PVC Roofing Material

We are looking at replacing our current rubber roof with PVC. I've found a lot of great information, but none says if the white PVC will discolor over time. A lot of RV's today have the new PVC roof, so I was wondering what your experience is. Thanks.
  • All white roof coverings will discolor with age, sap, dirt etc. The “look” of my roof is unimportant to me...it’s water resistance is my concern, and with regular maintenance, it is.
  • If you are researching, check out TPO roofing. Be aware that it comes in multiple thicknesses. You want at least 60 mil. TPO is "heat welded"/bonded at all seams.

    Both PVC and TPO have a longer life than EPDM. Most experts will tell you that the maximum life of an EPDM roof is about 10 years, but often as little as 5 years. It should be replaced, not just re-coated.

    PVC is 15 years. Longevity on a TPO is anywhere between 10 to 20. Advantage, and a huge one for us, is that for a PVC, you do not have to clean it. We will rinse it off, but maintenance is not required.
