PVC is a thermoplastic single-ply roofing membrane used on low-slope buildings. Like TPO, it relies on heat-welded seams but has its own material chemistry, accessories and compatibility requirements.
Where This System Fits
PVC may be considered for commercial, multifamily and selected residential low-slope applications based on project requirements.
What We Evaluate Before Installation
We inspect existing membrane identification, substrate, insulation, drainage, penetrations, curbs, perimeter conditions and repair history.
Installation Details Matter
The material name alone does not determine performance. Edges, transitions, penetrations, flashings, drainage and substrate conditions must be compatible with the selected system and installed as a complete assembly.
Repair or Replacement
A localized defect may be repairable when the surrounding system is in serviceable condition and compatible repair materials are available. Widespread deterioration, repeated leaks or substrate problems may justify replacement.
Important Considerations
Repairs should use compatible materials. A surface that looks similar to PVC is not enough to assume compatibility, so existing membrane identification can be important before repair.
