Expert Verdict — Reviewed by the SuperArbor Pro Desk

On shake and wood-look roofs, a flashing formed for that coursing seats better than a flat flange. Confirm the vent pipe diameter before ordering, and replace flashings during re-roofing rather than reusing old ones. Paint mill galvanized to match the finished roof if desired.

Metal flashing edges are sharp; wear cut-resistant gloves and follow safe roof access practices.
