How to Cut Corrugated Metal Roofing?

Eduardo blew some of the 2' x 12' galvanized, corrugated steel roofing
material off of my barn, and I had to replace most of 2 sheets.

I didn't have any power on Saturday to cut it off, so I just nailed it
up and let it run long off the eave of the roof, but now I have to cut
it off flush with the rest of the roof.

Can anyone tell me what I should use to cut this stuff?

My brother (a contractor) says I should just put a plywood blade into
my circular saw backwards, wear safety goggles and earplugs, grit my
teeth and let 'er rip ... but somehow that sounds a little scary to me
on an 18' ladder.
....

What gauge material? If it's anything heavier than 26, for just a few
sheets I'd go w/ the Sawzall metal blade if it's in place already.
I've heard of the other "trick" but no experience w/ trying it. I
might try one on the ground to see what works. Any way to stay on the
roof and work from the top instead of off the ladder?

BTW, I thought Ed only had 50-ish mph winds by the time it got there or
was there a local spawned t-storm? Or is this an open barn that the
wind can get under the roof? Seemed like shouldn't have lost much for
what I heard of the storm so wonder if was adequately fastened down
initially...just a thought/consideration from far away.

Because it's corrogated, there's no easy way to keep the sawsall
grounded against the metal while cutting, which means that its
going to be really hard to control the beast against it's
reciprocating motion. A light circular saw may be
easier to control in this application.
