The Benefits of TPO Roofing

If you are currently evaluating your roofing options, and seeking to install an energy efficient, single ply roofing membrane, consider TPO (thermoplastic olefin) roofing. TPO is touted to have the advantages of PVC and EPDM roofing, without the drawbacks and extra expenses. This means that TPO roofing is as UV-resistant and as heat-resistant as EPDM, and as heat-weldable as PVC.

What is TPO?

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made of polypropylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.

The membrane is composed of three parts:

1. TPO polymer base.

2. polyester-reinforced fabric middle (scrim).

3. thermoplastic polyolefin compounded pinnacle ply.

Fillers commonly used in TPO production include, but are not limited to talc, fiberglass, carbon fiber, and wollastonite. Rubbers commonly used in TPO production include ethylene-propylene rubber and EPDM.

Benefits of TPO Roofing

TPO roofing remains a viable option for both residential and business owners, as it is relatively low in cost. On average, TPO roofing can cost anywhere from $5.00 to $7.50 per sq. ft. installed.


TPO roofing is incredibly effective in resisting bacteria, debris, algae, and dirt, as well as ultraviolet and chemical exposure. In addition to its high resistance to debris build-up, TPO’s flexible membrane allows it to withstand punctures, tears, and impact damage.

Simple Setup

Due to TPO’s lightweight and flexible properties, it is much simpler to install, as there as fewer seams. Less work and time spent on installing TPO translates into direct savings.

Energy Efficient

The energy efficiency of TPO roofing attracts many homeowners, as TPO roofing produces monumental savings on cooling fees, and is good for the environment. TPO’s white reflective surface exceeds the EPA’s energy star requirements and white, tan, and gray are indexed with the Cool Roof Rating Council. Installing a TPO roof on your private home or building will keep the indoor temperature comfortable on blistering summer days while reducing HVAC costs!
