Build Science™ 401 concludes with Episode 12 where Matt Risinger and Steve Baczek review flat roof design, insulation strategies, vapor profiles, and the importance of coordinated detailing between trades to ensure durability and performance. They cover details of a flat roof, including slope, insulation, membrane protection, drip edges, lack of parapets, and roof overhangs, with practical reasoning for each design choice. They also cover water management strategies, including gutters and a subsurface drainage system, and considerations for materials like plywood versus OSB on flat roofs. Matt and Steve stress understanding building-specific conditions, using data-driven design decisions, and avoiding unnecessary or ineffective features like venting flat roofs.
