Unvented roof questions
The last few feet (closest to the house) of the roof for the room over the garage basically ends on a side wall for the second story (there is also what I believe is called a cricket). Please see the attached roof plan, I’ve circled the area in red. Please also see the attached pictures from the inside. My plan was to do a vented roof. The sloped portions of the roof between the kneewall and attic area are to get baffles followed by closed cell spray foam followed by high density fiberglass batts followed by drywall in order to get the required ceiling R value on the slopes. The last three rafter bays have no soffit, so no way to draw in air from the non existant soffit. Is it possible for me to create an unvented roof assembly on just those three rafter bays up to the attic level utilizing closed cell spray foam?
