EPDM (Ethylene Propylene Diene Monomer) and TPO (Thermoplastic Olefin) roofing are reflective, single-ply roofing membrane systems that are flexible and long lasting. EPDM and TPO are widely known for their durability and installation ease.

These single-ply "rubber roofs" use high-performance compounds that weather well in the area's snowy winters and hot summers. These systems fully adhere to the roof, and it is common for the roofing membrane to be exposed throughout the life of the roof.
