Flat roofs are dependable, functional, and trendy — but they can even be challenging. as opposed to sloped roofs, the place leaks usually appear speedily, flat roof leaks can continue being hidden for months beneath levels of insulation and membranes. h2o may travel horizontally in the roofing process, showing up as stains significantly from its supply. by the point the problem gets visible, significant inner harm may well already have happened.
This is where infrared roof scanning is available in. It’s one of the most Innovative, non-damaging strategies to Find dampness and detect concealed leaks ahead of they escalate into pricey repairs. For Canadian assets owners addressing Severe climate, infrared technological know-how happens to be a recreation-changer in flat roof routine maintenance and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) works by using warmth-sensing cameras to recognize temperature differences about the surface area of the roof. The fundamental principle is simple: moist elements keep warmth in different ways than dry types.
in the event the Sunshine warms a roof during the day, places made up of trapped humidity soak up and hold heat extended. soon after sunset, as the roof cools, These damp spots launch heat a lot more slowly but surely — developing noticeable “sizzling 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 resources.
-
Drainage issues or trapped dampness near seams.
This non-invasive method permits precise detection with out chopping or harming the roofing program.
