The roof construction integrates a standard roof drain and an overflow roof drain set flush with the roof assembly. The roof membrane extends directly into the roof drain and is sealed securely with plastic roofing cement. A gravel stop surrounds the perimeter of the drain assembly to retain the roof aggregate. Coordination with the roofing contractor is required during installation to ensure proper flashing and watertight integration.
