Waterproofing roofs

Waterproofing is a complex of measures ensuring the protection of designs and structures from water penetration. Waterproofing in roofing work is of paramount importance, since the slightest mistake when constructing a roof can have very serious consequences - even the smallest imperfection will bring all the efforts of waterproofing to zero and will cause nasty leaks and water seepage

Repair of roof - a costly and complicated matter, so it is important initially to provide reliable waterproofing the roof. Materials for waterproofing should be different special properties, mechanical strength, resistance to deformation, resistance to aggressive media, etc.

Waterproofing roofing materials create an impenetrable barrier to atmospheric moisture and precipitation, and along with insulation serve as an important component in the formation of a multilayer roof.

Roofing materials market is constantly expanding and improving, responding to the most stringent requirements for modern building techniques.

To date, the choice of methods and materials for the waterproofing of the roof is very wide. First of all, a classic of bitumen-polymer materials such as roofing material. Improved roofing materials of this type are resistant to rot and longer life, for example, fiberglass or polyester.

Modern waterproofing roofing materials do not necessarily have to be rolled. For example, a good waterproofing can be achieved through a seamless roofing mastic. In this case, mastic - a polymer membrane, which hardens immediately on the surface of the roof. Undoubted merit of the polymer mastic - it's the lack of seams and joints where water seepage occurs most frequently, and hence it provides better waterproofing of the roof.

Widespread found waterproofing roofing film type. Roof waterproofing film can be made on the basis of polyethylene or polypropylene. Special kind of roofing films - so-called superdiffuzionnye membranes, which provide air and removing moisture from the room, but do not let the water out.

Waterproofing film used primarily for covering certain types of pitched roofs of slate and metal.

Waterproofing membrane-type films are used in the device of "warm roof". When installing the diffusion of the membrane can be laid directly on the surface of the insulation, even without the device ventilation gap. This allows more compact use of space underlay. An ideal scope superdiffuzionnyh membranes for waterproofing roofs, this arrangement of warm attics from the cold attic.
