Abstract
A hand tool for removing roofing shingles and nails. The tool has a head attached to an elongated handle. The head has a wedge-shaped cross profile. The head is comprised of a plurality of identical, parallel blades, having a relatively flat, pointed leading edge adapted to be removed. The blade leading edge rises in vertical height to a trailing edge. The trailing edge is connected to a handle. Spacers are attached between the blades to form spacing between blades sufficient to trap any roofing nails holding a shingle to an underlying roof sheath.
