In many cases, the roof leaks after heavy snowfall, spring thaws, or heavy rain. This also happens due to unfair work or poor quality material. Over time, it loses its properties and wears out, but even if the roof is in excellent condition, water tends to seep through the waterproofing layers and completely invisible cracks, and then get into the home.

What to do if the roof is leaking in the house, you can learn from this article. To do this, you need to consider all possible options and choose the most optimal solution Problems.

The main reasons for a roof leak in a private house

• The roof is collapsing. This occurs when the old putty dries up and begins to crumble, the roofing material is damaged, the canvas rusts, the ridge or wooden parts decay. For example, ceramics are susceptible to cracks, and metal tiles are susceptible to the rapid appearance of rust;

• Low quality roofing materials;
• Often a small slope provokes a roof leak in a private house, because with small flaws in the roofing, water immediately gets under it;
• The displacement of the elements of the roofing material, from which the cracks are formed. In this case, the canvas does not coincide with the slope of the roof, and usually places with ventilation pipes and a chimney, at the joints of the roofing "carpet" are subject to this;
• Material wear. The reason may be temperature drops, precipitation, Sun rays, Hurricane. Due to these factors, roof leakage will increase every day. This does not depend on what the materials are made of and how long they will last;

• Incorrect installation - the development of the project was carried out incorrectly;
• Violation of construction technology. For example, improperly laid roofing material, the use of poor fasteners.

How to repair a roof in a private house

First of all, find where the roof is leaking. Explore first attic and take a good look at the surface of the roofing "carpet". Roof leaks can occur well above the area where moisture has entered the attic, so water can seep into the dwelling in a completely different place from the leak.

Once the source of the roof leak has been identified, the homeowner should consider repairing the roof, and great importance will have the material from which the roof is made.

• A slate roof can leak due to chips and cracks in the sheets. In this case, they will need to be independently changed to new sheets or covered with a cement solution (cement and sand - 1: 2). And with a small crack, you can take a simple sealant for working on the street or a special tape on a bitumen basis;

• If a tiled roof has leaked, then this may be due to damage to the tiles and their displacement from their place. In this case, the damaged tile must be replaced with a new one, and the roof must be additionally fixed. The roofing “carpet” can also leak from the cement holding the plates together if it crumbles. Then, instead of him, they prepare a solution of lime and a small amount of tow, and sand (1: 2) with their own hands. This mixture is used to cover the cracks in the tile plates. A place with a crack can be smeared with bitumen-based mastic on all sides;
• A metal roof is the most reliable, although it can also leak. In this case, you just need to replace a few elements, but you need to wait until the roof is completely dry. We dismantle the damaged tile, cut out the slats from the wood that are under the tile. We take a piece of roofing material and cut off a part equal to the area of ​​damage. We attach it, put new strips on which we impose a new sheet of metal tile;

• Repair of a roof made of iron sheets. An iron roof can leak due to the formed scratches or metal corrosion. First, scratches and dents must be cleaned from dirt with a metal brush or sandpaper and treat with red lead putty, and fill small holes with bitumen mastic. If the holes are large, then steel patches are applied to them more than the holes themselves by 10-15 cm. With the help of hot bituminous mastic the edges of the steel patches are cleaned and soldered to the edges with a soldering iron. After cooling, the excess is removed with a file and the patch is painted oil paint;

• The roof of the corrugated board is repaired by replacing the worn-out sections of the waterproofing or roofing "carpet". New rubber washers are installed on the fasteners;
• If the profiled sheet is damaged, it is replaced if the scale of the damage is large;
• A small defect in the coating can be temporarily covered with silicone - until the roof is overhauled in the near future;

• If the lesions are medium in size, they are blown out with polyurethane foam... After hardening, it is cut off with a simple knife, and the cut is covered with water-repellent paint;
• In winter, the leak can be covered only temporarily with special sealants and mastics - until the onset of heat, when it will be possible to do everything more thoroughly.

Roof leakage in an apartment building - how to solve the problem correctly

Leaks, in addition to all kinds of precipitation, are from microcracks in roll materials or from condensation accumulated under the roofing "carpet". And all this does not depend on whether it is an old house or a new building. The general reason for leakage is that the tightness of the roof covering is impaired.

