Rubber vs Solid Roof

the roof on our tt is a solid fibreglass material, previous tt was a rubber material

pros and cons?

    Neither does a rubber roof.

    OP, a fiberglass roof would be a considerable upgrade in my mind. Less likely to tear and they don't naturally chalk off like a rubber roof. Fiberglass is easy to "fix", but its hard to make the fix look pretty. I had an old fiberglass Jon boat with a crack in it. Bought a $10 repair kit and fixed it myself in a day. It still floated when I sold it a couple years later.

    A big downside I could see is weight. Fiberglass is thicker and heavier than a rubber membrane. I don't see it working on lightweight models where every pound is a tradeoff, but if you have enough truck it sounds like a great option!
  • the roof is in great shape, I was surprised when we bought the tt by the solid roof
    its a gulfstream x22fb btw, 2002 year
    really light for its size, 3000 lb dry according to the manufacturer
  • I would take fiberglass. A few weeks ago I discovered a weird tear in one corner that looks like a critter was gnawing at it (we park it under a tree). That wouldn't have happened with fiberglass.
  • I would take fiberglass in a heartbeat.

    Since it's on the roof, you don't need a pretty repair, so some epoxy and fiberglass cloth and its' easy to repair if you do get a puncture or crack.\

    Yes, the joints around fixtures still need to be kept sealed.

    Not at all, any competent boat shop can fix a fiberglass roof. Heck, as a DIYr I can fix a fiberglass crack or hole without much trouble, only a major structural compromise would be difficult but that would be hard regardless of composition.
  • Pros, it won't deteriorate like rubber and it will stand up to scrapes and possible punctures. It doesn't need a conditioner. It still needs all the holes and joints re-sealed every 3-5 years. I don't see a con to fiberglass myself.
