Moisture Control and Durability in Hybrid Light-Frame Panelized Roof Systems

National Online Seminar

Hybrid light-frame panelized roof systems are widely used throughout the U.S. in large industrial warehouses and distribution centers for their economy, constructability, and repeatability—especially when paired with panelized construction. However, long-term performance depends on a clear understanding of the complete roof assembly and its interaction with climate-specific moisture conditions.

This webinar provides a building science–based overview of hybrid light-frame panelized roof assemblies, clarifying how and where moisture accumulation and condensation can occur, and why long-term performance depends on enclosure design rather than material choice alone. Participants will examine detailing and control-layer strategies that support effective drying, prevent mold growth, and protect indoor environmental quality. Through real-world case studies, the session offers actionable approaches that support code compliance, occupant health, and long-term durability across multiple climate zones.

Colin is a Professional Engineer in the United States and Canada and leads RDH’s team in the Western United States. Colin has a broad knowledge of building construction and applies building science principles to analyze and design durable, energy-efficient building enclosures. He shares his experience by regularly speaking about topics related to building science and building enclosure engineering at events across the United States and contributes to industry organizations with the aim of making buildings better. 

Mark Curry, Principal | West Coast Roof Consulting

Mark Curry is Principal at Westcoast Roof Consulting, a full-service roofing and waterproofing consulting firm with more than 200 years of combined industry experience. In his role, Mark provides independent, technically sound guidance to building owners, property managers, and developers across all phases of roofing and waterproofing projects. Known for delivering objective evaluations, clear specifications, and practical solutions that support informed decision-making and successful project outcomes. 

Learning Objectives:

• Understand the mechanisms of moisture transport (air leakage, vapor diffusion, and bulk water) in hybrid light-frame panelized roof assemblies and their impact on condensation risk and indoor environmental quality.
• Differentiate material misconceptions from system-level causes of moisture failures, demonstrating why trapped moisture is not a wood-specific issue.
• Assess regional climate considerations when designing hybrid panelized roof assemblies, including vapor control, insulation placement, and drying potential in cold, mixed, hot-humid, and marine climates.
• Apply transferable design strategies that enable hybrid light-frame panelized roof systems to perform reliably across diverse U.S. regions, supporting broader adoption beyond traditional West Coast markets.

Online Attendees:
