.... ok if you say so.

Yep. Made it myself.

I believe you described this edifice as a "shed", by which I assume
you mean as in "shed to store a lawn mower" rather than "shed to store
the Hindenberg". What are the actual dimensions? It makes a
difference in how much load everything has to support. And how much
if any snow do you usually get? That also makes a difference.

Can get by w/ 2x4 OC for roof-ceiling assembly or attic assembly only.
If attic, can only be 32-ft span.

Any more would need 16 OC to meet code.
