It is known that residents of the upper floors of houses can face the problem of leaking roofs, and it's simply unpleasant to live in the conditions of the blotting roof of a private house. Leakage of the roof of the house will lead to the formation of dampness and the appearance of spots that grow into a terrible fungus. Naturally, any developer in the event of a leak, makes maximum efforts to eliminate it, trying to discover the cause and nature of the phenomenon.

Types of roof leaks
The type of roof leakage depends on the type of seasonal precipitation, so they are distinguished for rain, snow and leakage flickers, not associated with precipitation.
Let us say that the main reason for the appearance of any type of leakage is deformation of the roofing foundation, which caused the opening of the joints, the formation of fractures of any degree of opening and shrinkage of the joints. This process is typical for flat roofs with stagnant water and sediments.
Rainwater leakage occur after rainfall, therefore it is necessary to prevent this type of leakage at the end of precipitation.
Snow leaks arise directly in the process of melting snow in the spring on the roof. In the process of melting snow includes the formation of ice that blocks the natural drainage of thawed water, snow leaks are especially relevant in the case of improper operation of the drainage system.
Shimmering leakage type is not associated with precipitation, but depends on the presence of microcracks in the roofing, creating a wetting of the insulation and roofing carpet, as well as the reasons for the violation of the laying technology - a small width of the protective structures of aprons and umbrellas, raindrops, poor parapet laying.
Roof covering, types
The type of roofing, which is affected by the destruction of the roof, is the starting point of the cause of leakage. There is no doubt that soft ruberoid roll materials are short-lived. More reliable material is rolled coatings, which have a polymer component.
The polymer component in the form of glass fiber provides the plasticity, and the multi-layered construction of the roofing cake - quality. The most promising roofing coatings are bitumen-polymer materials with non-rotting base - mastics and membranes.
roofing mastics and membranes
Roofing mastics are dispersive materials with a certain type of binding filler: bitumen-polymer, rubber bituminous and bituminous. To create a roofing coat mastic used fibrous and powdered fillers with a certain degree of heat resistance. The expediency of using waterproofing mastics is described in http://svouimirukami.ru/articles/chto-takoe-krovelnaya-mastika-pravila-naneseniya-krovelnoj-mastiki.html
However, before using any roofing, it does not hurt to understand the cause of leaks.
But special respect for developers who care about the integrity of the roof, use roofing membranes - single or multi-layer, laid on the roof self-adhesive layer.
Why there are leaks of the roof
The reasons for the occurrence of the phenomenon are leakage, and it is difficult to simulate the process. Any roofing covering, ideally, should provide a continuous waterproofing. If the technology of tightness of the roofing and space is compromised, and if mistakes are made, the "problematic" places of the roof can be safely called the accelerator of the leakage formation process.
problematic places of the roof
The problem roof elements are the places where the roof joins the pipes and walls, parapets and other vertical structures, as well as in the valleys. The causes of leaks are:
- depressurization of vertical joints of joints
- mechanical damage to the integrity of the coating.
Causes and problem areas of the roof can cause large-scale leaks and emergency situations. A timely question arises: "How to detect a roof leak in time."
Helpful Tips
The accuracy of the diagnosis of leakage studies can not be imagined without special equipment - an infrared scanning camera, which clearly shows the technical condition of the roof and its elements in the study. The analysis of the obtained data and the detected leaks of rafters, hydro and thermal insulation will determine the nature of the leakage and the volume of restoration and repair work.
Ways to eliminate roof leaks
The process of eliminating leaks begins with a survey of the roof.
roof inspection
The initial visual inspection of the roof is made from the inside in order to detect visible defects in the ceiling and damage assessment.
With insignificant leakage, the roof and roof space are inspected from the attic, checking the condition of the rafters, electrical wiring and floor.
Then they go to the outer roof research, beginning with the skate element, its integrity and waterproofing and going down. Particular attention should be paid to examining the valley, the lower layer of the cover and the cornice board. It is recommended to identify holes, dents, chipped and swollen.
Having specified all the revealed defects of a roof and water drains it is possible to start their elimination.
Helpful Tips
Recall that experts can provide technical assessment of leakage. Based on the act of inspection, an expert conclusion and recommendations for choosing a method for repairing different types of roofing are made.
ways to repair a tiled roof
The most common cause of tile roof leaks are cracks on the tiles, rupture of waterproofing between the slats in the tile fixing areas. A problematic place is the roof overhang and the place of docking with the pipes. Solution: removal of old waterproofing and destroyed tiles. Strengthening of tile fixing points.
repair of metal
The main mistake that entailed the leaks in the metal roof was considered bad fixing screws, mechanical damage during cleaning and the presence of a gap between the mounting parts. Problem places - the molding element and the destruction of the rubber washers of the self-tapping screw.

water drain repair
Inoperative drainage may occur due to depressurization of the connections, change in the level of the trough slope, clogging the drainage line and the formation of cracks at the neck or icing.
