Flat roofs are trustworthy, functional, and trendy — However they can even be tricky. as opposed to sloped roofs, in which leaks frequently show up quickly, flat roof leaks can continue being hidden for months beneath layers of insulation and membranes. drinking water could vacation horizontally throughout the roofing system, demonstrating up as stains significantly from its resource. By the time the issue turns into visible, significant interior damage may already have happened.
This is when infrared roof scanning is available in. It’s Just about the most advanced, non-destructive methods to locate dampness and detect hidden leaks just before they escalate into high-priced repairs. For Canadian home owners coping with Extraordinary weather conditions, infrared technology is now a activity-changer in flat roof maintenance and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) employs heat-sensing cameras to determine temperature distinctions to the surface of a roof. The basic principle is easy: wet materials keep heat otherwise than dry types.
When the Sunshine warms a roof throughout the day, regions containing trapped humidity absorb and hold heat for a longer time. just after sunset, as being the roof cools, Those people moist spots release heat much more gradually — producing visible “hot spots” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks less than membranes.
-
locations with saturated insulation.
-
ruined or delaminated roofing components.
-
Drainage troubles or trapped moisture in close proximity to seams.
This non-invasive approach allows for exact detection devoid of cutting or harmful the roofing system.
Why Infrared Scanning Is Essential for Flat Roofs
