Expert Verdict — Reviewed by the SuperArbor Pro Desk
Hercules RetroDrains are a strong choice for reroofs over occupied buildings because the retrofit installs entirely from above. Match the drain size to the existing pipe and the dome color to the membrane aesthetic. Choose the flip-top SuperDome on roofs with heavy debris loads to simplify maintenance.
Use proper fall protection during rooftop work and verify the existing pipe condition and local plumbing code requirements before retrofitting a drain.
