ABSTRACT:
Apparatus for removing fastened roofing material from a roof comprises a frame on which is mounted a vertically reciprocable blade having a leading edge adapted to be accommodated beneath a strip of roofing material. Reciprocal movement of the blade causes roofing material overlying the leading edge to be freed from and lifted off the roof. The frame has supporting wheels and an engine which drives the wheels and lifts the blade. Springs effect downward movement of the lifted blade.
