Expert Verdict — Reviewed by the SuperArbor Pro Desk

A galvanized base with an elastomer collar is the standard choice for asphalt shingle roofs where a mill-finish metal base is preferred over plastic. Match the collar to the vent pipe diameter with a snug fit, and lap the base shingle-style above the pipe per flashing best practice. For steeper pitches above 45° or hot type B vents, verify the application is approved before install.

Work on roofs only with proper fall protection, and keep the elastomer collar away from vent surfaces hotter than its 180°F rating.
