Yes, most probably EPDM. The sales literature for my 2014 Big Country lists TPO as the roofing material. Before doing any re-caulking and cleaning I wanted to know for sure. In doing some research I learned that EPDM has a black backing and TPO does not. I removed one of the roof fan covers to find a piece of roofing to check the bottom side. It was black. I'm now assuming my roof is EPDM. Could someone verify that only EPDM has the black backing? Thanks.
