If it doesn't have be precision use a Quickie saw with a metal blade we used them all the time to cut rebar, if precision matters get a blade for a table saw osr skill saw that will cut metal. Ive seen some use a finish wood blade turned around backwards on a skill saw
They sure will. I use them on r-panel roofing when skinning doors for dumpster enclosures. I think harbor freight sells them for about 20 or 30 dollars. I have cut panels every way you can think of. There is no comparison imo.
We always used a dull saw blade turned around backward, and use a good pair of goggles.
To be ideal I would use a plasma arc cutter to be quicker and look better.
Plasma would be the last thing I would use on metal roofing. When shears do the job, are affordable, designed for the work. That said a razor cutting wheel on a 4 1/2" grinder , works wonders when cutting more than one the same length. Stack three together and geter done!
I have a hand held electric shear from Harbor Frt. It works great of flat metal but it can't handle the bends in corrugated. The backwards blade in a circular saw is much less frustrating although not pretty.

It's not over when you lose. It's over when you quit.
Here’s a video of a guy cutting crossways through the ribs on an r-panel. Go to 8:45 mark. I’ve found that it’s easier to go through the ribs if I pull out of the cut and use the shear closer to the tip end rather than cutting at the back of the throat.
