The Effects of Moisture on Built-Up Roofing Membranes

Source

The effect of entrapped moisture on blistering, buckling, and interply adhesion of built-up roofing membranes is well known. Shown in this paper is the added effect of moisture transmission into, and absorption by, the components of an otherwise dry system, using dry cup water vapor transmission measurements. Variations in the absorbed equilibrium moisture contents, and their vapor pressures, with changing environmental conditions seems to correlate well with observed roof behavior.
