PVC: the specialist for demanding roofs

Heat-welded like TPO, but with a chemistry that shrugs off grease, oils, and chemical exposure. If your roof lives above a kitchen or a process floor, PVC is usually the answer.

Where PVC earns its premium

Every restaurant exhaust fan rains a fine mist of grease onto the roof around it — and grease degrades most membranes years ahead of schedule. PVC's chemistry resists it, which is why food service, kitchens, and processing facilities spec PVC almost by default. Add hot-welded seams and strong reflectivity, and it's a premium membrane that earns its price on the right building.

PVC also carries one of the longest performance histories among weldable membranes. For buildings without chemical exposure, TPO usually pencils out better — and we'll tell you so. This is about matching chemistry to what your roof actually endures.

When PVC is the right spec

  • Restaurants & kitchens

    Grease exhaust destroys ordinary membranes — PVC is built for it.

  • Chemical or oil exposure

    Process facilities and maintenance areas with rooftop discharge need resistant chemistry.

  • Ponding concerns

    Welded seams and PVC's plasticized flexibility handle slow-draining roofs well.

  • Reflectivity wanted

    White PVC performs like TPO against Gulf-region cooling loads.

Our approach

How we install PVC

  • Exposure assessment

    We map what the roof actually endures — exhaust, discharge, traffic — and spec accordingly.

  • Itemized proposal

    Membrane, insulation, and detail package priced line by line against the alternatives.

  • Welded installation

    Hot-air welded seams, reinforced details at curbs and penetrations — checked as we go.

  • Service planning

    High-exposure roofs deserve scheduled checkups; we set the cadence with you.

FAQ

PVC Roofing questions, answered

Why is PVC more expensive than TPO?
The resin and plasticizers cost more to produce, and the membrane carries specialist capabilities — chemical resistance chief among them. On a roof that needs those capabilities it's the economical choice; on one that doesn't, we'll usually point you to TPO.
Our restaurant roof keeps failing around the exhaust fans. Is that fixable?
That's the classic grease-degradation pattern, and yes — PVC in the exposure zones (or across the roof) is the standard fix. We also detail grease containment at the fans themselves, which extends any membrane's life.
How long does PVC last?
Comparable to other premium single-plies — commonly 20–30 years with sound installation and maintenance, even under exposures that would halve the life of other membranes.
Can PVC be welded to TPO?
No — the chemistries are incompatible for welding, which matters when patching or tying into existing roofs. It's one of the details we verify before any repair or partial replacement on an existing single-ply roof.
