Frequently Asked Questions About TPO Roofing TPO roofing is Thermoplastic Polyolefin roofing.  It is composed of different material than other types of roofing.  It’s a synthetic rubber that is able to be fused together and seamed with two-sided tape or adhesive.  Some people are unfamiliar with this type of roofing and may have some questions.  Here are some common FAQs about a TPO roof. What Are the Benefits of TPO Roofing? TPO is mostly white roofing that offers valuable reflective qualities that other roofing materials can’t offer.  It reflects over 85% of the sun’s rays so that heat is not absorbed into the roof and brought into the building.  The membrane of the roof stays close to ambient temperatures which is an added benefit for energy efficiency.  Because of the uniqueness of a TPO roof sealing system, it is one of the most reliable systems on the market currently.  Seams fused together are six times stronger than glue or tape systems.  Then a rubber roof system is laid out over the seams, making them virtually impossible to deteriorate.  Seams are most often the weakest part of a roof, so to have a seam system that is top notch is a huge benefit of a TPO roof. How Can TPO Be Installed? Different types of TPO installations include a fully adhered, ballasted applications, or mechanically attached type systems.  The most common type of TPO roof installation system is a mechanically attached roof system. What About My Existing Roof?  Can TPO Be Installed Over the Top? While a TPO roof is an amazing product, it is not a fix-all solution for your roof.  It is still recommended that you follow best practices when it comes to updating your roofing system.  Damaged roofing should be removed before a TPO roof is installed.  After the current roofing system has been inspected and problem areas repairs, it is then okay to go ahead and install TPO over the top of the existing roof after an insulation board has been installed.
