repair rv roof

I was up at the lake winterizing our 36 foot montana camper yesterday and when I got up on the roof to sweep off the leaves, I noticed that where the front roof joined the metal there was a crack in the caulking. This is exactly the area we have talked about in the past. The EPDM rubber roof was glued down to the trailer and the metal was brought over the top and screwed down with a metal bar and then caulk was applied to seal the screws and metal bar. We have discussed before that this is a bad design. The factory could have used 6" cover tape during the original installation and I would not have had roofing problems. All I had with me was a tube of caulk, so I washed the area throughly and applied the caulk. However this is only a tempory repair. Next I am up I will install a new 6" cover strip of tape to make a perment repair. I will finially start the roof replacement on this RV camper. We will be putting a new RV rubber roof on this camper and taking pictures of it.
