TPO Commercial Roofing

TPO polymers are blends or alloys of EBR (polypropylene plastic or polypropylene and ethylene propylene rubber) and EPDM (ethylene propylene diene terpolymer rubber). Other additives are added to the mixture before it is formed into a roofing membrane. The membrane is attached to the roof board with fasteners. When combined with several other elements (like a weathering package, fire retardants, and insulation), the TPO membrane becomes a part of an entire roofing system.

TPO membranes are produced by calendering with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets combine polypropylene and ethylene propylene polymers and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.

Although one of the newest types of commercial roofs on the market, TPO roofing has quickly climbed the ranks in the roofing industry. Designed to be the perfect blend of EPDM (rubber) and PVC (polyvinyl chloride), TPO is one of the most popular roofing products available these days, despite its not being out for two long. Its flexible, strong, and very resistant to harsh temperatures and wild weather, TPO roofing has many advantages, but it does not have a long track record that more traditional roofing systems boast.

TPO Roofing Systems

The strength, ease of installation, and longevity of TPO is what makes it so popular. It can be heat-welded during installation because of its thermoplasticity, which is a huge advantage since seams are usually the weakest part of a roof. In fact, TPO seams are 3-4 times stronger than EPDM systems and 6 times stronger than glue or tape based systems! They are resistant to chemicals, do well in hot and cold weather, and are generally quite affordable.  TPO systems can last 10-20 years with the right installation and maintenance. Lastly, if it is important that your roof is environmentally-friendly, TPO is a great choice.

TPO roofing systems contain no plastisizers, they don’t degrade under UV radiation, and they come in light colors (which reflects heat, helping the building stay cool). They can also be made from some recycled materials! TPO is the perfect choice for your “green” building.

Like all roofing systems, however, TPO does have some downfalls. Most of its shortcomings center around the fact that it is still such a new system. It doesn’t have the time-tested, reliable reputation that other roofing systems can flaunt. Also, remember that the strength of any roof (TPO especially) depends on the quality of installation. If you choose a reliable roofing contractor and take care of your roof with maintenance checks every year, you shouldn’t have any problems with a TPO roofing system.
