A louver roof screen assembly is supported by galvanized hollow structural section framing per structural drawings. The assembly incorporates formed aluminum flat metal panels and metal louvers sealed with backer rod and continuous sealant. At the roof level, the galvanized metal hood flashing is secured over the painted roof cover board and rigid insulation with stainless steel draw bands and fasteners with washers. A fleece-backed fully adhered PVC roofing membrane with PVC flashing ties into the system over fire-treated wood blocking, a vapor retarder, and a metal deck roof.
