Flat roofs are reputable, sensible, and stylish — However they can be difficult. not like sloped roofs, wherever leaks usually look promptly, flat roof leaks can continue being hidden for months beneath levels of insulation and membranes. drinking water might vacation horizontally with the roofing process, displaying up as stains far from its resource. By the time the condition will become visible, major internal injury may possibly already have happened.
This is where infrared roof scanning is available in. It’s one of the most Sophisticated, non-harmful strategies to locate humidity and detect hidden leaks before they escalate into high priced repairs. For Canadian house homeowners managing Extraordinary weather, infrared engineering is now a recreation-changer in flat roof routine maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) uses heat-sensing cameras to establish temperature variations on the area of a roof. The essential theory is easy: moist resources keep heat differently than dry types.
When the Sunshine warms a roof during the day, locations that contains trapped moisture soak up and maintain heat lengthier. soon after sunset, since the roof cools, Those people moist spots release warmth additional gradually — producing obvious “hot places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
parts with saturated insulation.
-
destroyed or delaminated roofing elements.
-
Drainage concerns or trapped dampness around seams.
This non-invasive approach permits exact detection without having chopping or harmful the roofing technique.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, particularly in commercial and multi-residential structures, are specifically vulnerable to concealed drinking water injury. common inspection solutions like Visible checks or Main sampling can skip issues until they develop into critical.
