Uses for Thermal Imaging in Construction and Roofing
Flat Roof Inspections
Flat roof IR inspections reveal early moisture damage in roofing insulation, allowing for an easier and less costly repair that will prevent premature roof replacements that normally result from moisture damage, leaks, and improper installation. Infrared thermography has a proven track record for finding damaged portions of roofing structures so they can be repaired before water damage rots an entire roof. Thermography is a non-contact testing method that does not require drill holes to test for damage. Additionally, the non-contact nature of infrared thermography allows for aerial inspections of large roofing structures.
Flat roof structures are the standard in industrial settings. Of the millions of square feet of roof installed each year, it has been estimated that up to 40% will develop problems within the first year of service. The average life span of these roofs is seven years, but it is estimated that they could last as long as twenty years when correctly installed and maintained. An investment in infrared imaging will provide returns of roof repair savings by prolonging the life of your flat roof structure. Thermal infrared inspections are non-contact and non-destructive testing procedures. The IR camera allows a professional thermographer to scan large areas of roof from a distance. Traditional roof inspection methods require a grid type contact search that takes a long time to complete or may even involve drilling holes in the roof membrane.
How IR Roof Inspections Work
Infrared roof inspections apply the principal of differential heat. The different materials that make up the entire 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 maintain heat energy longer than other areas providing the infrared inspector with a clear picture of the damaged area. The temperature difference between damaged and "dry" roof is very small (typically 2-4 degrees). Because of this, it is vital that you have an experienced professional thermographer perform your inspection or a properly trained staff. Sierra Pacific Innovations can provide you with either a certified infrared roof inspector or furnish your organization with a high quality thermal camera and the appropriate training for your staff.
