Search the Winnebago section. There are many threads on repairing this problem.

Had this exact same thing happen on my previous 98 Chieftain. The fiberglass simply is trapped in that j channel as it makes the bend down. All that holds it in is a bead of caulk. Clean the old caulk out of the J channel. Work the roof back into the channel starting at the point where it is still in. Then just re- caulk. Go around the rest of the roof and clean out loose caulk and re-caulk before it comes out there. You'll be fine.
You are lucky the roof did not tear apart as it did on mine in a 40mph crosswind!

Here is a link to the Winnebago roof inspection procedure>>> http://www.winnebagoind.com/resource...%20Sealing.pdf You can also find the link in the Winnebago section of this forum. Look in the Winnebago Service Tips sticky. It is listed in the 2010 tips. It has an excellent cross section of the roof joint.

I just inspected my roof this year. Of the ~60’ of roof joint, only ~16’ was good. That was an eye opener.

A sharp paint scraper works well to clean the old caulk off of the fiberglass skin and the aluminum roof rail. Purdy or Wagner scrapers work well. I sharpened my scraper with a file.

My roof rail joint was pretty dirty. I used soap and water on the roof first. Then I cleaned out the old caulk with the scraper. I used the scraper to run paper towels down the joint to clean out all of the mud. I followed this up with paper towels wetted with isopropyl alcohol.

I did buy the Winnebago recommended urethane caulk. It took two tubes to do my roof.

After completing the job, I read one post where the fellow used some window screen spline shoved down into the bottom of the joint to force the fiberglass skin away from the roof rail. This allowed him to get more caulk into the joint. I may do this if/when this joint fails again.

From the looks of the third picture it looks like water got in and there is some delam under what I think is a vent of some sort.

Looks like it's directly under the vent rather than from the roof.
