Thermoplastic Polyolefin single-ply roofing for energy efficiency
This roofing material can be fully adhered, mechanically fastened, or blasted. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems. This is a popular choice for "Green" building.
It is available in white, gray, and black. Using white roof material helps reduce the "heat island effect" and solar heat gain in the building..
