Embodiments of the invention described herein pertain to a pneumatically powered shingle removing apparatus. The shingle removing apparatus includes a frame having a first end and a second end. A first pneumatic cylinder assembly is mounted adjacent the first end of the frame and a second pneumatic cylinder assembly is mounted adjacent the second end of the frame. The first pneumatic cylinder and the second pneumatic cylinder extend substantially parallel from the frame and each have a chisel extending at least partially from the respective first pneumatic cylinder assembly and the second pneumatic cylinder assembly, the chisels being moveable back and forth from a forward position. A stripping blade is attached to a front end of the chisels of the first pneumatic cylinder assembly and the second pneumatic cylinder assembly. A first air conduit delivers pressurized air to the first pneumatic cylinder assembly and a second air conduit delivers pressurized air to the second pneumatic cylinder assembly. The pressurized air moves the chisels of the first pneumatic cylinder assembly and the second pneumatic cylinder assembly back and forth from the forward position thereby forcing the stripping blade to move in a reciprocating motion for removing shingles from a roof. |
