How to fix a leaking roof
A leaky roof with signs of leaks is not a reason for despondency and counting the upcoming expenses for major reconstruction. You should not relax either, because the consequences of even a minor defect can result in an impressive damage to the decoration of the house and property. Dampness is the enemy of the wooden truss system and the electrical wiring passing through the attic, the proximity of moisture with which is really dangerous.
Therefore, at the first signs of wetting of the walls and ceiling, it is necessary to immediately take measures to eliminate them. In a number of "current" cases, the owner of the house can successfully repair the roof with his own hand.
Leaks are a clear sign of a violation in the work of the roofing system. This is a characteristic indicator of the occurrence of an emergency situation, regardless of the degree of wetting of building structures.
You can not leave even a minor leak without the owner's attention, which will definitely increase over time. It is necessary to deal with roof defects in a timely manner.
The list of causes of roof leakage is quite extensive. There are prerequisites in it for capital alterations, and for cosmetic repairs that are quite affordable for a home master. It is desirable to entrust the capital restoration to a construction organization. It will be required if there are errors in the design and the defect of the roof structure, such as:
The factors that signal the need for capital intervention also include the use of low-quality materials and fasteners, caused most often by a banal desire to save money.
The cause of roof leaks can be flaws not only in the roof project, but also in the house as a whole. Unaccounted for movements of the foundation or natural instability of wooden walls, for example, can cause a distortion of the roof structure. As a result, there is a violation of the tightness of the joints, displacement of nodes, the appearance of cracks, rupture and destruction of the roofing material.
In addition to serious errors in the design, there are standard reasons for leaks, which can be eliminated by cosmetic repairs of the roof: roofs must be constantly maintained by analogy with all building structures. To do this, it is not necessary to contact builders or be a roofer "from birth". You can cope on your own, if you only have to:
A home craftsman can eliminate minor defects of bitumen and polymer rolled roofing materials. The simplest operations for the restoration of roofs covered with sheet metal and metal tiles are quite accessible. Special difficulties will not cause self-repair of tile and slate roofs, if you know the technological subtleties of working with the listed types of coatings. An important circumstance is the exact determination of the cause and location of the leak.
Focusing on the time and frequency of the appearance of leaks, roofing theorists divide them into three categories, these are:
The first type of leaks is most often encountered by owners who have decided to repair their own roof with their own hands. In most cases, their actions are to restore the roofing. The second type requires thorough cleaning or repair of the drainage system, the third requires recalculation of the thickness of the thermal insulation with major alterations.
The first step to completing a successful repair will be a detailed revision of the condition of the roof system. Visual inspection in most of the simplest cases allows you to identify leaks and find damaged areas. However, it is suitable only for determining the defects of the outer layers of the roofing pie. Violations inside the multilayer filling can only be found by an experienced master.
Diagnostics should be carried out in two stages:
It is wonderful if, as a result of research, it turns out that the roof was leaking due to the banal stagnation of water due to clogging of drainage channels and funnels. This happens because none of the finishing roofing coatings has one hundred percent waterproofing properties yet. All the work will consist in cleaning the water drainage routes and repairing their leaky parts.
It may be necessary to install a tin gutter in the ends of a soft roof, for example, if the waterproofing carpet used for their arrangement does not cope with the duties. It is possible that an easy revision of the drainage and ventilation system will be required by installing protective nets on gutters, blowouts, funnels.
If mosses are found on the roof, they must be carefully removed from the coating. You can only clean bitumen and polymer roofs with a broom. With similar care, they treat profiled flooring and metal tiles with a polymer coating, because it is easy to scratch and make it unusable. But a steel, copper or aluminum roof without a protective and decorative outer shell can be cleaned with a wooden shovel, but without fanaticism.
