When securing a metal drip edge to a roof deck, you should use corrosion-resistant roofing nails, such as hot-dipped galvanized steel or ring-shank stainless steel nails with wide flat heads. Avoid using standard drywall screws or common nails, as they can rust quickly, weaken over time, or allow moisture leaks around the fastener penetration. Nails should be driven through the pre-punched holes in the nailing flange every ten to twelve inches to ensure the metal flashing remains completely rigid and secure.
