The venue in which I most recently resided had a metal roof.  During the 
heaviest of rains we could hear it, but we had to listen for it.

  As I recall,  there was the metal roof, then a 2" layer of sprayed-in 
polyurethane foam, then intumescent [but flexible, not sure if rubberized 
or not] paint, then 3-4" of fiberglass insulation. Now, the jet engines 
from the airshow didn't seem to give a whit for all that, but take that for 
what you will.

  So, it can be done.
