Abstract
A roofing plate for securing a roofing membrane to a roof includes a top surface, a bottom surface and a generally oblong peripheral edge having two major sides and two minor sides. An opening is located generally centrally on the plate in a central portion for receiving a fastener for securing the plate to the roof, and a plurality of gripping formations are formed on the peripheral edge for preventing slippage of the roofing membrane relative to the plate. Also included are a pair of first rib portions which project from the top surface respectively along at least each of the two major sides between the peripheral edge and the central opening, and a pair of transverse ribs which project from the top surface for enhancing torsional stability and reinforcing the central portion of the plate.
