TPO (thermoplastic polyolefin) roofing is single play reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together.

TPO roofs are generally installed by mechanically attached systems. This system uses fastening plates to secure the membrane. This system provides faster installation times without the use of adhesive and seam tapes. It allows the white membrane of the roof to remain exposed throughout the life of the roof.

TPO roofs also have environmental benefits, as it is energy efficient and one hundred percent recyclable.

TPO roofs were originally developed in the 1980’s, in an effort to find a more economical and efficient roof to replace PVC and EPDM roofs. EPDM roofs were not weldable, and PVC roofs used liquid plasticizers, which made it brittle shortly after being installed.

The first TPO roof was installed in 1986, in Michigan. This single ply roof consists of a thermoplastic polyolefin membrane. There are three layers to this membrane: the TPO polymer base, the polyester reinforced fabric center (scrim), and the thermoplastic polyolefin compounded top ply. Common fillers include talc, fiberglass, carbon fiber, wollastonite and Metal Oxy Sulfate. Common rubbers used are ethylene-propylene rubber and EPDM.

There are many advantages to having a TPO roof. One of the best reasons is that it is so economical. TPO roofs are very popular, yet very reasonable. It can fit several different building styles, because it comes in white, light gray, and black (however a white roof is best for energy saving, because it reflects the sun so well).

TPO roofs are durable; it resists mold, dirt, tears, impact, and punctures. TPO roofs are relatively easy to install for a professionally trained roofer. TPO comes in lightweight, wide sheets. It takes less time and less work to install, meaning you save money.

TPO roofs are energy efficient, too. The white sheets help to reflect the sun off of your building, so that it will not be necessary for you to invest additional money to cool your building.

TPO material allows for the expanding and contracting that comes along in the winter months, making it an especially good roof for cold weather areas. Here's why you should consider TPO roofing.
