Abstract: A metal deck roof repair module system that does not disturb the existing roofing membrane or insulation. The roof repair module has a surface profile similar to that of the existing deck, is installed from below the roof deck, and is jacked into mating position with the bottom surface of the existing roof deck. The repair module comprises two elongated frame angles pre-welded to a piece of corrugated sheet metal. The module is ultimately supported between two adjacent roof beams through support angles which frictionally engage the roof beam. A jacking lever comprised of a handle, an oval-shaped head, and a pin extending from a perimeter of the head, lifts the module to the existing deck by camming against a lower edge of the frame angle. A guide bolt extends through the frame angles and the support angles to prevent lateral movement of the module as it is raised.
