Another company that does it, is
www.rvroof.com. They only do RV's though. I've spoke with them, and there is a good chance we'll be headed to Florida to have this done on our new SB later this year. Nothing wrong with our roof, just something I'd like to have to not worry with the constant checking, cleaning and resealing. It is pricey though. Ours sees the elements 24/7, 365, and it's our only home, so it's worth the money to me. There is a Sunseeker owner that had this done to his, at FR's expense due to his fiberglass roof cracking. He likes his.