Reasons for a flat roof leak:

• The shelf life of the roofing material has expired or is of poor quality;
• Damage to the roof covering, especially in winter when carrying out works related to snow removal and ice removal;
• Violation of technology for installing roofing;
• The edges of the roof are blown out by gusts of wind and rise, so snow or precipitation falls under the roof. In this case, the technology of gluing roll elements may not be followed;
• On roof covering negative impact the roots of the bushes of plants, which destroy it. This problem is often seen in the garage, where plants grow on the roof.

Reasons for a pitched roof leak:

• The leak occurs in the place where the roof is adjacent to the smoke and ventilation ducts, the walls. The place of their contact is poorly arranged, the gutters and gutters are improperly equipped;
• Temperature also greatly influences leaks.

What to do if the roof leaks in apartment building? It is impossible to repair the current roof on your own, this should be done special services... To understand where to turn to in this case with a complaint, you need to know the address management company, which is responsible for the condition of your house, and above all, take pictures of leaks in the apartment and areas with roof leaks, or make a video with the date and time. First, contact the dispatcher of the housing department, preferably with a written statement. But if this is not possible, then call by phone. Be sure to try to find out the full name of the person and his position, and the number under which your complaint will be registered.

If the roof is leaking on the balcony last floor, you can count on help from the housing department by submitting an application there. On the lower floors, you will have to repair the balcony roof yourself.

Utilities actions

To eliminate the leak, a commission must be created within two weeks, which will come to the apartment. She should draw up an inspection report, in which the cost of the repair and the amount of damage caused should be an important point. Make sure you have witnesses present.

Search for a leak

When inspecting a dwelling, the commission must establish the problematic place where the leak is coming from. This must be understood by workers who inspect the outside of the roofing part and the room from the inside. They draw up an appropriate act, which is signed by the commission and witnesses. If a "bad zone" is found, the representatives of the housing department must make a decision to eliminate the problem.

How to resolve the issue through the court

If there is no action on the part of the housing department to solve the problem, the owner of the apartment has the right to apply to the court. Be sure to indicate the reason for the appeal, the magnitude and type of the accident, the amount of damage caused. Management companies do not like such proceedings, so they will quickly begin to fulfill their direct obligations. After all, if water enters the room, it will create a threat not only to health, but can also provoke an emergency situation.

Video: A quick way to eliminate roof leaks

Often, private home owners are faced with a roof leak over time. This is not affected by either the roofing material or the quality of work. Leakage can only be prevented by timely maintenance and overhaul, as well as periodic roof checks.

Why does it flow

The leak can be quite unexpected, while carrying out renovation works can get confusing. For example, if the roof leaks during a prolonged rain for several days, or if the snow begins to melt at this time.

As a result, you have to save yourself with basins, other containers and vessels. At the same time, a quick repair of the current roof will not be an effective solution, since the next precipitation will again lead to a leak.

To solve the problem, you need to understand why the roof is leaking. With the correct determination of the reasons, you can even try to cope on your own, without resorting to the cost of the services of professionals. The roof can be leaking due to:

• the appearance of cracks in the roof - its individual parts may shift due to the effects of weather conditions, as a result of which a leak occurs at the junction;
• problems with condensate - if heat, hydro and vapor barrier, as well ventilation system were not installed correctly, moisture can accumulate and the roof will leak;
• the materials from which the roof is made can also wear out; in this regard, wood is the most susceptible to wear.

After finding out the reasons, you can start to eliminate them, independently or with the help of professionals. Let's figure out what to do if the roof is leaking.

What to do

Let's try to figure out how to fix roof leaks. Regardless of the reasons, they will have to be eliminated with the help of repair. Under favorable weather conditions, you can overhaul... However, as a rule, it is necessary to eliminate the leak quickly, for this it is carried out Maintenance... For these purposes, you need to inspect the roof and find the leak.

If it is not possible to identify it visually, then this can lead to additional problems. Examine the leak carefully and find the area that was damaged. After that, depending on its location and the type of roof, you can start working.

If the roofing material is a metal tile, then you will have to remove its damaged element with a nailer or other tool.

When doing this, be careful not to damage other metal sheets... Then, instead of the damaged sheet, you should put a new one. The repair of tiles from a different material is carried out in the same way.

