Abstract
A gripping element for attaching a roofing membrane to a roof includes a generally planar plate having a generally central opening and an oblong peripheral edge. The plate includes a top surface facing away from the roofing membrane, an upwardly projecting rib, and a plurality of gripping formations for preventing slippage of the roofing membrane relative to the plate. Preferably, the central opening is larger in diameter than the diameter of a corresponding shank portion of a threaded fastener so that the plate is permitted a specified amount of rocking when subjected to a membrane uplift force.
