Abstract
The roofs and upper story walls of buildings 745E, 752 and 756 at the U.S. Military Academy at West Point, N.Y., were surveyed with a hand-held infrared camera to locate sources of reported wall leaks. An electrical resistance probe was used to determine the relative level of moisture in wall components. Several 3-inch-diameter core samples of each roof were obtained to verify suspected moisture conditions and to examine the roof membrane in cross section. Wet areas of each roof were outlined with white spray paint. Wall leaks are believed to be caused by wind-driven rain entering the parapet walls in locations where the decorative glaze coat has spalled off. Recommendations for maintenance of these buildings are based on information derived from the infrared survey, electric resistance readings, core samples and visual examinations.