If the roof leaks at the joints, then the resulting gap will have to be repaired with something. As a rule, this place is located between the roof and the chimney. The gap formed should be closed with galvanized iron, or with a bitumen-based element.

The process of eliminating a leak will include several stages.

• First, the material is applied to the joint, while covering an area much larger than the gap. In this case, the material must be given the correct shape, for example, if iron is used, then it must be bent.
• Secondly, with the help of elastic material, seal the joints and all holes, and quite carefully, so that you get an airtight surface. Otherwise, the flow will continue.

In conclusion, the roof is restored with the same material that makes up its undamaged part.

If the roof leaks due to damage to the ridge, for example, if this element of wood begins to rot, then you have to this part replace. In addition, of course, other parts that have been damaged will have to be replaced.

To do this, the damaged roof parts must be dismantled. For example, pull out the boards, which will require removing the nails from them. The next stage is cleaning from humus, rust, etc. After the place is cleared, you can install new elements.

It should be noted that after such repairs are carried out on their own, it will be necessary to periodically check these places for leaks and, if necessary, repeat all the described manipulations, or call specialists or carry out a major overhaul of the roof.

Photo of the current roof

All roof structures during operation sooner or later begin to leak. This may be due to various reasons that need to be carefully investigated so that permanent repairs are not useless or frequent. The timeliness of the repair will ensure that the rafter system, the communications carried out and all the insulating layers remain intact, and the repair will cost a minimum of costs.

The main reasons for roof leaks
If the roof is leaking, how to lay it and in what way, you can understand only after determining the reasons:
1. Natural wear and tear of the roofing material after the end of its service life. Typically, a seal failure occurs after long cycles of temperature drops, exposure to the weight of precipitation in winter period influenced by solar ultraviolet rays... The material loses its basic properties and insignificant influence of any nature can cause it to crack, peel off or fall off the roof. If, for some reason, it is not possible to eliminate such consequences in time, the penetrating moisture into the under-roof space can irreversibly damage the insulation, cause rotting of the floor beams, and also leak into the living quarters. The most vulnerable materials to natural wear and tear are: roll welded (roofing material, ceramic tiles) and soft coatings (bituminous shingles), slate, ondulin.

2. Mechanical damage. The reasons for such violations of the tightness of the roof are: the fall of adjacent structures or trees on the roof, hail or wind. Even properly designed roofs cannot withstand significant instantaneous loads, since the margin of safety for unforeseen situations is usually insufficient or, in order to save money, it is not laid. The only advantage of such factors is the visual visibility of the entire scale of destruction and, in most cases, the absence of the need to perform complex searches for cracks.

3. The use of deliberately low-quality materials in order to reduce the cost of the object or to minimize the weight of the load on the foundation of the building. Non-compliance with building codes is first created frequent breakdowns roofs under any operating conditions. In the worst case, with additional non-compliance with the laying technology, you will have to perform a complete replacement rafter system, lathing and all waterproofing layers.

4. Incorrect installation of the waterproofing layer. There is a rather complex and serious problem when an outwardly completely intact and solid roof suddenly begins to leak without minimal damage. The thing is that if the waterproofing film was not glued or overlapped, then when the temperature spreads outside the building and inside, condensation can form on its surface. It may not be visible for a long time, but the insulation based on mineral wool or expanded clay will lose its thermal insulation characteristics and the entire building will become uneconomical in terms of energy efficiency. Further, the lathing and supporting beams will begin to dampen, and only then damp spots can be noticed on the ceiling inside the premises. If you do not find and eliminate the flaws in time, the roof may collapse partially or completely, depending on its design.

5. Incorrectly selected: roofing material, lathing step, slope of slopes, section load-bearing beams, a method of fixing the rafters to the Mauerlat. The danger of such leaks lies in their unpredictable and large-scale appearance, since outside and inside the roof can have perfect view... However, the incorrect distribution of the load of all layers will manifest itself in the near future, since it depends on the built-in safety factor.

If the roof is leaking - how to find the leak?

