Narrow Roof Design Challenges
Narrow roofs and other façade articulations are often designed and detailed with waterproofing characteristics similar to adjacent vertical wall surfaces, leaving the narrow roof assembly with insufficient waterproofing performance and risk of leakage. Horizontal surfaces in these assemblies experience environmental conditions and exposures that demand the waterproofing materials and detailing of roofs. The presenters will identify narrow roof waterproofing challenges, discuss waterproofing design and detailing considerations, and review case studies from recently completed projects. This presentation will inform designers how to approach these conditions and improve building owners’ understanding of the operations and maintenance implications of these features.
