I loved the aluminum roof on my 37' motor-home. Never had to do anything to it. Reflected heat a lot better than a rubber roof too. I wish I had an aluminum roof on my present 5th wheel. I wouldn't have had to re-coat it this last spring.

Lazy Daze is probably the only Class C with a metal roof.

Be aware, too, that there are multiple types of membranes that at first glance might seem to be rubber roofs. Besides actual rubber, one can have a TPO roof (which is longer lasting than rubber) or one or two other more proprietary membranes. The differences may be important when making repairs or getting appropriate sealants, as not all such materials are recommended for all flexible roof types.

No matter what type of roof you have there is the same number of cut outs for vents, AC's, skylights etc, this is where leaks occur. I have a 24 year out MH with a rubber roof(EPDM) it has never leaked through the membrane. I recaulk and inspect at least once a year and never had a roof leak. I have resealed most of my windows due to water leaks because butyl rubber tape dries out. I have seen MH's with FG roofs with a lot of water damage because caulking cracked and water got in. So I would be more concerned how the roof was maintained rather than the material the roof was made of.

What ever kind of roof you get, maintenance is the most important. In a class C, look very carefully at the cab over, that is a common place for problems with a class C. Good luck with what ever you buy, just have fun!

Both of the motorhomes in my signature have metal roofs. Had rubber roofs in previous motorhomes and much prefer having metal roofs for ease of maintenance.

The 1st thing I did when I purchased each one was to apply 4" wide Eternabond tape around the entire perimeter of the roof seams where the roof meets the sides and seams on the front and rear caps. I also apply Eternabond tape around all roof vents, skylights, antennae mounts, ladder, etc. Been using Eternabond on 8 different motorhomes for 20 years and never had a leak after applying this tape.
