Thermoplastic Polyolefin (TPO) is a single layer of synthetic membrane used primarily in commercial roofing. Engineered to be highly heat-reflective, TPO provides an energy-efficient alternative to EPDM and PVC. Commonly installed on flat roofing systems, TPO represents the fastest-growing segment in the commercial roofing industry. Today, more than 40% of commercial and industrial buildings have TPO roofs.
At Rackley Roofing, we specialize in installing TPO membranes. Throughout Tennessee, we proudly hold a reputation among leading manufacturers and discerning customers for performing efficient, cost-effective, and expert TPO roofing applications. Because the TPO membrane has three distinct layers (a polymer base, a polyester-reinforced scrim, and a top ply), only trust a highly experienced roofing installer.
The Benefits Of TPO Roofing
Today, TPO roofing is a technologically advanced alternative to other roofing materials. Commercial building owners and property managers consistently depend on TPO membranes to protect their structures from all outside elements, including fire, UV exposure, moisture, hail, and wind. TPO roofing offers significant advantages, making it a worthwhile and ideal investment for your next commercial roofing project.
Affordability
Without sacrificing quality or performance, TPO roofing delivers an inexpensive price point that other roofing materials simply cannot match. Most commercial property owners save several thousand dollars by choosing TPO over similar options like PVC and EPDM. TPO stands as the preferred roofing alternative for commercial and industrial buildings.
Durability
Strongly resistant to tears and punctures, TPO roofing is known for better withstanding adverse conditions than other similar types of commercial roofing. It also possesses a Class 4 impact rating (the highest level possible). Consequently, TPO roofs more than hold their own when perilous weather conditions (including rain, sleet, wind, and hail) threaten.
Easy Installation
Lightweight by design, TPO membranes allow for efficient installation. Wide sheets result in fewer seams and less labor-intensive effort to connect and seal tight. TPO roofing can be installed with adhesive or direct fastening to the roof deck based on the customer’s needs and preferences. Easy installation generally means less labor expense.
Energy Savings
TPO membranes provide optimum heat-reflective properties that prevent internal heat buildup. Accordingly, during warmer months, buildings with TPO roofing experience a reduction in air conditioning usage compared to structures that use other roofing materials. Nearly all white or light-colored TPO membranes meet the EPA’s strictest ENERGY STAR qualifications.
Environmentally Friendly
Unlike many other types of commercial-grade roofing, TPO roofing does not contain environmentally hazardous chemicals like chlorine. TPO membranes blend various types of rubber rather than plastic or other non-renewable materials. Because TPO roofs are 100% recyclable, they do not pose any harmful environmental risk at the end of their lifecycle.
Fire Resistance
Most TPO roofing manufacturers add environmentally-safe fire retardant chemicals. High-quality TPO membranes generally achieve a Class A fire resistance designation from the UL Solutions (UL). With this added security measure in place, property owners and managers value TPO roofing to help achieve commercial property insurance savings.
Flexibility
Aesthetically pleasing, TPO roofing safely allows for thermal expansions and contractions. As a building moves and settles over time, TPO membranes remain resistant to cracking and tearing (even at the seams if properly reinforced). Because of its unique elastic properties, TPO membranes can be installed on most commercial buildings.
Longevity
Because TPO roofing has excellent water and moisture resistance, its expected lifespan exceeds most other roofing materials. Typically, TPO membranes last approximately 20-30 years if properly maintained. Even in environments with temperature extremes (hot and cold), TPO roofs offer flexibility that ensures prolonged durability and weather resistance.
Low Maintenance
According to the National Roofing Contractors Association (NRCA), routine commercial roof maintenance extends its life cycle from 30-100%. Unlike other roofing materials, TPO roofing requires less frequent maintenance due to its resistance to leaks and tears. Mildew, mold, and algae also possess little or no adhesion to the sleek TPO membrane.
UV Resistance
By design, TPO roofing demonstrates a remarkable ability to withstand prolonged exposure to ultraviolet (UV) light from the sun. The highly reflective nature of TPO membranes (generally utilizing light-colored palettes like whites, grays, and tans) ensures that sunlight does not easily penetrate or absorb into or through the surface of the roof or building.
