  • Patent number: 6318213
    Abstract: A tool primarily for use in stripping asphalt and wood shingles from a roof consisting of a blade, a body, and a handle. The blade has a wide forward portion with front serrate edge, transverse bends for rigidity, and primary fulcrum. The novel and unique front edge is curved to accommodate sags in the underlying roof and to facilitate insertion under shingles. The body is attached firmly to the blade and contains an upper portion to receive an elongated handle and an undercarriage curved in the vertical longitudinal plane providing a variable mechanical force ratio as the operator uses the tool to remove the roof shingles by vertical travel of the handle. For shingle removal, the front edge of the blade is slid or pushed under shingles and the handle lowered toward the roof surface.
