A shingle remover with a reciprocating material stripping assembly removes roofing shingles and nails with reduced effort. The shingle remover has a metal frame carrying an electric motor coupled to a material stripping tooth assembly for driving reciprocation. The stripping assembly teeth form a wedge-like comb movably retained in the frame and driven by connecting rods attached to a counter-shaft by eccentric mounts. The teeth are laterally spaced only slightly more than the width of a nail shank, forming an inclined lifting surface wherein adjacent teeth engage under the head of nails that are encountered as the shingle remover is advanced, and drives the stripping assembly under the nail heads. The combination of the inclined lifting surface and the reciprocating motion of the material stripping assembly remove the roofing material and lift roofing nails straight out of the roof sheathing.
