AreaScanIR™ Direct
This roof maintenance service is for roof owners, property managers, building managers and third parties who want to buy imagery of a specific roof or a set of roofs in an area to find out the condition of those roofs. Our imagery shows the extent of roof moisture contamination for maintenance purposes, roof asset management, and historical forensics purposes.
AreaScanIR™ Direct pricing is based on the size of the roof(s) and how much detail is required. We have experts who can select roofs based on any criteria you choose. For instance, you may want a particular type of roof in a given area that shows moisture damage that are between 30,000 SF and 100,000 SF.
We go through the imagery, adjusting the brightness and contrast, and save/deliver just the type of roofs you are looking for. If you would like expert analysis of the condition of your roofs, we can create CAD drawings of your buildings and outline wet areas on the roofs.
In a matter of hours, you could have infrared imagery and CAD analysis of roofs in a given area…
Understanding Aerial Infrared Roof Imagery
Infrared Thermography (IRt) is a well-known and proven non-destructive testing (NDT) method used to find moisture trapped in most roof types. We have flown over large areas of cities with high concentrations of flat and low-sloped roofs and we have collected thermal infrared imagery. In some areas, we have also collected visible light imagery as well. We are willing to license the use of this imagery to be used by your company for specific purposes.
When an image is taken by our infrared camera, it is digitally saved to a hard drive and later converted to a digital image file with the help of a computer. The image may then be modified in a number of ways to enhance its value to the end user. The highest resolution infrared images are usually found on the raw digital files, while the mosaic ortho-rectified imagery may be useful as a convenient reference when making building roof drawings or accompanying roof reports.
Areas of roof moisture contamination often manifest themselves as warmer (lighter colored) areas that may be nebulous in shape and sometimes mottled in appearance, although they are commonly found in linear or puddle-like shapes. The linear shapes many times follow low areas, drainage routes, roof edges and seams. Puddle-like round or oblong shapes often form around roof penetrations such as mechanical equipment, standpipes, vents and drains. The wet areas are lighter in color because the latent heat (from daylight sunshine) in the trapped water mass is greater than in the dry, functioning insulation or roof substrate. After sunset when the roof structure cools down, wet areas of roof insulation and other wet materials continue to radiate heat because of their mass, higher thermal conductivity, and specific heat capacity, which allows our sensitive infrared cameras to detect the sources of heat and record them for later analysis.
