Thermoplastic Polyolefin (TPO) is the leading and most preferred product in the commercial sector for its resistance to ultraviolet rays, installation advantages, LEED points and energy savings. TPO can be used in new construction and re- roofing applications. If the roof is sound, TPO can be used to eliminate the cost of a tear off and disposal of old roof. It can be mecahanically attached with screws and plates or adhered. Additionally, TPO is completely recyclable, so there is not waste on your project. It is available in a variety of colors, however, it is typically white or tan color. In turn, this saves costs in air-conditioning costs because less heat is transferred into the building.
