Rubber Roof Cleaner and Protectant

"The roof in the picture is not rubber. EPDM Rubber does not have a texture as in the picture. My bet would be it is Alpha Systems Superflex or possibly a TPO, but the texture sure looks like Superflex. I don't believe you ever mentioned the brand or year of trailer but most Thor and Forest River brands, Grand Design, Winnebago towables etc. use Superflex, and have for quite a few years."

I appreciate the feedback. My TT is a 2016 Winnebago Micro Minnie, I checked the owners manual, and it indicates the TT has a rubber roof, and just wash with a granulated household cleaner and water. Also to NOT use a UV protectant. But I am going to call Winnebago, give them the specific VIN number to confirm the roof material.

The Winnebago brochure claims it is TPO, but that's the current brochure, the 2016 brochure tells you little if nothing at all and neither mean a heck of a lot. I certainly would not trust the owners manual or brochure, and might not even trust what some factory phone rep claims. These companies change materials on a whim hence the disclaimers plastered on brochures and websites.

They usually give you a warranty sheet from the roof membrane manufacturer in the docs packet, which will tell you who made it and what it is. Dicor markets TPO also. One thing is certain and that is in 30 years of construction and having RVs I have never seen EPDM that has the texture shown in your prior pictures. EPDM is almost smooth other than on some you can see a thread pattern of the reinforcement layer under the white wear layer. It does not have a pebbled pattern. I was on our roof last night which is Alpha Superflex and the embossed texture is not pebbled like your pictures. The Superflex texture looks like some old bitty's crepey looking biceps. Rubber is a generic term in the RV Industry.
