Abstract
A roofing material and roofing fastener removal tool. The tool comprises a handle attached to a blade. In the preferred embodiment, the handle is adjustable relative to the blade. In this embodiment, a portion of an adjustment assembly provides additional pivot points to extend the working range of the blade. The blade includes two rows of material engagement portions. The rows include large teeth and small teeth spaced evenly and regularly along the working edge of the blade. The larger teeth are thinned and rounded to facilitate insertion between roofing material and a structure, while the smaller teeth are thinned on one side only and rounded to facilitate insertion and engagement with roofing material and roofing fasteners. The teeth are separated from each other by tapered slots which are sized to engage shanks of roofing fasteners.