The most favorable period for carrying out repair operations on the roof is recognized as early spring or autumn. They are favorable because of the temperature that is conducive to work in the range from +5 ° C to +15-18 ° C. In general, it is not recommended to engage in capital or current repairs of any kind of soft roof, if the temperature on the thermometer is below the specified lower limit. Both bitumen and polymer material then loses elasticity, cracks, it is almost impossible to attach it evenly to the base.
Metal, asbestos-cement and ceramic coatings are not so demanding to the temperature regime, but it is much more difficult to work with them when the thermometer is negative.
Naturally, from the point of view of optimal working conditions, liquid precipitation is undesirable. Masters will be able to protect the awning from their impact, but excess humidity in some cases negatively affects repair procedures. It is difficult to achieve an ideal result of the adhesive operation, it is impossible to predict the result of applying the solution to cracks, etc.
Since some restrictions on carrying out repair work on the roof still exist, it is desirable to have "improvised" material in stock all year round. To apply a temporary patch to the roof, regardless of the type of coating, it would be good to replenish the farm with a piece of roofing material, roofing material, polymer membrane or similar insulating material.
And at the same time with glue or bitumen mastic, no matter cold or hot, necessary for gluing a temporary repair device. It does not hurt to stock up on a piece of roofing tin.
Based on the results of a preliminary survey, it can be concluded whether an independent repair is available to a home master or it is better to hire roofers. For those who have decided to make their own efforts, we offer an analysis of elementary repair operations. Immediately I want to warn you against the persistent desire to restore a steep roof with a cold attic from the outside.
It is not always advisable for owners of buildings with such a design to take risks by climbing on ramps. If it is possible to replace the piece element of the coating from the attic, it would be wiser to take advantage of this significant advantage.
The indisputable advantage of flexible tiles is the ability to change only damaged tiles, without disassembling the vertical or horizontal row to the damaged place. Cracks, holes and notches on it appear most often when cleaning snow in frosts with a hard shovel or from falling heavy objects in the heat.
If the sprinkling just fell off the surface, you should contact the manufacturer to replace it. It is quite difficult to imagine cracks of a piece element as a warranty case. After a lengthy debate, you will still have to change the damaged shingles yourself.
The sequence of works on the replacement of bitumen shingles:
If the bitumen shingles are laid on low, almost flat slopes, it will not flow due to mechanical damage. In such situations, it is recommended to completely replace the finishing roofing, because it is not compatible with the type of construction.
Repair of bitumen, bitumen-polymer and polymer roofing is carried out by installing patches of a similar material or from a glass mesh with subsequent application of mastic. Patches are applied only on top of the gaps in the polymer membranes.
The cover plate intended for repair should cover the damage by at least 5 cm in all directions. The edges of the patch are rounded off. In order to create a strong connection, it is better to weld a piece of the membrane, but you can also glue it to a composition with a compatible formula.
The method of repairing rolled bitumen and bitumen-polymer roofs depends on the type of base: A
soft roof that is broken or bubbling in many places should not be repaired with patches, it is better to completely cover the strip or the entire carpet.
A roof covered with sheet metal can leak for three reasons, these are:
With the flow of standing seam seams, they fight either with the help of an edge bending machine, or artistically with the help of a hammer and a utility bar. It is easier to seal the recumbent fold with fiberglass and cover the repaired place with polymer mastic.
Small holes and rusted holes can be patched up like this:
If there are more than two or three holes on the metal roof with significant damage over the entire area of a sheet or a pair of sheets connected to a map, they are completely changed. A single noticeable hole in the metal is sealed by duplicating a part of the sheet. This can be done if the edges of the repair pad can be inserted into the standing folds. Jewelry work, it is better not to take it without experience.
There are three common reasons for metal-tile coating leaks, these are:
The first point is related to major alterations. You can correct the situation on the second point yourself. If the sealing washers of poor-quality fasteners have collapsed from temperature fluctuations, it is necessary to act according to the following algorithm:
Single small holes are patched according to the standard scheme of repairing a metal roof. It is better to completely change the sheets with multiple holes, acting in the same way as when replacing fasteners.
