Flat roofs are responsible, useful, and classy — but they can even be tough. contrary to sloped roofs, where leaks generally appear speedily, flat roof leaks can keep on being hidden for months beneath levels of insulation and membranes. h2o may travel horizontally in the roofing system, demonstrating up as stains far from its supply. by the point the problem will become obvious, sizeable interior injury could already have happened.
This is when infrared roof scanning comes in. It’s one of the most State-of-the-art, non-harmful ways to Track down moisture and detect concealed leaks prior to they escalate into pricey repairs. For Canadian home homeowners handling Excessive weather conditions, infrared engineering is becoming a match-changer in flat roof maintenance and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) uses heat-sensing cameras to identify temperature distinctions over the area of the roof. The fundamental principle is straightforward: damp products keep heat in a different way than dry ones.
When the sun warms a roof during the day, areas containing trapped dampness take in and maintain heat extended. following sunset, since the roof cools, People wet spots launch heat more slowly but surely — developing visible “warm spots” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
regions with saturated insulation.
-
harmed or delaminated roofing resources.
-
Drainage problems or trapped moisture near seams.
This non-invasive tactic allows for precise detection without the need of slicing or detrimental the roofing process.
