Sorry this is so late, we have been on the move. The roof is only about .25" thick, with solid core foam and cross bracing, not very thick at all. When I go up I either wear soft shoes or go barefoot and socks, and never go up when the roof is real cold as it will crack easier. On the other hand it is easy to repair.

Hey Jesse, I appreciate your information about the fiberglass roof repair. I had another question. How thick is that fiberglass? It always looked pretty thin to me. Thanks, Don
