventually faces such a problem as a roof leak, and it doesn’t matter what materials the roof is made of, and how well the work is done, sooner or later leaks form. To avoid unexpected rain from the ceiling, maintenance and overhaul should be carried out in a timely manner. It will also be useful to regularly check the roof for mechanical damage and wear.

Often, roof leakage occurs at the most unexpected moment, when a full-fledged quality repair with a complete replacement of spent roof elements is impossible, that is, during prolonged rains (spring and autumn) and during snowmelt. To minimize the consequences of such a flood, you have to substitute basins and climb into the attic to find out the reasons for the roof leak. It is worth saying right away that easy repair, with the means at hand, can only be a temporary solution to the problem. Next heavy rain put all your efforts to waste.

If the roof does not leak very much, the owners of private houses often prefer not to pay attention to the existing problem, hoping that everything will be resolved by itself. Of course, in one hundred percent of cases, the problem does not eliminate itself, but only worsens. The sooner the repair of roof leaks is completed, the less effort and money will be spent on repairs.

If the roof is leaking, you can entrust the repair to professionals or do it yourself. In fact, there is nothing difficult in this. The main thing is to find out the nature of the leak and the reasons for its occurrence. It depends on what action needs to be taken.

Roof leaks can occur different reasons. The most frequently encountered of them include:

• displacement of fragments of the roofing. It mainly happens due to strong wind or the severity of the snow cover. As a result of the displacement, cracks form and the roof leaks. The joints of roofing elements with ventilation or chimneys are most susceptible to displacement;
• The second most common cause of roof leaks is condensation. In most cases, it is formed and accumulates due to errors during the installation of thermal insulation, waterproofing, ventilation and vapor barrier;
• Finally, don't forget about deterioration of roofing materials. First of all, this concerns wooden elements roofs that do not have special protection.

Whatever the reasons for the formation of a roof leak, it needs to be repaired. Of course, it will not be possible to carry out a major overhaul at an inopportune time, but a local one will help to wait out the time of heavy rainfall or snowmelt.

Roof repair

If the roof is leaking, then the first step is to climb onto it and localize the damaged area. If the damage is not obvious, then the task at hand can become difficult. Water can penetrate the roof in one place, and enter the house in a completely different place. For example, if there is a slight gap near the ridge, water can enter the house in the area of ​​\u200b\u200bthe shelves, that is, along the wall. This is due to the fact that at the point of penetration under the roof it will not be allowed to flow by the presence waterproofing material.

“You need to try to study the place of the leak in as much detail as possible and move from it up the slope. As a rule, the damage is located parallel to the leak, but slightly above it. The distance from the leak to the damaged area of ​​the roof directly depends on the steepness of the roof slope. The greater the angle of inclination, the further the slot or hole is located. When studying the roof, you need to pay attention to the change in the color of the structure and texture of the material. Rust, chips and cracks are an ideal guide for localizing the point of penetration of water under the roof.

Local repair of a roof from a metal tile

The question of how to eliminate a leak on the roof most often worries people whose roofs are made of metal tiles. Such roofs often leak due to the accumulation of condensate. To repair such a roof, it is necessary to eliminate the damaged sheet of metal. This can be done with a nail puller.

It is necessary to pull out nails not only from the damaged roof element, but also from neighboring sheets, which need to be lifted, but not completely removed. It is necessary to work with a nail puller as carefully as possible. This is due to the fact that there is a high probability of damage to entire sheets.

The removed element must be replaced with a new one, driving it under the waves of neighboring sheets. This job is best done by two people. When installing a new sheet, it is advisable to hit the old place with a nail. To do this, you should focus on the rows of nails that fasten other sheets.

Carrying out the replacement of a metal element that has become unusable tiled roof, in order to get rid of the leakage of the roof, you should pay attention to the integrity of the waterproofing material and the uniformity of the distribution of thermal insulation, because they most likely became the cause of the leakage. Repair of a slate roof is carried out in exactly the same way. But at the same time, it must be borne in mind that slate is a material that is even more unstable to mechanical stress than metal tiles.

Repair of a roof from a ceramic tile

Main cause of roof leaks ceramic tiles consists in damage to the roofing elements or the use of low-quality binding materials during the installation process. Fortunately, private homeowners wondering what to do if their tile roof is leaking has nothing to worry about. Its repair can be carried out as quickly as possible, because all that needs to be done is to replace one or more tiles. This is done as follows:

• the first step is to remove the damaged tiles;
• the same action is done with a fragment of roofing material located under it;
• then the rail is removed. It needs to be cut out and replaced with a new one.

The element causing the roof to leak has been dismantled. Now you should close up the existing holes, that is, make a patch of roofing material, which is overlapped, and install new tile tiles.

What if the roof leaks at the joints with the chimney or ventilation?

