The roof meets the wall at the intersection of design aesthetics, functionality, durability, construction sequencing and maintenance. Each of these perspectives are critical for the long-term performance of the building, but are often at odds with one another. At such a critical interface, proper parapet detailing, installation coordination and execution are paramount. Continuity of water, air, thermal and vapor control layers are necessary for long-term performance. This session will provide guidelines to successfully navigate these competing interests and provide project specific strategies for achievable performance through design and specification without compromising the aesthetics with distracting details at the parapet.
