Infrared Roof Moisture Surveys
We utilize FLIR infrared cameras to detect and document moisture located within a roofing system. The presence of moisture in a low-slope roofing system causes changes in the thermal properties of the roof. We utilize hand-held or drone-mounted infrared cameras to perform our surveys, depending on the client's needs, location, and local/federal regulations. Infrared surveys are conducted at sunset to detect evidence of latent moisture in the roof due to changes in the roofing system's thermal conductivity and thermal capacitance.
This non-destructive testing allows our technicians to determine if an area of the roof has moisture. If moisture is present, the affected area is outlined with spray paint and recorded with an infrared image and details of the problem area. We create a report for future repairs, legal documentation, or quality assurance. In addition, the report can be included in real estate transactions, insurance claims, pre-bid documentation, and legal cases.
Nuclear Roof Moisture Survey
We use nuclear technology to identify latent moisture within the roofing system of a building where infrared is not effective. Nuclear (radioscopic) roof moisture surveys are a form of non-destructive testing used to detect and document moisture content within a roofing system. Nuclear surveys provide an effective test method for roofing systems where infrared thermography is ineffective, such as those covered with high-density ballast or pavers or facilities with multiple roof systems in place.
Unfound trapped moisture can lead to health issues due to mold growth in those areas. A nuclear survey can distinguish between multiple moisture levels and is a very accurate method to discover hidden moisture in ballasted roofs. In our final report and on the roof plan drawings, we detail the extent and location of the moisture areas.
