Step-by-step instructions for repairing a soft roof made of rolled materials. Soft roof repair: technology, estimate and SNiP rules How to make an estimate for repairs

Average service life soft roof reaches 10-15 years, but this is the case if all the features were observed technological process. The “life” of a roof covering is the longer, the more carefully and regularly the maintenance of its surface is carried out. But it is worth noting that even with systematic care, from time to time there is a need to repair a soft roof, and there may be several reasons for this.

1. Emergency.
2. Current.
3. Capital.

emergency repair necessary for emergency restoration of a soft roof to its normal performance characteristics. Most often, at this time, the coating is replaced in places of actual and alleged leaks. Reconstruction is subjected to from 5% to 20% of the roof area. Repair is the installation of patches in critical areas, less often a part is replaced roofing material.

Current repairs cover from 10% to 40% of the total area roofing. It is recommended to be carried out annually after a scheduled inspection of the surface of the roof of the house. The following activities can be carried out as works: replacement of part of the roofing or patching.

This roof is in urgent need of professional repair.

Overhaul necessary when more than 40% of the roof area needs to be restored. In order to fully normalize performance, the entire roofing or most of it is replaced.

Necessity repair work is usually caused by the destruction of the bituminous layer, which leads to a decrease in hydro and vapor barrier characteristics, which means that water from the outside begins to flow into interior spaces Houses. If you plan to repair a soft roof with your own hands, then it is worth studying the entire sequence of work, from assessing the condition of the coating to final stages restoration activities.

When repairs are needed

To understand how much work awaits the master, you need to climb the roof and assess the damage. When examining, pay attention to following points:

• the presence of delaminations at the junction of panels of soft roofing material;
• the appearance on the surface of the roof of pits and depressions visible to the naked eye, in which water accumulates;
• the appearance of blisters and bubbles on the surface of the roof: this is evidence that water has seeped under the layer of material;
• assess the degree of damage to the roofing from stagnant water - the appearance of rot, mold or fungus;
• check the roof for mechanical damage - cracks, tears, abrasions, deformations.

Important! Inspection of the roof should be carried out annually, and not once every 2-3 years, as is often the case. Early identification of defective areas will allow you to fix the trouble more quickly and cheaply.

The presence of bubbles on the roof surface indicates that it is time to start repair work.

An objective assessment of the damage will make it possible to draw conclusions - whether a major overhaul of a soft roof is needed or a small restoration can be dispensed with. To determine the sequence of operations, as well as to see the cost and the full scope of work, an estimate will help, the preparation of which should be the next step in repairing a soft roof.

Subtleties of budgeting

Sometimes you may come across information that it is necessary to draw up an estimate only for major repairs of the roof. This approach cannot be considered correct, because the estimate allows you to financially assess the amount of work, as well as systematize the data for the purchase necessary materials.

The estimate should take into account a complete list of repair activities, namely:

• dismantling of the old roofing - completely or only in the volume of the damaged area;
• preparatory work for laying new roofing material;
• direct installation of a soft roof and sealing of seams;
• creation of the upper waterproofing layer.

Also, the estimate should include the cost of purchasing consumables and combustible materials, and take into account the payment for the delivery of purchased products.

Photo of defects in the coating of a soft roof with detailed description will greatly facilitate the calculation of the required amount of materials for repairs

If it is difficult to decide on your own how much the soft roof repair technology will cost, then you can submit an application for the formation of estimates to professional builders. To prepare the document, they will need the following information:

• full plan roofs with the presence of all measurements;
• the thickness and height of the parapets, the location and length of the cornice overhangs and their junctions;
• the location of shafts, pipes and other roof elements, indicating their number and size;
• description of defects or their photos to assess the condition of the roofing;
• list of planned works;
• name of the roofing material selected for repair.

Having received on hand financial assessment future repairs, you can start choosing specialists or plan self-conduct works. It should be noted right away that the repair of a soft roof should be carried out taking into account the appropriate normative documentation, where both the work itself and the materials that must be used are regulated.

