Would you prefer to repair or replace only the damaged portions of your low-slope roof instead of complete resurfacing?
Are you looking for more visual evidence to help with the locating the source of water leaks in your roof before any more building damage or propagation of mold occurs?
IR thermography is an excellent application for analyzing low-sloped rubber membrane roofs. The actual IR survey is performed after sunset to optimize the scan findings. Trapped water in roof membranes dissipates its heat energy at a slower rate than the balance of the roof materials due to the water's high thermal capacity.
The survey of a flat roof generally requires three trips to the inspection site. During the daylight a safety walk occurs in conjunction with a visual review of areas of presumed concern. The IR survey occurs after sunset, at least 24 hours after the last precipitation, to minimize the masking of thermal energy by stagnant water or residual moisture in the pebbles. This must also be performed in low wind conditions as the mechanical energy of the wind moving across the roof's surface aids in masking the infrared findings. The observed areas are typically denoted with a spray paint to identify areas requiring repair from apparent water ingress. A follow-up visit to the jobsite occurs to document, with a digital camera, the denoted areas highlighted with paint.
