Many years ago when I lived in Australia some houses had "tin" roofs.
Apparently when it rained the noise was awful.

Made up for, no doubt, by the fact it was raining.

The tin has several inches of insulation under it. The major problem is
preserving the weather seal at joints. Tin flexes in violent winds and
expands and contracts a lot more than stone or clay. Large sheets being
both a blessing and a downfall. I imagine going around the finished
product with a soldering iron might be the only way to cure that.

Wouldn't the solder tend to come away from the steel when flexing occurred
on hot sunny days?

Not when the roof is designed properly so the metal can move.

If the metal moves, the solder is put under strain.
