TPO Commercial Roofing

TPO polymers are a combination of EBR (polypropylene plastic or polypropylene and ethylene propylene rubber) and EPDM (ethylene propylene diene terpolymer rubber). Additional products are included in 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 are a blend of 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. Designed to be the perfect combination of EPDM (rubber) and PVC (polyvinyl chloride), TPO is one of the most popular roofing products available these days, despite its relative youth. Flexible, strong, and very resistant to harsh temperatures and wild weather, TPO roofing has many advantages, but it does lack the long track record that more traditional roofing systems boast.

TPO Roofing Systems

TPO is well-known because of its strength, ease of installation, and longevity. It can be heat-welded during installation because of the material’s thermoplasticity, which is a huge advantage since seams are usually the weakest part of a roof. In fact, TPO seams are thought to be 3-4 times stronger than EPDM systems and 6 times stronger than systems that use glue seams or tape systems! They are resistant to chemicals, do well in high heat, are flexible in cold temperatures, and are generally quite affordable. With proper installation and maintenance, TPO systems last anywhere from 10-20 years. TPO is also environmentally friendly!

No plasticizers are involved in TPO roofing systems, and the roof wont degrade under UV radiation. The roof comes in white, which reflects heat, helping the building stay cool. The roof can also be created from some recycled materials! TPO is the perfect choice for your “green” building.

Like all roofing systems, however, there are some downsides to TPO. Most of its shortcomings center around how new the system is. It doesn’t have the time-tested, reliable reputation which other systems can boast about. Remember that the strength of any roof (TPO especially) depends almost entirely on the quality of the installation. If you choose a reliable roofing contractor and take care of your roof with yearly maintenance checks, you shouldn’t have any problems with a TPO roofing system.
