ABSTRACT:
The subject invention is a roofing attachment plate with integrated means to seal and affix such plate on the upper part of a roof surface in order to secure a roof sheet to the upper surface of a roof. Specifically, the invention comprises a circular member on other shaped attachment plate which is adapted to be placed flush on the upper surface of the roof deck with opening means to receive a nail or stud to attach the plate to the roof structure, serving to anchor a roofing sheet to the fixed roof structure. The fastening plate has an upper cup-like chamber that is centrally located on the attachment plate and coaxially aligned with the central vertical axis of the fastening member, and such chamber has an outer circumferential surface, a portion of which has a circumferential recess to receive and hold a circular locking ring. The roofing sheet is placed over top of the cup-like chamber and secured to the attachment plate by placing a flexible cap-like member over the roofing sheet and over the cup-like chamber with a circular locking ring inserted in the cap to lock the rubber roofing sheet in place. In an alternate embodiment of the subject invention, an additional cup member, of a soft and pliable material, is placed over the rubber roof sheet prior to the placement of the outer cap member. This additional, or inner, cap member helps prevent damage to the rubber roof sheet by the outer cap member and locking ring.
