Flex TPO

The Economical, Cost-Effective Roofing System for Long-Term Wear & Energy Savings


Roofing system


The Flex TPO thermoplastic single ply system is based on advanced polymerization technology that combines the durability and weatherproof properties of ethylene-propylene (EP) rubber with the heat-weldable capability of polypropylene. This membrane is specifically formulated for long-term weather resistance without the use of either polymeric or liquid plasticizers.

In addition, Flex TPO membranes will not host mildew, bacteria or algae, so that reflectivity remains high, helping reduce air conditioning loads and the urban heat island effect. They are also made without plasticizers or chlorinated compounds for a superior environmental roofing solution.

Flex TPO comes in wide sheets to help make installation faster and easier on new roofing and re-roofing applications, resulting in fewer seams and less material. Warranties are available for up to 20 years.
