Abstract: A roofing materials removal device provides a guide system which secures the device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while supported. The removal device comprises a light-weight, durable, wheel supported frame, dual handles for leverage, an electric motor positioned low on the frame to give the device balance and stability. An angled blade reciprocating and riding on linear bearings is connected to spring-mounted tension bars. As the springs force the rear end of the tension bar upward, the forward end of the tension bars pivot downward causing the serrated, leading edge of the blade to slide between the roof covering material and the roof deck. The blade follows the contour of the roof deck dislodging roofing material including nails, roofing felt and shingles. The guide system is positioned on the opposite side of the roof ridge from the removal device.

Abstract: My invention comprises a powered apparatus for detaching and stripping shingles from a building roof and may be used in any direction. A shovel-like device with a blade with nail body engagement slots at the front end and powered means to lower and raise the blade is mounted on a frame. When the blade is in the lowered position, it is moved under the shingles. Then the blade is raised to exert leverage and to detach the shingles while the slots in the blade engage nail bodies, press upward against the nail heads and pull out the nails. As the apparatus is rocked in a forward direction, the shingles, with the nails attached, are stripped by the blade and pushed off the roof or stacked in a pile. My invention can be operated by unskilled personnel in any bodily position and makes a slow, difficult and tiresome job easy by exerting substantial leverage sufficient to remove many layers of shingles.

Abstract: A primary elongated handle conforms to the shape of the hand of the user and is provided with a blade protruding beyond one end. Equal lateral protrusions of the body of the primary handle at the blade end give the tool an overall "T" shape. Within the protruding portion, perpendicular to the primary handle, a half-cylindrical concavity houses a matching half-cylindrical blade. A straight blade edge, longitudinally and laterally protruding beyond the handle periphery and raked indentations of the front corners of the primary handle combine to permit complete access of the blade into corners and intersecting work surface edges. A nut and bolt through the handle and through a slot in the blade permits adjustment by rotation of blade angle and extension. A narrow central portion and lateral extensions of the primary handle toward the ends create a fulcrum effect for optimum force application and balance.
