Shingles need to be replaced every 10-30 year depending on wear and their type. It just seems so uneconomical and such a pain.
I get that metal conducts heat more easily, but couldn’t you just let a thin layer of moss grow on your metal roof and call it a day? Even if they dry out in the summer, I doubt metal + thin layer of dirt would conduct heat more than black shingles

Not sure where you’re located, but where I am in Aus metal roofs are the norm for new builds. I imagine the climate would be a factor in the decision. Metal roofs need additional insulation, particularly in extreme climates, whereas a tile or shingle roof won’t experience as much thermal loss due to being a better insulator.
Probably other factors at play as well.
