TPO roof systems are great for new construction or reroofing projects.  This lightweight single ply roofing system can be installed using a variety of methods depending on factors such as budget, location, warranty requirements and so on.  Unlike EPDM (rubber) TPO roofs utilize a heat weld at all seams, flashings and transitions instead of adhesive.  TPO roof systems are often white or gray but come in a variety of colors that may be considered for special projects.  Installation methods for TPO roof systems include the following:

  • Ballasted
  • Mechanically Fastened
  • Fully Adhered


TPO roof systems are measured by the millimeter thickness for warranty and expected duration periods.  The most common gages are as follows:

  • .045-MIL
  • .060-MIL
  • .080-MIL
