Maintainability is a strong argument in favor of flexible materials used in the construction of roofs of private houses. Most damage to bitumen shingles and roll coverings can be repaired by the owner of the house without any problems.
He will not need complex equipment and fundamental knowledge an experienced roofer. You will need confidence in your own capabilities and the basics of skill according to which repairs are carried out soft roof low-rise buildings.
A convincing signal indicating the need for roof repair is usually trivial leaks. They appear for various reasons, which include:
To correct defects resulting from design violations, a major overhaul is needed. Not everyone is with him House master can cope without professional help. But the damage indicated in the second and third paragraphs is eliminated during current repairs. It does not require global dismantling, a large amount of work or highly complex operations. Almost all damages included in the current repair scope are accessible to an inexperienced contractor. Let's consider them.
Traces of damage to the integrity of the coating do not always appear during periods of active snow melting and rainfall. Although the ceiling, the cladding of the attic, and damp rafters that are wet due to liquid precipitation are reasonably considered to be one hundred percent indicators. It happens that atmospheric moisture that has penetrated under the coating first “cruises” along the waterproofing for some time, and then seeps into a crack that finally meets on its way. According to popular wisdom, water will always find a “hole” for itself, and is even capable of “sharpening a stone.” How can one fight against its influence from wood? rafter system, lathing and mineral wool thermal insulation.
For the sake of long-term service of the roof, inspections must be carried out regularly 4 times a year. They are needed for the timely identification of existing and emerging breakthroughs, which sooner or later will definitely make themselves felt. To ensure that the consequences of small punctures, cracks, and potentially dangerous swellings do not take on an emergency nature, the roof is inspected each time in two stages, these are:
It should be taken into account that wet spots identified from the attic do not always coincide with existing holes found in outside roofs. The causes and consequences of leaks are practically combined or are closest to each other by flat roofs. This is not typical for pitched structures: in reality, water penetrates higher than it leaves its destructive traces. The researcher of his own stingrays must certainly remember this circumstance.
A roof inspection allows you to understand whether a home craftsman can repair a soft roof on his own, or whether it is better for him to resort to the services of builders. There are no fundamental problems with current operations to eliminate defects in soft coatings. If the owner has not forgotten how to hold a tool in his hands, he is able to repair a roof covered with flexible tiles, membrane and bitumen-polymer roll material.
Minor roof leaks with shingles are corrected by replacing damaged elements. The most common reason for the formation of holes in it is walking in frosty weather, when the bitumen coating becomes brittle. You can make a hole by clearing snow with a shovel or dropping the tool on the surface. In addition, poorly secured shingles can be torn off by a strong gust of wind.
Gaps in the coating tend to grow larger, resulting in part of the shingles or an entire shingle being torn off. Even if the owner is not embarrassed by the loss of aesthetic indicators, the element must be changed. And to carry out the repair competently, you should familiarize yourself with the technology for repairing soft tile roofs and the sequence of actions for replacement.
It is not necessary to install new shingles that include three pieces with tabular ends. Sometimes replacing just one petal is enough. However, it is very useful to have a few in stock with a similar color coating. They are needed precisely so that the coating can be restored at any time.
Let's look at the sequence of work to replace 1/3 of the shingles, i.e. parts with a torn petal. To replace it, we need to remove that part of the tile that is covered by the elements laid on top. You cannot attach a bitumen piece over a piece of shingle that has not been removed. After all, the surface relief resulting from the “overlay” can become a new reason for the coating to rupture.
Algorithm for repairing bitumen shingles with one torn blade:
Both in the case of multiple damages and in the case of replacing the entire bitumen shingle, they act according to the given algorithm.
If a roof covered with flexible tiles leaks along the junction lines, then the reason should be sought in cracking of the sealant, peeling of the waterproofing carpets attached to the penetration, or again in a violation of the penetration technology. In such situations, the shingles in the repair area, most often around the pipe or along the parapet line, are unfastened. And after eliminating the defect using the described method, they are placed in place.
Gaps and holes in the roofing membrane result from improper use. Move on the roof with polymer coating permitted only by pedestrian paths, laid specifically for its maintenance. Paths are constructed from an elastomeric strip with an anti-slip texture, produced by manufacturers of this product. roofing material. To remove snow from the membrane, use a plastic or wooden shovel.
Small defects in membrane roofing can be repaired by installing patches:
At heavy pollution the surface around the hole, the patch can be placed under the coating and welded using a similar method. Device for manual welding You can rent it from a specialized company or a tool store.
