Abstract
Many low-slope roof assemblies are designed without proper consideration of whether an impermeable vapor retarder layer is necessary to prevent moisture accumulation. In some instances, this results in unintended moisture accumulation within and possible premature deterioration of the roof system. Following are guidelines designers should evaluate when considering whether to include a vapor retarder layer in their roof system designs to prevent unwanted moisture accumulation.
