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 reroofing 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.
