Our unit is 9yrs old this March and over the years I have washed the roof 2-3 times each year. At first a bucket car wash soap would get it looking new. Then after a few years I purchased Camco RV roof cleaner and another combo cleaner/protectant sold at Camping World. Eventually by year five or six the roof would not look new, dull off whitish grey and small dirt spots. I notice under a few vents it looks pretty new BUT what concerns me most is this wearing I described above. A small Crepe Myrtle tree branch also wore some of the top coat in a very small area.
Is there a top coating available ? We live in a severe dirt and dust area and also close to Interstate 5. I mean real close.
I had a wilderness with that same issue.
On my computer at home i have a lot of good info about fixing this.
There where 2 types of roofs rv mfg used like this. Using the wrong stuff will cause vulcanized.
One type was called alpha , thats what i had.
Cant remember the other type.
You need to find out what type you have from the mfg. I called wilderness and gave them my vin. They told me I had the alpha. A dealer try to sell me some stuff, later I learned what they were selling was the stuff not to use.
If its a alpha here's a good link. This is where I got the primer and top coat.

I think they sell products for both types.
