Problems with a roof coating of a flat type, as a rule, arise due to waterstools on the surface, wetting the thermal insulating layer or evaporation of moisture from the roofing carpet. As described reasons, the following coating damage may appear:
Periodic preventive inspection will help you limit exclusively by current local repairs. Otherwise, after a while you will have to completely replace the coating, but also to spend money on the restoration of the premises. It is recommended to carry out work only on warm days and dry weather.
In order for the repair of a flat roof to be proper quality, our specialists perform all work on a specific plan:
Flat roof has a number of advantages, so it is very popular. Ruberoid and sheets with a folded edge are often stacked with violation of technology, which leads to the formation of leaks and loss of strength. At the nearest strong wind, it will noticeably. If the surface has become unusable, our company will be able to perform quality. Our main a distinctive feature The market for the provision of these services is a profile orientation. We are only engaged in the roofs, not trying to manage to do so much in all areas. Therefore, we offer the most best repair Flat roof in Moscow.

Flat roof wins in comparison with the scope in the cost and simplicity of installation. But there is also a disadvantage: relatively often have to repair. As with the use of which materials it is carried out - these questions will be the subject of this article.
The work on the restoration of the roof cover is made to divide into three categories:
Current repairs is a complex of work aimed at maintaining the normal roof state: minor damage and defects are eliminated, which in the future can lead to leaks. Usually the cumulative area of \u200b\u200bthe recoverable areas does not exceed 40% of the entire roof area, while the repairmen are most often limited to the surface layer manipulations.
Problem places are detected by inspection, which is recommended once every six months, as a last resort - once a year.
It is very important to spend maintenance In a timely manner, since small damage on a flat roof is quickly developed into large, which will attract a significant increase in the cost of recovery of the coating.
With strong wear, when the area of \u200b\u200bthe plots with damage or unsatisfactory state exceeds 40% of the roof area, resort to a full-scale reorganization of roofing cake. In fact, the roof, starting with vapor barrier, is not anew - only a small part of materials in good condition is used again.
When performing a capital repairs of a flat roof, all layers of roofing pie are dismantled and stacked
Emergency repair has to be resorted by urgent, if the roof gave flow. If the current and overhaul is usually performed in the warm season, the emergency make when it is necessary, and this is its feature.
In winter, emergency works are performed necessary for urgent elimination of roofing defects
As part of emergency repair, as the current, usually produce manipulations only with the surface layer. In most cases, the area of \u200b\u200bdamaged sections does not exceed 20% of the entire roof area, but if necessary, the coating is replaced in more significant volumes.
During repair work On the roof often you have to dismantle the old roofing coating. It is clear that at that moment the building is deprived of the protection against precipitation, so it is necessary to prepare very carefully so that nothing prevents repairs to repairs in the shortest possible time.
For the device and, accordingly, use four types of materials.
The category of bitumen materials includes a traditional rubberoid, which is a bitumen cardboard, as well as newer coatings of the type of metalism and pholoisol, which are hardened with foil.
Folgoisol is a multi-layered design with an external coating of aluminum foil
Bituminous waterproofing is the cheapest, but also the least durable - the material comes in disrepair in 5-7 years. So short service life is explained by the following disadvantages:
Adding a small amount (usually no more than 12%) of various polymers allows to increase the frost-resistance of the material and its plasticity, as a result of which the service life is extended to 15-20 years. In addition, glass choles, fiberglass or polyester are used as the basis instead of fragile cardboard, due to the material acquires increased resistance to mechanical effects.
Rubext is manufactured over more modern technologythan rubroad, therefore it has a few times longer service life
IN currently According to this technology, a wide list of materials are manufactured, for example, bikrost, a scheduling, rubles, hydrohoteloisol, glass astronomer, glassobit, linocur.
Special success managed to achieve when mixed in bitumen rubber crumb, elastomers, thermoplastoplasts and thermoplastics. Materials manufactured by this method are produced under the marks of Philipol, thermoflex, Dneproflex and Dnipromaster, Lürbier, Elabit, Mastoplast, Isoplast, etc.
Often, bitumen-polymeric materials are called EuroBeroid. In addition to increased resistance to negative factors, it has one more important difference from the frontier): the laying can be performed by the method of burning, for which the lower surface is heated by gas or gasoline burner.
