Course Description: AEC Daily: Roofs and Condensation: A Practical Approach for the Design Professional
With the advent of “cool” single-ply roofs featuring heat-reflective exterior surfaces and the use of mechanical attachment, new questions have emerged concerning the internal forces at play within the roofing system, especially in regard to vapor movement and the potential for moisture condensation within the roof. This course reviews the fundamentals of vapor movement in roofing systems, current roof condensation research, and the tools available to assess roof condensation. It also provides the building design professional with strategies to deal effectively with moisture movement within the roofing system.
Discuss the basic principles behind the science of vapor movement in roofing systems to identify the key factors that may lead to moisture accumulation in roofing systems and inhibit the long-term performance of the roof.
Evaluate research studies to determine the actual incidence of moisture condensation and recognize the factors that may lead to the accumulation of moisture within single-ply roofing systems.
Demonstrate how to use available design tools to evaluate moisture movement in roofing systems and use this information to mitigate roof condensation.
Identify design strategies to reduce the potential for moisture accumulation in roofing systems and prevent premature roofing failure.
