What You Should Know About TPO Roofing

TPO roofing

Thermoplastic polyolefin or TPO is a durable roofing material made from ethylene-propylene and a variety of fillers. These materials include carbon fibers, talc, and fiberglass. The material is then rolled out into a three-layer system. The base layer is made of the same material as the top layer.


When considering TPO roofing, you need to consider the cost of installation. The average cost is $2 to $4 per square foot, but the price can be as high as $11 per square foot for steep-sloped roofs. Additionally, you will need flashing, which will keep water from getting underneath the roofing. These materials add about 5% to the overall cost of TPO roofing.

The thickness of the TPO roofing membrane varies from 45 to 60 inches. A thicker TPO roofing material offers more protection against UV rays, puncture resistance, and durability. The material is available in several colors, but will cost more if you want it in a color other than white. Common colors that are available without an additional fee are white, tan, and grey. TPO roofing installation is a specialty flat roofing material, and you may need a trained roofer to complete the job properly.
