Abstract
The present invention relates to a roofing system employing a combination of silicone rubber layers. The method utilizes a first layer of silicone rubber which is applied directly to the substrate and is then overlaid by a membrane of silicone rubber impregnated fabric. The fabric layer is placed in position before the first layer cures and is then overcoated with a second layer of silicone rubber which serves as a protective outer coating.
