Tear Off, Recover, or Retrofit?
There are three ways to replace a commercial roof. Core cuts tell us which ones are open to you.
Tear-Off and Replace
Everything comes off down to the deck. Damaged deck gets replaced, new insulation goes down, then the new membrane and edge metal. The right call when the roof has two layers or wet insulation.
Recover
A new single-ply membrane over a cover board on top of the existing roof. It skips the tear-off cost, but only works over one layer that is dry. Core cuts and moisture readings decide it.
Retrofit Over Metal
On a metal building, foam flute fill and insulation board go over the existing panels, then PVC or TPO. No tear-off, new insulation, and a roof with no exposed screws. See metal roofing.
Signs It Is Time to Replace
Repairs stop making sense when you see these.
- Leaks in more than a few places, or the same leak coming back.
- Wet insulation across large areas of the roof.
- Membrane that is brittle, shrinking, or pulling away at the edges.
- Rusted metal panels or screws leaking across the whole roof.
- A roof past 20 years old with no warranty left.
What Comes With Every Replacement
This is the scope we price on every re-roof.
- Core cuts and moisture readings before we price.
- Deck and insulation replacement priced by the square foot.
- Insulation, cover board, and membrane sized to your building.
- New edge metal, flashings, and curbs.
- Manufacturer inspection and a No-Dollar-Limit warranty option.
What Commercial Roof Replacement Costs
The biggest price swing in a re-roof is whether the old roof has to come off. Here are the typical ranges for each path.
Typical Gulf Coast Cost Ranges
Typical Gulf Coast ranges for a 10,000 square foot low-slope roof replacement. Your inspection replaces these with one fixed price.
| System | Cost per Sq Ft | 10,000 Sq Ft Roof | On-Site Time |
|---|---|---|---|
| Single-ply recover over a dry existing roofTPO or PVC with cover board | $8.00 to $11.00 | $80,000 to $110,000 | 1 to 2 weeks |
| PVC or TPO retrofit over a metal roofflute fill, insulation board, new membrane, edge metal | $6.00 to $8.00 | $60,000 to $80,000 | 2 to 3 weeks |
| TPO tear-off and replace60 mil, code insulation, new edge metal | $13.00 to $16.00 | $130,000 to $160,000 | 2 to 3 weeks |
| PVC tear-off and replace50 to 60 mil, code insulation, new edge metal | $13.00 to $16.00 | $130,000 to $160,000 | 2 to 3 weeks |
| R-panel metal roof replacementpainted steel, with insulation | $11.00 to $13.00 | $110,000 to $130,000 | 2 to 3 weeks |
| Standing seam steel roofPVDF finish | $15.00 to $22.00 | $150,000 to $220,000 | 3 to 4 weeks |
Two existing layers or a gravel built-up roof push the price toward the top of the range. Wet insulation and rotten deck are priced by the square foot in your proposal, so you know the number before we open the roof.
Budget Lines Most Re-Roof Bids Leave Out
These are the items that turn a low bid into a high invoice. Ours are in the proposal.
Deck and Insulation Replacement
You cannot see wet insulation or rusted deck from the ground. We cut cores before we price and list a unit price for any replacement, so a surprise is a known number.
Edge Metal and Gutters
New edge metal, coping, gutters, and downspouts are part of a real replacement. Reusing tired edge metal is how roofs peel back in a storm.
Insulation Upgrades
A full tear-off usually means new insulation to today's standard. It adds cost up front and lowers your cooling bill every summer after.
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 Roof Replacement
Should we tear off or recover?
If the existing roof is one layer and the insulation is dry, a recover saves the tear-off cost. If there are two layers, or core cuts show wet insulation, it has to come off. We cut cores and show you the results before you choose.
How much does a commercial roof replacement cost per square foot?
On the Gulf Coast, commercial roof replacement typically runs $6 to $22 per square foot. A recover over a dry roof is $8.00 to $11.00, a PVC or TPO retrofit over metal $6.00 to $8.00, a full TPO or PVC tear-off $13.00 to $16.00, and standing seam steel $15 to $22. A 10,000 square foot tear-off and replace is roughly $130,000 to $160,000.
Do we have to add insulation?
On a full tear-off, yes. New insulation goes down to today's standard. It costs more up front and cuts your cooling bill for the life of the roof. On a recover or retrofit we add insulation board as part of the system.
How long will the work disrupt our building?
A 10,000 square foot replacement typically takes 2 to 3 weeks on site, weather permitting. We work in sections, dry in each one every day, and plan noisy work around your hours. Your business stays open.
What warranty comes with a new roof?
Every commercial roof we install carries our 5-year workmanship warranty. Most also carry a manufacturer No-Dollar-Limit warranty, up to 30 years depending on the system, issued after the manufacturer inspects the roof.
