Roof venting for an insulated workshop
I am working on designing an insulated workshop in northern Ohio, and I would like to work out the details. I want to insulate the inside of the roof to use the available storage space. Can I use any type of insulation on the inside? Would I be able to install a metal roof on top of a cross pattern as shown in my attached picture? I was thinking to use a ridge vent. Is venting on top of the sheathing any different than installing foam board underneath the sheathing with an air gap?
Any advice about what you see in the design would be appreciated.
