Drainage of Low-Slope Roof Assemblies

While providing adequate drainage on the surface of roofing systems is a fundamental concept, each project has unique challenges that should be addressed early in the design process to avoid problems during construction. This presentation explores some of these challenges, including coordination required for new construction and issues associated with installing tapered insulation on existing roofs.