To find the place of the leak, you need to go up to the attic and assess the condition structural elements roofs. Usually, in places of leaks, the formation of dampness, mold or even rot is observed. In this case, it is necessary to take into account the slope of the roof slopes and assess the approximate location of the problem area. Then you need to turn off the electricity, if there is wiring under the roof. It is necessary to go up to the roof and from the outside inspect the condition of the visor, the joints of the roofing material, and their attachment points. In this case, it is necessary to mark problem areas that need repair or replacement. In the case of the presence of ventilation pipes on the slopes, it is worth Special attention to give the places where the roof is connected, since in most cases there can be hidden problems in them.

Since water could completely fill the slopes of the roofs in the under-roof space in the presence of a continuous sheathing, it is necessary to inspect the visors, wind boards. If traces of moss growth were found on them, then they must be cleaned to the base material in order to be able to assess its strength. If the gutters obstruct the view, they must be temporarily dismantled. If during the inspection no leaks were found and the roof of the house is still leaking, then, based on an internal inspection of the roof, using a tape measure, you need to measure the distance from the inside, and then determine its position outside. It may move slightly upward. Then part of the roofing material should be removed to identify the true causes.

If the roof leaks - repair the bituminous roof

Repair bituminous roof depends on the extent and type of damage that can cause local termination leakage or full cover. If the roof was closed relatively recently and the material can serve for several more years, then proceed as follows:

1. From the place of the leak, measure the distance to the sides of at least half a meter.
2. Cut a piece of old roofing material down to the insulation and remove.
3. The resulting area is poured with heated bitumen or sealed with polymer-based mastic.

If the roofing material has lost its properties or the leak has been observed for more than several years, then in this case it will be necessary to completely replace all layers of the roof to the supporting material, making sure that the base is reliable. Then you need to re-lay the insulation and a layer of bitumen.

Repair of roofs made of profiled sheets or metal tiles

Metal tiles and profiled sheets are very reliable and durable, therefore, any leaks in them can occur only due to errors during installation or defects in the roofing material. Therefore, in the event of the formation of through damage in the roof, they must be soldered or welded with spot welding, and then treated with an anti-corrosion compound, or the sheet must be replaced completely. In case of loosening of the fasteners, they need to be tightened or replaced with similar ones, but larger diameter... If mistakes were made when laying the waterproofing, then it is necessary to dismantle the profile sheets and rebuild it again.

Ceramic tile roofing repair

Any violations tiled roof can be associated with two reasons:
1. External mechanical damage, for example, as a result of a falling tree.
2. Insufficient strength of the lathing. Under the weight of the shingles, the sheathing can bend, which causes a breakdown of the connecting locks and the roof begins to leak.

To carry out repairs, you need to remove a minimum of square meter shingles in order to determine the degree of damage. Then an auxiliary bar is mounted on the damaged rail, which at the time of repair will contain required row... After that, a part of the crate is replaced, it is impregnated with special water-repellent compounds, and covered with mastic on top. Then they put it in place, restore the waterproofing layer and mount the removed tiles in place.

Output
If the roof is leaking in the house, what needs to be done first of all is to determine the causes of damage to the roofing insulating layers and only then take remedial measures. When carrying out repair work without finding out the causes and consequences, new problems will arise quite often.

Roof leaks can ruin Decoration Materials, pieces of furniture, cause the development of mold, short circuits due to moisture entering 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.

The main causes of roof leaks

The most common cause of leakage is the abundance of precipitation that seeps through the roof through its damage. But if on 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 place of damage may not be exactly where the leak was found.

To find the reason, you can be guided by the following rules:

1. if it flows during rain, then the reason 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 drains. If they are clogged with ice or leaves, then the water does not flow out in the required volume and looks for weak points in the roof;
3. if there is no precipitation outside, and damp spots are still formed, then the insulation is to blame, which has absorbed excess moisture. The cause can be found in cracked tiles or an improperly organized apron.

How to inspect the roof?

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

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

The wind can tear and break the material, so the edge of the roof also needs careful inspection. 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 elements of the roof. It's great if you have an infrared camera at your disposal to immediately see areas of poor insulation and damage.

Damage that can be dealt with by hand

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

Often the waterproofing layer is broken at the junction of the battens of the lathing and rafter legs. In order to restore the waterproofing layer, you can dismantle a piece of roofing at the place of damage: first, it is better to strengthen the adjacent tiles with wooden wedges, and pry the required one with a trowel. Nails are removed from the rails, and parts that interfere with the repair are dismantled with a hacksaw. For safety, it is better to put a sheet of plywood underneath. 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 remnants of those that already exist are cut off at an angle, and then the missing part is precisely cut out from a separate piece of the slats, subsequently fixing it with the help of wood glue and self-tapping screws. Do not forget to treat the slats with an antiseptic. Finally, the shingles are laid.

