The single-ply that holds up where hydrocarbons live on the roof.
PVC (polyvinyl chloride) roofing membrane predates TPO by two decades and remains the correct spec for a specific set of commercial buildings: anywhere the roof sees sustained exposure to chemicals, grease, fats, oils, or hydrocarbon fumes. The formulation resists plasticizer migration, holds up against animal fats from restaurant exhaust, and does not go brittle in the presence of solvents or drilling-fluid overspray the way a standard TPO membrane will.
In West Texas and New Mexico, that means PVC is the default membrane for restaurants with high-BTU exhaust, oilfield service company buildings in Midland, Odessa, Hobbs, and Carlsbad, chemical distribution warehouses, food processing plants, and industrial facilities downstream of scrubbers. It is also the right call on buildings that will see rooftop grease or fuel handling of any kind.
PVC costs a modest premium over TPO — usually 10–20% at the material level. On the wrong building, that premium is wasted. On the right building, it’s the difference between a 25-year roof and a 10-year roof.

When PVC is the correct call
The building types where PVC pays for itself.
01. Restaurants & food service
Animal fats, grease, and cooking oils in exhaust plumes attack standard TPO. PVC is the industry-standard membrane for anywhere near a high-BTU commercial hood.
02. Oilfield service facilities
Yards handling drilling fluids, completions chemicals, or refined-product blending expose roofs to plasticizer-eating solvents. PVC holds up where TPO won't.
03. Chemical distribution
Warehouses and blending facilities with fugitive chemical vapors need chemical-rated membranes. PVC is the default; specialty formulations for the harshest exposures.
04. Food processing
Rooftop condensers, wash-down runoff, and process exhaust all favor PVC's chemical resistance and heat-welded seam integrity.
05. Industrial & manufacturing
Where the process produces rooftop chemical exposure — plating shops, print shops, pharmaceutical, electronics — PVC is the safer specification.
06. Retrofits over asphalt
PVC is one of the few single-plies rated for direct install over an existing asphalt or coal-tar roof with a proper separator sheet. Useful on older buildings where full tear-off would be prohibitive.
From exposure survey to warranty in four steps.
Exposure survey
On-site assessment focused on identifying what actually ends up on the roof — exhaust plume, chemical handling, rooftop equipment. Determines whether PVC is required.
Spec & estimate
Membrane thickness, fastening system, manufacturer, and warranty term matched to the building. Fixed-price estimate valid 60 days.
Installation
Tear-off or approved recover, insulation to spec, cover board where required, PVC installed with hot-air-welded seams tested with a probe.
Maintenance program
Post-install inspection at 6 and 12 months, annual maintenance visits, and warranty administration. See roof maintenance.
What actually decides the specification.
Exposure
The deciding variable, every time.

The head-to-head comes down to exposure. Where the roof will see chemical, grease, or hydrocarbon exposure over its service life, TPO loses. The plasticizers migrate out of the membrane, it goes brittle, seams fail, and the warranty is void because the manufacturer will (correctly) point to the exposure as an out-of-scope condition. Where the roof won’t see that exposure, TPO is the more cost-effective single-ply and reflects more solar energy.
Two situations where PVC also wins even without chemical exposure: retrofits over an existing asphalt or coal-tar roof, where PVC’s material chemistry allows direct install (with a separator sheet) that TPO can’t do; and buildings with very high uplift requirements where PVC’s tensile strength provides more headroom in the fastening pattern.
Everywhere else, TPO is the right economic call. See modified bitumen for high-traffic redundant systems and roof coatings for extending an existing membrane.
Commercial PVC roofing, answered.
In chemical exposure, yes. On a restaurant with a hooded exhaust, a standard TPO membrane will show plasticizer migration within a few years and be structurally compromised well before its warranty date. A PVC membrane will still be pliable and heat-weldable at year 20+. On a building without that exposure, the practical difference is smaller and TPO's higher solar reflectance often wins.
A 60 or 80 mil PVC over a cover board carries hail ratings comparable to equivalent TPO. Where hail resilience is the primary concern and chemical exposure is not, we generally still spec 80 mil TPO. Where both matter, PVC at 60 or 80 mil is the right answer.
Sometimes — that's actually one of PVC's edges. With the right separator sheet and manufacturer approval, PVC can be installed directly over an existing asphalt built-up or modified-bitumen roof, avoiding tear-off cost. We use a moisture scan to confirm the existing roof qualifies. Where a recover isn't viable, we go to full replacement.
Sika Sarnafil, Carlisle SynTec, IB Roof Systems, Duro-Last, and others depending on the project's warranty and spec requirements. We hold manufacturer certifications on the systems we install and do not sub out installation to non-certified crews.
PVC has an active recycling stream — post-consumer PVC roofing can be reprocessed into new membrane at end of service life. The membrane itself is highly reflective in its white formulation and reduces cooling load through the life of the roof.
