Flat roofs are trusted, realistic, and trendy — However they can be challenging. compared with sloped roofs, in which leaks frequently show up speedily, flat roof leaks can stay concealed for months beneath levels of insulation and membranes. h2o could travel horizontally throughout the roofing program, demonstrating up as stains much from its resource. by the point the situation turns into obvious, major internal hurt might have already got transpired.
This is where infrared roof scanning is available in. It’s One of the more Sophisticated, non-destructive methods to locate humidity and detect concealed leaks in advance of they escalate into pricey repairs. For Canadian house homeowners coping with Serious weather, infrared technologies is now a recreation-changer in flat roof servicing and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) uses heat-sensing cameras to recognize temperature variances on the surface of the roof. The basic theory is simple: wet materials retain warmth in different ways than dry types.
if the Sunlight warms a roof during the day, locations made up of trapped humidity soak up and hold heat longer. just after sunset, because the roof cools, those damp places release heat far more gradually — creating noticeable “incredibly hot places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
regions with saturated insulation.
-
ruined or delaminated roofing components.
-
Drainage troubles or trapped dampness in the vicinity of seams.
