We were preparing our Montana for hitting the road for three months and found issues with the roof; five extreme wrinkles running the width of the roof, two small tears and lots of spots. Dave noticed the spots last winter and thought they looked like soot but freezing temps in Iowa prevented him from cleaning. Please see link to blog where pictures are posted and anyone that can give is some direction and help would be greatly appreciated!

He also added some comments in the RV-Dreamers forum if any of you belong to that group.
Thanks for any help you can give us. We are quite concerned.
