I'm wondering how practical a metal roof would be for my garage, which
is WAY past due for a reroof. it's virtually completely flat, 20 x 30
feet. I think there's a slight rake because there's a gutter along one
30 foot side. Normally, a flat roof would mean hot tar, virtually
impossible DIY and probably only good for 7 years. I figure a metal roof
properly/adequately installed might last a LOT longer, possibly with
occasional upkeep of some kind. Can anyone on this?

When I did the metal roof over my place the pitch was 2 1/2 in twelve. Not
so great in snow country. I added structural members to change the pitch to
5 in 12.
