Duro-Last PVC, Built for Gulf Coast Roofs
PVC is a white, heat-welded single-ply membrane that resists grease, chemicals, and fire better than any other single-ply. Duro-Last makes its PVC flashings in the factory to fit your roof.
Factory-Made Flashings
Duro-Last prefabricates curb flashings, pipe boots, and corners to your roof's measurements. Fewer field seams means fewer places to leak.
Grease and Chemical Resistance
Restaurant exhaust, oils, and chemicals break down other membranes. PVC holds up. It is the right roof for restaurants and food service buildings.
No-Dollar-Limit Warranties
As a Duro-Last approved contractor, we offer No-Dollar-Limit warranties up to 30 years, depending on the system. Duro-Last inspects the roof before it issues the warranty.
Where PVC Wins
PVC is our first pick on these buildings.
- Metal buildings, as a retrofit over the existing panels.
- Restaurants and roofs with grease exhaust.
- Roofs with many curbs, skylights, and penetrations.
- Buildings where the owner wants the longest warranty.
- Flat roofs that pond and need a membrane that tolerates water.
What Goes Into Our PVC Roofs
This is the system we installed on our most recent commercial roofs.
- Duro-Last Duro-Tuff 50 mil white PVC, or thicker where the warranty calls for it.
- EPS flute fill and polyiso insulation board over metal roofs.
- Induction-welded or mechanically attached, sized to your wind design.
- New wood nailers, edge metal, gutters, and downspouts.
- Manufacturer inspection and a No-Dollar-Limit warranty.
What a PVC Roof Costs
PVC costs a little more than TPO. Here is what it typically runs and what drives the price.
Typical Gulf Coast Cost Ranges
Typical Gulf Coast ranges for a 10,000 square foot PVC roof. Your inspection replaces these with one fixed price.
| System | Cost per Sq Ft | 10,000 Sq Ft Roof | On-Site Time |
|---|---|---|---|
| PVC recover over a dry existing roof50 mil, cover board | $8.00 to $11.00 | $80,000 to $110,000 | 1 to 2 weeks |
| PVC retrofit over a metal roofflute fill, insulation board, 50 mil | $6.00 to $8.00 | $60,000 to $80,000 | 2 to 3 weeks |
| PVC tear-off and replace, mechanically attached50 to 60 mil, code insulation | $13.00 to $16.00 | $130,000 to $160,000 | 2 to 3 weeks |
| PVC tear-off and replace, fully adhered60 mil, code insulation | $13.00 to $16.00 | $130,000 to $160,000 | 2 to 3 weeks |
PVC usually runs $0.25 to $0.50 per square foot more than TPO. You pay that for grease and chemical resistance and for factory-made flashings that fit your curbs and corners.
What Changes a PVC Price
Three things decide most PVC budgets.
What Is Underneath
Over metal, the price includes flute fill and insulation board. Over an old flat roof, it depends on whether core cuts show dry insulation you can keep.
Curbs, Skylights and Pipes
Each penetration gets a prefabricated or field-welded PVC flashing. A roof with 14 skylights costs more than a clean roof, and the price shows each one.
Gutters and Edge Metal
New gutters, edge metal, and wood nailers are where metal-building retrofits spend real money. We list them by the linear foot.
Ranges are installed costs for a simple 10,000 square foot low-slope roof. Deck, purlin, and wet-insulation replacement, HVAC curb work, and permits are priced after we inspect the roof.
"Jim Brock is the best project manager ever! He constantly communicated with me about the materials, build and timeline. No stones were unturned! Exceptional work by his team."
From Inspection to Warranty
Every commercial roof runs through one contract and one project manager. You make the decisions. We carry the crew, the permit, the inspections, and the warranty paperwork.
Step 1. Roof Inspection and Core Cuts
We walk the roof and check the membrane or panels, seams, flashings, curbs, drains, gutters, and edge metal. We cut cores to see the layers and test the insulation for moisture, and we look at the deck or purlins from inside when we can.
Step 2. Options and a Fixed Price
You get a written proposal with every layer, thickness, fastening pattern, and warranty term listed, plus a fixed price. When repair, coating, recover, and replacement are all real options, we price them side by side.
Step 3. Wind Design and Permit
We size the fastening, perimeter and corner enhancement, and edge metal to the design wind speed for your address, then pull the permit with the city or county that has your building.
Step 4. Schedule Around Your Business
We plan the work around your hours. On occupied buildings we work in sections, protect HVAC intakes, and dry in every section before the crew leaves. Your doors stay open.
Step 5. Install With Daily Updates
Your project manager is on the roof with the crew and sends progress photos. Hidden damage, like rusted purlins or wet insulation, is priced at the unit price in your proposal and approved by you before we fix it.
Step 6. Inspection, Warranty and Closeout
The manufacturer inspects the finished roof before it issues the warranty. You get the warranty, the final inspection, lien waivers, and a photo record of the roof, start to finish.

Why Building Owners and Property Managers Hire Us
One Contractor, Roof and Building
We are a licensed general contractor, not only a roofer. When a leak has ruined ceilings, drywall, or insulation, the same crew and the same project manager fix the inside too.
One Fixed Price, in Writing
The proposal lists the system, every layer, the warranty term, and unit prices for hidden damage. The price changes only through a written change order you sign first.
Built for Small and Mid-Size Buildings
Offices, retail centers, churches, metal shops, and apartments are our focus. Your roof gets a dedicated project manager, not the crew left over from a warehouse job.
The Credentials Behind Every Commercial Roof
Wise Builders holds Alabama General Contractor License #60291 and is a Duro-Last approved contractor, which lets us offer manufacturer No-Dollar-Limit warranties up to 30 years, depending on the system. Every commercial roof also carries our 5-year workmanship warranty. We carry general liability and workers' compensation and are BBB accredited.
Before you sign with anyone, ask for the license number, a certificate of insurance, and a sample of the warranty you will actually receive. A No-Dollar-Limit warranty covers labor and materials for leaks. A materials-only warranty does not. We send ours with the proposal.
"The contract was clear and all work was performed on schedule. A certificate of compliance was issued by a third party after inspection. It is refreshing to find a company like this."
Frequently Asked Questions About PVC Roofing
PVC vs TPO: which is better?
Both are white, heat-welded single-ply roofs. PVC costs $0.25 to $0.50 per square foot more and resists grease, chemicals, and fire better, with factory-made flashings and longer warranty terms. TPO is the better value on a simple roof with no grease exposure.
Why PVC for restaurants?
Grease from kitchen exhaust breaks down TPO, EPDM, and asphalt roofs. PVC resists it. Any roof with a grease hood should be PVC around the exhaust, and usually across the whole roof.
Can PVC go over a metal roof?
Yes. Foam flute fill goes in the panel ribs, insulation board goes over the top, and the PVC goes over the board. It is the system we used at The Homestead Mobile and the Mobile SPCA.
What is prefabricated PVC?
Duro-Last measures your roof and builds the membrane sections, curb flashings, pipe boots, and corners in its factory. The crew installs and welds them on site. Fewer field seams means fewer leaks.
How much does a PVC roof cost?
On the Gulf Coast, a PVC roof typically runs $6 to $16 per square foot: $8.00 to $11.00 as a recover over a dry roof, $6.00 to $8.00 as a retrofit over metal, and $13.00 to $16.00 as a full tear-off with code insulation. Plan on $0.25 to $0.50 per square foot more than TPO.
What warranty comes with a Duro-Last roof?
Duro-Last No-Dollar-Limit warranties cover labor and materials for leaks, up to 30 years depending on the membrane and system. Every roof also carries our 5-year workmanship warranty.
