  • Patent number: 7313985
    Abstract: In the past shingles and nails were removed from a roof by means of a shovel, pitch fork, or shingle removal tool. All of these methods require intense physical labor, and because of the small width of the available tools are very time consuming to achieve the desired results. The Rapid Roof Remover alleviates the need for intense physical labor by levering the shingles and nails from the wood they are attached to by the action of the tear-off blade (up to 36 inches in width) being levered back by the pneumatic cylinder.
