Description
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
Over half of roof re-cover projects now omit high-density cover boards, with many new membranes—such as fleece-backed and self-adhering systems—adhered directly to aged, weathered substrates. This session examines the performance trade-offs of these practices, including reduced durability, compromised adhesion, and greater sensitivity to substrate irregularities. Attendees will gain insight into how value engineering impacts system longevity and how the design community can advocate for high-performance solutions. Through technical analysis and practical examples, the presentation highlights strategies to optimize system performance while navigating economic pressures and evolving industry norms.

Objectives
At the conclusion of this activity, the learner will be able to:
1. Identify the common reasons that high-density cover boards are omitted in modern roof re-cover applications and associated industry trends.
2. Evaluate the performance impacts of adhering membrane systems directly to existing weathered substrates without intermediate layers.
3. Analyze the risks and limitations of value-engineered roofing designs in terms of long-term durability, adhesion, and thermal performance.
4. Apply best practices and design strategies to promote high-performing roofing systems within the constraints of budget-driven project environments.
