Flat roofs are reputable, sensible, and classy — but they can be tough. compared with sloped roofs, the place leaks often show up quickly, flat roof leaks can keep on being hidden for months beneath layers of insulation and membranes. drinking water may possibly vacation horizontally with the roofing process, displaying up as stains considerably from its resource. By the time the trouble results in being visible, sizeable inside damage might already have occurred.
This is when infrared roof scanning is available in. It’s Probably the most Superior, non-damaging methods to Track down dampness and detect hidden leaks before they escalate into pricey repairs. For Canadian residence house owners handling extreme temperature, infrared technological innovation has grown to be a game-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes heat-sensing cameras to recognize temperature distinctions around the area of a roof. The fundamental theory is simple: moist elements keep warmth in a different way than dry types.
once the sun warms a roof during the day, spots made up of trapped moisture take in and keep warmth extended. right after sunset, given that the roof cools, Those people damp places release heat a lot more gradually — making visible “scorching spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks below membranes.
-
locations with saturated insulation.
