Flat roofs are reputable, practical, and stylish — Nonetheless they can even be tough. in contrast to sloped roofs, wherever leaks usually surface immediately, flat roof leaks can remain hidden for months beneath layers of insulation and membranes. h2o may travel horizontally from the roofing method, displaying up as stains far from its resource. by the point the challenge becomes obvious, substantial interior harm may well have already got happened.
This is where infrared roof scanning comes in. It’s The most Highly developed, non-destructive methods to Track down dampness and detect hidden leaks just before they escalate into high-priced repairs. For Canadian property owners working with Severe weather conditions, infrared technologies happens to be a match-changer in flat roof maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses warmth-sensing cameras to detect temperature differences over the surface area of a roof. The essential basic principle is straightforward: moist materials retain heat in a different way than dry types.
in the event the sun warms a roof throughout the day, locations made up of trapped dampness take up and keep heat longer. just after sunset, as the roof cools, All those damp places release warmth additional slowly and gradually — making seen “warm spots” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