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

Metal tile can only leak in the event of improper installation or at the points of attachment with self-tapping screws, if a poor-quality gasket is installed. Improper installation with your own hands cannot be corrected, but in the second case, a simple replacement of the gaskets with more reliable ones is required, which will not wear out after a couple of years.

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

Roof leaks - emergency situation that can occur after melting snow or rain.
If you do not pay special attention to this in a timely manner, then chronic stagnation of moisture can lead to the collapse of the ceiling, roof, the formation of fungus in the room, a short circuit in the electrical wiring, etc.

The main reasons for leaks are defects in the roofing surface carpet, failure of the drainage system, moistening of the thermal insulation layer and violation of the tightness of the coating adjacent to vertical structures (parapets, antennas, pipes, walls). Such damage can vary in scale. Accordingly, some will require minor repairs, while others will require the intervention of craftsmen and more complex activities, up to replacing the roof.

All leaks that occur can be divided into 3 classes:

• "Flickering" (formed in any season with large temperature differences);
• associated with melting snow on the roof;
• created immediately or after a short time after the next rain.

Thus, in order to properly eliminate the leak, it is necessary to correctly localize the problem, i.e. understand which element of the roof itself has ceased to function.

Leakage reasons:

• moistening of the heat-insulating layer due to technology violation;
• not enough effective work drainage systems;
• mechanical damage to the integrity of the roof and the geometry of the rafter system;
• violation of installation technology;
• the impact on the roof of biological and atmospheric factors that lead to its natural destruction;
• low-quality fasteners and roofing building materials.

The cause of the leak is assembly defects

Violation of technology in the construction of a roof is unacceptable. Quite often, to correct such errors, the roof has to be dismantled and installed practically from scratch. The factors of its successful installation are the following:

1. Projects created without errors

Improperly designed eaves, pitched roofs and parapets can exacerbate the problem of water drainage from the roof. Wherein big number complex elements of architecture and the inconsistency of their placement with ventilation can lead to the emergence of unventilated areas.

2. Technological installation of the roof in compliance with all recommendations

When creating a roof device, it is important to provide reliable hydro and vapor insulation, ventilation of the thermal insulation layer by installing ridge and cornice ventilation vane and air vents. If the vapor barrier is incorrectly laid in the structure, condensation may form, which will provoke the ceiling humidity inside.

3. Correct selection building materials and contractors

It is very important to use only high quality building materials and accessories. The manufacturer must give a guarantee for his products. For installation, it is necessary to involve craftsmen who have certificates and licenses.

What to do if the roof is leaking at home:

1. Initially, you need to inspect the roof. If the leak is not very significant, then the roof can be tested independently. First you need to go up to the attic and check the condition of the waterproofing for mold, rot, wet places, rafters, flooring and decking. For example, moisture can discolor the finish or leave dark marks on the wood.

The next object of inspection is laid in the attic electrical wiring... Any damage found in it must be repaired immediately.

2. After you have checked the inside of the roof, move on to external studies. Inspect the ridge for waterproofing and the integrity of its elements. Pay special attention to the fastening of metal aprons in the area where the roof adjoins to vertical structures and the condition of the insulation. Going down to the bottom of the roof, make sure that no plant debris has accumulated on the valleys. Examine the bottom layer of the roof covering and the eaves board - their integrity can be damaged by rain and strong wind... Check if the ventilation ducts, funnels, gutters and drain pipes are clogged with any debris, whether lichens and mosses have formed on the slopes, and on the roof itself - bubbles, chips, cracks, holes and dents.

3. If an external examination did not reveal any damage, but the leak continues, you should wait for precipitation, go up to the attic, find the place of moisture penetration and mark it with chalk. In dry weather, it can be patched.

