Full commercial flat and low-slope roof replacement across Tampa Bay in TPO, modified bitumen, and metal for retail, office, multi-family, and HOA buildings, with minimal downtime.
Every commercial roof replacement we do, built to last.
When a commercial flat or low-slope roof is past patching, replacing it is a business decision, not just a building one. We handle commercial roof replacement across the Greater Tampa Bay metro, including Hillsborough, Pinellas, Pasco, Sarasota, Manatee, and Polk counties, for retail centers, office buildings, multi-family properties, and HOA communities. Our crews install GAF EverGuard TPO, modified bitumen, and standing seam or exposed-fastener metal systems built for Florida heat, UV, and hurricane season. As a family-run, honesty-first contractor, we tell you straight whether a full replacement is justified or whether targeted repairs buy you more time. Every finding is photographed, every estimate is itemized, and the work is scheduled in phases so tenants stay open and dry. Our name is our promise, and that holds on a 40,000 square foot roof the same as on a house.
Commercial Roof Replacement in Tampa Bay: what homeowners should know
Commercial roof replacement built for Tampa Bay buildings
Commercial roofs fail differently than houses. A flat or low-slope membrane on a retail center, office building, or multi-family property takes the full force of Florida heat and UV all day, then sheds water across a wide, nearly level surface that drains slowly. Over time seams open, flashing pulls away, and ponding water works on the weak spots until patching stops keeping up. When that happens across most of the roof, replacement is the responsible move, not another round of repairs.
We replace commercial flat and low-slope roofs across the Greater Tampa Bay metro, including Hillsborough, Pinellas, Pasco, Sarasota, Manatee, and Polk counties. Our crews install GAF EverGuard TPO, modified bitumen, GAF LIBERTY self-adhered, and Mule-Hide low-slope systems, plus standing seam and exposed-fastener metal for owners who want a roof that lasts decades. Every system we install is matched to the building, the drainage, and the budget, not pulled off a shelf.
Before any of that, we tell you the truth about whether you even need a new roof. If your membrane has good years left, you will hear that from us, and we will quote the commercial roof repair instead. Honest, repair-versus-replace guidance is how we have built the business, and it is why our name is our promise.
Choosing the right commercial roofing system
The most common commercial replacement is single-ply TPO. GAF EverGuard TPO is a reflective white membrane that bounces heat off the roof, which matters in Florida where cooling costs run high. It welds at the seams for a continuous watertight surface and performs well on the wide, low-slope decks typical of retail and office buildings. Modified bitumen is another proven low-slope option, especially where a building has a history of foot traffic or wants a more robust multi-layer system.
For owners who plan to hold a building long term, metal is worth a serious look. Standing seam metal can last 40-plus years and handles Florida heat, UV, and hurricane-season wind better than almost anything else, which is why it often pencils out as the lowest cost per year of service. We also install exposed-fastener metal in 5V crimp and R-panel profiles where the budget is tighter. You can read more on our metal roofing page.
We do not push the most expensive option. We lay out lifespan, energy performance, wind rating, and cost side by side so you can make the call that fits the building and how long you plan to own it. No high-pressure sales, just the numbers and our straight recommendation.
Phasing the work around your tenants
A house can be torn off and reroofed in a day or two. A commercial roof over occupied space cannot work that way, and trying to force it leads to leaks into active units and angry tenants. That is why we phase commercial replacements section by section. We sequence the tear-off and install so each area is dried in before we move to the next, and we schedule around business hours, deliveries, and parking so storefronts stay open and units stay dry.
Property managers and HOA boards get a written phasing plan up front showing which section is worked when, plus a single point of contact for the duration of the project. We document decking, fasteners, flashing, and finished work in photos as we go, which gives you a clean record for reserve studies, owner communication, and warranty registration. Clear communication is not an add-on for us, it is how we run every job.
