Just what I've seen, unless one caulks a roof often (all it takes is a small crack or gap for a water leak), or uses something more permanent like Eternabond, eventually the roof will get a leak somewhere, likely imperceptible. This doesn't mean that fiberglass roofs are 100% leakproof, but they have far fewer seams to worry about.
The crazy thing: Two rigs with identical floor plans (Sunseeker 22SLEF and a Thor Freedom Elite 22FE), chassis (both E-450s), and amenities, the difference in price that they sell for at local dealerships is over $30,000. The biggest difference? The Sunseeker has a fiberglass roof. So, for that big a price difference, I'm sure there is some way I can make a TPO roof be able to keep from leaking for the long haul.
