First off you can get a 45 gallon bladder from places like Camping World to carry water up to your RV from town. Then use an RV water pump to transfer it to your RV holding tank. That same pump can then be used with a garden hose to wash off the roof.

I cannot tell you the pros and cons of washing the roof or not. I do know that the roofing membrane is extremely thin. My goal of washing is to ensure all the caulk is in good condition. I have been thinking about applying eternabond tape at all the seams so I do not have to worry about it ever again.

I wash mine with a carwash brush and Dawn blue dish soap, it works really well. I am surprised how black my roof is every time I wash it.

I like the idea of using the water from the pond. Pump it or carry 5 gallon buckets to a 55 gallon drum, let it sit over night to settle out any debris and then use the water to clean the trailer or other items.

If you get a fair amount of rain you might be able to use your TT’s rain gutters to fill a 55 gallon drum.

The manufacturer (DICOR) recommends Spic & Span and a stiff brush (not harsh) they also say no protectorants or inhibitors are needed.

IIRC, according to my roof (Alpha) documentation, the material has a UV inhibitor embedded in the material, so treatment for UV protection is not recommended.

Thanks for all the ideas so far.

One of the Utube videos I came across had a detailed procedure on cleaning. At the end they recommended using Aerospace 303 protectant.

The Dicor literature DOES recommend using their own protector after cleaning. Its a spray-on bottle and they say does not contain silicone, etc. Its for UV protection. That seems smart to me, whether you use a Dicor product or 303.

My pond is too far away to make carrying water practical. Why not just do a small area at a time with a bucket and brush and the wipe off with a rag? Grandpa used to wash his car that way without rinsing because we had a well and couldn't afford to waste water. If you are going to apply 303 afterwards anyway, seems like all that rinsing is overkill. Now, if a new rubber coating is to be applied., then I can see why thorough cleaning is necessary to promote adhesion.

Anyone here that's real lazy and hasn't cleaned the rubber roof in 20 years.....LOL.....and what are the results...

I wash the roof mostly to determine if there are any new holes or potential damage over the winter. I can also check all the seals. I agree it's not something to look forward to.

The black streaks is actually the natural process of chalking off the rubber. Clean or not, you will get black streaks. As far as I know, there is no regular maintenance other than checking the seams. You can clean it 4 times per year to check the caulk or simply install Eternabond tape as soon as you get the camper.

I bought my camper for fun, not additional maintenance. I applied Eternabond to my seams. My roof is 16 years old, I never washed it. We bought it used from my wife's uncle. He owned it for about 8 years... he never washed the roof either. All those sprays and products are completely unnecessary and not recommended by Dicor. They are simply products meant to remove money from your wallet.

By seams I mean where the roof meets the front and rear end caps and the side wall.

I don't see any seams on my roof. The rubber roof is one piece. The only holes are at the vents and antenna. They all seem to be well coated with a self-leveling compound.

The Jayco owner's manual is very clear about maintenance. All it says is to check the caulk around the vents and seal if necessary.

Yes, clean your roof to see what your seams look like, the cause of all rv roof leaksI use a cleaner/de-greaser, just a little water in a bucket to rinse off your rag.

The black streaks come down no matter what even on brand new perfectly clean trailers. Most of it is from the black sealant/caulk.
