Abstract

The invention herein is a roofing fastener with integrated swivel means on the upper part to facilitate the process of affixing rectangularly shaped sheets of rubber roofing material to the upper surface of a roof. Specifically, the invention is a longitudinally disposed fastening member in the general form of a screw or nail-like member which is adapted to be inserted through the upper surface of the rubber roofing sheets and thence through the upper surface of the roof structure, serving thereby to anchor the rubber roofing sheets to the fixed roof structure. The fastening device may optionally have a longitudinally extending centrally located chamber which is co-axially aligned with the longitudinal central axis of the fastening member, and this chamber has a plurality of laterally disposed openings which extend from the chamber to the outer surface of the fastening member, said chamber being adapted to receive a liquid sealant at an opening in the upper surface and disperse same through such lateral openings. On the upper portion of the longitudinally disposed fastening member is a circular cap member which is eccentrically disposed about a semispherical configuration on the lower part of the head member, so that the cap member can swivel about such head.
