Despite abundance in the construction market of modern materials, the popularity of roofing material does not decrease for already several decades. Scope of roofing material is quite extensive: roof device, insulation of foundation, walls. But life cycle of material depends on many factors.
The fundamental factors influencing life cycle of coverings
Those who are going to build the house or to make major repair, interests question: whether the roof covered with roofing material, 30-40 years can stay? Experts assure that there are all bases to claim that at observance of some rules and norms the roof is capable to serve several decades. For this purpose it is necessary:

Even small dents can become the reason of damage of covering and owing to what reduction of life cycle of roofing material. Community services recommends to perform inspection of roof periodically. Prevention will cost cheaper, than replacement of covering.
Types of roofing material
In modern construction fiber glass roofing material is very often used. Minimum life cycle of this synthetic material of 12-15 years.

Polymers and bitumen which are practically not exposed to rotting or decomposition are part of material. Novelty in the market of roofing materials is self-adhesive roofing material. When laying material the heating of base layer is not required. To forget about roof problems for about 20-25 years, it is better to prefer expensive materials to cheap. Low-quality roofing material should be changed nearly every year. One more kind of roofing material is roofing felt. It, as well as other types of roofing material, differs in rather long life cycle. Distinguish roofing material of the first generation on cardboard basis, the second generation: rubemast, thicker layer of bitumen having in comparison with other types of roofing material, the third - with synthetic basis.
