Flat roofs are reputable, realistic, and classy — but they can also be challenging. contrary to sloped roofs, exactly where leaks often seem speedily, flat roof leaks can stay concealed for months beneath levels of insulation and membranes. Water may possibly journey horizontally from the roofing procedure, demonstrating up as stains considerably from its resource. by the point the challenge turns into noticeable, important internal harm may possibly already have happened.
This is where infrared roof scanning comes in. It’s The most Sophisticated, non-harmful methods to Identify dampness and detect hidden leaks ahead of they escalate into pricey repairs. For Canadian house house owners coping with Serious weather, infrared technological know-how is now a recreation-changer in flat roof maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) employs warmth-sensing cameras to recognize temperature distinctions on the surface of the roof. The essential basic principle is easy: damp resources retain heat in a different way than dry types.
once the sun warms a roof throughout the day, locations containing trapped humidity soak up and maintain heat extended. After sunset, because the roof cools, People wet spots launch heat much more bit by bit — generating obvious “scorching spots” on an infrared image.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks less than membranes.
-
spots with saturated insulation.
-
broken or delaminated roofing supplies.
-
Drainage difficulties or trapped moisture in close proximity to seams.
This non-invasive strategy permits accurate detection with out slicing or detrimental the roofing system.
Why Infrared Scanning Is Essential for Flat Roofs
