TPO membranes are created by calendaring with lamination, extrusion with lamination, or extrusion-coating techniques. Polypropylene and Ethylene Propylene polymers are blended and usually are reinforced with polyester to create TPO sheets. To achieve the desired physical properties, TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances.
TPO Roofing is relatively new in the commercial roofing market. TPO is designed to be the perfect combination of EPDM (rubber) and PVC (polyvinyl chloride) which is why it is one of the most popular roofing products available these days, despite its relative youth. Due to its advantages, TPO has quickly climbed the ranks in today’s market. It is flexible, strong and very resistant to harsh temperatures and wild weather. Although TPO roofing has many advantages, it lacks the long track record that more traditional roofing systems boast.

No plasticizers are involved in TPO roofing systems, they don’t degrade under UV radiation, and they come in white (which reflects heat, helping the building stay cool). Plus, they can be made from some recycled materials! TPO is the perfect choice for your “green” building.
Like all roofing systems, however, TPO does have some cons. Most of its shortcomings revolve around the fact that it is still so new. It doesn’t have the time-tested, reliable reputation that some other roofing systems can flaunt. Also, remember that the strength of any roof (TPO especially) depends greatly on the quality of 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.
