Regarding roof replacement, J & R Enterprises can replace a metal roof with another metal roof. I checked with them 18 months ago when I thought we had finally developed a roof leak in our 1969 Hi-Lo. Turns out it wasn't the roof, just the caulk around the bathroom ceiling vent. Never considered asking them about replacing a metal roof with a rubber roof.
In most geographic areas with an urban center, RV repair businesses can be found who can replace a roof on ANY trailer. Hi-Lo roofs aren't special.
A while back, on HTF, we had a very good thread discussing the pros and cons of rubber vs. metal roofs. Would be worth the search to review. I remember there being advantages to both.
Having had a Hi-Lo with an older aluminum roof, and our current Hi-Lo with a rubber roof, my feeling is that the aluminum roof is tougher and more durable. I'll qualify that statement by saying that I kept our 1969 in the low humidity of the inland West since 1976... and I honestly don't know how long it would have held up to galvanic corrosion if it had been kept in the more humid East. After all, low humidity is the principal reason the Air Force stores all those mothballed "aluminum" airplanes at Davis-Monthan AFB in AZ. Hehe, now that my son has the 1969 Hi-Lo in the smoggy air of Riverside, CA, the roof will probably chemically dissolve in just a couple of years.
To me the rubber roof seems more fragile. Need to avoid certain types of chemicals, could be torn by a branch, supposed to clean and "treat," it periodically.... the only thing I ever did to the aluminum roof was hose the dirt off, and in a life span of 40 plus years it accumulated a number of dents and creases that never broke through. Don't think the rubber roof would have survived as well. My opinion.