If there is no welding device at hand to eliminate the defect, it is permissible to seal the hole with butyl rubber-based tape:
Materials used to repair the membrane must be compatible with the coating. Before applying the patch, the surface should be treated with primer.
In addition to holes and cracks during operation, flaws in the installation of the membrane may appear. The most common manifestation is peeling of the strip along the welded seam. In such cases, the coating is not patched, but the poorly welded strip is removed and a new one is laid. It is recommended to duplicate the new seam on top with a welded strip of material approximately 10 cm wide.
The fight against defects in bitumen and bitumen-polymer coatings is carried out along all fronts characteristic of soft roofs using characteristic ways repair. Common types of damage include:
It is not for nothing that holes in the roofing carpet, caused by incorrect operation, are at the top of the list of situations that need to be repaired. Damage to rolled material is often mechanical in origin.
Options for eliminating minor defects:
Impressive swellings and ruptures in area dictate the need for a major overhaul of the built-up soft roofing with the replacement of layers of the roofing pie that have become fairly wet. To prevent things from reaching major alterations, regular inspections should be observed. It is recommended to schedule repair work on days when the thermometer does not fall below +5ºС and does not rise above +18ºС. Deviations in both directions from the designated temperature limit are reflected in the elasticity and strength of the material.
If on the surface roll roofing depressions with a depth of no more than 1.5 cm have appeared; repairs are carried out according to the principle of eliminating bubbles:
Minor leaks in the area of roof penetrations are dealt with by opening finishing material and replacement of waterproofing pasting. Often an autopsy reveals that only the sealant layer is damaged. It just needs to be updated.
The situation is much more complicated with the elimination of leaks in the area of roof junctions and passages, if the problems are associated with peeling, cracking and destruction of the coating. Troubleshoot such problems as follows:
We also repair peeling roof coverings if the area of the defect does not cause any particular concern and does not suggest the idea of completely replacing one or two adjacent strips. In areas of peeling, you should try to separate the coating from the base and adjacent strips as much as possible. The base and separated material should be thoroughly cleaned and dried, and after drying, coated with primer. The lower sides of the separated coating are again heated with a gas burner and fused onto the base.
Actions to re-glue the peeled coating are carried out if the strip separated from the base does not have more significant damage. If there are large breaks and punctures, the entire sheet must be separated from the base and a new strip laid.
A soft roof can also leak due to poor-quality casings used to arrange communications crossing the roof. Rubber or plastic fixtures They might simply burst. Damaged equipment attributes are subject to unconditional replacement:
In fact, replacing communication accessories is carried out according to the same scheme as the initial installation. Watch a video that will help you study in detail the principle of repairing penetrations through a soft roof:
The presented examples of repair of soft roofing coverings will help get rid of most of the characteristic defects that plague owners of private houses. Compliance with recovery rules guarantees excellent result. And the owner can do everything with my own hands without the participation of roofers.
A properly installed soft roof will last 15 years. However, it is necessary to constantly take care of its ideal condition. After a certain period of use soft covering may need emergency or current repairs, and a little later - major ones. You can understand whether it’s time to restore the roof only after a thorough visual inspection.
Climbing onto the roof and assessing the damage to the coating will help you clearly understand how much work is expected. When examining a soft roof, you need to investigate the occurrence of problems such as:
You can verify that the soft covering is peeling off at the junction of the panels by carefully lifting the material
Bubbles or folds in the soft surface indicate that the material was not pressed tightly to the base when laying
Cracks in soft roofing often appear due to exposure to atmospheric agents.
After a critical inspection of the soft roof, you can make a decision regarding the type of repair - emergency, routine or major.
Emergency restoration of a soft roof is considered when they see that from 5 to 20% of the roofing area needs emergency assistance to normalize operational characteristics. To return the carpet to perfect condition, patches are installed in places where leaks have been detected or may soon appear.
Patches will help restore a soft roof if it has deteriorated by a maximum of 40%
Current repairs are necessary if 10–40% of the coating is damaged. It is expressed in partial replacement roofing carpet or patching.
Major restoration of the soft surface is a last resort. They resort to it, being sure that more than 40% of the roofing carpet has been severely damaged.
Patches will not help a significantly damaged roof. Significant destruction of the bitumen layer, deterioration of waterproofing and vapor barrier properties is dealt with by complete or at least extensive replacement of the material.
A roof with serious damage needs major repairs.
The set of tools for repairing soft roofs includes:
Technoelast, bireplast and fiberglass are well suited for restoring the bottom layer of a soft coating. These materials are elastic and act as an additional barrier against the cold.
