Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the cone size to the actual vent pipe diameter before ordering; an oversized cone can be field-tightened but an undersized one cannot. On re-roofs, replace old pipe flashings rather than reusing them, since the rubber or cone seal is a common leak point. Keep the uphill flange lapped under shingles to shed water over, not under, the base.
Metal flashing edges are sharp; wear cut-resistant gloves and follow ladder and roof fall-safety practices during installation.
