Flat roofs are reputable, realistic, and trendy — However they can be challenging. as opposed to sloped roofs, where by leaks normally seem immediately, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may perhaps travel horizontally in the roofing procedure, showing up as stains much from its source. by the point the situation gets noticeable, significant inside problems may well already have happened.
This is where infrared roof scanning comes in. It’s Just about the most advanced, non-damaging techniques to Find dampness and detect concealed leaks in advance of they escalate into expensive repairs. For Canadian house owners dealing with Intense climate, infrared technological know-how is becoming a match-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) utilizes heat-sensing cameras to establish temperature differences on the surface of the roof. The basic principle is straightforward: soaked supplies keep heat differently than dry types.
once the Solar warms a roof throughout the day, regions containing trapped moisture absorb and maintain heat for a longer time. right after sunset, as being the roof cools, These soaked spots release heat more slowly — generating visible “scorching places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
regions with saturated insulation.
-
ruined or delaminated roofing materials.
-
Drainage concerns or trapped moisture in close proximity to seams.
This non-invasive solution allows for precise detection with no cutting or damaging the roofing process.
