Commercial roof repair and replacement in Jacksonville
Updated September 2026
A leaking commercial roof costs more than the repair: stock, equipment and tenants sit under it. We respond to leaks any hour, keep a written record of every visit, and plan replacements around the business operating below.

- Work planned around business hours
Commercial roofing in Jacksonville, FL covers leak response, repairs and full replacement on low-slope and metal roofs over retail, office and warehouse buildings, most often TPO, modified bitumen, built-up, standing seam or exposed-fastener metal. Replacements are permitted through JaxEPICS and phased so the building can stay open while the roof is done.
Roofs over a business
What building owners and managers need from a roofer
Commercial roofs are mostly low-slope membranes and metal, and they fail in the same places: seams, drains, rooftop equipment curbs, parapet walls and penetrations for pipes and conduit. What changes is the stakes. A leak over a server room or a stockroom is an emergency at any hour.
Managers also need paperwork. Every visit produces photos and a short written record of what was found and fixed, so the property file shows the roof's history when it is time to budget for replacement or answer a tenant.
Cost factors
What decides the cost of commercial roof work
Roof system and size
Membrane type, square footage and insulation set the base.
Drainage corrections
Tapered insulation and new drains add material and labor.
Rooftop equipment
HVAC curbs, skylights and penetrations each need flashing work.
Access and phasing
Working around an open business adds staging and scheduling time.
Commercial roofs are priced after a roof survey and, where needed, core samples to check the insulation.

Commercial leak response
When a commercial roof leaks, we answer any hour, stop the water with a temporary seal once the rain allows, and trace the entry point on the roof, not just above the ceiling tile that got wet. Common culprits are split seams, failed flashing at HVAC curbs, clogged drains and parapet caps letting water behind the membrane.
The permanent repair follows with matching membrane and a written note for the property file, including anything else on the roof that looked close to failing.
Commercial Roofing
Commercial reroofing
A commercial reroof is either a tear-off to the deck or, where the existing roof is dry and the code allows, a recover over it. We core the roof to check for wet insulation first, because a recover over wet insulation traps the problem. New systems are usually TPO or modified bitumen with tapered insulation to fix drainage, or metal on pitched commercial buildings.
The work is phased by section so the building keeps operating, and each section is dried in the same day.
Commercial Roofing
Retail, office and warehouse roofs
Each building type has its own priorities. Retail centers need work scheduled around customer hours and storefront access. Offices need noise and adhesive odors planned around tenants. Warehouses often have large roofs with many skylights, exhaust fans and long drainage runs, where a single clogged drain can pond water across a wide area.
We plan the staging, safety perimeter, crane or hoist location and schedule for the building in front of us, and agree it with the manager before work starts.
Your options
Repair, recover or replace a commercial roof
| Repair | Recover | Tear-off and replace | |
|---|---|---|---|
| When it fits | Local seam, drain or flashing problems | Dry existing roof, one layer, sound deck | Wet insulation, multiple layers or a failed deck |
| Disruption | Minimal | Moderate | Highest, phased by section |
| Drainage fixes | Limited | Possible with tapered insulation | Fully correctable |
| What we check first | The leak path | Core samples for moisture | Deck condition as sections open |
A sound roof with tired seams may also be a candidate for [[roof-coating|a roof coating]].

Roofing in Jacksonville
Commercial roofing under Jacksonville permits and summer rain
Commercial roof work in Jacksonville runs through the same online permit system as residential: every permit type is submitted through JaxEPICS, and a phased commercial reroof means planning each phase's inspections around that permit. The weather sets the rest of the schedule. NWS Jacksonville's normals put 21.25 inches of rain in June, July and August, so large tear-offs are sequenced to open only what can be dried in before the afternoon storms.
