This heavyweight shingle is composed of a resilient, inorganic glass base that is coated and permeated with additional weather-resistant asphalt. As a perforated, three-piece, pre-tapered hip and ridge shingle, it provides the assurance of long-lasting performance and is surfaced with ceramic colored granules, which protect the asphalt from ultraviolet radiation. Special algae-inhibiting granules have been added to provide long-lasting algae resistance. Each shingle has release tape and mineral powder applied to the underside, thus preventing any sticking in the bundle. This shingle meets ASTM D3018, ASTM D3161 Class F, ASTM D3462, and ASTM E108 Class A, shingle compositional and performance characteristics, and is suitable for installation as a capping shingle with any of our complete line of asphalt shingles.
