Carbide, but you don't say for what tool..
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style.

On a skil saw some just place blade on backwards and use it that way.

It’s been my experience that circular saws, sawzalls, or side grinders suck for cutting metal roofing. Metal chips or sparks will eat you up.
Get a hand shear, you’ll be glad you did. That’s what they are designed for and it works great.

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

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.

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.

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.

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.
YMMV

I'll add a good set of ear muffs too.
This method is annoyingly LOUD.