It is better to create the top layer of coating when repairing a soft roof from uniflex, isoplast, isoelast or linocrom. With any of the listed materials, the roofing carpet will acquire special strength and last more than 10 years.
Different materials are used as the first and second layers of soft roofing
It is better to treat the finishing layer of the roofing with hot bitumen-polymer mastic.
Hot mastic is prepared in a cauldron. Bitumen is used as the main ingredient. As soon as it heats up to 200 degrees, filler is slowly poured into it. The main thing is that when mixing the components, the temperature of the composition does not drop below 160 degrees, otherwise the mastic will turn out to be of low quality. The heated bitumen is poured into gasoline, then thoroughly mixed with a wooden stick and used immediately.
For repair inner layers roofing mastic is used cold.
The cold composition is prepared by mixing one part of the filler with two parts of bitumen heated to 180 degrees, and gasoline in the same volume. The components are connected to each other after waiting until all the water comes out of the bitumen in the form of steam. The finished mass is not used until it has cooled.
To treat the finishing layers of a soft roof, bitumen mastic is used, which can be purchased ready-made or made independently
In order to efficiently eliminate defects on soft roofing carpet, you must act strictly according to the instructions.
When the roofing carpet is torn, proceed as follows:
It will be possible to make a good joint again between two panels of soft covering if you take the following measures:
It is preferable to deal with swelling on a soft roof like this:
When rotting a soft roof, perform the following work:
If the soft covering lags behind the base, which usually occurs due to insufficient heating of the lower layer of the roof or laying the material on a dirty surface, proceed as follows:
Measures for major repairs of roofing carpet are determined by the type of material that is planned to be used.
Taking advantage of full recovery soft roofing with roofing felt, do the following:
The author of the article strongly recommends laying roofing felt using four hands. One person should be charged with working the burner on the inside of the material, and another person should be responsible for rolling out and pressing the panels to the base. If you are alone, it will be difficult to perform two complex actions at the same time. In this situation, there is a big risk of moving from a flat line.
If it is necessary to completely replace the soft roof covering with bikrost, the procedure is the same as when laying roofing felt. The only difference: during work they do not use mastic - thanks to the special composition, bikrost, heated by a gas burner, sticks on its own.
Bikrost is glued to the base of the roof without using mastic
To properly cover a roof with bicrost, you need to know the following:
Restoring the roof with profiled sheets is carried out in stages:
Trying to do anything with a soft roof in the cold season is almost a crime. You should not refuse to repair the roofing carpet in winter only if there are serious reasons for this.
Emergency repairs of a soft roof, regardless of air temperature, are undertaken when the roof begins to leak heavily, having been damaged by a heavy object falling on it. The reason for urgent restoration of the roofing carpet may also be the deflection of the covering as a result of the pressure of a large layer of snow or the formation of leaks due to a thaw.
When repairing a soft roof in winter, you must follow the following rules:
To insure a soft roof against deformation and other damage, the following measures must be taken:
Caring for a soft roof in winter is very specific, as it involves performing tasks such as:
In summer, the requirements for the operation of a soft roof are significantly simplified. In order to preserve the original appearance of the coating, it is enough to do only two things:
If you are not late with repairs and adhere to operating requirements, the soft roof will last no less than what its manufacturer indicated. In this matter, it is important to make it a rule that the rolled coating must be inspected as often as possible.
When choosing a material for roofing, we are guided by three main criteria: price, service life, convenience (so that it is not only warm and dry, but also less noise during rain or during the ripening period of acorns and cones). Our task is to balance these three parameters.
Perhaps the most easy solution- roof made of bitumen tiles. Taking into account the price of the material itself, the ease of its installation, the characteristics of flexible tiles are among the best. They are distinguished by good sound/heat insulation, high level resistance to moisture and various atmospheric conditions. This coating does not rot, does not rust, and is resistant to fungi and mold.
The flexibility of bitumen shingles not only allows you to carry out the most daring design projects roof, but also ensures reliable tightness of the joints. Thanks to this quality, it is quite easy and simple to carry out repairs and correct defects that arose during the operation of the building.
If you choose high-quality material and comply with all technological requirements during installation, the bitumen roof will last for many years without causing any worries to its owners. To do this, it is necessary to arrange under-roof ventilation to prevent the formation of condensation. Creating a “roofing cake” with the obligatory use of heat/vapor barrier is also a necessary condition for long-term service of flexible tiles.
