In basic roofing design vapor retarders and air barriers play a crucial role in reducing air leakage and enhancing roof system performance. However, their benefits extend beyond simple air sealing. This course explores the impact of new innovative technology: permeable vapor retarders and air barriers on moisture management, energy efficiency, and wind uplift resistance in low-slope roofing assemblies. Attendees will gain insights into moisture infiltration, air movement, and the risks associated with condensation buildup, material degradation, and loss of R-value in the roofing assembly. The presentation will cover strategies for proper design and placement of a permeable vapor retarder to mitigate condensation buildup and premature roof failures. Recent research findings will highlight how advanced moisture control solutions, such as permeable vapor retarders, enhance long-term roof resiliency and durability, lowering total cost of ownership.

Upon completion of this course, the Learner should be able to:

• Understand the function of vapor retarders, permeable vapor retarders, and the main component layers in low-slope roof assemblies.
• Examine vapor drive and how moisture vapor moves through roofing systems.
• Learn how to determine the need for a permeable vapor retarder and best practices for design and specification.
• Assess the impact of permeable vapor retarders and air barriers on condensation buildup, thermal performance, and wind uplift resistance.
• Identify common misconceptions about air and moisture control layers and how to effectively mitigate moisture-related roof assembly failures.
