Commercial TPO Roofing
Thermoplastic Polyolefin (TPO) is the #1 choice for commercial flat and low-slope roofs across the Southeast — and for good reason. Its white reflective surface cuts cooling costs by 20-30%, heat-welded seams create watertight bonds stronger than the membrane itself, and warranties extend up to 30 years. Kaliber Roofing brings expert commercial TPO installation to Charlotte, Indian Trail, and all of North Carolina.
Why TPO for Your Commercial Building?
TPO is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber. It reflects up to 90% of UV rays, dramatically reducing roof surface temperatures and HVAC strain. Available in 45-mil, 60-mil, and 80-mil thicknesses, TPO systems can be mechanically attached, fully adhered, or ballasted — giving your building the perfect configuration for NC's hot summers and severe storm season. It's also 100% recyclable, qualifies for ENERGY STAR® certification, and can earn LEED credits.
Cost-Effective Commercial Roofing
TPO membrane materials run $1.75–$3.75 per square foot depending on thickness, with complete installed systems ranging from $4.50–$10.00 per square foot including insulation, labor, and flashing. For a typical 10,000 sq ft commercial building, expect $45,000–$100,000 for a full TPO system with a 20-30 year warranty. That investment pays for itself through energy savings — most building owners see 20-30% reductions in summer cooling costs, which adds up to thousands annually in the Charlotte heat.
Buildings We Service
We install TPO on all types of commercial structures: office buildings, retail and shopping centers, warehouses and distribution facilities, medical clinics and dental offices, schools, churches, restaurants, hotels, and mixed-use developments. If it has a flat or low-slope roof in the Charlotte metro area, we can protect it with TPO.
TPO vs. Other Flat Roof Systems
Compared to EPDM (rubber roofing), TPO offers far superior energy efficiency with its reflective surface and stronger heat-welded seams vs glued joints. Against PVC, TPO delivers similar performance at a lower price point. And versus traditional built-up roofing (BUR), TPO installs faster with less disruption to your business, lasts longer, and is fully recyclable. For North Carolina's climate — hot summers, occasional severe storms — TPO delivers the best value.
Our Commercial Installation Process
We start with a comprehensive roof inspection including moisture scans, core samples, and drone photography — full report within 48 hours. Then we deliver a detailed line-item proposal with membrane options, insulation specs, warranty tiers, and projected energy savings. Our certified crews install your TPO system with heat-welded seams, proper flashing, and code-compliant drainage. We finish with a third-party quality inspection, manufacturer warranty registration, and your maintenance schedule. Minimal disruption to your business operations throughout.
Warranty Protection
We offer manufacturer warranties from 15 to 30 years (non-prorated options available) plus our own workmanship guarantee. NDL (No Dollar Limit) warranties are available for larger commercial projects. Heat-welded TPO seams are the strongest in the single-ply category — they won't peel or blow off. 80-mil TPO with mechanical attachment meets FM Global and UL wind uplift ratings for high-wind zones in the Southeast.

Frequently Asked Questions
How long does a commercial TPO roof last?
A properly installed TPO roof lasts 20 to 30 years depending on membrane thickness, installation quality, and maintenance. Our 60-mil and 80-mil systems routinely hit 25-30 years in NC conditions.
How much will TPO save on my energy bills?
Most commercial building owners in the Charlotte area see a 20-30% reduction in summer cooling costs. TPO's reflective surface can reduce roof surface temperatures by 50-60°F compared to dark roofs.
Can TPO be installed over my existing roof?
In many cases, yes — if your existing roof has only one layer and the deck is in good condition. This "recover" approach saves on tear-off costs and installs faster. We'll assess this during your free inspection.
How long does commercial TPO installation take?
A typical 10,000–20,000 sq ft installation takes 1-2 weeks depending on weather, complexity, and whether tear-off is needed. We coordinate closely with your operations to minimize disruption.
Is TPO good for North Carolina storms?
Absolutely. TPO's heat-welded seams are the strongest in the single-ply category. 80-mil TPO with mechanical attachment meets FM Global and UL wind uplift ratings for high-wind zones in the Southeast.
What warranty options are available?
Manufacturer warranties from 15 to 30 years (non-prorated available) plus our 10-year workmanship warranty. NDL (No Dollar Limit) warranties available for larger commercial projects.
Do you handle commercial roof repairs too?
Yes — we repair all types of commercial roofing systems, not just TPO. Leaks, ponding water, storm damage — we'll diagnose the issue and provide repair options before recommending a full replacement.
What areas do you serve for commercial roofing?
The entire Charlotte metro and surrounding areas including Indian Trail, Monroe, Matthews, Mint Hill, Weddington, Stallings, Waxhaw, Concord, Huntersville, and all of Union and Mecklenburg counties.
