Class A roofs

[MetalGator]

I currently have a TT with a rubber roof. Do Class A motor homes also use rubber roofs?

I have had both rubber on a gasoline coach and fiberglass on the diesel pusher. I prefer the fiberglass. When you walk on the roof, it is solid. But like anything it does require maintenance. You have to wax it to prevent UV rays from eating it up. Just like a paint job on a car. If you wax it with a good UV protection type wax, it will last you a long time.

I have a 1993 HR Navigator with a rubber roof, and it has never leaked or had a problem. The Navigator is the top of the line coach from a very large RV manufacturer who also uses aluminum on some of its products. Our 1989 HR Imperial had an aluminum roof that also never leaked or had a problem.

So, having a rubber roof doesn't mean the rig is cheap or the roof will leak. Having said that, I did have it coated with a non-petroleum based paint in 2003 to help preserve the roof. RV manufacturers do not recommend coating the roof with anything but just keeping it clean using a soft brush and mild soap.

Just like everything man made there is cheap fiberglass and good. That applies to rubber roofs as well. Some maker using fiberglass had a problem with them lifting at the edges a couple years ago.

Some do, Some don't You can get Rubber (Several types) Fiberglass and aluminum depending on the make and model. Mine is Bright Tec, One of the Rubber roofs. I like it. I can walk on it, I'm 300 pounds shower weight.

And some use molded fiberglass and aluminum. All are different depending on the manufacturer.

Depends on the coach. Some have TPO, some have fiberglass, some aluminum. I think you'll find most of your entry level coaches have TPO, spend more money and get fiberglass. There are a few exceptions, I think Winnie and Tiffin spec fiberglass even on entry level units. That said TPO is a good material and with the right care will last a LONG time. TPO is the cheapest to repair but also the easiest to damage. Fiberglass obviously lasts much longer with less care as well as aluminum.

Yes. Some use EPDM rubber,some TPO thermoplastic material, and some use fiber glass cloth impregnated with polyester resin.
