I am so confused. 10x20 shed I'm finishing out for a home office. There will be no water or plumbing in it just office space. In NC so seldom snow. For the roof since it has a storage loft there will be no atticno unless you count that little triangle space where the flat section of the ceiling will cover. But the roof vents are below that. And since I am sealing up every little crack and insulating should I cover those vents? I had planned to use rolled insulation between the rafters. I've seen where some people use baffles but then the rafters are too shallow for the roll. I really don't want to have to go and install extension pieces on every rafter. There is a ridge vent. That's covered with some kind of black paper. Will that have air flow? Do I need to punch holes in it? Sorry for the stupid questions but I just don't know. The roof itself is metal.
