TPO (Thermoplastic Polyolefin) is the fastest-growing commercial roofing membrane in North America, and for good reason. Its white reflective surface can reduce cooling costs by up to 30%, making it an excellent choice for Edmonton businesses looking to lower energy bills. TPO membranes are mechanically fastened or fully adhered and joined with heat-welded seams that are often stronger than the membrane itself. Marlex Roofing installs TPO systems to manufacturer specifications with precision welding equipment, ensuring airtight seams that will not delaminate over time.
TPO (Thermoplastic Polyolefin) is a single-ply commercial roofing membrane made from a blend of polypropylene and ethylene-propylene rubber. It is white or light-colored, highly reflective, and joined with hot-air-welded seams. TPO is the fastest-growing commercial roofing product in North America due to its energy efficiency, competitive cost, and ease of installation. It is well-suited for flat and low-slope commercial roofs.
TPO's white reflective surface reflects up to 80% of solar radiation, reducing rooftop temperatures and interior cooling loads by up to 30% in summer months compared to black EPDM or built-up roofing. For Edmonton commercial buildings with large roof areas, this translates to measurable annual savings on air conditioning costs.
With professional installation and regular maintenance, TPO roofing lasts 15 to 30 years. Manufacturer warranty terms vary from 10 to 30 years depending on the product and installation system. Marlex Roofing installs TPO to manufacturer specifications to ensure full warranty coverage.
TPO commercial roofing typically costs $8–$14 per square foot installed in Edmonton, making it one of the most cost-competitive single-ply systems available. Pricing depends on membrane thickness (45, 60, or 80 mil), insulation R-value, attachment method, and roof complexity. Thicker membranes carry longer warranties and are recommended for high-traffic or harsher-exposure roofs.
TPO is the better choice when energy efficiency, lower cooling costs, and heat-welded seam strength are priorities — especially for warehouses, retail centres, or any building with significant summer cooling load. EPDM is preferable when proven 40+ year longevity, sub-zero flexibility, and lowest lifecycle cost are the priority. Marlex Roofing assesses your building's exposure, HVAC load, and budget to recommend the right system.
A typical 5,000 sq ft TPO installation in Edmonton takes 3–5 working days, weather permitting. Larger projects of 20,000+ sq ft typically run 2–4 weeks. TPO is one of the faster commercial systems to install because of its lightweight rolls and hot-air-welded seams. Marlex Roofing coordinates scheduling to minimize disruption to building operations.
