Patent attributes
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.
