Abstract
The roof of building 208 at the Rock Island Arsenal was surveyed for wet insulation using a hand-held infrared camera. Areas of wet insulation were marked with spray paint on the roof and 3-in-diameter core samples of the built-up membrane and insulation were obtained to verify wet and dry conditions. Roof defects uncovered during a visual inspection also were marked with spray paint. The majority of the wet areas detected are associated with flashing flaws, which are considered responsible for the wet insulation. Recommendations for maintenance of this roof are based on information derived from the infrared survey, core samples and visual examination.