For larger multi-tenant or HOA roofs, phasing can stretch a project over several weeks, and we are honest about that timeline in the proposal. The trade-off is that your tenants stay in business and your building stays protected the entire time.
Permits, code, and the 25 percent rule
Commercial roof replacement requires a permit, and the specifics vary by county across our service area. We pull the required permit and handle the inspections so the project is fully documented and signed off. Working with a licensed Florida roofing contractor, license CCC1334243, means the paperwork is right and the work passes.
Florida code matters more than most owners realize. The 25 percent rule generally provides that if more than a quarter of a roof section is repaired or replaced within a year, that section has to be brought up to current Florida Building Code rather than simply patched back to its old condition. On a large commercial roof, a major repair can trip this threshold and effectively turn into a replacement anyway, so it pays to understand it before you spend on a half measure.
We install to current Florida Building Code and to manufacturer specification as a GAF Certified and TAMKO Pro Gold contractor. That combination is what lets your new roof pass inspection and qualify for the full manufacturer material warranty, backed by our workmanship warranty in writing.
Cost, financing, and insurance documentation
Commercial pricing is driven by square footage, the system chosen, deck condition, drainage, and access. As a planning range, flat and low-slope systems such as TPO, EPDM, and modified bitumen typically run $6.00 to $10.00 per square foot installed, standing seam metal $10.00 to $16.00, and exposed-fastener metal $8.50 to $11.00. Steep pitch or roof complexity adds about $0.25 per square foot, and each extra tear-off layer adds about $0.50 per square foot. Skylights are priced per item at the on-site inspection. You can get a quick starting figure from our instant roof estimate.
Big commercial projects are easier to budget with the right financing. We work with GreenSky for credit-based financing and Ygrene for PACE financing that is repaid through the property tax bill, which can be a strong fit for commercial and HOA properties. Our financing page walks through the options.
If your roof was damaged by a storm, here is exactly what we do and do not do. We are licensed roofers, not public adjusters, so we do not file, negotiate, or manage claims. We inspect, photograph, and provide an itemized estimate you submit to your carrier. You stay in control of the claim and your insurer makes the coverage decision under your policy. That documentation support, covered in depth on our insurance documentation support page, gives your carrier a clear, evidence-backed picture of the damage.

After receiving quotes for several roofing companies, I decided to go with a company other than Integrity Roofing of Florida. My decision was primarily based on the fact they were referred by a friend and offered a slightly lower cost. After six months, my roof was still not complete, and to make matters worse, my roof was leaking. I called Bettina at Integrity Roofing, and she determined that the company I had contracted with was not fully licensed and could not even pull a permit. I am so thankful to Bettina and the staff at Integrity Roofing. They took over the job, pulled the permit, and had the roof completed in a matter of days.

My roof suffered damage during Hurricane Milton. Multiple roofing companies came out and the quotes were outrageous. Some were even pressuring me to open a claim against my home insurance for the minor damage. I really enjoyed working with Integrity Roofing of Florida due to the exceptional customer care and great level of communication. They gave me a fair price and completed the work in a timely manner. Highly recommend them for your next home project.

As a realtor in the Tampa Bay Area, I have had the opportunity to work with many roofing companies. However, I decided to use Integrity Roofing to replace my own roof as I have personally seen the quality work they have done for my clients. As picky as I tend to be, I was very happy and greatly satisfied with the end result. My roof looks beautiful. I will definitely continue to refer Bettina Savorelli and Mike Sheppard with Integrity Roofing to all of my clients.
Common questions
Commercial Roof Replacement FAQs
How much does commercial roof replacement cost in Tampa?
Flat and low-slope systems such as TPO, EPDM, and modified bitumen typically run $6.00 to $10.00 per square foot installed. Standing seam metal runs $10.00 to $16.00 and exposed-fastener metal $8.50 to $11.00 per square foot. Commercial pricing depends heavily on square footage, deck condition, drainage, and access, so the on-site inspection sets the real number. Get a head start with our instant roof estimate.
