Pros and Cons of TPO Roofing

Updated: Jan 4

One of the fastest-growing roof types for flat roofs, particularly on commercial buildings, is TPO roofing. This inexpensive, thin roofing material is gaining popularity amongst building owners that want a durable, reflective roof, that won’t break the bank.

What Is a TPO Roof?

TPO stands for thermoplastic polyolefin, a single-ply roofing membrane that covers the surface of the roof. The name is a bit misleading because rather than being a plastic, TPO is actually one of a few different types of rubber, usually a blend of polypropylene and ethylene-propylene rubber.

TPO Roofing Pros

The biggest positive to installing TPO roofing on your flat roof is the cost. TPO is one of the cheapest materials on the market today, costing less than EPDM or other types of rolled rubber roofing. The other biggest positive of using TPO is its color. This type of roofing is white on top, which can help to reflect the sun’s light and stop heat buildup within the building.

TPO Roofing Cons

Unfortunately for those that are looking into TPO roofing, the list of cons far outweighs the positives. While it is inexpensive and white, different manufacturers of TPO products can make wildly different products.

Opting for TPO

If you choose to purchase a TPO roof, put your research into the manufacturer to find one that has a warranty or track record that can hold up over time.
