Roof Moisture Surveys Nuclear Method Roofing professionals have successfully used non-destructive testing techniques since the 1970s to determine the extent and location of wet insulation within built-up and single ply roofs. Of the three types of moisture detection instruments, only nuclear gauges have the advantage of working with all of the common roofing membrane/insulation combinations. The nuclear method is the most accurate technology that can be used to detect elevated levels of moisture under a ballasted EPDM system. In a typical application, a 10’ x 10’ grid pattern is marked on the roof with chalk. A reading is taken at each grid intersection and recorded in field data sheets. A final report, with CADD drawings, details the extent and location of elevated moisture levels. Nuclear technology can operate in a wide range of weather conditions and on any type of slope roof. Because the work is conducted during the day, scheduling and safety concerns are minimized. Nuclear is the only method that distinguishes between two or more levels of moisture. The final report clearly details where elevated levels of moisture have been detected. This report can be used in repair specifications with confidence. Infrared Method Roofing contractors, building owners, and others utilize our roof inspection service to prevent major roof repairs. Infrared thermography, along with other non-destructive testing techniques, is used to identify temperature differences created by saturated insulation in the roof assembly. Problem areas are marked on the roof and the findings are presented in a CADD report. Findings are confirmed using electric capacitance or nuclear instruments, so core samples are unnecessary. This service allows business owners to save thousands of dollars. Instead of spending an enormous amount of money to replace the entire roof, our infrared inspection allows customers to identify and replace only the problem areas. Thermo-Scan Inspections uses cutting edge infrared equipment and nuclear technology, and has certified thermographers with over 20 years of roof inspection experience.
