Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match fastener length to insulation thickness plus required deck embedment; 4 in. suits thicker polyiso assemblies over common decks, but always verify embedment per the JM data sheet. Use a clutch-adjusted screw gun to avoid stripping the plate or overdriving, and pair with the correct JM plate size for the membrane and wind uplift zone specified.
Wear eye protection when driving fasteners and follow the manufacturer's data sheet, uplift requirements and local code for your roof assembly.
