Flat roofs are trusted, sensible, and trendy — but they can also be challenging. Unlike sloped roofs, where by leaks generally look swiftly, flat roof leaks can keep on being hidden for months beneath levels of insulation and membranes. drinking water may well travel horizontally through the roofing system, showing up as stains significantly from its source. By the time the issue results in being obvious, substantial inside damage could already have transpired.
This is where infrared roof scanning is available in. It’s Probably the most Superior, non-harmful methods to Identify humidity and detect concealed leaks just before they escalate into high priced repairs. For Canadian property proprietors dealing with extreme weather, infrared technology happens to be a sport-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) takes advantage of heat-sensing cameras to recognize temperature dissimilarities over the surface of the roof. The essential theory is easy: wet elements keep warmth otherwise than dry ones.
When the sun warms a roof throughout the day, regions containing trapped humidity absorb and hold heat more time. After sunset, as being the roof cools, People moist spots release heat additional slowly but surely — developing obvious “very hot spots” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
regions with saturated insulation.
-
Damaged or delaminated roofing products.
-
Drainage issues or trapped humidity near seams.
This non-invasive strategy permits exact detection devoid of reducing or detrimental the roofing system.
Why Infrared Scanning Is Essential for Flat Roofs
