I put aluminum shingles on over a cedar shingle roof, with skip sheathing below that and about 6 inches of rigid foam below that.

In all honesty, I have to say that my metal roof is not nearly as quiet as composition roofing. In a heavy large-drop rain, you can hear the individual rain drops when they hit the aluminum... Pat, pat, pat has become tink, tink, tink.

Having said that, there is no way that I'd ever go back to another composition roof.

I have thought a lot about if I had it to do over again, what I might do differently... and especially since the life of a metal roof is so long, and you don't need to worry about subsequent layers of careless nails being driven in over the roof assembly, I really wish I had put PEX under the metal roof, on the sunny faces of the roof, to capture some of the sun's heat energy. It would have been invisible, easy, cheap and safe from damage and deterioration. By now, I would have enjoyed more than 15 years of free water pre-heat... and the accompanying cooling effect in the summer.

Best,
