TPO (Thermoplastic Polyolefin) roofing is a high-performance, single-ply membrane system commonly used on commercial and industrial flat roofs. Engineered for strength and energy efficiency, TPO offers excellent resistance to UV rays, heat, and chemical exposure, making it one of the fastest-growing roofing solutions in the industry.

This white reflective roofing membrane is specifically designed to reduce energy consumption by minimizing heat absorption. Its energy-efficient properties often help building owners meet or exceed commercial energy codes and may qualify for LEED credits or utility rebates. Available in standard thicknesses such as 45 mil, 60 mil, and 80 mil, TPO membranes are both lightweight and durable, supporting long-term performance without adding unnecessary load to the structure.

TPO roofing systems can be installed using fully adhered, mechanically attached, or heat-welded techniques. Heat-welded seams are a standout feature of TPO systems—they create a strong, watertight bond that resists leaks and moisture intrusion. In addition to being highly resistant to punctures and tears, TPO membranes are also designed to accommodate building movement and temperature fluctuations without compromising their integrity.

Maintenance requirements are minimal. Routine inspections and surface cleaning are usually enough to keep the system performing well. Seams and flashings should be checked periodically, especially after severe weather, to ensure a watertight seal throughout the roof’s service life, which typically ranges from 20 to 30 years.
