Venting Soffit / Overhang
I'm presently building a house with a flat TJI roof. Over the living space there is sloped foam that provides the R-value for the roof as well as the slope. Above the overhang is simply 5/8" T&G followed by torch on. Above the exterior wall separating the overhang space from the "attic" space is blocking sealed with DOW XPS and spray foam. The underside of the overhang will be stained T&G Pine.
My question is, does the overhang cavity need to be / should it be (or not be) vented?
Thank you for your help!
