Abstract: A flexible roofing fastener is provided for securing water resistant material to a substrate such as wood and preventing leaks through holes created in the material by the roofing fastener. The roofing fastener includes a resilient disk having a flat lower surface, a thick central region and an annular region having a thickness that tapers downwardly from a central area toward a periphery. The disk central region has a plurality of evenly spaced apart flat-headed nails extending downwardly there through. The annular region having plurality of holes through which sealing material can flow. A flexible disk, when upload flexes in a cup shape causing wedge effect on the anchoring points in the substrate, allowing this fastener to perform better when under a simulated wind uplift testing of various modified bitumen Roof Systems.

Abstract: The present invention provides a roofing fastener, a roofing assembly including the roofing fastener, and a method of installing the roofing fastener into the roofing assembly. The roofing fastener includes a head and a shank integrally connected thereto. The shank and the thread thereon permits the roofing fastener to be self-tapping and threaded into a base substrate such as a concrete deck. Preferably, the roofing fastener includes a polygonal socket within nubbins thereon to squeeze about a drill bit. Also, ideally the head of the roofing fastener is round and has a diameter which is greater than the length of the shank. Ideally, the fastener is made of a low-moisture material which can absorb water from the surrounding substrate causing the fastener to swell and increase its holding power.
