TPO

Thermoplastic single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.  Suitable for a variety of low slope commercial roofing applications, TPO is a sustainable roofing solution for a wide range of building types.  As demand increases for heat-reflective and energy efficient roofing systems, thermoplastic polyolefin (TPO) single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.

TPO also offers design options with membranes available in reflective white, tan or gray, which can help reduce a building’s cooling requirements.  The flexible, hot-air welded membrane is available in 8’, 10’ and 12' widths.  Installation options include, mechanically fastened, fully adhered, and ballasted.

The drawbacks to TPO roofs are their fire resistance and limited sheet size.  While they can be part of a fire-rated system, the TPO membrane itself can be susceptible to fire.  The narrow-width sheets require more seams in the field, a common place for potential roof leaks.  However, unlike BUR/Modified roofs, TPO will withstand grease, standing water, and UV rays.

Depending on the thickness of the TPO membrane, insulation layers, deck type, and installation method, TPO warranties range from 10 years to 30 years.
