What model year is your RV? At around 10 years old, it might be better to coat a roof that is in 'good' condition, or fair condition, rather than waiting like I did until it was 14 years old and in such poor condition that all the white stuff washed away when I was cleaning it and getting ready to coat it.
Try this stuff. It is as easy to apply as paint on a wall. A lot thicker, and does not run like paint. It took about 8 gallons to coat my 30' long RV.

Good luck,

That's what I put on mine. It worked great. Mine had been sitting in a tow yard for about 6 years and had developed leaks all over the place. I cleaned the roof and brushed this stuff on around every seam and protrusion through the roof. It's been a little over a year now and it's still as flexible as the day I brushed it on. I did find a couple of spots that I had missed and had to re-do. Putting the stuff in the freezer slows the curing process so you can dig it out later if need be. The warmer it is while you're working with it, the faster it will cure. Read the label to determine how much time you have to work with it once you add the hardener. I would definitely use this stuff again.
I only used a gallon on my 30-foot motorhome, but again just did seams and protrusions. It would have taken a lot more to roll it over the whole roof.
