Darn I thought I fixed my leak

[wvabeer]

I have removed, replaced skylight both fans and sealed every thing that goes thru the roof as in all that I have posted here. In three corners of my roof it has leaked. When I apply Dicore self leveling caulk it works till I drive it. I believe the flexing is causing the cracks to open back up. That is why I am going this route possibly because the rivets are a little loose. Mike at the service department with Airstream told me this is the correct route to take. I was concerned about whether the aluminum sides would lift up high enough to get under to clean but he said it would lift up high enough. I will take pictures and post them.

Here are pics of the job
If you notice there is not much roofing under the side lip and most of the rivets looked good from the surface but after a little prying they came up and they were rusty.

WvaBeer, was wondering if your last efforts were successful? From your pictures it was surprising that the fiberglass didn't go under the metal caps farther. No wonder these roofs have such a problem leaking. So the spots where you replaced the rivets, were rivets to begin with? On mine there is such a big dab of caulk I assumed it was a large screw or hex bolt underneath. How long did it take you to finish the job?

It took me about 8 hours. I believe the guy at Airstream that put this motor home together did not care about quality. I have repaired so many things that if it were done right when it was built, it wouldn't have needed done. About 3/4 of the rivets were rusted down deep so that you couldn't tell they were loose untill you pried up on them. Just replacing all the rivets would be a very easy job. They are 1/4 inch and require a large rivet gun 20 bucks from harbor freight.

YEE HAW!!!!!!! No leaks I drove it on some rough a$$ roads drove home we had wet snow on the roof melting all day and NO LEAKS

Well I think the same guys were still working there in 93 when mine was built, cause I've had the same issues with quality.

Replacing the rivets was the first thing I did on my 92 LY. After that it didn't take much to seal the remaining surface.

Two years now and not a single leak since.

As you can see from the pics there was too much rust under the metal edge to seal on mine. As Gloran said there wasn't much overlap on the edges, you would think there would be at least a complete hole thru the fiberglass to seal around.
