Went back out to take a look at things.. cut a small piece of aluminum and tried to work it up under the roof skin and that isn't going to happen.
The only way I can do it is if I cut the adhesive used all along the edge of the roof skin on that seam. I think that will do more harm then good so here is plan "B"...
The roof skin is secure but the wall skin is not. The wall skin was originally held tight by the gutter and the gutter sealant. I'm going to drill and rivet the wall skin to the main frame all along that seam ever 6-8" so it pulls up nice and tight. Any loose areas along the roof skin seam will get the same treatment. Then run a nice heavy bead of "Through the ROOF" along the seam and fill the gap...
Through the Roof!® by Sashco - Roofing Sealant & Caulk
After a week or 2 of cure time, I'll reinstall the gutter (slightly trimmed on the ends to allow for better drainage) using butyl tape and screws through the original holes. The gutter will completely cover the seam/gap as it did from the factory and the butyl tape should add another layer of protection from leaks.
That's about the only semi-permanent/permanent fix I can think of without damaging or removing parts of the exterior skin which I have no intention of doing.
Thanks for the input guys
