Expert Verdict — Reviewed by the SuperArbor Pro Desk
Size the retrodrain to the existing scupper and verify head-height and overflow requirements against local drainage codes before ordering. Aluminum construction suits most commercial environments but should be isolated from dissimilar metals per the roof system details. Coordinate the retrofit with the membrane flashing detail so the new outlet integrates cleanly with the existing system.
Scupper retrofits are performed at the roof edge; use appropriate fall protection and verify structural condition of the wall opening before working.
Order the OMG Aluminum Scupper Thru-Wall Retrodrain in the size your scupper needs.
