Black spots on rubber roof ???
We have an 09 Bighorn, small black spots on entire roof and slideouts. 5er sits outside, no birds or trees around. I have regularly washed it a few times a year. What causes this and how do I fix it? ...

These are mold spots. They do not harm the roof. Just not very attractive. My fiver has them too.