What roofing systems do you install on commercial buildings?
For flat and low-slope commercial roofs we install GAF EverGuard TPO, modified bitumen, GAF LIBERTY self-adhered, and Mule-Hide low-slope systems. For buildings that want a longer-lasting option we install standing seam and exposed-fastener metal in 5V crimp and R-panel profiles. We match the system to your building, drainage, and budget.
Can you replace the roof without shutting down my tenants?
Yes. That is the point of phasing. We sequence the work section by section and schedule around business hours, deliveries, and parking so storefronts stay open and units stay dry. Property managers get a clear plan up front showing which area is worked when.
How long does a commercial roof replacement take?
It depends on square footage, the system, and phasing. A small single-tenant building can be a few days, while a large multi-tenant or HOA roof phased around occupants can run several weeks. We give you a realistic timeline in the proposal and keep you posted as each phase finishes.
Do you handle my insurance claim?
We are licensed roofers, not public adjusters, so we do not file or negotiate claims. What we do is inspect, photograph, and provide an itemized estimate you submit to your carrier. You stay in control of the claim and your insurer makes the coverage decision under your policy. See our insurance documentation support page for how that works.
What warranty comes with a new commercial roof?
You get the manufacturer material warranty on the system installed, which generally runs from roughly 20 to 50 years depending on the product and membrane, plus our workmanship warranty in writing. As a GAF Certified and TAMKO Pro Gold contractor we install to spec so the full manufacturer coverage applies.
Do you offer financing for commercial roof projects?
Yes. We work with GreenSky for credit-based financing and Ygrene for PACE financing that is repaid through your property tax bill. PACE in particular can be a fit for commercial and HOA properties. See our financing page for the options and how to apply.
Should I repair or replace my flat roof?
If the membrane is sound and the problem is localized, repairs are usually the smarter spend, and we will tell you that. Replacement makes sense when leaks are widespread, seams are failing across the roof, ponding is chronic, or the system is near the end of its service life. Our inspection and photos make the call clear.
Why does ponding water matter on a commercial roof?
Standing water that sits for days accelerates membrane breakdown, finds weak seams, and adds weight. On Florida flat roofs after heavy summer storms it is one of the most common drivers of premature failure. During replacement we address drainage so water moves off the roof the way it should.
What is the 25 percent rule and does it apply to my building?
Under current Florida Building Code, if more than 25 percent of a roof section is being repaired or replaced within a year, that section generally has to be brought up to current code rather than just patched. On commercial roofs this often pushes a large repair toward a full replacement, which we explain during the inspection.
Do you pull the permits for commercial roof work?
Yes. Commercial roof replacement requires a permit, and requirements vary by county across Hillsborough, Pinellas, Pasco, Sarasota, Manatee, and Polk. We pull the required permit and handle inspections so the project is fully documented and code-compliant.
Do you work with property managers and HOA boards?
Regularly. We give boards and managers an itemized proposal, a phasing plan, and photo documentation suited to budgets, reserve studies, and owner communication, with a single point of contact throughout the job. Clear communication is part of how we run every project.
Is metal a good choice for a commercial building in Florida?
Often, yes. Standing seam metal can last 40-plus years and stands up well to Florida heat, UV, and wind, which makes it a strong long-term value for owners who plan to hold the building. We also install exposed-fastener metal in 5V crimp and R-panel where budget is the priority. See our metal roofing page for details.
Can the My Safe Florida Home program help with my project?
That program is geared toward owner-occupied homes rather than commercial buildings, so it usually does not apply to a commercial roof. We support My Safe Florida Home on the residential side and can point you to the right path. For commercial buildings, financing through GreenSky or Ygrene is typically the better fit.
Do you also offer commercial roof repair and inspections?
Yes. If you are not ready for a full replacement, see our commercial roof repair and commercial roof inspection pages. We will give you an honest assessment of where your roof stands and what it actually needs.