Important ! Often the experience of a team of craftsmen is adequately replaced by SNiPs, GOSTs and other rules. After all regulations do not take into account fast updating construction market, its development and the emergence of new options for soft roofing with more successful characteristics.

Minor roof repairs

Depending on the type of defect, several options for work are possible:

1. Creation of "patches" in places of damage to the material.
2. Connecting broken joints.
3. Refurbishment the old way.

Important ! If the restoration work will be carried out by professional builders, then the latter option will be preferred, since the first two are considered a temporary and poor-quality measure.

Repairing a soft roof requires professional skills and the ability to handle special tools.

The installation of patches involves local repair of the coating and is performed according to the following scheme:

1. All visible defects are removed - cut out or pierced.
2. The surface of the roof is cleaned of dirt, dust and debris.
3. The damaged area is filled with sealant or bituminous mastic.
4. Ruberoid is applied to the mastic larger area than the area being repaired.
5. Another layer of bitumen is applied on top, which is distributed with a roller over all surfaces with an emphasis on the edges of the patch.

Important! This method has poor efficiency, since soft roofing sometimes has hidden defects, which are very difficult to detect.

If the task of the masters is only to connect the divergent joints, then it is quite enough to perform the following work:

1. raise and thoroughly dry the space under the roofing material;
2. coat the damaged area with bitumen;
3. lay the roof in place;
4. re-treat the joint with bitumen.

Repair of a fragment of the roof, in which there is no need for disassembly large area roofing

The method, which is called "the old way", is considered the most effective and high-quality for carrying out minor repairs roofs. Its essence lies in the fact that a new layer of material is laid on the old roof, cleaned of debris and dirt, which is used as a base. It turns out an updated coating with a complete restoration of all operational characteristics of the roof.

However, there are limitations to be aware of when using this method. Repair is not carried out according to this scheme if:

• the old roof is very badly damaged;
• this is not the first roof repair and the number of layers of old material has already reached eight.

Important ! The fusing of a new layer significantly increases the load on the floor supports and walls of the house. Before starting work, it is necessary to calculate how much weight can be added without endangering the building structure.

Overhaul stages

In some cases, the roof is already in such a neglected state that local repairs do not help. Then it is worth considering other options, which are based on the removal and replacement of the old roofing carpet. Estimate for the repair of a soft roof in this case increases significantly, and the works themselves are called capital. Activities are carried out in certain order, but it is worth noting that the expediency of some stages is assessed by the craftsmen on the spot. When good condition any layer roofing cake» Some jobs may be skipped.

The overhaul of a soft roof is a certain sequence of works

Full list includes:

1. Dismantling of the old roof;
2. Dismantling cement screed and removal of the heat-insulating layer;
3. Restoration of the vapor barrier layer;
4. Putting in order the internal drain;
5. Installation of thermal insulation;
6. Carrying out demolition when using sand;
7. Installation of funnels for internal drainage;
8. Installation of cement screed;
9. Primer screed;
10. Roofing installation taking into account all technological features;
11. Roof coating with fire retardant or reflective composition.

If you have to perform all of the above work, then the cost of repairs may exceed the amount of the cost of a conventional installation. It will not be possible to avoid this, since in any case the work will be associated with dismantling and removal of construction debris.

Important ! The simplest overhaul includes: a complete replacement of a soft roof with partial renovation foundations, as well as revision and partial replacement of some elements of the roof.

Checking the quality of work

The main question that confronts the owner of the house after the repair of the roofing: how to check the quality of work. There is no single line of conduct, but you should pay attention to the following parameters:

• Visual inspection of the repaired roof. Rolls of material should lie flat, without visible distortions, excessive overlaps and intersections.
• Assessment of the state of the edges. They must be perfectly melted and fit snugly to the base, otherwise the sheets can be torn off during the first bad weather and strong winds.
• The behavior of the roof during rain. This is the most important indicator, as it really demonstrates the quality of the work performed.

Important ! Do not forget about the guarantees that any handyman working for hire must provide.

Soft roof after a quality repair

In general, when accepting work, you can focus on the requirements of SNiPs and SPs, since in any case they should serve theoretical basis for any major renovation. Even if a roofing material not specified in them is used, the installation requirements remain unchanged already. for a long time.