Remember that roof repairs and inspections are very risky, as the slopes can be slippery and steep, high and suddenly dizzy. All these are pretty good reasons to turn to professionals for help. The roof repair technique involves not only detailed diagnostics and the selection of special building materials, but also the use of special equipment. Today, many firms examine roofs with an infrared camera. It is able to quickly detect a leak and visualize the technical condition of the roofing system. Based on the data received, the foremen determine the nature and scope of work and make an estimate. Further, the owner and the contractor enter into an agreement prescribing warranty obligations, terms of payment, rights and obligations of the parties.

How to fix a leak in the roof?

Removing roof leaks:

1. If a metal roof is leaking

Metal tiles are durable and high-quality building materials. Its flow is practically impossible due to wear. However, sometimes unforeseen circumstances happen:

• an error occurred during installation;
• there was a loosening of fasteners;
• mechanical damage, etc.

For minor damage, the surface can be sealed or patched with steel. In case of large damage, the sheet changes completely, and the gaps are removed with a special adhesive tape.

If scratches are found, they must be covered with a special paint to prevent corrosion.

The most serious repairs are required in case of incorrect installation of the roof. The most common cause of leakage in insulated pitched roofs, including those covered with metal tiles, is the use of cheap perforated polyethylene films as steam and waterproofing, which do not remove moisture from the insulation well enough. It is best to replace them with a superdiffusion membrane that fits directly onto insulating material... However, this method involves the complete dismantling of the roof.

In order to protect the roof from leaks, it is recommended to install snow guards on it. In winter, they will restrain the flow of snow, and in spring, melt water will flow between the waves of metal tiles.

2. If a metal roof is leaking

Reasons for leaks in the roof, which is covered with galvanized iron:

• mechanical damage;
• corrosion;
• violation of the tightness of the seams that fix the sheets of coverage.

Most often, holes and holes are repaired as follows:

• initially, you should clean the damaged area with a metal brush;
• then cut out a patch from the roofing building material, which will be 50-100 mm larger than the damaged area;
• then the edges of the patch and the damaged area are covered with flux and soldered to each other with a soldering iron;
• after the solder has cooled down, its excess is eliminated with a file;
• at the end of the work, the roof is painted in whole or in part.

In case of large damage to the metal roof steel sheets completely replace, using electromechanical special devices for seaming the folds.

3. If a slate roof is leaking

It is quite easy to repair a slate roof. However, you need to move along it carefully, since this material is very fragile. In this case, it is better to use a ladder-ladder, which evenly distributes the mass of a person over the surface.

Repair slate roof comes down to sealing not very large chips and cracks. For this, a special solution is used, which contains cement and fine sand in a 1: 2 ratio. Another sealing method is the butyl-based adhesive repair tape:

• the damaged area is wiped with a cotton cloth, which is first moistened in gasoline or white spirit;
• then the protective paper is removed from the tape, and its piece is glued to the damage, overlapping by 30-50 mm.

These ribbons are covered with a non-woven material on top, so they can be easily dyed in the desired shade later.

To prevent the steel nails fixing the slate sheets from corroding, they are coated with oil paint or drying oil.

If the size of the gap is quite significant, then it is recommended to change the entire sheet, or place a piece of slate under it, which has the same wavelength.

4. If the roof is leaking from corrugated board

The roof, which is covered with corrugated board, can serve reliable protection structures over a long period, however, subject to all regulatory requirements. The only reason for the repair work is natural disasters... In this case, the repair is reduced to removing the damaged sheets and replacing them with new ones. Sometimes, with poor-quality work of the masters, over time, a leak can form at the junctions of the building material with the crate. This occurs due to the fact that the self-tapping screw was screwed at an angle to the plane of the sheet. Thus, the rubber pad deforms and loses its waterproofness. In such places, the leak can be eliminated by replacing the self-tapping screw with a new one and covering the hole with sealant.

5. If the roof is leaking

Most often, when constructing a roof in multi-storey buildings roll building material is used.
It is this type of it that is most susceptible to flow, since it is budget option with rather low quality. How to seal the leak in the roof?

Repair soft roof it is created only after its complete drying. Initially, the place of the leak is visually determined and, depending on the nature, a certain decision is made.
If a ruberoid swelling was found, it means that water has leaked under it. To remove the defect, cut the swollen area, dry it, smear it with mastic from the inside, and then press it back. If tears or cracks occur in the material, a patch is applied, which is applied over the damaged area. On both sides it must be smeared with mastic.
