Rubber Roof Cleaner and Protectant

Wet and Forget

That’s not what Winnebago recommends. “This rubber roof material does not require coatings to protect the surface from ultraviolet light or ozone.“

I didn’t use STP back in the day either.

Talked to Dicor (who makes most of the rubber roofs) at a Good Sam rally a few years ago. They recommended using their cleaner and protectant saying that the more expensive treatments are not needed.

I use Aerospace 303 Protectant on everything except the roof.

And, with all the rain, I don't think it will be necessary to clean the roof IF it ever stops raining. My roof looks pretty good.

I was given CamCo roof cleaner available at Walmart. It sat on the shelf for a long time, but then I went to clean the roof and didn't have my usual Spic & Span so I used it. Was not enthused while cleaning, but the rinse water was brownish. But when it dried, boy what a difference - very white and bright. Here is a picture I used for selling it taken after cleaning it and laying down caulk. I use a soft brush on a threaded pole.

Here is a photo of the rubber roof on my TT, discolored from weathering. It at least warrants cleaning - just hosing down is not an option. I'm still not sure if/what UV product to use afterwards.

Same here, IMO scrubbing and rubbing only shortens it's eventual life.
The only time I would do anything is if and when grass and weeds started growing from the dirt build up:W

That roof looks great and doesn't need a thing. LEAVE IT ALONE!!!!

Considering that you've had roof issues, I recommend and good cleaning and refresh of any questionable Dicor. Clean the area around where new Dicor needs to go with mineral spirits.

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.


With Superflex you do not need any treatment and the recommended cleaner is dish detergent. You may need something a little stronger from letting it go that long. Do not use Dicor on Superflex roof unless you want to bubble/wrinkle up the membrane. Their is a difference. Look in your doc packet for the roof membrane paperwork, then you'll know what you have.
