Roofing Materials and Roofing Systems with Improved Fire Resistance and Methods of Making Thereof
This invention, in embodiments, relates to a roll comprising a roofing material. The roofing material includes a substrate having a first side and a second side, and a film layer attached to at least one of the first side or the second side of the substrate, the film layer comprising a polymer and having a thickness of 0.5 mils to 100 mils. A single layer of the roofing material achieves a Class A rating for steep slope roofing systems when tested according to UL 790 and/or ASTM E-108 Standard Test Methods for Fire Tests of Roof Coverings. This invention, in embodiments, further relates to a roofing material and a steep slope roofing system.
