You can cut metal roofing and siding with a wood blade. It is easy.

It is easy to cut metal siding and roofing with a wood blade. I have done it many times by simply reversing and old wood blade on your circular saw. In this video I cut through 4 sheets at one time using my skilsaw. I was cutting this metal for use on my spring hill campground I am developing. ‪@FlanaganHomestead‬
