EPDM or TPO ?


    It is the utmost importance to determine your roof membrane type before applying Superior RV Liquid Roof Coating.
    HOW TO DETERMINE YOUR ROOF TYPE 
  • To determine which one you have, go inside the RV and unscrew the trim (garnish) under a ceiling vent and carefully remove it.
  • This should expose a bit of the roof membrane as they typically fold it into the vent cavity and staple it to the sides of the hole when they build the trailer.
  • Remove a staple and look underneath the rubber.
  • If it is black underneath and white on top, it is EPDM. 
  • If it white on both sides, it is TPO.
  • If it has an "orange peel texture" on top or a fabric backing DO NOT apply this product if it is a SUPERFLEX TPO or DIFLEX II roof membrane.
