Abstract
The present disclosure relates to a penetrating fastener for a roofing system having a flexible waterproof membrane adhesively attached to an upper layer which is fastened to a roof deck. The fastener is dimensioned to extend through the upper layer and threadingly engage the lower roof deck. The fastener includes a self-drilling tip for piercing the upper layer and the roof deck and a self-tapping threaded shank portion located above the tip. An unthreaded shank portion is located adjacent the threaded shank portion. A tapered collar is located above the unthreaded shank portion. The fastener further includes a driving head which has a flange extending at an angle from a first side of the head to the tapered collar for reducing the tensile forces associated with the head being installed flush with or slightly below the upper layer. The unthreaded shank portion, tapered collar and driving head together form an unthreaded length of the penetrating fastener that is at least as great as a thickness of a portion of the upper layer. A method includes attaching a roofing system using the penetrating fasteners.
