Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the collar size closely to the pipe diameter so the base seats flat and the collar can be sealed to the pipe. The 26 ga galvanized stock holds its shape well during installation. Install so water sheds over, not under, the downslope flange, and use the 1/2 in. size only for small diameter vent lines.

Use proper roof access and fall protection equipment when working at pipe penetrations on any roof slope.


Choose TopShield 26 ga galvanized all pitch pipe flashing with FHA base in the size your vent stack needs.
