Do you have pics of the hail damage?

The problem with hail damage is that (at some point) it becomes more than just cosmetic. Whenever the contour of the roof is compromised, the aluminum can come delaminated from the polyester foam core. The lamination of the aluminum on both sides of the foam core is what creates the strength of the structure. It's normally not a critical issue but it does weaken the roof incrementally.

If the dents are small, you can cover the roof with a filler, then sand it smooth (it's called "Fairing") and paint it. That won't restore the strength but it will restore the cosmetic value.

I replaced and faired the entire fiberglass deck on my 45' yacht. I completed the job in 5 days. I think that one could fair out a TM roof in 3 days.
