stresses in built-up roofing membranes are caused by differential movements due to loads, temperature variations, and moisture changes. if excessive over a period of time, they cause premature failure of the membrane, the most common symptom being blistering and interply separation. the effect of moisture and applied pressure on the interply adhesion of built-up roofing membranes and on the development of blisters has been investigated some 200 specimens from different samples of built-up roofing membranes made with conventional type 15 organic felt plies or with cotton fabric plies (denim cloth) were tested at varying amounts of moisture, surface pressure, and rate of loading. 13 refs
