The 4' would be no big deal, the 20'+ height would though.

Well, the 7/12 pitch on a metal roof plays a factor as well. With the eave overhang, the physical gap was probably only 3' 6", but I dare anyone to shimmy down to the very edge just to step across.
The worst part when you're on those things and you're thinking, "I hope this metal is in good shape, at least it's full of corn." Then when you get to the top you see that it's completely empty.

You need to film w/ a GoPro and a fake Russian accent next time.

I wore a Go-Pro on a roof once, and even though it was a partially wet wood shake and I actually slipped, it was pretty boring.
