Abstract: A shingle unit used for covering the hip, ridge and rake portions of an asphalt shingle roof. The shingle unit includes a top cover permanently bonded to a tapered substrate to create the visual effect of tapered thickness. The shingle is preformed to an inverted, V-shape so as to conform to the hip, ridge or rake portions of a roof. Various notches are formed on the perimeter of the top cover to facilitate longitudinal alignment and surface exposure of the shingles at installation. Depressions are formed on bottom surface of the substrate and are filled with an adhesive during manufacture. After installation, solar heat causes the adhesive to flow between the substrate and the subjacent area of the top cover, or roof, to provide wind uplift resistance.
