Abstract
Abstract A roofer's tool for stripping shingles from the roof of a building; the tool including a blade attached to a straight handle by a mounting bracket whereas the mounting bracket includes a section attached to the end of the handle and a fulcrum portion extending backwardly from the handle while a flat attaching section protrudes forwardly from the lower end of the handle and where the blade has a row of operative teeth along a front edge thereof whereby the tool can be manually forced under a layer of shingles and an effective prying action upwardly on the shingles from their lower surfaces can be provided by pivoting the tool around a fulcrum section of the mounting bracket. Also the blade is removably attached to a portion of the mounting bracket by mounting members which are readily accessible and are protected against damage in use of the tool.
