Expert Verdict — Reviewed by the SuperArbor Pro Desk
Fastener length must be chosen so the screw penetrates the deck adequately after passing through insulation thickness; the 3 in. size suits thicker insulation builds or heavier attachment points. Follow the membrane manufacturer's fastening density and the FM 4470 assembly requirements to keep the warranty and approval valid. Order plates or washers separately to match the specified attachment pattern.
Roofing fasteners have sharp points and edges; wear gloves and eye protection when handling, installing or cutting.
