Flat roofs are trusted, sensible, and trendy — Nonetheless they may also be tough. as opposed to sloped roofs, where by leaks normally look swiftly, flat roof leaks can continue to be hidden for months beneath layers of insulation and membranes. drinking water may possibly travel horizontally through the roofing method, displaying up as stains considerably from its supply. By the time the situation will become seen, substantial inner damage could already have occurred.
This is when infrared roof scanning is available in. It’s one of the most Sophisticated, non-destructive techniques to Find humidity and detect hidden leaks before they escalate into high priced repairs. For Canadian property house owners coping with extreme weather conditions, infrared technological innovation has become a match-changer in flat roof maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) works by using heat-sensing cameras to establish temperature dissimilarities over the area of a roof. The essential basic principle is straightforward: soaked products retain heat in different ways than dry ones.
if the sun warms a roof throughout the day, regions containing trapped dampness take up and hold warmth more time. After sunset, since the roof cools, Those people wet spots release heat more little by little — creating noticeable “very hot spots” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
