Lean to
I am adding on to my pole barn. A lean to that is 10x24 Because of the pitch, I need to use a metal roof. So my question is, can I use 2x6 for the rafters spaced 4 feet apart and use 2x4 for perlins spaced 2 feet apart?

24 foot long and 10 foot long rafters. Live in Ohio where we do get snow. Just using pine framing lumber. The pitch is what I have an issue with. it will be a slight pitch. Maybe a 4inch raise total over the 10 foot span. Maybe a little more but not 12 inches

I'd suggest you do 2x8 ledger, 2x8 rafters on minimum 32" centers. I'd put purlins on 32" center too. And you will want a 2x12 beam under them in front if you only want to have 3 posts.
