Abstract
Abstract A novel method of repairing shingle roofs and a versatile roofing tool for use in such a method is disclosed. The method involves removing individual, defective composition or wood shingles and replacing them with a rigid shingle, such as a metal plate. A roofer''s hammer having a hammer head at one end and a claw at the other end of a handle having a gradual compound curve near the midlength of the handle is particularly useful for this purpose. It is used by slipping the claw under shingles immediately above the defective shingle until it reaches the nail near the far edge of the shingle. The claw is engaged with said nail and the head of the hammer is forced downward to extract said nail. A metal plate is engaged in a clip alongside said hammer head. The plate is then forced into the space left by the removed shingle.
