ABSTRACT:
A roofing product is provided that has a release film on the back surface thereof, and the release film is split to allow the material to be flopped back; one side is stuck and then the other side is flopped down. The roofing product includes a top surface having roofing granules thereon and wherein a selvedge is provided along the length of the product for overlapping several of them on the roof. An important aspect of the present invention is that the back surface has a silicone coated 2-section release film. The composition of the roofing product consists of polymer-modified bitumen which makes the product self-adhering. There is a fiberglass reinforcement inside the product. The peel-off film on the back surface of the product consists of two separate strips instead of a single strip or film.
