Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the FlashVent size to the pipe diameter with a slight allowance for the cone, and select the color closest to your TPO membrane for a uniform appearance. Heat-weld or flash the base into the field sheet per the membrane manufacturer's detail requirements, and confirm pipe penetrations are plumb before installation.

Hot-air welding of TPO details requires trained installers and fire-watch precautions; follow the membrane manufacturer's installation instructions and local codes.
