Let’s discuss TPO roof systems.

For commercial structures with a low incline or flat roof, TPO roofing stands out.


Affordability is one factor, but it doesn’t end there.

There are numerous other reasons to consider investing in a TPO roofing system.

You’ll grasp everything you need to know about TPO roofing, enabling an informed choice for your upcoming roofing project.

Different Membrane Systems

TPO is short for Thermoplastic Polyolefin. It’s a single-ply roofing membrane installed on flat or low-sloping roofs, often with engineered insulation.

The membrane varies in thickness, typically 40 to 80 mils or more, with quality differing among manufacturers.

Mechanical fasteners, adhesives, and heat welding secure the membrane, forming watertight seams around edges and penetrations.

TPO roofing systems aim to create a protective barrier against water, snow, and ice, ensuring the safety and dryness of buildings and their contents. Unique design requirements may apply, but the graphic below illustrates a common installation type.

Curious about TPO roofing material?

The single-ply TPO membrane comprises three layers bonded together for strength, flexibility, and impact resistance, incorporating polypropylene-based Thermoplastic Polyolefins.

These membranes may contain additives like EPR or EPDM rubber, talc, fiberglass, or carbon fiber for durability. Formulations include pigments, fire retardants, antioxidants, lubricants, and UV absorbers to enhance performance.

Benefits of a TPO Roof

A TPO roof provides notable advantages in key aspects:

Puncture Resistance

TPO excels in puncture resistance, minimizing the risk of leaks. Quality substrate design and installation are crucial for optimal performance.

Energy Efficiency:

Reflective TPO membranes in light colors enhance energy efficiency, reducing heat absorption compared to dark-colored EPDM. This leads to significant energy cost savings.

Value & Cost-effectiveness:

TPO roofing is a cost-effective solution, balancing performance and price. Its material flexibility and quick installation contribute to lower overall costs compared to alternatives like commercial metal roofing.

Long-term Weather Resistance:

TPO demonstrates superior resistance to prolonged heat and damaging UV rays, maintaining durability over time. Its resistance to shrinking ensures the longevity of seams and sealants.

Welded Seam Strength:

The strength of seams is crucial for a weather-tight roofing system. TPO's professionally-installed welded seams create a seamless membrane across the entire roof, ensuring reliability and longevity.

How to Select a TPO Roofing Installation Contractor

The successful installation of TPO roofing requires the expertise of a seasoned commercial roofing contractor, as it involves a specialized field demanding meticulous craftsmanship and strict adherence to manufacturer standards.

What are our customers saying about us

Our reroofing experience with S&S Roofing could not have been any better. Office staff was great with the scheduling, adjusted as I needed. They called the week before to confirm and everything was on time. They did a super job. A crew of 10 roofers arrived at 06:45, and were gone at 2:30pm. Looks like a new house. They cleaned up nicely. I would HIGHLY recommend the S&S Roofing Team.

S&S Roofing and Construction is awesome! Not only did the entire crew do an amazing job putting our roof on, but I got to meet Wesley The project manager, and Michael the owner. They not only did a fantastic job, they are two wonderful guys that obviously care about people. I couldn’t have asked for anything more, and I will be referring everyone I know to them. Thank you S&S for an incredible experience
