07 - ROOF DRAINAGE SYSTEMS

Send us Fan MailProper water management is critical for roof longevity and foundation protection - that's the focus of this episode. We explore gutter systems in depth, explaining why they're considered essential despite not being required by building codes in most areas. Learn about common gutter styles (half-round and K-style), materials (aluminum, galvanized steel, copper, vinyl), and proper sizing for different roof areas. Discover the importance of proper slope (1/16 inch per foot), secure attachment methods, and why downspouts must discharge at least 5 feet from foundations. We discuss integrated gutters (Yankee Gutters) and proper splash block or downspout extension installation. For low slope roofs, we examine three drainage methods: over-the-edge drainage, scuppers (rectangular openings in parapet walls), and internal drain pipes. Learn why secondary drainage systems are required and how to identify common problems like blockages, deteriorated components, and ponding water. This episode emphasizes that proper drainage prevents basement flooding, foundation damage, and provides crucial protection against wood-destroying organisms. Essential information for maintaining any roofing system.Intro This episode is brought to you by GetSync.pro This episode is hosted by Charlie Bellefontaine of Chicagoland Home InspectorsFor complete training with visual materials, practice exams, and certification support, visit nhiexamprep.com© 2025 National Home Inspector Exam Prep Podcast.
