Determining what your RV roofing material is can be done in just a few easy steps. First find an overhead roof vent, unscrew and take off the vent trim ring and find a section of the roofing material. Take out a staple to check the back side. If the front is one color but the back is black, you have an EPDM roof, but if both sides are the same color, you have a TPO roof.
