ABSTRACT:
A rotatably drivable roofing fastener of the invention of a synthetic-resinous-polymeric material, such as of an injection molded cut-glass-fiber filled nylon composition, includes means adapted for drillably cutting into insulation material during fastener installation and also means adapted to matingly engae a special tool providing rotatable driving while the tool also concurrently rotatably drives and matingly engages the head of a metal screw, which is located within an upper region of an aperture running lengthwise through the fastener's head and downwardly extending shank, so that the metal screw's threaded shank and tip extending from the aperature at the bottom of the fastener penetrates roof deck or existing roof structure upon rotatable driving so as to secure insulation material to roof deck or existing roof surface. Upon seating of the roofing fastener/metal screw and disengagement of the tool, a plug of insulating material is inserted into the aperture's upper region to provide fastener assemblies consisting essentially of the plug, the roofing fastener and the metal screw in the just-described relationship. A plurality of the fastener assemblies enable construction of roof assemblies, which in addition to roof deck, insulation material and fastener assemblies include an overlying exteriorly exposed waterproofing covering or membrane.