The coating itself does not require any special care. Although in winter, during heavy snowfalls, it would be useful to clean the snow with a plastic or wooden shovel, leaving about 10 cm untouched so as not to damage the bitumen layer. In the off-season, if possible, it is advisable to clean the roof of dirt, dust, and debris with water from a hose. This will make it easier to detect minor defects and damage.
Advice. At least once a year, personally inspect your shingle roof for damage or leaks.
If during the inspection the following were found:
Roof repairs and replacements cannot be put off.
In the generally accepted understanding, a leak is water pouring from the ceiling. But it is not always the case. There are roof leaks that we don’t even know about, but which can damage it completely, even to the point of destruction. This is why annual roof inspections are so important. Leaks have different natures:
Advice. A leak is emergency situation in the house. You can't be idle. It is necessary to find a qualified roofer as quickly as possible who will quickly fix the problem.
Repair bitumen roofing performed in dry weather, at air temperatures above +5 ºС. If there are small cracks in the shingles, sealing is carried out. The damaged tile is lifted and lubricated from the inside bitumen sealant. Then you need to press it firmly into place, treat the front part of the damaged area and all joints with adjacent tiles.
If the damage is more severe, one or more tiles will need to be repaired and replaced. To do this, the repair site must be thoroughly cleaned of dust. The tiles of the top row are carefully lifted over the damaged tiles using a metal spatula, holes are cut out under the heads of the fastening nails with a knife, and the defective area is removed. Then the nails are removed using a nail puller lined with a piece of plywood.
Low fat inner side new tiles covered with bitumen sealant, it is inserted into place of the damaged one, under the top row, pressed tightly and secured with nails. All joints of new tiles are covered with sealant. During roof repairs, you need to walk on soft shoes and use ladders wrapped in thick fabric, and safety belts. If traces of moisture are found under damaged tiles, dry the moisture with a torch.
Any roof damage or leakage requires shingle repair. The roof repair itself can be emergency, routine or major. Everything is clear with emergency, but what is the difference between current and overhaul?
If during periodic inspection of the roof defects, damage, or leaks are detected on less than 30% of the roof area, routine repairs are performed. The roof is thoroughly cleaned of dust and dirt; the number of sheets of flexible tiles that need to be repaired and replaced is calculated; the full scope of work is determined.
To reduce the cost of ongoing repairs or in case the tiles of flexible tiles are sintered together, patching can be done. The damaged area is thoroughly cleaned until the shale chips are removed, and a patch of the same material is installed on top of it with an overlap of at least 10 cm.
Advice. For work, choose dry, warm weather(above +5 ºС). During repairs, use light walking shoes and soft shoes.
If more than 50% of the surface is damaged or irreversible changes in the condition of the power structure are detected, major repairs and replacement of the roof are required. Major repairs are carried out in summer in dry weather. The roof is completely cleaned of old covering and substrate. A mandatory step after this should be a complete inspection of the sheathing, the entire strength set, as well as the “roofing pie”. If necessary, defective parts are replaced with new ones.
If the subsequent installation of a roof made of flexible tiles is planned, and under-roof ventilation was not provided on the old roof, it must be done. After tensioning the waterproofing, you need to install a counter-lattice with a ventilation gap of about 50 mm on the sheathing. Then the roof is sheathed with a continuous waterproof decking made of plywood, OSB or dry eurolining, and bitumen shingles are laid on top of the substrate.
When a roof covered with soft roofing materials begins to leak, there is an urgent need for rehabilitation. Sometimes you can get by with patch restoration, which boils down to gluing joints or patching up cracks. And sometimes only labor-intensive and thorough will help.
Before repairs, it is necessary to carefully examine the roof and determine in which places repairs need to be made. Special attention It is necessary to pay attention to the following defects:
After a thorough inspection of the roof, you can determine whether major or minor repairs need to be carried out.
The modern market offers a huge range of roofing roll materials. The most common:
Current repairs are carried out when there are small cracks, loose joints, abrasions and tears on the roof. Usually a patch method is used to repair the coating. Cracks, abrasions and tears are removed as follows:
Broken joints are eliminated in the following sequence:
Repairs to sheet roofing should be carried out after a thorough inspection. If there are multiple areas on the roof where water collects, there are deep scratches and chips in the rolled covering. Tools you may need when fixing your roof:
Advice! It is recommended to use a gas burner as heating equipment, as it will allow the soft bitumen sheet to heat up faster. This greatly simplifies the installation of the coating.
is carried out in several stages:
Repair of a built-up roof is carried out using polymer-bitumen roll coverings And gas burners. Roofs covered with fused materials are practical and affordable. They are monolithic waterproofing panels. The construction of a built-up roof includes the following advantages:
Modern coating of fused rolled roofing is made from polyester, fiberglass, fiberglass and bitumen modifiers.
