I wonder how a vertical would perform on top of my office building? Sheet
metal roof.
20' high at center, 18' at eves. 160'X80' dimensions. I have a tripod
bolted at the center that used to be for a tv antenna. How would a
typical hf vertical perform up there?

You might want to take a portable HF receiver up there and see what the RFI
environment is like. We put a multiband vertical on the roof of a 10 story
office building and found S9 + 20 dB noise on all bands, apparently from
the HVAC controls. We gave up and took it down.
