Designed for existing through-wall/side-wall or scupper drainage pipes, the aluminum and stainless steel drain components provide durability and compatibility with single ply, BUR and modified bitumen roofing systems. A metal clamping assembly creates a compression type termination in both vertical and horizontal wall flashings. The Scupper RetroDrain features the patented RAC Backflow Compression Seal for attachment to PVC or cast iron leader pipes, and a removable drain strainer. Available in 3-in., 4-in., 5-in., and 6-in. sizes. Custom configurations are also available.

OlyFlow® RetroDrains are designed to replace existing drains in re-roofing applications. Installed from the roof surface, OlyFlow RetroDrains are engineered to be installed without removing the existing plumbing or fixture while providing a watertight connection to the roof system and the existing plumbing.
As with all building materials it is the responsibility of the installer to review its usage with a design professional to confirm safety, compatibility and acceptance with the roof cover manufacturer as well as local building codes.
Superior productivity. Superior performance.
