Commercial Roof Cost
What Commercial Roof Work Costs in Baton Rouge
Commercial roofs are priced by square footage, system type, and how much wet insulation has to come out, which is why a real number requires walking the roof and probing it. The bands below are typical starting points for the Baton Rouge market, not a quote.
Leak repair
$600 - $2,500
Seam or lap repair, penetration and curb reflashing, pitch pocket rebuild, drain or scupper detailing, isolated membrane patching.
Usually one day, often outside business hours.
Section restoration
$3,000 - $15,000
Saturated insulation cut out and replaced, membrane sections replaced, coating or recover applied over a sound substrate.
Typically 2 to 5 days, phased by area.
Full system replacement
Quoted after inspection
Tear-off and new low-slope system with insulation, cover board, membrane, and all edge, curb, and drain detailing.
Typically 1 to 3 weeks depending on square footage.
What changes the price
- Total square footage and the number of roof levels
- Existing system type and how many layers are already up there
- How much insulation is saturated and has to be removed
- Number of HVAC curbs, penetrations, drains, and scuppers
- Roof access: interior hatch, crane, or lift staging
- Whether work has to happen after hours to keep the business open
Timeline
How a Commercial Roof Project Runs
The goal is a roof that stops leaking without shutting your doors. Here is how we sequence the work around an operating building.
- 01
Day 1
Roof evaluation
We walk the roof, map leak locations against interior reports, check drains and low spots, and probe suspect areas to see how far moisture has traveled.
- 02
Day 1 to 3
Written scope and options
You get repair, restoration, and replacement priced as separate paths, with the photo evidence and expected service life for each so you can budget it.
- 03
Before work
Access and schedule plan
We agree on staging, dumpster placement, work hours, and which areas get done first so entrances, parking, and tenant operations stay usable.
- 04
Phase 1
Dry-in and critical repairs
Active leaks and open details get handled first so interior damage stops while the larger scope is under way.
- 05
Phase 2
System work, area by area
Wet insulation is removed, new insulation and membrane are installed, and every curb, drain, and edge detail is flashed to spec before we move to the next section.
- 06
Closeout
Inspection, photos, and warranty
We walk the finished roof with you or your property manager, provide photo documentation for your records, and hand off the warranty paperwork.

Frequently Asked Questions
Commercial Roofing, Common Questions
Do you work on flat and low-slope commercial roofs?
Yes. Flat and low-slope systems are their own trade: leaks usually start at seams, penetrations, curbs, and drains rather than in the open field of the roof. We inspect those details specifically.
Can you repair the roof without shutting down my business?
In most cases yes. We schedule around your hours where we can, stage materials to keep entrances clear, and phase larger replacements section by section so the building stays usable.
Why does water pond on my commercial roof?
Ponding usually means clogged or undersized drains, a low spot from deck deflection, or insulation that has taken on water. Standing water accelerates membrane failure, so we identify the cause instead of just patching the wet area.
How do you document commercial storm damage?
We photograph the damage in detail, measure the roof, and provide an itemized written scope and estimate. It is a dated record you can keep for your files or submit yourself.
Repair or replace: how do I decide?
It comes down to how much of the membrane and insulation is still sound. If the failures are isolated at penetrations and seams, repair is the right call. If the insulation is saturated across large areas, repairs stop holding and replacement is cheaper over time. We show you the photos behind the recommendation.
What kind of properties do you service?
We serve commercial and multi-unit properties across Greater Baton Rouge, including offices, retail, and small industrial buildings. Call with your building type and roof size and we will tell you honestly whether it is a fit.