To fix the EuroBeroid, it is enough to warm up its bottom layer with a burner - gasoline or gas
At the same time, the EuroBeroid inherited from his prototype and some disadvantages: it also has to lay in a few layers, while, with a rare exception, it takes a spill of the surface by stone crumb.
The cost of bitumen-polymeric materials is higher than the traditional runner, but at the expense of a rarely carrying out repair work, the costs of the roof content are reduced by 2 times (from the calculation of 40 years of operation).
Single-layer membranes are a fundamentally different type of coating, which is manufactured from synthetic rubber or polymers. He has a number of advantages:
You can fix the membrane both with the help of glue or bitumen mastic, and by means of screws. Due to the long service life (more than 25 years), single-layer laying and rare need to carry out repair work, the maintenance of the roof over 40 years of operation will have to spend 4 times less than in the case of bituminous roof.
Repair of the roof using a single-layer membrane "Ecoplast" can be carried out at any time of the year
The release of membranes in Russia was mastered for quite a long time: the "Cromel", "Ecoplast", Logicbase, "Rutus" and others have proven themselves well.
Roofing mastics are liquid compositions that are applied to the roof by any of the following ways:
After a while, the mass is polymerized and turns into an elastic waterproof film similar to rubber. Because of this similarity, roofing mastics are often called liquid rubber. The film is extremely elastic - does not break with a relative elongation to 1000%. This means that during the shrinkage of the building, the roofing coating will remain as much.
After the polymerization, the roofing mastic turns into a waterproof film like rubber
In comparison with rolled materials, mastic has an important advantage: with any roof area, the coating will be seamless. They are very useful for repair work, since they allow you to fill the most hard-to-reach cavities.
Roofing mastic are produced both in one-component and two-component execution. In the second case, the main composition must be mixed with a hardener.
According to the composition of mastic, they differ quite strongly, respectively, and their service life is different:
To glue the roll materials, you need bitumen mastic (not to be confused with roofing mastic - "liquid rubber"). It can be purchased in the store, and you can do it yourself. There are two varieties of this material:
Cold mastic is prepared from such ingredients:
The bitumen is heated in some tank and withstand some time so that moisture is completely evaporated. The temperature at which evaporation is carried out is approximately 180 o C. Then the filler is poured into the bitumen, after which the mixture is thoroughly stirled by a wooden stick. Next, it must be poured into gasoline.
If bitumen is heated, then it is necessary to pour into gasoline, and not vice versa.Otherwise, it is possible fire. After cooling, mastic can be applied by destination. It should be borne in mind that it is not stored for a long time, so it makes no sense to prepare a large amount for the future.
The cooking technology of hot bitumen mastic provides bitumen cooking at a temperature of about 200 o C. During this process, the filler is gradually added, the bitumen is mixed at the same time.
If you need a small amount of bitumen to repair, it can be heatled in a metal bucket, and special installations use for large volumes
If, when mixing bitumen with a filler, the temperature of the mixture falls below 160 o C, the material will greatly lose in quality.
For insulation, the roof should be used the material that is able to keep the weight of the coating and snow and at the same time not very deformed. These are:
With large volumes of work it is useful to make a calculation essential materials And calculate their cost. Having in the hands of the estimate, the owner of the structure is guaranteed to acquire everything you need, so that during repair it will not have to be distracted by secondary actions. In addition, the estimate will show which means it will be necessary to allocate, because with large-scale repair, costs can be very significant.
If the roof repair is decided to entrust the brigade of hired workers or specialized firm, To prepare the estimate, they need to provide the following information:
For work, you will need:
Application gas burner Requires increased attention from roofer to safety rules
With help construction fabric You can quickly dry the repaired area or remove the roofing material.
Broad brush - Maclithic - Apply primers and mastics
Each type of defects on flat roofs is eliminated by its methodology.
The sequence of actions is as follows:
The easiest way to repair such damage is to set the pay. Before that, it is necessary to determine how deeply moisture penetrated in roofing pie.
