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? ...

What happens when you wash the roof? Have you tried a small amount of bleach with the wash water?
When I wash the roof the spots stay there, will try the bleach. Thanks