Repair of soft roofing using fused materials
Repair work to restore flexible roofing is carried out extremely rarely. After all, the guaranteed service life of membrane roofs is 35 years. The biggest advantage This material is resistant to sudden temperature changes. The roofing membrane is a polymer that consists of fiberglass, a plasticizer and modified bitumen.
Today, the following methods for producing flexible membranes are used:
Important!Advantages: resistance to ultraviolet radiation, fire resistance.Disadvantages: the color fades, the material is not resistant to oils, solvents and bitumen components.
Repair of membrane roofing is carried out in one of the following ways:
Repair of seams is carried out by welding; however, welding old and new material without special equipment is quite problematic. Therefore, during repairs, it is recommended to use a chemical method of connecting membranes. This method of joining fabrics allows you to produce renovation work in any season.
Repair of bitumen roofing is carried out in the following stages:
Roofing felt roofing repairs are carried out seasonally. This material is most often used in the construction of buildings and structures with flat roofs, requiring constant inspection by technical personnel, which leads to additional wear. Roof felt roofing is repaired in spring or summer. In winter, it is impossible to replace the roll material. Major repairs are carried out in the spring, since after the winter season all damage and leaks are noticeable. Specialists carefully inspect it, find places of damage, carefully clean the surface of the old coating and begin installing new roll material.
Bikrost consists of fiberglass, on top and bottom of which a bitumen composition is applied. Bicrost is good for protecting the roof from moisture. Bicrost also allows you to replace another roofing felt coating during repairs. The roof is covered with bicrost from the bottom up. It is often used as waterproofing material under bitumen or membrane roofing. Just like bitumen sheeting, roof covering with bicrost occurs in several stages. The service life of this material is 5 years.
Due to mechanical damage, poor installation or improper use roofs, due to the fact that the service life of the roofing covering has expired, leaks may begin. In all these cases, repair of the soft roof, partial or complete, is necessary.
If you do not intend to carry out repairs yourself, you can entrust this work to specialists who will already thoroughly examine your roof. To get started, you need a well-written technical specification.
Terms of reference for major repairs of a soft roof may include:
Based on the results of assessing the condition of the roof, a technological map for repairing a soft roof is left, which includes:
In a private country house, the decision on the need for repairs is made by the owners. If they invite professional builders, a contract is drawn up for the repair of soft roofs. Prices for soft roof repairs depend on its complexity and pricing policy contractor.
If the damage is not that significant, you can repair the soft roof yourself.
Attention! Regardless of the covering - rolls, tiles - it is impossible to repair a soft roof in the rain. Bituminous materials absolutely sealed, water will remain between the layers. Repairs need to be made in dry weather.
Materials for repairing soft roofs:
In case of local damage, it is not necessary to dismantle the entire coating; you can limit yourself to individual areas. Methods for repairing soft roofs if the defects are minor:
Cracks in the coating are treated in the same way.
Another option for restoring a roof in case of local damage is to repair the roof with bitumen mastic. For example, the edge of the rolled material extending from the wall at the junction with the parapet or roofing structure, after drying, is treated with mastic and glued back. Mastic treatment can be used if the defects do not require drying.
For minor repairs Cold applied bitumen roofing mastic is suitable. You can use hot water too, but the repair will be more energy-intensive and you will have to take measures to ensure fire safety.
If the old coating is completely worn out, it is completely re-covered. They dismantle and lay new ones. In this case, you will need special equipment for repairing soft roofs - a gas burner.
After dismantling the covering, the condition of the screed should be assessed. Few and shallow cracks are smoothed with cement-sand mortar. In case of serious damage, re-fill the screed.
How to lay a new coating:
In the same way, you can repair the soft roof of a garage yourself.
Garage roofs are usually covered with roofing felt. You can also use stekloizol, steklobit, bikrost. Ruberoid is placed on heated mastic. The materials to be deposited are laid as described above.
Attention! Place gasoline cans, rags and all necessary fuels beyond the reach of the burner.
As with flat roofs, repairs tiled roofs can be of varying degrees of complexity:
Capital may consist of:
May also require cleaning and restoration drainage systems, repair of other roofing structures.
Price square meter When repairing a soft roof, it depends on the type of repair (current, major), its complexity, area and architecture of the roof.
I present to your attention the approximate cost of installation and repair of a soft roof:
Well, in conclusion, I want to give advice that it is best to trust the device and repair roofing to people who know their business well.
