Need guidance on best roof trailers

Most all RVs have rubber roofs and are sealed around the edges and the penetration points like vents, etc. How well the trailer was maintained has more of an effect on leak resistance than a particular brand. I would think if you are doing a seasonal site especially in upstate NY you would want to build something like this:

Roof maintenance is the key. Check those records closely on a used RV and do maintenance at least twice a year.

The longest lasting roofing material is aluminum. Still not perfect as there will be seams that are potential leak points.

Any trailer that is 10 years old and not had EXCELLENT care (wash and treat with UV resistant spray) is going to need a new roof (NOT A RECOAT) soon.

A carport type covering is your best solution.

We have a TT with a fiberglas roof, made the same way as the walls. It is a 2014 and shows no signs of deterioration.
PS it is a Evergreen Ascend 231RKB, which is regretfully no longer made.

Molded fiberglass is right up there, too.

Most of the GMC motorhomes built in the 1970's still have their original roofs. A lot of them still look brand-new.

I forgot about that because there are so few RVs that have that.

TPO, especially commercial grade (thickness) is an excellent choice for an OEM roof.

For the last 8-10 years the vast majority of travel trailers and 5th wheels have Alpha Systems Superflex roofing, basically a thin PVC, think thin pool Liner. Forest River and Thor use it on most if not all of their brands and it has been on every Grand Design product ever made. That's about 90%+ of the towable market. Alpha systems entered into an exclusive distribution agreement with Lippert in 2020, that should tell you its the cheapest material available.

What is TPO?

What brands use aluminum roofs?
Thanks.

I don't know anyone who keeps records of every time they work on their roof, change the oil on their gen, winterize, or any of the other stuff that people do all the time. I doubt legitimate records exist for most used RVs unless the previous owner took their RV to a service center for all of their routine maintenance.