The situation when the roof leaks at the junction of the roof and the chimney is quite common. To fix this problem, you need to stock up on a sheet of galvanized iron or material that has a bituminous base. Work to eliminate the leakage of the roof of the house is carried out in the following order:

• the junction of the pipe and the roof is carefully sealed with bitumen around the entire perimeter;
• tin bends up to desired shape and attached to the chimney;
• then it is necessary, using bituminous mastic, to carefully seal all existing joints and cracks;
• after that you can put roofing material in place.

“Especial care must be taken with penultimate stage repairing the roof of the house, that is, sealing gaps bituminous mastic. It is necessary to achieve complete tightness, so if the situation requires it, the termination can be repeated several times.

Skate replacement

Quite often, the roof is leaking due to the fact that the wooden ridge is angry. In such a situation, a roof leak is eliminated in the following order:

• the first step is to dismantle the worn-out and worn-out ridge boards;
• after that, unnecessary nails are removed from the rafters. If the situation requires it, uneven places are cleaned;
• then a new skate is installed. It must be carefully leveled and securely nailed.

If the cause of the leak was only in the ridge, then after replacing it, the roof will no longer leak. It is worth paying attention to the fact that this is the only type of local repair that does not require repeated installation work at a more appropriate time.

Elimination of leaks in houses with a soft roof

A leak in houses with a soft roof is sealed as follows:

• first you need to remove the used layers of bitumen and roofing material, up to the cement screed;
• if necessary, it is required to repair or replace the aerators and restore the screed;
• after the obsolete elements of the roof have been removed, and the base has been restored, it is necessary to cut out and lay patches from the roofing material. They should be 15-20 centimeters larger than the existing hole in the roof;
• final stage of restoration soft roof can be considered as filling the site with liquid bitumen.

“It is worth remembering that in most cases the current roof can only be patched up on a temporary basis. As soon as possible, it is necessary to carry out a major overhaul. If this is not done, in best case the roof will not leak in the repaired area, but the leak is likely to form somewhere else. Living with a constantly leaking roof is not very comfortable, and the occurrence of such a phenomenon directly indicates that the roofing material has served its time and it is time to change it.”

Preventive measures

The best solution to any problem is to prevent it from occurring. In order not to wonder why the roof is leaking, you should periodically inspect its condition.

Repairing roofing will cost much less than dismantling all the structural elements of the attic, which will certainly become unusable if the roof leaks with enviable constancy. Complete dismantling of the truss system and roofing is equal to the cost of 30% of the construction of a new house. This is a good reason to think.

Especially carefully the roof should be checked before the onset of winter and spring. First of all, you need to pay attention to the presence of cracks, displacements, rust and breaks. If there is even the slightest suspicion of a roof leak, then it must be investigated. Otherwise, the first heavy rainfall will lead to rain from the ceiling.

A roof leak can ruin Decoration Materials, pieces of furniture, cause mold development, short circuit due to moisture on the wiring. But to identify its cause and even eliminate it is often within the power of everyone, and it will be possible not to turn to professionals.

Top Causes of a Roof Leak

The most common cause of leakage is the abundance of precipitation that seeps through the roof through its damage. But if on a flat roof it is easy to find the place where moisture enters the room, then you will have to suffer with a pitched roof, since here the damage site may not be exactly where the leak was found.

To find out the reason, you can follow the following rules:

1. if it flows during rain, then the cause should be sought at the junction of the roof with vertical structures: chimney, ventilation pipes;
2. if leaks occur during prolonged rains or snowmelt, then it is worth checking the gutters. If they are clogged with ice or leaves, then the water does not flow out in the right volume and is looking for weak spots in the roof;
3. if there is no precipitation on the street, and damp spots still form, then the insulation is to blame, which absorbed excess moisture. The cause can be sought in cracked tiles or an improperly organized apron.

How to inspect the roof?

Of course, during rain, in case of leakage, problem areas will be immediately noticeable. If you inspect the roof in dry weather, and there is an attic in the room, then pay attention to damp spots on the floor - there is a leak right above this place. During the rain, a wet place can be circled with chalk so as not to lose it later.

After that, you need to go to external examination already on the roof. Initially, we are looking for the cause at the junction of the roof with vertical surfaces. First you need to study the skate: are the sheets torn off, are there any damage to the heat-insulating layer. Protective aprons should be inspected for tightness at the joints. You also need to check the pipes and funnels so that there are no blockages in the form of old leaves, debris.

Wind can tear and break the material, so the edge of the roof also needs to be carefully inspected. Moss can form on the slopes: you need to get rid of it in time so that the roots do not expand the cracks between the roof elements. It's great if you have an infrared camera at your disposal to immediately see places with poor insulation and damage.

