Expert Verdict — Reviewed by the SuperArbor Pro Desk
Place breather vents where vapor drive accumulates in TPO assemblies, typically higher in the roof field or on retrofits over wet deck conditions, per the roof system manufacturer's layout. The pre-attached 60 mil flange speeds heat welding on white TPO. Verify flange thickness and placement against the membrane manufacturer's detail drawings before ordering.
Weld TPO flanges only with proper hot-air welding equipment and follow the membrane manufacturer's details and site safety requirements.
Order the FlashCo 4 in white TPO 1-way breather vent to protect your TPO roof assembly.
