Flat roofs are responsible, practical, and stylish — Nonetheless they will also be tough. not like sloped roofs, where by leaks frequently show up quickly, flat roof leaks can stay concealed for months beneath levels of insulation and membranes. h2o may well journey horizontally through the roofing program, demonstrating up as stains significantly from its supply. By the time the problem becomes seen, sizeable internal damage may already have happened.
This is when infrared roof scanning comes in. It’s Among the most Superior, non-destructive ways to Find dampness and detect concealed leaks just before they escalate into expensive repairs. For Canadian property entrepreneurs managing Excessive weather, infrared engineering has become a game-changer in flat roof servicing and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) takes advantage of warmth-sensing cameras to establish temperature variances to the surface of the roof. The fundamental basic principle is easy: wet products retain heat otherwise than dry types.
once the Solar warms a roof during the day, regions that contains trapped moisture soak up and maintain heat for a longer time. just after sunset, as the roof cools, Individuals damp spots launch warmth additional little by little — generating visible “scorching spots” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks under membranes.
-
regions with saturated insulation.
-
ruined or delaminated roofing materials.
-
Drainage troubles or trapped dampness in close proximity to seams.
This non-invasive technique permits exact detection without having chopping or harmful the roofing system.
