X3. Zinger has a walk on roof, but still spend as little time up there as possible.
I use ProtectAll cleaner/conditioner from CW. Works well. Black streaks can be a pain! I used RV wash and occasionally Magic Eraser on our 2012 and it worked well.
Keeping roof (and esp. gutters) clean is best measure.

If I remember right, the literature that came with our rig said not to use any conditioners on the roof. All that was needed was cleaning.
Have they changed their stance on this?
The gentleman that walked us through our PDI said the roof would need washed and conditioned 2 x a year, is this not correct?
I agree, there has to be break even point to excessive washing with even the most gentle detergents. All cleaners are chemicals, so they all aid in the breakdown of the material over time.
