i have used a blade like this for sheet metal and for cutting 2" angle iron, worked great.
definently safety glasses, long pants. i am not a big fan on drills, circular saws, lathes or belt sanders while wearing gloves.
i have done the backwards plywood blade, works good on aluminum with lots of wd-40, on steel it was a mess, maybe i did it wrong?
Install your skill saw blade on backwards and have at it, watch for hot metal..
since you are only cutting a few sheets, i would recomend this. if you ever cut more than that though i would recomend a metal cutting blade for your skil saw, they cut way cleaner than the regular wood cutting blade turned backwards. another tip is stack all your sheets together once they are cut, and drill holes through all the sheets where your screws will be, that way you dont have to put more effort into screwing through the metal when your standing on the roof (you will love this if the roof is steep). btw i have done quite a few steel roofs so let me know if you have any more questions

Use a cordless 18v saw with the smaller blades and simply toss the blade when done, metal cutting blades just wear right out after a few cuts. I used a royobi 18v and it works great with a plywood blade on it.
