PVC Roofing in Pittsburgh, PA
PVC is a single-ply membrane with heat-welded seams, much like TPO, but with one big difference: it holds up to grease, oils and many chemicals that soften and destroy rubber and asphalt roofs. That makes it the usual choice for restaurants, bars and commercial kitchens, where exhaust fans blow cooking grease onto the roof every day, and for some light-industrial buildings. Pittsburgh's neighborhood business streets are full of restaurants in older brick buildings, often with a rubber or tar roof that is breaking down around the exhaust fan. We check what is on the roof and what is under it, then price PVC alongside any cheaper option that would actually work.

PVC Roofing — FAQs
Kitchen exhaust puts grease on the roof, and grease attacks EPDM and asphalt. PVC resists it, so the roof around the fans doesn't break down early.
Both are white, heat-welded single-ply membranes. PVC costs more and resists grease and chemicals better; TPO is the usual pick where that exposure isn't an issue.
Sometimes. If the rest of the roof is sound, a section can be replaced with grease containment added at the fans. We'll tell you which makes sense.
It is priced after a roof check, because the exposure, size and number of fans and curbs vary so much. It usually costs more than TPO or EPDM.
