Replacing Your Roof With TPO

If your roof is too far gone for leak repair or restoration, then TPO could be a great choice for your new roof. Architects and engineers are predominately specifying TPO on new construction, and reputable manufacturers routinely offer NDL (no dollar limit) warranties. Additionally, installing quality TPO requires certified installers and which prevents part time roofers from installing projects they have no business quoting.

TPO (thermoplastic polyolefin roofing membrane) was invented and created by the DOW chemical company in the early 1990′s. TPO Roofing means are made from ethylene propylene rubber and are a combination of rubber and hot air welded seams. They have excellent resistance to ozone, are algae-resistant, environmentally friendly and safe to install. Further, TPO is highly tear resistant, resists impacts, and resists punctures with good flexibility to allow for building movement. TPO’s are available in white, light gray, and black with thicknesses of either 45 mils (.045″) or 60 mils (.060″).

TPO is highly heat reflective, fire resistant, and energy efficient. It also resists UV rays and dirt.
TPO roofs are considered cool roofs. A cool roof can be defined in many ways by people or by different municipal codes. But basically, a cool roof reflects and emits the sun’s heat back skyward without allowing it to pass into the building or home. The more sun it reflects and emits, the cooler the roof. The Cool Roof Rating Council, CRRC, maintains an online database of cool roof products. Some TPO roofs score high on the scale, some do not, so be advised.
