What’s a TPO roof? A TPO, Thermoplastic Polyolefin, roof is a thin rubber like single ply roofing material for low-slope roofs. It’s been used on commercial and industrial roofs for quite a while now. It’s a great alternative to PVC, EPDM & Tar and Gravel or Built-Up Roof (BUR).
TPO roofs usually come in white, grey, and tan. They do have other colors. However, white, grey, and tan are the most used colors. Can a white TPO roof actually be green? How will it benefit your flat roof? We’re glad you asked.
How in the world can a white TPO roof be green rather than white? The benefits can be to both your building and the environment in money savings and being more environmental friendly. Probably one of the biggest benefits of installing a white TPO roof is the cooling costs of your building. Since it’s white, it will reflect heat rather than absorb it which, in turn, will reduce your cooling costs. White TPO will also reflect the suns UV rays rather than absorbing them making the roof more UV resistant which also makes your roof, potentially, last longer saving you money in repair and replacement costs.
Other ways that a white TPO roof is actually green:
- It stays flexible throughout it’s lifespan. Furthermore, that same flexibility allows for building movement which will reduce ripping or tearing.
- It meets and/or exceeds the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR specifications.
- It’s 100% recyclable. Most other roofing systems are not!
- It’s algae resistant.
- It’s chemical resistant. Think HVAC systems and such on the roof that have chemicals in/on them.
- Contains no chlorine.
- From an aesthetic point of view, since it’s a smooth installation it stays clean looking longer.
We have to deviate just a bit. Regardless of color chosen (white, grey or tan), TPO roofs are considered seamless since the bond is so strong. It can be bonded in 1 of 3 ways: mechanically attached, full adhered/heat welded or ballasted to the base surface of the roof itself. That not only makes stronger seams, but it also makes for a stronger roofing material that resists tearing, cutting and penetration. Since it’s considered seamless it’s also highly resistant to wind damage and offers better leak protection.
