The roof to wall intersection is the junction where building aesthetics meets structural performance, air and moisture management, energy efficiency, construction trade sequencing, and operational maintenance. At such a critical interface, proper parapet detailing, installation coordination, and execution are paramount.
How do you achieve performance at the roof to wall interface without compromising the aesthetics over the edge of the roof? How can the design anticipate the construction phase coordination efforts and sequencing between masons, carpenters, and roof and wall subcontractors, and provide a constructible and integrated building solution? This session will provide guidelines to successfully navigate these often competing interests and provide strategies for achievable performance through design and specification without compromising the aesthetics with distracting details over the edge of the roof.

Learning Objectives:

1. Understand requirements to manage condensation risk through air barrier continuity.
2. Understand code requirements and how to achieve compliance.
3. Outline design and specification requirements to set achievable performance.
4. Develop critical details where the roof and wall intersect.
