The most important problem of the roof is leaks. There are various types of leaks in accordance with the time of their appearance. They can form immediately after precipitation, with poorly made roofing operations or in the presence of mechanical defects in the roofing material. If cracks appeared on the parapet adjacence or the funnels were made incorrectly, then the roof will stand before the rain, but in the case of a large amount of snow, it will leak. The hardest thing to get rid of “flickering” leaks. This kind of leaks appear in the roof, which has a large number of microcracks, incorrectly made parapets or short aprons. The roof will not last you long if the rules and construction norms were violated during its construction. In addition, the correct calculation of the design of the roof and high -quality roofing materials will be required.
The flowing roof is a very common and urgent problem. Before starting roofing, you should disassemble the old roof. Of course, this will cause additional costs. But in the end, you will receive better work with a long warranty period.
For the construction of a new roof, not only roofing materials are needed, but also a flat, leveling screed equipped with a slope for water flow. The screed should not have any recesses! Microcracks must be closed with a primer.
Well -executed ground work make it possible to securely fix the first layer. As a rule, on the old roof there are several layers of bitumen and roofing material containing a large amount of rainwater. Such a heavy coating harms the roofing base. That is, if you build a new roof over the old, all the moisture will remain inside and the base will be destroyed. This is why experts recommend getting rid of the old roof covering.
