cut through metal roof
I need to cut a 16" diameter round hole though a metal roof. The standard R-panel type metal roof panel is installed onto 5/8" plywood, so I need to cut through both the metal roof material as well as the plywood both at the same time; removing the panel and cutting it separately from the plywood is not an option. I have a reciprocating saw so which type of blade would I probably use for this? The "bi-metal" and if so how many teeth per inch? Or should I perhaps use an angle grinder with a cutting wheel to try to cut through the metal first, the cut out the wood with the reciprocating saw afterward? The round hole does not have to have a perfect smooth edge, just needs to be round so I can slip a 16" pipe through it and will be dealing with flashing afterwards, of which I'm not asking about now but am just asking how best to cut the hole, what blade/method? thanks

Please consider eye and ear protection for your project. On an overhead project the last thing you need is flying debris to cause a distraction that compromises safety!
Good luck with your project!

I would use the saws all with a fine metal blade, it will cut the wood!
