ABSTRACT:
A roofing fastener is shown adapted to fasten membrane roofing film to roofing structures. The fastener comprises a base plate having a segmented upper, tapered circular flange section; a segmented middle circular ring locking section; and a lower base section. After attaching the base plate to the roofing structure by means of a fastener inserted through an axial hole located in the center of the base plate, and an annular snap ring having an internal diameter just large enough to fit over the film covered base plate when the segments of the base plate are compressed, is forced over the film covered base plate, and adjacent to the locking section, thereby locking the roofing film in place.
