TPO (Thermoplastic Polyolefin) is the fastest-growing segment of the commercial roofing industry. Its reflective white surface reduces cooling costs, while its heat-welded seams provide superior puncture and leak resistance. Capital City Roofing is a certified installer of major TPO manufacturers, offering systems backed by 20 and 30-year NDL warranties.
TPO is composed of three layers: a TPO polymer base, a strong polyester reinforced fabric center (scrim), and a thermoplastic polyolefin compounded top layer.
Reflects up to 88% of solar UV radiation, significantly reducing building cooling costs.
Seams are fused together using high-heat welding equipment, creating a bond stronger than the membrane itself.
Resistant to common rooftop chemicals, grease, and industrial pollutants.
High-strength polyester scrim provides excellent protection against punctures and tears.

Thermoplastic Polyolefin (TPO) has become the gold standard for commercial roofing in the Southeast, and for good reason. In cities like Atlanta, where summer temperatures frequently exceed 90°F, building owners face massive cooling costs. TPO's highly reflective white surface acts as a giant mirror, reflecting solar radiation away from the building rather than absorbing it through the roof deck. This 'cool roof' technology can reduce HVAC energy consumption by up to 30% compared to traditional black roofs like EPDM or Built-Up Roofing (BUR). Capital City Roofing specializes in the precision installation of TPO systems, using automated robot welders to ensure every seam is fused at exactly the right temperature and speed for a permanent, watertight bond. We offer a full range of thicknesses-45-mil for budget-conscious projects, 60-mil for standard commercial needs, and 80-mil for maximum puncture resistance and longevity.
With proper installation and maintenance, a 60-mil TPO roof typically lasts 20-25 years. 80-mil systems can last 30+ years.
White is the standard color because it offers the highest solar reflectivity, but TPO is also available in grey and tan for specific aesthetic requirements.
TPO offers better energy efficiency and stronger seams through heat welding, while EPDM (rubber) is better at handling extreme temperature fluctuations without cracking.