Damage that you can deal with yourself

Slate and tiles are cracking often due to change temperature regime outdoors, regular expansion and contraction. Naturally, with weather conditions nothing can be done, but the influence can be reduced: for this, it is recommended to knock out the rafters with boards and connect several legs together. Already formed cracks can be cleaned and treated with a cement-sand mortar with liquid glass.

Often waterproofing layer is broken at the junction of the batten laths and rafter legs. In order to restore the waterproofing layer, you can dismantle a piece of the roof at the site of damage: first, it is better to strengthen the adjacent tiles with wooden wedges, and pry the right one with a trowel. Nails are removed from the rails, and the parts that interfere with the repair are dismantled with a hacksaw. For safety, it is better to enclose a sheet of plywood. A piece of damaged waterproofing is cut out and a patch of the same solid material is applied instead, fixing it with glue. The slats are restored as follows: the remains of those that already exist are cut off at an angle, and then the missing part is accurately cut out from a separate piece of the slat, subsequently fixing it with wood glue and self-tapping screws. Do not forget to treat the slats with an antiseptic. Finally, the tiles are laid.

If you are using shingles , then you have already noticed that it tends to come off and tear under the influence of the wind. It needs to be repaired at a temperature above + 5 ° C so that it does not crack under your hands. The process of replacing a damaged tile with a new one is simple: the adjacent tile is lifted with a trowel or trowel to get the damaged element, the nails are removed from the rails, and fixed with glue new tile, nail it with new nails, and glue adjacent tiles to it.

metal tile can only leak in case of improper installation or in the places of fastening with self-tapping screws if a poor-quality gasket is installed. You can’t fix the wrong installation with your own hands, but in the second case, you need to simply replace the gaskets with more reliable ones that will not wear out after a couple of years.

The ideal time for roof repair is dry, cool weather, better in spring when some parts will not melt under high temperature.

When the roof is leaking serious problem. Finishing materials and interiors become damp and deteriorate, load-bearing structures are gradually destroyed. The air in the house becomes suffocating due to fumes, mold and fungus develop.

If water enters the wiring, a short circuit and fire may result. Repairing roof leaks in the city is the responsibility of public utilities. Owners of private country houses You have to deal with leaks on your own. Now I will tell you how to do it.

Roof leak detection

Leaks look different. The reasons may be a violation of the tightness of the coating and vice versa - excessive tightness:

• rain leaks (leaks directly during rain or immediately after it). Everything is obvious here, you just need to localize the place of damage and carry out repairs;
• snow. Appear during snowmelt. With an established drainage system, melt water should go down the pipes down to the catchment. But if ice plugs have formed in the gutters and pipes, it stagnates on the roof and looks for weak points through which it penetrates the house;

• condensate appear in dry weather. Condensate collects under the roofing, the insulation gets wet. The cause of the roof leakage is improperly arranged ventilation of the space under the roof;
• flickering leaks may appear due to microcracks in the roofing. Moisture gradually collects in the insulation, eventually appears on the ceiling. It does not depend on the season;
• Roof leakage in winter can occur due to temperature differences. Under the pressure of the snow mass and due to thaws, an ice crust forms directly on the coating. Snow is the best natural heat insulator; with a large layer thickness, heat does not escape through the roof. If, in addition, the attic is heated, the crust on the coating begins to thaw. Then the slightest breach of tightness is enough for water to enter the house.

Roofing leaks can be caused by:

• laying technology violations;
• wear and tear, end of service life;
• mechanical damage to the coating - for example, when cleaning snow;
• biological factors - moss, fungus, root system trees;
• decrease in the elasticity of the coating due to sudden temperature changes;
• on the green roof - the wrong arrangement of the layered structure of the lawn;
• on the operated roof - violation of the operating conditions (for example, exceeding the permissible loads).

Roof inspection for leaks

Even in the case of an obvious storm leak, locating the site is not always easy. The roofing cake is thick, the coating can be damaged in one place, and water enters the house in another - for example, where the underlying film has leaked.

The first step in detecting roof leaks is visual inspection attic. It is necessary to assess the condition of the floor, waterproofing, truss system. Next - an assessment of the condition of the roofing and roof structures. What to pay attention to first of all:

• if the roof is done sheet material- tightness of sheet joints. For example, the reasons for the leakage of a folded roof are most often the folds themselves: either they are made in violation of the technology, or they have worn out over time;

• on the gable roofs- valleys;
• flat roof leaks can be identified by visible swelling of the coating and cracks;

• soft roof leaks shingles- peeling, tears, swelling, mold, moss;

• on any roof, you need to check the tightness of the connections to roof structures;
• whether there are trees or areas overgrown with moss on the roof;
• drains. Can be clogged and outer pipe, and a drain funnel on a flat roof;

• checking and cleaning ventilation ducts.

After that, diagnostics of the coating over the entire area are performed.

note

AT high-rise building according to the results of the diagnosis, an act of leakage of the roof is drawn up. Demand a copy for yourself: it will come in handy in court if the housing and communal services repair services refuse to fulfill their immediate duties.