Plot with a crack or bloody open with a cross-shaped outbreak
The layer of mastic is applied to the open and treated area, and then it is placed on it, the edges of which are also missing bitumen
Installing a patch is not always guaranteed to ensure the desired result. The master may not notice hidden damage, so after repairing the roof will still flow. Often make a mistake by setting the pay over the place where water appeared on the ceiling: in fact, damage can be at a distance of 2 m from the place of leakage.
Taking into account the whole said, many masters prefer to simply wake on top of the worn coating new, which is customary to be repaired in old age. It should be borne in mind that laying one after another new layers significantly increases the load on the walls. For security reasons, it is not allowed to lay on the roof of more than eight layers of coating, but at least their number it is desirable to calculate the walls and overlap to strength.
Single-layer membranes, which were described above, steadyly carry atmospheric effects, but may be damaged, for example, when removing snow from a roof with a metal shovel. The tightness of such a coating is restored as follows:
If there was a separation in the seam area, the detached area is apparent in the same way, previously treated with the inside of the solvent. If the separated area has a length of more than 5 m, it should be restored using a special repair tape, for example, Eternbond.
Cracks on the mastic coating appear as a result of aging material. Recovery is carried out by the same mastic from which this coating was performed. They act like this:
With extensive damage, the repair layer must be reinforced with a fiberglass with a density of 100 g / m 2. First, the sprayer is applied by a layer of mastic, then put the grid and then they are once again applied to mastic, which must be completely hidden.
Any repair begins with a roof inspection. That's what you need to pay attention to:
Special attention should be checked by plots adjacent to pipes, parapet, ventilation mines and other objects available on the roof.
If the damage occupies more than 40% of the roof, perform overhaul, which includes the following steps:
The overhaul of the flat roof begins with the complete removal of the old roofing and under it concrete screed.
When using wedge-shaped heat insulating material The roof flashes can be done already at the stage of its insulation.
Flat roofing can be done by pouring over the insulation layer of clay
Before filling the screed on the surface of the roof set reinforcement grid and wooden lighthouses
It is not always possible to fulfill the flasher correctly. To reveal errors, carry out such a test:
In such dents, after their drying, they need to pour the mastic to the thick layer or glue a piece of the roll material (not thicker 1 mm), after which it is possible to fit the finishing layer with a stone sprinkler. If there are no powders (ordinary ruberoid), it is applied independently on a layer of hot mastic, into which the stone crumb is pressed by a rink.
To reduce the frequency of repairs of a flat roof, it is necessary to initially bet on high-quality materials. And when servicing should be protected from mechanical damage - when cleaning the surface from snow and the land is not recommended to use a metal shovel or scrap.
Arrangement and repair of flat roof is made by two types of materials: soft or bulk. They provide excellent sealing of layers of roofing, protection of the house from damaging environmental impacts and a long service life. There are typical damage to the roof of soft materials, which periodically arise independently of the quality of the materials used.
Find out if there is a need for the reconstruction of the roof, you can with a thorough examination of its surface. You can detect the roof defects at home, if you just go through it. Damaged places can make a crunch, to rebuild and swell.
Estimation of the roof status
Types of damage to flat roofing:
If you periodically hold a preventive examination of the roof of the house for the presence of defects, then a small current surface repair can be performed with your own hands. But if you do not do this on time, the defects will gradually progress, and the roof can start leaking. In this case, it may be necessary not only overhaul of the roof of the house, but also restoration interior decoration premises.
Defect roofing The consequences of late roof repair:
Deformed coating place This will help reduce the cost of the maintenance of the house.
Depending on the size and nature of surface defects, two varieties of repair can be noted.:
Partial replacement of roofing There are two effective methods to repair a flat roof.:
PVC membranes are a soft material for repairing the roof, with which you can repair easily and quickly. A large plus of such coatings is that the laying is possible by one layer directly to the previous coating from the rubberoid. The only requirement - the surface must be clean (without stones, garbage, old fat spots, water puddles).
The structure of the membrane roof For work, you will need:
Rolls roll on the roof surface and cut the necessary pieces of cloths. The blades are stacked by 12 cm. The edges of the canvas are fixed by a dowel-nail every 40 cm. The edges are combined with heated air from the welding machine. At the same time, the flow of hot air is sent under the leaf and immediately rolled the roller. This method is justified when repairing extensive areas.
