Roof Top

Aerial Roof survey. Using the spot tool in the software provides us the ability to scan each image after it has been taken to find hot or cold areas. This is a dry roof but see all the cold areas. There is water underneath the membrane of the roof. Many roofs need to be replaced prematurely due to moisture damage from leaks and improper installation. Thermal infrared inspections are non-contact, non-destructive testing procedures. This technology is used in finding damaged portions of roofing structure so they can be repaired before water damage rots the entire roof. A high res camera allows a professional to scan large areas of roof from a distance. Thermal infrared roof inspections work on the principal that different materials in the roof have different thermal mass. In the daytime, the sun heats the roof structure. After the sun sets, the roof begins to cool. If there is a leak in the roof membrane, the insulation inside the roof will become wet. The wet insulation has a higher thermal mass than the rest of the dry roof structure. As a result of this difference, the wet areas will retain heat energy longer than other areas providing the infrared inspector with a clear picture of the damaged area.
