Expert Verdict — Reviewed by the SuperArbor Pro Desk
Retrofit drains like the Hercules are the go-to fix when an existing cast iron or PVC drain body is sound but the drain itself has failed, since the work stays on the roof and avoids interior disruption. Verify pipe material and inside diameter before ordering, and confirm the U-Flow Seal size matches the pipe for a watertight fit.
Follow roofing jobsite fall-protection requirements and confirm the roof deck can support work around the drain opening before starting a retrofit.
Order the OMG U-Flow Hercules Aluminum RetroDrain in your pipe size for a fast, watertight rooftop drain retrofit.