This repair technology is much more economted, but the surface must be perfectly cleaned. Flooring material is made in two layers. The first is the main, and the second is decorating. Thanks to a special powder, a decorative rubberoid is not afraid of the Sun, frosts, does not crack and does not dry, himresistant and has a long operational period (about 30 years). Material is produced in rolls.
Pressure material Materials and tools for work:
The bands of the desired length are measured and jerked again for convenience in rolls. Each canvas warmer with a gas burner and rolled down, holds to not burn, iron hook. In this case, the material is firmly attached to the surface. On top of the lower layer are placed on the same algorithm. Then two layers are melted at the same time, ensuring the reliability of the clutch and durability of the coating.
A small repair of a soft roof of the house can be done using an ordinary ruberoid. He certainly does not have all the advantages of modern analogues, but with small roof defects, you can use pieces of rubberoid, laying them on melted bitumen. The material can be laid even on top of iron or slate surfaces.
Elimination of small defects With small cracks of the slate plane will help flaps of fabrics in oil paint - They can close small damage.
Large damage fragments are subject to replacement or complete roof overlapping with new material.
The technology of insignificant current repairs does not require such preparations, it can be spontaneously without any preliminary preparation.
Planning overhaul of the roof, it will be quite reasonable to preliminarily calculate the cost of repairing the roof from rolled materials.
Previously, it is necessary to calculate the consumption of the material. Procedure for repairs planning:
1. Performance of the measurement of the territory, within which the coating is planned.
2. Drawing up a list of all required materials, taking into account the nature of defects.
3. Adding to the list of materials for the manufacture of cement-sand solutions if it is planned to update such sections of the roof.
4. To the resulting result, add 10-20% of the distribution of materials.
5. Consider the offers of various building materials stores, take note of the promotion and conditions for delivery of materials.
Overhaul of the roof requires major costs and high time costs, but the procedure itself may well be done with their own hands, subject to ownership of some skills.
Full replacement of old coating Technology events:
In order for the overhaul of the roofing of the result and delivered the next ten years from holding such events, all rules should be followed when laying the coating. It should also take note of the fact that the coating condition will depend on the quality of the selected material. It is better to choose products of proven manufacturers.
The main function of a flat roof, as, however, and any other, is to ensure reliable protection of the house, therefore, and everything is in it, from atmospheric influences. Of course, with time or as a result of defects, which may have been admitted during its construction, looseness may form in the roof. In such cases required repair of flat roofing.
When pronounced wet stains are found on the ceiling and walls, it means that the roof is somewhere. It is clear that in a similar situation it is necessary in the design of the roof urgently reveal the cause of the leakage and immediately eliminate it.
It is possible that it will not be possible to find a problem place immediately because it may be away from the place of leakage. So to find " weak places»It is necessary to carefully examine the surface of the roof. It must be admitted that finding small defects with a soft roof on a bitumen material, for example, bursting bubbles or cracks, not so difficult. It is much more difficult to detect the source of leakage on the roof covered with a layer of gravel.
Accordingly, the nature of the damage to the roof is distinguished by repairing the current (up to 40% of damage) and capital. In the first case, it is assumed to "latch" local repair of simple damage, in the case of capital - carries out a solid repair of damaged structures.
Such simple defects, as, for example, cracks, blown, separated seams with laid roofing bands can be quite simply eliminated on their own. For this most often use bituminous mastic Cold curing, that is, when repaired, you can do without using a special boiler, in which the bitumen is heated.
This defect is usually a consequence of roofing bundle. If the sweat is dry, they impose a patch on it. In the case of moisture detection, it is necessary to find the place of leakage and completely replace the area affected by dampness. Need for special equipment to perform the current repair flat rolled roofing , not.
The elimination of bloating is schematically as follows.
To coating cracks on a soft coating, you can use any self-adhesive material for repair.
Patchworks on the roof, of course, do not give her aesthetics, so it is desirable to decorate them, applying paint or bitumen to the entire surface.
The need for major repairs occurs during damage to the structures of a flat roof. They can cause the wrong device. Consider several examples.
The insulating layer must have a vertical backstage at least 25 cm.
The list of cases when a solid repair may be needed, it would be possible to continue, but for all of them the total one is the need for certain costs that depend on the method of solving a problem. Among them are the following.
