About this detail

This roof section details a PVC thermoplastic roof membrane installed over a cover board and substrate board, supported by R-30 rigid insulation and a vapor barrier. A protective Sarnatred walkpad is laid over treated smooth exterior-grade plywood sheathing at designated roof access locations, stairs, hatches, and ladders. The entire roofing buildup rests on a structural metal deck, specified to be painted black where exposed.
