ABSTRACT:
An artificial shingle adapted for mounting on substantially any roof surface (e.g., spaced slat- or solid sheathing-type construction) whereupon conventional shingles might alternatively be mounted, wherein the artificial shingle provides superior cost, wear, fire resistance, weight, or other characteristics while presenting a substantially realistic appearance and resemblance to a natural material (e.g., slate, cedar). The artificial shingle comprises a top surface and a bottom surface. A lower top exposure portion of the top surface and an upper bottom exposure portion of the bottom surface are both provided (e.g., stamped, molded, imprinted) with a relief or three-dimensional pattern substantially resembling the natural material of which conventional shingles are constructed. Other features include a midline groove with a cuttable end tab, and a portion of reduced thickness with strengthening corrugations.
