Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the vent's TPO skirt to the same brand/compatibility class of TPO membrane on the roof to ensure a sound weld. Passive gravity vents work best when intake ventilation is balanced; calculate required NFVA and divide by 264 sq in. per vent to determine quantity. Confirm curb height and curb framing before ordering, as the curb is not included.
Heat-welding TPO requires trained installers; follow the membrane manufacturer's welding parameters and roof safety practices when working at height.
