TPO, thermoplastic polyolefin, roofing material has many of the same benefits of roofing materials like EPDM and PVC, but it's more economical. Consequently, its use is growing in popularity in residential and commercial markets. Consumers should educate themselves on the material because TPO roofs can also have drawbacks. In addition to EPDM and PVC, Bergen County roofing experts also commonly install TPO membranes on area buildings.
A TPO roofing membrane is made from chemically binding rubber, ethylene and propylene, and fillers like talc, carbon filler and fiberglass are added. The fillers contribute to the membrane's strength and durability.
TPO membranes resist tears, impacts, dirt accumulation, punctures and mold growth, making them highly durable. Their flexibility allows for movement as a building settles, and they handle thermal expansion and contraction more efficiently than other roofing materials. The material also resists damage from ultraviolet rays, chemical exposure and the ozone. The strength of its welded seams far surpasses the strength of EPDM adhesive and tape seams.
TPO roofs are now available in white, light gray and black colors, enabling them to fit in well with different housing styles. They're also easy to install because they come in lightweight, wide sheets, which require less seams. Ease of installation translates into lower installation costs for consumers.
The reflective properties of TPO make this roofing system an ideal choice for energy efficiency.

It helps reduce energy waste and mitigates the heat island effect, saving consumers on heating and cooling costs. These membranes also do not contain chlorine, which is hazardous to the environment, and they're completely recyclable.
A major drawback to TPO roofing systems is the fact that their longevity is questionable. They're relatively new, and manufacturers are still trying to find an ideal chemical formulation for them. In some instances, these roofs have experienced issues with seam breakage, leaks and membrane failure, especially when exposed chronically to hot temperatures. Due to accelerated weathering in hot temperatures, TPO may not be the best choice for warm climates.
Consumers can take some precautions to increase their odds of purchasing a quality TPO membrane. They should buy only from manufacturers who have been around since TPO came about. These manufacturers are more likely to have a long lasting formulation.
Consumers should also purchase membranes that meet Energy Star requirements. Some manufacturers have not been around long enough to meet some of these requirements. Buying a membrane with a smooth surface is also helpful for energy efficiency.
The top ply of a TPO membrane should be thick, and seams should have been welded at high temperatures. Consumers should also try to obtain a warranty.
