I'm sorry, but I must be missing something. Seriously, why would anyone want a rubber roof or an elastomeric roof instead of fiberglass? And why would you put one over a perfectly good fiberglass roof? IMHO, Fiberglass is vastly superior to rubber on a roof. Fiberglass is flexible, it doesn't tear or peel up at the edges and it's nice and slick so those leaves and pine needles slide right off at about 45 miles per hour.
I have no actual experience with this other than living on fiberglass boats for many years; however, I would think the best way to revive a fiberglass roof would be to sand it lightly, acetone any wax away, and then apply a two-part epoxy paint like Imron or Algrip. The stuff is like granite once it kicks and dries and you still have all of the properties of the original slick and shiny fiberglass roof. If you didn't want to fool with epoxy, do it in white gelcoat.
I could be wrong about this. It wouldn't be the first time. I'd love to hear some good rebuttal.

If you use the search feature of the forum and type in "roof", you will see a number of posts that involved that word. If you check out the ones that are in the RV Maintenance and Technical Tips area you will see at least two threads regarding this. Those answers may be helpful to you.

I have had a fiberglas roof for 2.5 years and won't get another. My roof is 2 pieces screwed together and the constant flexing of the trailer pulls the seam apart. The fiberglas in mine has developed cracks and it has been back to the fiberglas manufacturer twice (Jun 08 and Sep 09) to have the cracks filled. To be fair, I think the underlying support for the fiberglas is insufficient (it sinks if you walk on it...which I try not to do) and perhaps that's why it cracks. If it were one piece (not two) and not allowed to flex, I might like it but with what I have, its not great. This is one guy's opinion that owns one.

We own a fiberglass roof and the same unit as yours is. You need to take it back to your dealer and let him deal with it if you still have a warranty. We have no problems with ours use dicore. Also you should ck your RV roof from time to time for any problems.... Rv's are supposed to flex if they dont they have problems. southwestjudy
