Sealing the roof seam on a Jayco

[hoseppy]

Ok, figured out the mildew thing.  Very mild bleach, Woolite & Scotch Guard as OM recommends.  I have a small leak in the center seam across the roof.  By the looks of the unit, a '98, it hasn't had alot maintenance - not alot of use either, so I guess that kinda balances out.  How would I go about sealing the seam?  Here's my guess.  Remove the vinyl strip, remove screws holding the metal seam cover, clean out old caulk, re-caulk, replace metal seam cover and vinyl.  Does this sound right? And if it is, is this what needs to be done to the side seams as well?  
Thanks guys,

I am more or less copying and pasting a post in a similar questioned thread. I removed a bunch of screws and stuff from our roof when I recaulked it.

Although I did not rebuild my roof, I did overhaul its caulking, which was quite a job. I carefully took off all the old caulking (and some other pieces). My local camper dealer recommended a special kind of construction caulk (which they stocked, of course). I don't remember its specific name, but it wasn't water soluble. Had to use kerosene (or some other non-polar solvent) as its solvent to clean. Has worked very well, because before I did it, we had a bad leak that I couldn't pinpoint, and now, no more leak!

There are patch kits available for canvas and vinyl, but I'm not sure how good they are. I would imagine they would at least help keep the tear from getting larger.
