Is a metal roof louder than asphalt in rain?

Modern metal roofs over a solid deck with synthetic underlayment are roughly the same dB level inside the house as asphalt during rain — measurably loud only on porches without a finished ceiling. The old comparison (metal = loud) comes from agricultural barns where corrugated metal sits on open purlins with no underlayment or attic insulation.

Trill installs metal over standard decking with a high-density acoustic underlayment specifically for the noise concern. After install we’ve never had a homeowner mention rain noise. Hail does sound different on metal (a sharper tick versus a thud on shingles), but the dB level isn’t higher. If interior noise is your only hesitation, it’s not a real one.
