The Pearl District north of downtown is one of the densest concentrations of restaurants and food-service operations in San Antonio - the Pearl Brewery redevelopment, Hotel Emma, the weekend farmers market, and the surrounding bar and restaurant corridor along Broadway and the Museum Reach of the Riverwalk. The Southtown and King William neighborhoods carry a similar density of independent restaurants, food halls, and small commercial kitchens. Every one of those operations vents grease-laden exhaust through a rooftop exhaust stack, and grease is one of the most destructive materials a commercial roof membrane encounters.
TPO and EPDM are not grease-resistant. Grease penetrates the plasticizers in these membranes over time, causing accelerated oxidation and cracking around exhaust stack flashings. PVC - polyvinyl chloride - is the chemically resistant alternative. PVC membranes are inherently resistant to grease, fats, cooking oils, and many cleaning chemicals. Restaurant and food-service buildings across San Antonio's active dining districts have been running PVC under their exhaust stacks for decades, and the chemical resistance holds up. Commercial Roofers of San Antonio installs PVC systems on new restaurant construction, on recover-over-existing projects, and on partial-replacement zones around exhaust stacks on mixed-membrane roofs where TPO or EPDM covers the main field but PVC is needed at the chemical-exposure zones.
