Less than the reputation suggests — the "noisy tin roof" idea mostly comes from a specific kind of building that isn't what's going on a modern Adelaide home.
The "loud tin roof" perception mostly traces back to older sheds and outbuildings — corrugated iron sheeting with no insulation or sarking underneath, directly exposed to the underside of the roof. That's a genuinely different setup to a residential Colorbond roof installed properly.
Insulation and sarking underneath the metal sheeting are the biggest factors — they absorb and dampen the sound significantly. Roof pitch, the ceiling structure below, and how the sheeting is fixed all play a role too.
Tile is naturally quieter than metal, insulation or not — that's a genuine, physical difference in the materials. But a properly insulated modern metal roof is far closer to tile in everyday noise than the old-shed stereotype suggests, and many homeowners find it a non-issue in practice.
Ask specifically about the insulation and sarking specification when getting a quote for a metal re-roof — this is the actual lever that controls noise, not the roofing sheet itself.
Noise is just one factor among several worth comparing.