In a private house, if the coating has been laid recently, the cause of the leak is a violation of the technology during the installation of the roof. The company that carried out the installation is obliged to carry out the repair at its own expense and compensate you for the damage. If the roof has been in operation for a long time, you will have to call repairmen or fix leaks on your own.

Fixing roof leaks in private homes

What kind of repair you have - partial or major - depends on the condition of the coating.

flat roof

A flat bituminous roof is repaired locally if it is new and there is a lot of time before the expiration date. Heavily worn, swollen and cracked coating (damaged 40% or more) is re-paved entirely.

With a partial repair, the damaged piece is cut out with a margin of at least half a meter from all sides. They clean it, fill it with polymer mastic or liquid rubber, or send a patch. The patch should cover the edges of the hole.

Full repair of the built-up roof is carried out in the following order:

1. Remove the coating, break the screed, remove the thermal insulation.
2. Replace vapor barrier.
3. Check Status internal drains and funnels, clean, repair.
4. Lay down new insulation and screed.
5. Apply new coating. Usually it is put in two layers. Around the funnels, along the parapets, at the junctions to the roof structures, two layers must be required.

Laying the coating is usually done by two people. As the roll rolls out, its underside is heated with a burner, the laid strip is pressed down - rolled with a wooden gurney. Neighboring strips are laid with an overlap in the direction of lowering the roof.

O flat roof from PVC, you can say the same thing as about bituminous: when in large numbers damage to the membrane is completely changed.

In case of local repair, a patch is placed on the damage - it is welded with a jet of hot air, or (if the crack is small) its edges are fused together without a patch.

During a major overhaul, a complete or partial replacement is performed. roofing cake. A geotextile fabric is laid on top of the insulation, then the membrane is fixed with mechanical fasteners.

Metal profile coating

The reason for the leakage of a roof from a metal tile or corrugated board can be mechanical (a sheet is torn). If the damage is large, the sheet is easier to change entirely. If small:

• remove rust (if any);
• solder;
• treat with anti-corrosion primer;

• paint over with polymer paint to match the coating. The latter is done not only for the sake of aesthetics, but also to protect the seam from corrosion.

Another one possible reason- Self-tapping screws are worn and loose. It is better not to tighten them, but to replace them.

Before starting repairs, you should check the condition of the roofing cake - it may be necessary to replace the waterproofing film.

seam roof

Leaky folds are rolled again, additionally sealed with bituminous or silicone sealant.

If one of the paintings is severely torn, it is replaced. If the hole is small, put a patch. It can be fixed by soldering or self-tapping screws for metal (in the second case, the holes are treated with sealant).

Ceramic tiles

Ceramic roofing can crack due to temperature changes, due to violations of technology during installation, due to mechanical damage (for example, a bough from a tree fell onto the roof). Damaged tiles are replaced with new ones: wedges are driven under the top row from the defect, the damaged shingle is removed, a new one is laid, and the wedges are removed.

Since the tiles are connected to each other by a lock, when replacing, you need to make sure that the grooves of the tiles match - otherwise the lock will not close.

Flexible roof tiles

Since bituminous tiles are glued under the sun into a continuous carpet as they are used, it is impossible to remove them like hard tiles. A piece is cut around the damage.

• dry the base with a building hair dryer;
• smear with bitumen;
• lay a new tile;

• coat the joints with bitumen.

If the damage is very small, you can not cut it out: put a patch of tiles on top of the defect or simply cover the crack with bitumen. But if such minor defects are all over the roof, it's time to change the coating completely.

It is necessary to take into account an important feature of flexible tiles: it is absolutely hermetic and does not “breathe”. This means that leaks can appear without damage to the coating, due to the condensate that has accumulated in the insulation. In addition to leaks, a second problem appears: the deterioration of thermal insulation, since wet mineral wool loses its working qualities.

note

This happens if the installers violated the cake laying technology.

The sequence of layers should be like this (from bottom to top):

• ceiling lining;
• vapor barrier;
• rafters with laid insulation boards;
• superdiffusion membrane;
• counter beam (bars to create a ventilation gap, they are stuffed on rafter legs along);
• sparse crate;
• solid crate (plywood flooring);
• lining carpet;
• tiles.

Additionally, roof aerators can be used.

If the roof is cold (there is no insulation), hydro-vapor barrier films are not used: the lining carpet and the coating itself perform the function of waterproofing. In this case, a sparse crate is placed on top of the rafters, a solid one, carpet and tiles are placed on it.

I have listed the main ways to repair simple flat and pitched roofs. If we are talking about a complex operated roof (for example, green), it is advisable to have the original project on hand: it is easier to identify the cause of the leak and choose necessary complex measures to eliminate it.
