Roof Drains


USA: Roof Drains: Roof Drain Manufacturers





Roof drains are drainage fittings which allow water to be carried off flat roofs. They consist of a base, which may be made of copper or cast iron, and a dome strainer, usually made of PVC, which is designed to prevent leaves or debris from entering the drain. Roof drains are normally fitted to the horizontal surface of a flat roof, which may be sealed with liquid applied asphalt or with synthetic rubber roofing material. Special roof drains are also available for fitting through a vertical parapet wall. Sump receivers and deck clamps are also available, for fitting below roof drains.
