Abstract
An apparatus for removing shingles and shingle fasteners from a roof. The apparatus comprises a frame and a driver unit coupled to the frame, the driver unit including at least one motor. The apparatus also comprises a stripping unit coupled to the driver unit, the driver unit being operative to alternately move the stripping unit between two positions. The stripping unit is adapted to lift shingles off from a roof and to extract shingle fasteners out of the roof as the stripping unit alternately moves between the two positions and the apparatus moves on the roof. The apparatus further comprises a pair of cutters coupled to the driver unit, the driver unit being operative to drive the pair of cutters. The pair of cutters is adapted to cut shingles lifted off from the roof by the stripping unit to produce a strip of shingle material, the strip of shingle material including at least a portion of a first shingle connected to at least a portion of a second shingle by at least one shingle fastener extracted out of the roof by the stripping unit.
