Contrary to popular belief, when installed over solid decking a metal roof is not noisy when it rains. In fact, according to one study, a metal roof’s noise levels are about the same as other products like asphalt shingles, wood shakes, or clay tiles. The idea that metal roofing is noisy most likely comes from installations over open framing. An open framed installation does increase the noise a metal roof creates.
