Unvented cathedral ceiling
Hi everybody, at the cottage I have to replace the actual roof shingles and try to correct a problem with ice-dam, I want to install rigid Styrofoam board (1.25 inch) directly on the sheating then strapping over it and new sheet metal roofing. I wont be using a ridge vent since i'd like to make it unvented, also i'd like to leave the ceiling untouched if possible, right now the rafters are 2x8 there is only 3 inches of fiberglass bat in there whitout any vapor barrier. The pitch is a 3 to 12. So i'm wondering if I can do it by the roof only. About the actual soffits; should I seal them or let them as is ? Thanks for any advice.
