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