Winter work

Repairing a soft roof in winter is a separate topic for conversation. Of course, it is not recommended to carry out any work on the roof during the cold season, but there are situations when it is simply necessary to carry out emergency repairs.

Important ! Repairs in winter should be carried out at an increased level of safety.

In winter, it is worth doing the restoration of the roofing if:

• the roof of the house was seriously damaged (due to a snowstorm or when a large and heavy object fell);
• the amount of snow that has fallen has caused the roof to sag;
• the thaw led to the formation of leaks.

Clearing a soft roof from snow cover before starting repair work

Any of these situations can lead to deformation of the roof, as well as walls and ceilings; cause short circuit or even a fire. To avoid this, it is recommended to restore the roof immediately, especially since this can be done at almost any air temperature.

Like any other complex repair, winter activities must be carried out in compliance with certain rules:

1. The choice of roofing material. Low temperatures badly affect many types of coatings, so it is very important to choose an option that will not break in the cold.
2. Among the materials recommended for repair, it is worth noting: soft tiles, corrugated board, metal tile. For work, it is better to choose frost-resistant sealants that react neutrally to sub-zero temperatures.
3. It gets dark quickly in winter, so you should think about lighting the roof in advance, otherwise you can interrupt work immediately after dismantling the roof at the site of damage.
4. Safety. It is worth considering in advance the clothes and shoes for work. In addition, you need to take with you everything you need to protect yourself from bad weather.
5. Snow must be removed from the roof before repairs can begin. To do this, use a scraper with a rubberized surface.
6. The patch material must be kept warm until last moment.
7. Roof repair in winter should be entrusted to professionals, as in difficult conditions it will be difficult for an amateur to cope.

It is possible to carry out any roof repair work by working with a partner. However, you shouldn't do this on your own. Installation new roof you can still arrange it yourself, but for repairs it is advisable to call professionals. Only in this case, you can be sure that the assessment of the condition of the roof will be carried out correctly, the estimate is drawn up taking into account all the features of the repair, the necessary materials have been purchased and all work has been carried out in accordance with the requirements of regulatory documentation.

Leave your roof repair worries on the shoulders of our specialists!

Soft roofing is quite easy to install and available to the vast majority of developers, which is why it has remained very popular for many years. Unfortunately, nothing lasts forever, and often breakdowns happen to any objects and mechanisms that surround us, and roof cladding is no exception. Repair of a soft roof happens quite often, and the owners of the house have to fix it, sometimes even a couple of times a year people eliminate the defects that have appeared. The only good news is that for such work it is not necessary to involve craftsmen, because the entire restoration process can be done by hand.

A repair plan is usually drawn up after a thorough revision of the roof, which allows you to identify all the problems that have arisen. There are two standard way roofing repair:

• capital repairs of a soft roof;
• ongoing troubleshooting.

Each of these methods is performed using a separate technology, within which it is recommended to use various materials, and in case of urgent need, you can take up work even in winter.

The main reason for the frequent wear of roofing material lies in the properties of bitumen, which is susceptible to sun rays and at high temperature begins to melt, hence the defects, expressed as swellings and irregularities, affecting the further operation of the structure. The thing is that when precipitation falls in the formed depressions, rainwater accumulates or melted snow seeping through cracks in the bitumen. But even in winter, you can encounter some problems, because during the thaw the snow melts, and when the temperature drops sharply, it turns into ice, which expands the cracks in the material and tears it.

To determine if the sheathing needs repair, carefully examine the roof surface. If in some places the waterproofing has peeled off, cracks have appeared, bitumen has swelled up, or depressions or moss have sprouted, repair of the soft roof is inevitable. If the defects are minor, you can get by with a small repair and can easily handle it yourself.

Current roof repair

Let's make a reservation right away that major repairs can be made not so expensive if a preventive process is carried out every three years. Concerning current repair, then it provides for minimal cladding errors, and you do not need to dismantle old roll materials with dried mastic, which, in fact, require repair. Here you will need to update the existing layer, namely:

• elimination of bubbles;
• replacement of funnels for water flow;
• replacement of parapet covering or cornice overhangs;
• covering the old layer with primers;
• fusing new waterproofing.

