I see plenty of copper roofs but I' can't say I've ever seen a aluminum roof installed.
50 years ago aluminum was pretty common as a shed roof in the midwest. At that time the only steel alternative was galvanized and it was less than perfect because of corrosion at fasteners and cuts. The aluminum used was very thin (because of the high cost of aluminum at that time) and it sometimes had problems with wear at the fasteners and wind failures. When the modern steel paint treatments became available the aluminum kind of disappeared. It's just all cost and performance and it changes with the technology.
Speculation on cost of repair is interesting, but for me, like most people, it really wouldn't make a difference unless someone can show a significant difference in insurance cost. I don't pay for repairs, I only pay the deductible.
