Is there anyway to quiet a metal shed roof we will put on a screened porch? The pitch will be ~ 3/12, It isn’t a big deal but if there is some underlayment that would help I may remember you when I hit the lotto. We will collect rainwater so we do not want to use asphalt like on the rest of the house.

I would think foam board would do the trick plus you would get the insulation benefits too. Might have to go to high density like they would used under a slab or on the exterior of a foundation wall.
Thanks for the tip.

I would TEST foam as a solution before going full scale. I think a mass heavy deck would be a better solution. Instead of the standard 1/2" or 5/8", I would look at at least 3/4 - or better yet the 1 1/8" heavy T&G subfloor deck.
I'd assumed this was a corrugated metal roof, with nothing under it by defaut.