Experienced craftsmen advise Special attention pay attention to the most problematic places, which are the joints of roofing elements, parapet structures and walls, as well as those areas where drains are fixed. In some cases, you can limit yourself to patches, but they often do not give a sustainable result and are not a guarantee of the further operation of the roof without leaks.

The soft roof repair technology consists of several stages, namely:

1. Cleaning the surface of debris, dirt and moss;
2. Examination of the surface for the presence of rot, and if it is found, such segments must be cut off with the capture of intact material (up to 2 cm on each side);
3. Leveling irregularities with special mastic, which will require mortar materials such as a cement composition;
4. Cutting off all bubbles, removing dust, drying the surface and leveling it to firmly fix the patch;
5. A patch is cut from the new material with an allowance of 5 cm;
6. Lubrication of the surface with mastic and gluing patches.

We draw your attention to the fact that reverse side the patch must be treated with bituminous mastic. Further in the work, you will need a burner, which needs to warm up the patch, after which it is pressed against the press.

Repair over the old coating

In professional circles, such an expression is known as “repair the old way”, which means that it is not necessary to dismantle old roofing materials, and defects are eliminated on top of them. This method is much cheaper and easier to implement than the overhaul of a soft roof. It can be easily done with your own hands, so this method is most often resorted to.

Laying new layers on top of old ones

In this case, the old roofing materials, on which defects have been identified, will serve as the basis for a new coating. The final coating can be applied in one or two layers - it all depends on the scale of the disaster and on the financial capabilities of the owner of the house, but a double carpet, of course, is better and more reliable, since its strength is higher. However, one cannot fail to mention the fact that it is necessary to take into account the possibilities truss system, because here the load on the roof surface increases by 5kg / 1m2 due to the roll lining, and the mastic on which it is glued also gives additional weight. Repair of a soft roll roof according to this principle is suitable for a roof that is not in a completely deplorable state. If the old roll lining is completely bad, the risk will be unjustified, and it is better to immediately tune in to a major repair. Also, this method should be abandoned if the layers of bitumen laid earlier exceed allowable rate(maximum 6 - 8 layers), again due to the weight of the materials.

Capital repairs of a soft roof

If you conducted an audit and found that a significant roof area was damaged, and defects reach 60% of the entire surface, patching and mastic will not work here. In this case, only the complete dismantling of the dilapidated damaged lining and laying can help correct the situation. soft material in a new way. As a rule, to overhaul resorted to in case of regular and heavy roof leaks, as a result of which the insulation is damaged and loses its properties or the sheathing freezes.

The minimum set of work on the overhaul of the roof includes the dismantling of bitumen and its replacement with new material lubricated with mastic, the replacement of funnels and cornices, the drying of the insulation with the help of special devices, the replacement of the parapet structure. If the condition of the roof is more than deplorable, and the defects have affected the truss system, it will be necessary to update not only the cladding, but also the frame with vapor barrier and insulation, and the order of work will look like this:

1. We dismantle old materials;
2. We eliminate screed defects;
3. We carry out the entire roofing process in a new way.

Do-it-yourself overhaul of a soft roof is best done with assistants, because here you will have to tinker not only with bitumen and mastic, but you will also need to install some roof elements that are difficult to lift alone, let alone fix.

This video shows in detail the entire process of installing the roof. After viewing, you will be able to do all the work yourself.

During the operation of the roofing, especially if the installation technology of the soft roof was violated, it may be necessary to repair the roof. The need to repair the soft roof of the house, and other buildings, arises as a result of the appearance of defects on the surface of the roofing material. These defects can be a swelling of individual sections of the roofing, the appearance of tuberosity, a violation of the waterproofing at the junction, a violation of the integrity and attractive appearance protective coating, etc. All these defects require repair work, and in especially difficult cases - and complete replacement roofing material. Our company provides services for the repair of soft roofs, the prices for which are set at a favorable level for customers.
