Abstract
Issues surrounding reports of condensation beneath light-colored single-ply roof membranes in some climates has been one of the more discussed industry-related topics over the past decade. Looking back, it appears that, building owners or tenants would report a mysterious “leak” or water intrusion into interior conditioned space and simply suspected that it was a leak likely associated with a weather event. As more and more of these situations were reported and then evaluated by the roofing contractor or professional roofing consultant certain patterns began to emerge in various climactic zones and general type(s) of roof assemblies.
