About this detail

A pre-manufactured metal snap-on coping cap is installed over a nested stud for a continuous sloped parapet top. High-temperature self-adhered flashing and a termination bar are secured with stainless steel screws and washers, and two 1-1/2 inch stainless steel ring shank nails secure each face of the continuous cleat. A 2-inch aluminum tape separates the self-adhered flashing from the PVC roofing membrane, and an adhered PVC flashing membrane wraps the exterior wall. A pipe penetration passes through an 8-inch minimum concrete on metal deck assembly with polyiso rigid roof insulation, a 1/4-inch recovery board, and a 60-mil felt-backed fully adhered PVC roof membrane. A continuous self-adhered vapor retarder wraps tight to all penetrations, and a pre-manufactured curb flashing or PVC umbrella is welded at the top with a stainless steel hose clamp and hot-air welded flashing membrane.
