TPO Commercial Roofing in Central Florida
Single-ply thermoplastic membrane — the most cost-effective long-life flat-roof system for Florida commercial properties.
TPO — The Modern Florida Commercial Flat Roof
TPO (thermoplastic polyolefin) is the modern default for Central Florida commercial flat roofs. Sun State Solar and Roofing installs and maintains TPO membrane systems for offices, retail centers, warehouses, restaurants, and industrial properties across Seminole, Orange, Volusia, and Lake counties. State-certified, fully insured.
TPO's appeal is straightforward: heat-welded seams create a continuous waterproof surface, the white reflective surface lowers building cooling costs (often meaningful in Florida), the membrane is lightweight enough not to overload existing structures, and the lifespan runs 20-25+ years with proper maintenance. For most Florida commercial flat roofs in moderate-to-large sizes, TPO is the go-to.
What's Included in a Sun State TPO Install
- Permitting and inspection coordination
- Existing roof tear-off (or prep for over-install where appropriate)
- New ISO insulation board to required R-value
- Cover board for puncture resistance
- Mechanically-fastened or fully-adhered TPO membrane (60+ mil)
- Heat-welded seams — the strongest commercial seam system available
- New flashing at all walls, drains, curbs, penetrations
- Drain ring replacement and overflow drain detail
- Manufacturer warranty + workmanship warranty
- Photo-documented work product for facilities records
TPO Maintenance & Service
TPO warranties typically require documented maintenance to remain valid. We offer quarterly and biannual TPO maintenance contracts that include seam inspection, drain clearing, sealant refresh, and a written report.
Is TPO Right for Your Building?
TPO is a strong fit for most moderate-to-large Central Florida flat roofs, especially where cooling costs matter. It's lightweight, which makes it a good candidate on older buildings where structural capacity is limited, and the white surface reflects the heat a dark roof absorbs.
It isn't always the answer. Where you want the longest service life from a traditional system, modified bitumen or BUR may be the better pick, and for long-hold buildings, commercial metal roofing lasts 40+ years. We compare the options at the estimate.
TPO Over an Existing Roof
Sometimes a TPO membrane can go over a single existing membrane in good condition, which saves tear-off cost. Code allows up to two roofing layers in most Florida jurisdictions, and the existing roof has to be dry, because wet insulation trapped under a new membrane causes problems later. We check existing condition and structural capacity before recommending an over-install versus a tear-off.
Common TPO Problems and Repairs
Most TPO leaks come from poorly welded seams, flashing at curbs and walls, and punctures from foot traffic or dropped tools during HVAC service. Seams can be re-welded and punctures patched with heat-welded TPO, so a localized problem rarely means a new roof. See commercial roof repair for leaks and storm damage, and commercial roof inspection if you need a condition report first.
Frequently Asked Questions
TPO (thermoplastic polyolefin) is a single-ply membrane roofing system used primarily on commercial flat roofs. The seams are heat-welded, creating a continuous waterproof surface, and the white surface reflects heat.
Properly installed TPO roofs last 20-25 years in Central Florida. Premium membrane thicknesses (60 mil and above) extend that further.
TPO is more energy-efficient than dark EPDM rubber and easier to install than modified bitumen torchdowns. For most Florida commercial flat roofs in moderate-to-large sizes, TPO is the modern default.
Sometimes — over a single existing membrane in good condition, with proper insulation and prep. We assess case-by-case during the inspection.
Commercial TPO is quoted per square foot. Pricing depends on building size, insulation requirements, deck condition, and access. Free estimates with detailed scope on every project.
Yes — quarterly or biannual TPO inspections including seam check, drain clearing, and sealant refresh. Critical for warranty preservation.
The best-known TPO membrane makers include Carlisle, GAF, Johns Manville, Elevate (formerly Firestone Building Products) and Versico. The installation matters more than the brand: seam welds, flashing details, and a membrane thick enough for the job. We install 60+ mil membrane and back it with manufacturer and workmanship warranties.
It depends on the system, size and deck condition. Typical installed ranges: TPO $6-11 per square foot, modified bitumen $5-9/sf, and BUR $7-12/sf. Insulation requirements, tear-off, deck repairs and access move the number. Every estimate is free, with a detailed scope.
