09 - SKYLIGHTS

Send us Fan MailOur final episode explores skylights - windows in roofs that bring natural light but require careful installation and maintenance. Learn the technical definition: any glazed opening sloped more than 15° from vertical. We cover both rectangular factory-assembled units and round dome (tubular) skylights. Discover why glazing safety requirements mandate laminated, tempered, wired, or heat-strengthened glass, and when protective screens are required. We discuss the solar heat gain challenges skylights create, their impact on HVAC systems, and how Low-E glazing and shade screens help. Proper installation is critical - we explain why a minimum 4-inch tall curb is recommended (and required for slopes less than 3:12), proper flashing techniques that mirror chimney flashing, and the importance of correctly framing ceiling joists and rafters around skylights. Learn why cutting trusses requires engineered repairs and why improper skylight chase insulation is a common defect. We identify typical problems including glazing damage, leak issues, condensation that mimics leaks, ice dam formation, and debris accumulation. This episode provides comprehensive guidance for evaluating, installing, and maintaining skylight systems. The perfect conclusion to our roofing series!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.
