Abstract
Abstract A manually manipulatable tool which is intended for use in roofing repair, namely, for removing resilient composite roof shingles for replacement. The tool comprises a narrow elongated bowed blade or rocker bed having prying means at its working end, which prying means is adapted to be inserted beneath the free edge of the shingle and to dislodge the nails which hold the shingle to the roof. The tool further comprises a handle on the upper surface of the blade distant from the working end, which tool is meant by its weight and configuration to be held by one hand and used in a natural underhand swing motion of the arm to accomplish dislodgment of the shingle. The handle is equipped with a shield to protect the worker's hand from abrasion, cutting and impact.
