Examination of a Blistered Built-Up Roof: O'Neill Building, Hanscom Air Force Base
Blisters are a common defect in built-up roofs. In January 1983 we examined a recently constructed built-up roof at Hanscom Air Force Base in Bedford, Massachusetts, to determine the cause of its blisters. We used an infrared scanner, took ten core samples, conducted visual examinations, and cut open three blisters. Our findings show that the membrane is essentially wartertight and that the blisters were caused by voids that were built into the roof during construction. Poor workmanship and cold weather are the likely causes of the voids. With proper maintenance reasonable performance can be achieved from this imperfect roof. (Author)
