Abstract: Fine quartzite particles with a colored ceramic coating are used for surfacing roofing membranes to enable easier lapping of the roofing membranes while still maintaining necessary UV and heat protection. The roofing membranes may include modified and unmodified bitumen compositions that may be applied to roofing surfaces using heat welding, hot asphalt, cold adhesive, self adhesion and the like.

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.
