2026 Convention Session Course: Condensation Control - Designing Resilient Low-Slope Roof Assemblies (Wood S., Walters M.)

Condensation Control: Designing Resilient Low-Slope Roof Assemblies
(Wood S., Walters, M.)

Course Overview
This session was originally presented at the 2026 IIBEC Convention & Trade Show in Sacramento, CA. 

This course includes the following required components.

• recording of the live session
• summative assessment consisting of 10 multiple-choice questions
• course evaluation survey

Description
Effective moisture control is essential for extending the service life and maintaining the performance of low-slope commercial roofing systems. While traditional vapor retarders and air barriers help reduce air leakage, we will discuss newer technologies that offer more adaptive solutions that align with today’s roof performance demands. This session explores the next generation of moisture management, permeable vapor retarders and air barriers, and their role in mitigating moisture intrusion, improving energy efficiency, and enhancing wind uplift resistance. Attendees will examine the science behind condensation and its often-overlooked consequences, including material degradation, reduced thermal performance, and premature roofing failures driven by uncontrolled moisture-laden air movement. Through current research and real-world case studies, this presentation highlights how strategic design and installation of these advanced materials can significantly increase roof resilience, extend system longevity, and reduce long-term operational costs—ultimately offering better protection for the entire building envelope.
