Managing Roofing Risks: Air and Vapor Control
Learning Objectives:
- Recognize when, where, and why to use an air barrier vs. vapor barrier vs. vapor permeable retarder in low-slope roofing applications.
- Describe the technology changes of low-slope roofing systems over time and their importance to building performance.
- Gain clarity on how building science fundamentals, specifically heat, air, and moisture management, influence both energy efficiency and compliance with regulatory requirements.
- Identify how to mitigate common issues from moisture and air movement that impact occupant’s health and safety.

Every year, contractors install millions of square feet of commercial roofing for both new construction and re-roofing projects. Traditionally, low-slope roofing systems have prioritized vapor restriction over air tightness. In this newly accredited AIA presentation, we will delve into the advancements in air barrier technology and permeable vapor retarder membranes, and their influence on building performance. This webinar aims to equip you with the insights needed to make informed choices between air/vapor retarders and permeable vapor barriers for low-slope roofing, enhancing your proficiency in creating resilient and sustainable building envelopes.
