To vent or not to vent? To insulate outboard or inboard? To provide details or just let contractors wing it? These are some of the questions two pros, who spend a good portion of their work days crawling around on roofs (of both wood framed and masonry buildings), will address. They will share case studies of roof failures; go over edge and penetration details that are so critical for long-term durability; discuss how to take advantage of opportunities to improve thermal performance; and share some of the latest geeky research, including how to do an unvented assembly without code-mandated spray foam. You’ll leave this session knowing what works, what doesn't, and how to juggle budgetary, design or building constraints to build durable, low-risk roofs.
