PVC and TPO roofing is recommended for restaurants and facilities with rooftop grease or chemicals because they resists animal fats, oils, and many chemicals, and its heat-welded seams create durable, watertight joints. Most failures on food-service roofs start when grease softens or embrittles other membranes, leading to seam splits and ponding leaks. PVC and TPO stay stable around exhaust fans, tolerates frequent wash-downs, and cleans without absorbing residue. In our experience serving the Rochester area, roofs that see constant fryer exhaust typically last longer with PVC and TPO than with non–grease-resistant systems. A veteran tech knows that if you can smell the kitchen on the roof, the membrane is being exposed every day. If you have TPO or modified bitumen, use proper grease containment; if exposure is heavy, consider a PVC or TPO overlay or full replacement. Have a qualified roofer inspect the membrane and the grease path from the fan before the next cleaning cycle.
