New Air Barrier Requirements for Re-Roofing

As energy codes evolve, so do the requirements for roof system performance — especially during reroofing projects. This course explores the latest updates to building codes and standards that introduce air barrier requirements when replacing existing roofs. Attendees will learn why air control matters, how it interacts with moisture and thermal layers, and what design professionals and contractors need to consider to ensure code compliance, building durability, and energy efficiency.

Learning Objectives:

1. Identify key code changes related to air barriers in reroofing.
2.  Understand the building science principles behind air leakage and roof system performance.
3.  Evaluate existing roof conditions to determine air barrier requirements.
4.  Review best practices for detailing and integrating air barriers during reroofing.
