Thermal imaging uses infrared technology to detect very smalldifferences in temperature. Every material has a unique thermal signature and when moisture, heat, cold, or wood destroying insects are introduced into the structure the thermal signature changes. The changes can be subtle or dramatic but with this incredible thermal image scanning technology the thermal signatures are detectable where they wouldn’t be able to be seen with the naked eye.
Thermal image scanning technology is now being used to evaluate residential and commercial structures. As a non-invasive testing tool it can quickly help discern where there are suspected issues. This can help to limit the areas where time consuming further evaluation and destructive discovery is needed.
Moisture equals mold!
The Photo to the right is of a brick area above a mantle where there is a water leak on the roof at the area of the chimney. This goes undetected with the naked eye however was picked up using Thermal Imaging.
When moisture intrusion is located and corrected then further structure deterioration and widespread growth of mold can also be stopped. Thermal Imaging can greatly help in the detection of structural damaging leaks. Please remember that every day that a leak goes undetected the damage is increased. When detected early the structural repairs and any needed mold remediation are significantly less costly.
Moisture Detection in Walls and Ceilings
As demonstrated above, thermal imaging is a great tool that helps to identifying water damage in walls, floors, and ceilings. By detecting the difference in temperature between a wet area and the surrounding dry areas thermal imaging can help detect moisture issues that would not be visible during a visual inspection. It is also great at identifying areas where the insulation contractor failed to insulate adequately.
Wood Destroying Insect Activity
Significant wood destroying insect activity can be detected using this technology due to the heat generated by active infestations. That’s right, active termite activity produces a great deal of heat that is often visible to the infrared camera. Minor activity may not be detectable but areas not normally visible to the naked eye can be identified, and then a more invasive or technically exhaustive inspection can be carried out by the appropriate professional.
Flat Roof Inspections
If you have a leak on a new to mid life flat roof and have been told that a new roof is needed, then call us first. We may be able to save you a substantial amount of money. Thermal imaging can be used to detect the precise location of the leak and mark the affected area so that repairs can be made to the leaking area. Obviously, if the roof is older then you should forgo the thermal imaging and invest in the needed new roof.
