Roofs Waterproofing / Flashing Insulation Drainage

About this detail

Roof drainage and overflow drainage are integrated into a wood deck assembly featuring five-eighths inch tongue-and-groove plywood, three-quarter-inch plywood sheathing, three inches of rigid insulation, and an EPDM membrane secured with bonding adhesive. The primary and overflow drains feature strainer baskets and compression rings, with a one-half-inch minimum compression ring layer and EPDM membrane aligned to the drain compression clamp height. Wood blocking is provided at typical locations around the drain sumps, and outlets connect to the sewer per mechanical, electrical, and plumbing engineering plans.
