06 - LOW SLOPE ROOF COVERINGS (PART 2)

Send us Fan MailModern low slope roofing systems take the spotlight in this episode. We begin with modified bitumen roofing - polymer-modified asphalt-based membrane systems used since the mid-1970s with expected service life of 12-20 years for single membrane residential systems. Learn to distinguish modified bitumen from mineral-surfaced roll roofing and understand proper seam installation using heat or adhesive. Next, we explore polyurethane foam roofing - a unique spray-applied system that serves as both roofing and insulation. Discover why the protective elastomeric top coating must be reapplied every 15 years and why this system requires precise installation techniques. Finally, we examine single-ply membrane roofing, focusing on EPDM (Ethylene Propylene Diene Terpolymer) - the rubberlike thermoset membrane with a 30+ year service life. For each system, we cover typical problem locations including penetrations, equipment mounting issues, and transitions to vertical walls. Learn proper repair methods, common defects like ponding water, blistering, and deteriorated flashings. This episode is essential for understanding modern low slope roofing technology and maintenance requirements.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.
