which roof is better?

Was recently posting on the TC blog about switching out of my fiver to a TC, but with the help of those on that blog, I decided that a more fitting camper for me would be a TT. Now, just curious, is there a consensus regarding what type of roof is better and more resistant to UV and leaks, i.e. fiberglass, rubber, aluminum? The fact is that my next camper, just like my present one, will never be covered so I'm looking to see what peeps think will be the best able to handle the elements under my circumstances?

I'm new to Rving and I have a 21 ft. TT. It has a rubber roof. I think it's stupid and just waiting to fail.

But, for some reason....the majority of RVs have them. ???

I think you will find that there are practically nothing but TTs with rubber roofs available. Fiberglass would be more durable, you just gonna have a hard time finding fiberglass on anything but MH roof.

Airstreams and the "eggs" like Casita are the only none membrane roofs I can think of.

The industry makes 300,000 TT and Fiver "rubber" roofs a year. How many do you think leak?

Not the case at all, quite a few travel trailers have been and still are manufactured with a TPO roof which is vinyl, not EPDM rubber, my own previous KZ Spree being just one example. Personally I'd much prefer to have a TPO roof on my current Freedom Express but Coachmen like the majority of other manufacturers chose to use crappy EPDM which chalks by it's very nature, is difficult to lay down flat and keep it that way throughout it's life, and will tear if you even look at it sideways. :( Regardless, any roof will leak eventually if it's not properly maintained.

lots of small TTs with fiberglass roofs. I wouldn't have another rubber one myself.

One too many...

The EPDM membrane is not that bad of a material. Where RV roofs leak is usually around through holes or at roof edges, not through a deteriorated membrane.

I have an aluminum roof that is coated. I think it's durable. There will probably be few being built with aluminum because of cost.

The newer Line-X type sprays have a lot of promise with some installers offering a lifetime warranty.

I was getting ready to make this exact same statement Bumpy, but you beat me to it.

I had a EPDM roof that was properly maintained, not damaged, caulked frequently, etc. and at 5 years service the membrane started failing. Moisture was leaking through the membrane. This is obviously an expensive issue and the 12 year rubber roof warranty that all manufacturers advertise is totally worthless. Try to make a claim and see how far that gets you.

I had my rubber roof replaced with RV Flex Armor (rvroof.com). I will never ever have another rubber roof other than the length of time it takes to take delivery and take it to a rvroof.com install facility.

And now I can even hear the television when it is raining due to the thickness of the RV Flex Armor material.

A misstatement of fact. The 12 yr roof warranty is on the membrane itself, not the trailer roof, and is not offered by "all manufacturers" but rather by the membrane manufacturer which in the majority of cases will be Alpha Systems. If your rubber roof membrane was thinning to the point where it was leaking before the 12 yr mark any claim would have had to have been made to the manufacturer of the membrane.

edatlanta - that will be our next big purchase, an RV Flex Armor roof. It will be worth it to us as we plan on keeping our 5W.
