This self-adhering “self-stick” roofing underlayment is composed of a high-grade, reinforced polyester fabric laminated to a high temperature asphalt adhesive system.

PrimeSource Building Products recently was awarded a patent for its innovative design of a synthetic underlayment called ShingleLayment, which the company claims is the only synthetic underlayment in the market designed to protect a roof and look like a shingled rooftop during construction.
