Previously, the standard solution for flat roofing in Asheville was roofing felt. Its service life was limited to two years, after which the roof began to leak. Modern coatings are much more reliable. For example, liquid rubber coating hardens instantly, forms a seamless surface and has excellent adhesion to any materials.
Standard roof waterproofing, when viewed from the inside, consists of the following layers: OSB board, vapor barrier layer, non-combustible insulation, waterproofing membrane, sheathing, roofing material. In this case, the insulation is protected from condensation on one side, and from precipitation on the other. The only drawback of this technology is that the waterproofing membrane is located directly under the roofing material, so it can easily be damaged. Most often, this occurs when the installation technology is violated or when purchasing low-quality materials. This situation requires immediate repair , since all the moisture will accumulate in the under-roof space, which in the shortest possible time will lead to the destruction of the entire structure.

For waterproofing in the Asheville region, various films and membranes are used. The matter is not limited to laying this material. The waterproofing process is complex and quite expensive. It implies a complete reworking of the entire roof structure. Only in this case can one expect that the task will be achieved.
Accumulating under the roofing material, moisture has no other way out than to seep into the attic, causing “rain” from the ceiling of the living room. Even if the volume of water is not so large as to cause leaking ceilings, excess moisture under the roof will inevitably lead to damage to the rafter structures.
A leaking roof during seasonal rains and melting snow is a common sight both in multi-story buildings and in private homes. This happens because no roofing material, even the highest quality, is able to provide complete sealing. Small cracks, into which moisture can easily penetrate, remain at the joints of roofing sheets, where the roof adjoins the walls and near pipes.
