This course explores one of the most technically challenging intersections of the building enclosure: the roof-to-wall transition. Participants start with an overview of building science fundamentals: the four control layers (water, air, thermal, and vapor) and mitigating the energy loss and moisture issues associated with air leakage. We will also discuss wind resistance requirements. Through the use of specific examples, the presentation evaluates how different building types, interface types, and maintenance requirements can impact the design of the transition. The course provides guidelines to follow when designing, specifying and constructing these details to ensure design and code requirements are met while ensuring the long-term performance of the building enclosure.

Learning Objectives:

1. Describe the requirements for managing moisture, air, vapor, and thermal continuity at building interfaces.
2. Design interface details that meet air, water, and thermal control requirements for current and future projects.
3. Compare the performance characteristics and chemical compatibility of roofing and wall membranes to support durable adhesion and long-term material integrity at transitions.
4. Develop design and specification criteria that define performance standards for roof-to-wall details.
