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.
