TPO/PVC is a great choice for flat roofs that come with big warranties. But there are a few things that you should know about your TPO/PVC roof!
TPO stands for Thermoplastic Polyolefin, and PVC stands for Polyvinyl Chloride – it is similar to vinyl pipes but flexible for a roof! The edges overlap and are heat welded together to ensure water does not get in. White material will have the biggest impact on energy efficiency. The cap sheet can come in a variety of colors and designs. Warranties can be issued for as long as 35 years. The idea is for the seams to be heat welded, turning a lot of sheets into one big sheet
Both of these roofs are extremely durable and long lasting. Penetrations, seams and AC units on the roof are the most susceptible areas for a leak to occur. Your roof should be cleaned before and after monsoon season, especially if you have trees of any kind where debris can cause blockages in the way water drains. TPO/PVC can either go over the current roof or we can tear off and dispose of the old roof and then inspect substrate for bad wood. At the very least, a base sheet (underlayment) is applied under the TPO/PVC, but you can add insulation or other materials to create a more in-depth roofing system.
When installing the TPO/PVC, we screw the material down every 6” to 12” depending on the manufacturers’ specifications. The seams are heat-welded together and caulk is applied to any areas that need it. Clean up and touch up work is all completed to ensure a professional job done by Arizona Roofing Systems!
