About this detail

The structural deck is covered with an optional air and vapor barrier and securely fastened insulation. Treated wood nailers match the height of the insulation and support the roof edge, anchored to resist a minimum force of 300 pounds per linear foot. The Sarnafil membrane extends over the roof edge and is secured with Sarnaclad metal fastened at 4 inches on center staggered using 1-inch galvanized annular ring nails, with a Sarnafil flashing strip hot-air welded in place. A metal gutter is attached with metal gutter supports at the edge. A cut-in reglet metal counterflashing is sealed with a backing rod, lead wedges force-fit, and Sikaflex-1A sealant.
