Abstract
Shingle simulating laminated flat strip sheet material for application in horizontally extending weatherproof interlocked courses, comprising a thin, flexible underlying plastic base sheet having a self sealing asphalt mastic coating layer and a mineral granule front surface layer. The strip material has on each of its opposite faces a longitudinally extending groove adjacent to and spaced from opposite ones of its longitudinally extending edges, so that the strip material is foldable along the grooves around the edge of an adjacent folded strip edge.
