I am currently renovating my hse and my architect recommended metal deck roofing. I was initially very hesitant as I am a very light sleeper and cant sleep with the slightest noise.

I checked around and this seems to be the way to go these days. Anyway, the roof has been installed. Waited for weeks for rain since it has been crazy hot.

Last week when it rained, I rushed to the house. I can say that it is about the same as roof tiles noise wise. My plaster ceiling is not done yet so what I heard is direct against the deck. But I must say this. Coz I kept raising my concerns on noise, my architect suggested an additional rock wool insulation layer which I suspect helps quite a bit.

Hope this helps you guys in deciding.

Oh ya, the other thing which made me lean towards metal deck is safety. Heard a lot of break ins through the roof where the burglars just remove the roof tiles to gain access. This one, they will need to remove the entire deck or cut a hole through the roof!
