Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match screw length to your total assembly thickness: membrane plus insulation plus deck penetration. Use the spade point for fastening where a punching point suits the deck, and keep the same fastener family the membrane manufacturer requires so the roofing warranty stays intact. Buckets of 1,000 cover typical fastener layouts efficiently on large commercial jobs.
Install screws with the correct #3 Phillips driver and appropriate fall protection when working on roof surfaces.
