Cutting Metal Roofing
What is the tool of choice for cutting metal roofing panels? Lots of cuts due to incorrect length.

I ended up using abrasive blades, but the cut was poor, noisy, and a pain. I had purchased a special "expensive" metal cutting blade, looked like an 80 tooth carbide, but it through fragments like a grenade and only lasted a few cuts.
I have since used several diamond blades on concrete and I'm very impressed. I googled same and found only "Rescue" blades, which are expensive, but sound like they would be perfect. Here is one link, but there were others.

Whatever you cut it with, keep all particles away from the good surfaces as they will start to rust.

Tried the jig saw with a metal cutting blade, too slow. Also bought a power nibbler, but it had trouble handling the ups and downs of the style roofing I was using. Mine was basically the same as the big box stuff, I just had it cut to length. Fortunately only a few cuts to make, 5,000 sq ft. but it sure went fast.
The auto shop I spend time in uses a sawsall with an inch wide blade for exhaust work and such, maybe worth a try.

WP...are the cuts all going to be the same? Like cutting a 12' to 11' 6"?
How about taking them to a sheet metal shop?

Well, I'd probably stack them all up, or as many as will cut easily, make a simple clamp out of 2 x 4's and some bolts. Then just use a sawsall and cut 'em all at once. Could just touch up paint the cut ends while still in the clamp.

Speaking of stacking them up. We pre-drilled ours and it made it a whole lot easier. Uniform placement and real easy to run all over the roof and pop the screws in. Just be careful drilling them as the slightest shift and it turned into a drill breaker. Broke half a dozen bits and if you stack too many you can get off center.
But I agree with GG that stacking and cutting would be easier.
