We are going to build a cabin in northern WI, for ourselves . My initial thought is 26' wide. 13'span with a supporting wall down the middle. A shallow pitch (3 or 4 :12) shed roof on ICF walls. I am wondering what span can be achieved with a osb roof SIP. Also the limitations for self-supporting eves. Or how to do a very large eve. Do you have some design tables for that application? The snow load minimum is 40psf, although I would like to be ready for more. Dead load for the metal roofing is minimal.
