The System

Thermoplastic Polyolefin.
Single-Ply. Heat-Welded.

TPO (thermoplastic polyolefin) is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber. Installed in wide sheets across the roof surface, TPO's seams are fused together using hot-air welding guns — creating a bond that is actually stronger than the membrane itself.

As the fastest-growing commercial roofing system in North America, TPO delivers an exceptional combination of energy efficiency, durability, and value. Its bright white surface reflects solar radiation, reducing cooling costs and earning Energy Star certification. Its chemical resistance makes it ideal for restaurants, commercial kitchens, and industrial buildings.

The Material

The Membrane, Up Close.

Reinforced thermoplastic polyolefin over a polyester scrim core. The seam you see isn't glued — it's fused with 500°C hot air into a bond stronger than the sheet itself. That's why TPO fields stay monolithic for decades.

Advantages

Why Choose TPO.

Heat-Welded Seams
Hot-air welded seams create the strongest bond available in flat roofing. Unlike adhesive or tape-based systems, heat-welded joints are fused at the molecular level — they will not separate, peel, or degrade over time.
Solar Reflectivity
TPO's bright white surface reflects up to 85% of solar heat, significantly reducing cooling loads and energy costs. Energy Star certified and Cool Roof Rating Council listed for verified thermal performance.
Chemical Resistance
Resists oils, grease, animal fats, and a wide range of industrial chemicals without degradation. This makes TPO the preferred choice for restaurants, commercial kitchens, and food processing facilities.
Puncture Resistance
Reinforced with polyester or fiberglass scrim for exceptional tear and puncture resistance. TPO maintains its integrity under foot traffic, rooftop equipment, and construction debris.
Low Maintenance
Once installed, TPO requires minimal upkeep. Periodic inspections and basic debris removal keep the system performing at peak efficiency for decades.
Cost-Effective
TPO delivers the best value proposition in commercial flat roofing — competitive material and installation costs combined with energy savings and minimal maintenance create an unmatched lifecycle value.
Applications

Ideal For.

TPO excels on commercial and multi-family flat roof applications where energy efficiency, chemical resistance, and long-term performance are priorities.

Local Performance

TPO in the Okanagan.

The Okanagan Valley’s extreme conditions demand roofing systems that can handle punishing heat, heavy snow, and relentless freeze-thaw cycles. TPO is engineered to excel in all three.

❄
Freeze-Thaw Cycling
TPO’s thermoplastic composition maintains flexibility through Okanagan freeze-thaw cycles. Heat-welded seams create monolithic bonds that won’t separate as the membrane expands and contracts with temperature changes.
☀
UV & Sun Exposure
With 2,000+ hours of sunshine per year, Kelowna’s intense UV demands exceptional resistance. TPO’s white reflective surface bounces up to 85% of solar radiation, reducing roof surface temperatures and extending membrane life.
🌡
Temperature Extremes
Summer highs above +40°C and winter lows below −25°C put extreme thermal stress on roofing. TPO performs reliably from −40°C to +80°C, providing comfortable margin in every Okanagan season.
Common Questions

TPO FAQ.

A professionally installed TPO roof typically lasts 20–30 years. Membrane thickness, seam quality, and regular maintenance all influence longevity. Premium TPO membranes with proper installation often exceed manufacturer warranty periods.
Both are single-ply thermoplastic membranes with heat-welded seams. TPO is generally more cost-effective and offers excellent UV resistance, while PVC has superior chemical resistance. For most commercial applications in the Okanagan, TPO provides the best balance of performance and value.
Yes. TPO’s white reflective surface can reflect up to 85% of solar radiation, significantly reducing cooling costs. Many TPO products are Energy Star certified and contribute to LEED credits for sustainable building design.
TPO seams are heat-welded using hot-air welding equipment at temperatures between 400–600°C. This creates a homogeneous bond that is actually stronger than the membrane itself — the seam will not delaminate or separate over time.
Absolutely. TPO’s operating range of −40°C to +80°C easily handles Okanagan extremes. Its reflective surface reduces thermal stress in summer, while its flexible thermoplastic composition handles freeze-thaw cycling without cracking or splitting.
