Just as sure as someone "assures" you that your roof is TPO or EPDM, there will be that "ONE TRAILER" that Keystone manufactured with "the other stuff" and guess what: Yup, it's yours.......
That said, to be sure what kind of roof membrane is on your trailer, go to the most convenient roof vent, remove the 4 screws that hold the inside trim in place, pull the trim down and look at the roof membrane that is stapled around the hole where the vent is mounted from above. If the roof membrane is white/tan with a black backing, it's EPDM. If the membrane is the same color on top and bottom, it's TPO.
Most (well at least many) of us just use hot water, Dawn dish soap (the blue kind) and a splash of Clorox to scrub our roof. Be sure to keep the sides wet so it won't stain as it runs off (do that with anything you use on the roof) and then, wash the sides "from bottom to top" so it all stays wet until you're ready to rinse it off.
Aerospace 303 is my 'preferred" roof coating. I also use it on the FILON sidewalls, decals and the front cap. Good stuff and keeps things looking good, protected from UV and it even keeps the bugs from sticking.
