Owners of own houses face such problem as course of a roof sooner or later. From a ceiling the rain can dig when necessary, but it happens to a thicket in the fall after plentiful heavy rains or in the spring from the thawing snow.
Roof leakage – quite unpleasant event. Of course, at the timely address of attention to this circumstance the leakage can be eliminated not only quicker, but also without destructive consequences which can turn out if to shelve work. Therefore it is necessary to try to find the leakage reason as soon as possible.
Possible reasons of a leakage
Courses of a roof can be the reason and leaky or low-quality roofing material, and violations in a design of "roofing pie". Most often it occurs when neglect recommendations concerning the size of overlaps, to quality of furring, amount of fixing materials.
The best exit – not to allow leakages in general for what it is recommended to make small preventive repairs of a roof regularly. It can be even just survey of the most problem places that will help to reveal danger of a leakage in due time. Emergence of water on a premises ceiling can not always coincide with the place of course. To understand whether the roof because of violations of integrity of a roofing covering, generally easily proceeds. It is necessary to check, whether on the place fixtures and whether there are no broken covering elements. Even the small opening from the self-tapping screw can be the cause of emergence of damp spots on a ceiling. It is necessary to examine carefully roofing material and fasteners if they tend to corrosion: the site struck with corrosion gradually can lead to big destructions.
Problems with "roofing pie"
If matter in violations of "roofing pie" to remove all covering entirely to detection of the reason of a leak it is unfairly expensive also concerning labor costs not especially well. The reason can try to be defined in a different way. It is the best of all to track the nature of emergence of a leakage. If the leak is found generally in rainy weather, the reason, most likely, in violation of a roofing covering or water flows under the aprons arranged around air vents or pipes of a flue. To eliminate such leakages, it is required to strengthen anew all difficult places on a roof. If emergence of wet spots on a ceiling happens in dry weather - it is "flickering leakages" which turn out because of the becoming wet heater. And it, in turn, occurs because the roof cannot "breathe" as at installation defects were allowed. It is possible to correct only at full analysis of a roof – it is required to establish a membrane or to carry out ventilating gaps. When between "rafter legs" there are wet spots, it is sign that between them the waterproofing is too hardly tense, and the sizes of ventilyatsinny gaps are not observed. At the wrong calculations for installation of rafter designs and a big tension of a waterproofing of movement lead to a rupture of a film. For correction a roof it is necessary to remove and re-make a waterproofing course.
