Flat roofs are reliable, sensible, and classy — Nevertheless they can even be tough. not like sloped roofs, the place leaks typically surface speedily, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. drinking water may well journey horizontally in the roofing technique, displaying up as stains significantly from its resource. by the point the situation will become noticeable, sizeable inner hurt may perhaps have already got happened.
This is when infrared roof scanning comes in. It’s Probably the most Innovative, non-destructive methods to locate humidity and detect hidden leaks ahead of they escalate into high priced repairs. For Canadian assets entrepreneurs addressing Extraordinary weather, infrared technology is now a game-changer in flat roof upkeep and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) employs warmth-sensing cameras to establish temperature dissimilarities on the surface of the roof. The essential theory is straightforward: moist resources keep heat in a different way than dry kinds.
if the Solar warms a roof throughout the day, parts containing trapped dampness take up and maintain warmth more time. following sunset, as the roof cools, Individuals moist places release warmth extra slowly — making visible “scorching spots” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks underneath membranes.
-
locations with saturated insulation.
