Rubber or aluminum roof

I have had them all, it would seem an all fiberglass roof or aluminum is best. Currently all aluminum on a camplite.

All the comments are interesting. I have no idea what kind they are, but in heavy cross winds, and usually a 5ver, the roof is pulling away from the rig. Always going in the opposite direction so warning them is tough.Looks like a big balloon.

I suspect not a good day for them.

my 96 coachman has a 1 piece aluminum roof. Yes..it is dented from whatever treatment the previous owners did..but no leaks.

I recently bought a 2014 Forest River Work and Play toy hauler. It has a single sheet aluminum roof, like a cargo trailer. The problem with an aluminum roof is that it absorbs heat much more than rubber over wood construction of most trailers nowadays. I understand a common modification is to paint the roof with white "snow-roof" paint to reflect the sun's heat, and making it easier for the air conditioner to cool down the inside.

trailmanor uses Al-foam-Al for its roof and walls.
foam is about one inch thick.
very strong, you can kneel on it.
But does dimple with hail, and scrapes.

I have a rig with an aluminum roof, it is 42 yrs. old and not leaking.
Ideally, a single sheet of vinyl coated aluminum would last a long time.

The thing about rubber is that it is so thin, it can get a hole punched through it very easily. Combine that with the fact that the seals are at corners that get wind (which is almost like a pressure washer action), and it is no wonder why it is only a matter of time until a RV with a rubber roof self-destructs.

My ideal roof would be one piece aluminum that is "cupped" around the edges and corners, so water getting in past a seal on the sides of the rig doesn't mean an instant leak, unlike rubber roofs. Then the items on the roof are installed (A/C flange, skylights, vents, etc. Finally, the entire roof is then masked and sprayed with an epoxy based elastomer sealant (rvroof.com, Rhino Linings.) The result would be a one piece roof with no need to worry about caulk or Eternabond, and even if scratched by a tree branch, the roof likely will still be watertight unless the branch punctures the metal or knocks a vent off.

I concur. My unit is 21 years old with a one piece aluminum roof. It had the original seal and one "redo" job with liquid sealant .... the type that dries hard and cracks.

I just finished scraping, sanding down as much as I could of the old stuff, washed everything down with "9 Lives" commercial cleaner, prepped it all with isopropyl alcohol and then used 3M's Extreme Sealing Tape. (3" width, 2 mil thick). It works awesome.

Aluminum pitting can happen even in open areas where dirt is not trapped ... sometimes it's just the wind action and the road dust/fine debris that acts as a comstant sandblaster on your roof.

Best solution is always maintenance. Wash your roof with a good cleaner at the beginning, middle and end of your season. That should be enough to avoid most major surprises and costly repairs. ~ Bugjr ~

One piece aluminum roof some eternabond tape on all seems and vents and no worry. My unit is 24 yes old and no leaks. Only thing I check is the AC gasket a few times a season.

my previous tt was 29 years old when I sold and the aluminum roof was still in great shape. other than caulking vents every few years and parking it outside for four seasons I believe an aluminum roof will outlast any rubber roof

I used 1 piece fiberglass I wouldn't use Rubber on a doghouse rubber is used because its cheap and can be run around the corner stapled down and trimmed. It tears easily (tree branches) has to be treated regularly.
