A primary protective layer of underlayment is one of the most important components of a properly constructed asphalt shingle roofing system. The PermaShield synthetic underlayment is designed to be installed beneath asphalt shingles. It has earned the designation of ENFINITY Integrated Roofing Accessories. It’s a less expensive alternative to #15 asphalt saturated felt paper.
Due to its light weight, it is simple to mount even in cold weather. PermaShield is the ideal blend of toughness and pliability. Shingles aren’t the only thing that protects you; anything beneath them does, too. The underlayment is an essential part of this roof structure. A roof’s underlayment is a waterproof and water-resistant membrane that is built between the shingles and the wooden deck. The installation of an underlayment is needed because it provides an additional layer of protection against extreme weather conditions. A shingle roof structure without an underlayment is not protected by the manufacturer’s warranty.
