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.
Claims8
A light weight bitumen roofing membrane with improved sealing properties for adhesion to a roof substrate, wherein said roofing membrane has the form of long sheets and is adapted to be applied to said roofing substrate by overlapping approximately 3 to 4 inches along the sides of the sheets and approximately 4 to 6 inches along the ends of the sheets to form a water tight seal, said bitumen roofing membrane comprising
- a bitumen roofing sheet comprising a felt reinforcement saturated and coated with bitumen, said bitumen roofing sheet having an outer surface and an inner surface;
- an exposed roofing surface comprising fine quartzite particles coated with a colored ceramic coating said particles being in the range of about 30 to 50 U.S. Sieve Size adhered to said outer surface;
- and
- adhesion means applied to said inner surface for adhering said bitumen roofing membrane to a roof substrate.
