Hi folks! I purchased a 1998 Holiday Rambler Alumalite from a friend. Upon close inspection (he has no real rv knowledge) I’ve realized the roof is half aluminum, half rubber in 4 sections, taped up with eternabond tape. The caulk is faulty all over and in need of replacement, and the shower skylight has been leaking due to excessive pooling on the aluminum side where it’s caved in. I’m guessing there have been other leaks too that have damaged the roof deck…so my question! I want to just replace the roof, no more patches. Replace all of the roof decking that needs it, replace damaged skylights and fans that have stopped working. What challenges would I face in taking ALL aluminum off and replacing it with a rubber DIY system? Any advice?
