Flat roofs are reputable, simple, and trendy — However they can also be challenging. as opposed to sloped roofs, exactly where leaks normally seem swiftly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. h2o may well vacation horizontally in the roofing technique, showing up as stains considerably from its resource. by the point the challenge gets to be obvious, significant interior destruction might already have occurred.
This is where infrared roof scanning comes in. It’s Just about the most Innovative, non-destructive methods to Find dampness and detect hidden leaks prior to they escalate into costly repairs. For Canadian property entrepreneurs addressing Intense weather, infrared technological know-how has become a recreation-changer in flat roof servicing and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses heat-sensing cameras to detect temperature distinctions about the floor of the roof. The basic basic principle is simple: soaked elements retain heat in another way than dry types.
once the Sunshine warms a roof during the day, parts that contains trapped dampness take in and hold heat for a longer time. After sunset, as the roof cools, All those damp spots release heat more little by little — making noticeable “scorching spots” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks less than membranes.
-
spots with saturated insulation.
-
ruined or delaminated roofing supplies.
-
Drainage challenges or trapped moisture around seams.
This non-invasive approach allows for exact detection with no cutting or damaging the roofing system.
Why Infrared Scanning Is Essential for Flat Roofs
