You can purchase copper flashing rolls from hardware stores pretty inexpensively. Attaching that to the roof will work, but you'll need something strong enough to hold it in place. Drilling through/into the roof in enough places to do this is going to be problematic.

Depending on what frequencies you run, it can be pretty easy. Some of the larger antenna manufacturers produce pre-made/pre-drilled metal disks, but they are around 6", so really only good for UHF and higher frequencies. You could certainly make a VHF version.

Go find someone who does commercial AC duct work (with the round stuff). They generally have 18”-20” blanks laying around. Last time I acquired some, they were 18 ga with center punches in place. Got 20 of them for $5. Made good targets as well as ground planes…
