Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cap nails are the standard choice for holding underlayment and synthetic membranes in wind events, since the wide cap prevents tearing through the sheet. Space them per the underlayment manufacturer's instructions, typically along laps and field rows, and keep a bulk 50 lb. carton on hand for large roofs to avoid mid-job fastener runs.
Wear gloves when handling bulk nails and keep the carton secured to prevent spills on walkways and ladders.
