Abstract
Abstract A tool, primarily for use in stripping asphalt and wood shingles from a roof, has a flat base plate the front edge of which is provided with a transverse series of teeth and which includes a rearwardly and upwardly extending portion providing a transverse fulcrum. A handle is anchored to the handle and includes a portion spanning the fulcrum zones and anchored to the base plate adjacent the teeth. The handle defines with the base plate an included angle such and the length of which and the shape of which is such that the user can readily force the base plate under a group of shingles and pry them, together with nails, from the roof easily and safely while working from a nearly erect, comfortable position whether the shingles are to be stripped starting from the top of the roof, the eaves, or working from side-to-side of the roof.
