Expert Verdict Reviewed by the SuperArbor Pro Desk

Vent fittings must be chemically matched to the membrane; a PVC body like this welds reliably to PVC sheets, while dissimilar materials need adapters or sealants. Detail the weld thoroughly around the base and check for fishmouths before final inspection. Keep spare vents on hand for maintenance calls on older PVC roofs.

Follow hot-air welding safety practices and ensure the roof surface is cool and dry before walking or working on it.
