ABSTRACT:
A method and corresponding apparatus accurately and efficiently fasten roofing materials to a roof. A first stroke of a piston both separates a single roofing screw from a roofing screw magazine and delivers it to a premounting position and separates a metal bracket from a metal bracket magazine and delivers it to a metal bracket premounting position. The second or return stroke places the screw and the metal bracket into respective mounting positions. A power screwdriver screws the screw through the metal bracket and the roofing materials placed on the roof and into the ceiling structure. The apparatus is mounted on a mobile frame to allow easy movement of the apparatus from fastening position to fastening position on the roof.
