About this detail

A one-and-a-half-inch metal deck supports six-inch rigid insulation providing R-thirty thermal performance, topped with a typical thermoplastic polyolefin membrane roofing system. A continuous sheet metal backing receives a thermoplastic polyolefin membrane roofing strip with heat-welded laps, maintaining a four-inch minimum overlap. Metal flashing with a hemmed drip edge, painted to match the roofing, laps down the exterior wall and engages a continuous cleat secured at sixteen inches on center. The exterior framing features typical exterior sheathing and continuous R-twenty-one batt insulation within the wall cavity.
