Should I vent enclosed soffits on a house with an unvented cathedral ceiling?
We're in zone 4C at 1550 feet. Building a log house. We're planning on an unvented cathedral ceiling (2 in. closed cell spray foam with balance of rafter bay filled with additional insulation). The roof (12/12 pitch) is shingled at this point in time. We utilized I beam style rafters. We wanted to use cedar T&G planks on the underside of the soffits (4 - 5 feet wide). We hope to have a few recessed can lights in the gable soffits. Should we vent the soffits? If so, how? Or is the T&G "leaky" enough for ventilation. It's rather wet here, 30's to 20's for periods during the winter, 70's with sun during summer. Concerned about moisture in enclosed soffitsLeaving soffits open won't work. Can't find recommendations for this issue! Thanks.
