ABSTRACT:
A holddown to be used in conjunction with a headed fastener, a roofing system and a method utilizing the same. The holddown comprises a disc-shaped spring and a body encasing the spring. The fastener is interpositionable within a hole in the body of the holddown and displacement of the fastener applies a compressive force to the holddown. The spring is deformable from an unbiased position to a biased postion by the compressive force. The body is deformable from an unconstrained shape to a constrained shape by the deformation of the spring. The holddown is usable in conjunction with both the fastener and pliant filler to affix roofing material in a watertight relationship to a roof structure and to maintain the same in position against the forces applied by the wind.
