The roof assembly integrates a drain bowl set into the roof framing and supported by a deck clamp underneath. A round cut in the thermoset membrane extends approximately one inch past the clamping ring, with sealant placed between the drain bowl flange and the roof membrane. The roofing system incorporates tapered rigid insulation over roof framing, finished with closed-cell spray foam insulation below. A standard clamping ring secures the membrane, while an elevated overflow clamping ring and drain strainer maintain proper drainage levels and prevent blockage.
