Tips& info about TPO/PVC roofs from Sonny the cow!

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 – It’s from the broad family of rubber roofing materials
  • 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 it
  • TPO and PVC can be installed over your current roof system in most cases
  • Both products normally meet Energy Star guidelines
  • 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
  • Be sure to hire a professional who is licensed, bonded, and insured to protect yourself

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!
