Commercial PVC Roofing in West Texas
PVC is a heat-welded thermoplastic vinyl single-ply membrane, specified where grease, chemical exhaust, or animal fats would attack TPO. We install 60 mil and 80 mil reinforced PVC for West Texas restaurants, food manufacturing, and chemical-exposed buildings, probe-test every seam, and offer material, system, and NDL warranties. PVC is the right call when chemical resistance and a Class A fire rating matter more than lowest cost.
- 60 and 80 mil
- High, grease and fat
- Class A, UL 790
- 20 to 25 years
- Restaurants, food, chemical
- Material to NDL
What PVC is, in plain terms
PVC is a single sheet of reinforced vinyl membrane rolled across the roof and fused at the seams with a hot-air welder, the same way TPO is installed. The difference is chemistry. PVC resists the grease, oils, and animal fats that attack a TPO membrane, which is why it is the default for kitchens and food manufacturing.
PVC is also naturally fire resistant and self-extinguishing, earning a Class A fire rating under ASTM E108 and UL 790. That matters for buildings with cooking operations, where a fire-rated roof assembly may be required by code or by the building insurer.
When PVC is and is not the right call
- +Restaurant with grease-laden kitchen exhaust
- +Food manufacturing or processing plant
- +Chemical exposure from process stacks
- +Class A fire rating required by code or insurer
- +Roof where TPO would plasticizer-leach from contact
- -Standard warehouse with no chemical exposure, use TPO
- -Budget sensitive where reflectivity alone matters
- -Severe hail exposure where single-ply will fracture
- -Saturated deck needing tear-off regardless of membrane
How we install PVC
Substrate and insulation
Deck inspected, tapered insulation and cover board fitted to manage ponding and thermal loss, routed to withstand chemical exposure.
Membrane layout
Reinforced PVC rolls positioned with overlaps per ANSI/SPRI, perimeters and corners treated as higher-stress zones.
Heat-welded seams
Hot-air welder fuses the seam, every seam probe-tested, sampled with a destructive peel test per ASTM.
Grease and penetration flashing
Pipe boots, grease wraps, and curb flashing welded to manufacturer detail for chemical-exposed penetrations.
Attachment verified
Mechanical fasteners or adhesive checked for wind uplift per ASCE 7, edge metal per ANSI/SPRI ES-1.
Final walk and warranty
Punch list closed with the owner, photographs filed, manufacturer warranty registered with exclusions listed up front.

PVC roofing questions
What is PVC roofing and where is it used?
PVC is a thermoplastic vinyl single-ply membrane, heat-welded at the seams like TPO, but chemically resistant to grease, oils, and animal fats. It is specified for restaurants, food manufacturing, and buildings with exhaust stacks where TPO would degrade. PVC costs more than TPO and is the right call when chemical exposure is the deciding factor.
PVC vs TPO, which is better for Lubbock?
TPO is the cost default. PVC is specified where grease from kitchen exhaust, chemical processing, or animal fats will attack a TPO membrane. PVC holds reflectivity and weldability similar to TPO at a higher cost. For a standard warehouse or retail roof with no chemical exposure, TPO is the right call and PVC is over-specification.
How long does a PVC roof last?
A 60 mil or 80 mil reinforced PVC roof installed to manufacturer specifications typically lasts 20 to 25 years in the West Texas climate. Plasticizer stability and seam weld integrity are the life drivers, which is why PVC thickens and welds more consistently than early-generation products.
Is PVC roofing fire resistant?
PVC is naturally fire resistant and self-extinguishing, which earns Class A fire ratings under ASTM E108 and UL 790 testing. That matters for buildings with cooking operations or where a fire-rated roof assembly is required by code or insurance.
Can a PVC roof be coated?
Yes, when core cuts show dry insulation and the membrane is aging but not fractured, a compatible coating extends a PVC roof. The surface must be cleaned and primed per the coating manufacturer, because PVC is slick and not every coating bonds without primer.
What does PVC roofing cost per square foot in Lubbock?
As of August 2026, typical installed PVC ranges for sound South Plains commercial roofs are about $14 to $24 per square foot. Thickness, attachment, insulation, access, and tear-off move the number. Chemical exposure or fire rating requirements usually justify the premium over TPO.
What warranty comes with PVC?
Manufacturer material warranties cover the membrane, and manufacturer system and NDL warranties cover the full assembly installed by a certified contractor. PVC warranties for grease-exposed roofs often carry exclusions for chemical contact outside the tested range, which we list before you sign.
How do you test PVC seams?
Every heat-welded seam is probe-tested and sampled with a destructive peel test per ASTM standards, the same quality control used on TPO. Seam failure is the most common single-ply leak source, so weld integrity is the gate, not an option.
