Flat roofs are dependable, functional, and classy — However they can be challenging. as opposed to sloped roofs, where leaks frequently appear immediately, flat roof leaks can stay hidden for months beneath layers of insulation and membranes. h2o may perhaps vacation horizontally throughout the roofing process, displaying up as stains considerably from its source. By the time the trouble turns into obvious, substantial inner harm might already have occurred.
This is where infrared roof scanning comes in. It’s Among the most Highly developed, non-destructive strategies to locate moisture and detect hidden leaks before they escalate into costly repairs. For Canadian home owners working with Serious climate, infrared technology is becoming a game-changer in flat roof maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) utilizes warmth-sensing cameras to identify temperature distinctions about the surface of a roof. The essential theory is easy: damp components retain heat in a different way than dry kinds.
once the Sunlight warms a roof during the day, regions made up of trapped dampness absorb and maintain heat extended. just after sunset, because the roof cools, These wet places release heat extra slowly and gradually — producing noticeable “scorching places” on an infrared picture.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
Areas with saturated insulation.
-
destroyed or delaminated roofing supplies.
-
Drainage issues or trapped dampness in close proximity to seams.
This non-invasive solution permits precise detection with out slicing or harming the roofing method.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, especially in commercial and multi-household buildings, are particularly liable to concealed drinking water destruction. classic inspection procedures like visual checks or Main sampling can miss out on difficulties right up until they turn out to be critical. Infrared scanning, Then again, detects difficulties very long before they’re visible.
listed here’s why it’s especially significant for Canadian flat roofs:
one. Hidden dampness Beneath the floor
Flat roofs typically use various levels — membrane, insulation, vapour barrier, and deck. a little puncture can allow drinking water to spread in between these levels. Infrared scans detect that moisture instantaneously, regardless if no obvious leak exists.
2. safety from Freeze-Thaw harm
In Canada’s chilly local weather, water trapped underneath the membrane can freeze and develop, causing blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the structure.

The inspection is generally scheduled immediately after sunset or early morning, if the temperature distinction between damp and dry materials is most noticeable. The roof needs to be thoroughly clean, dry, and freed from particles to stop distorted readings.
stage 2: Thermal Imaging Capture
professionals use handheld or drone-mounted infrared cameras to capture temperature designs throughout the roof floor. These devices detect warmth radiation and translate it right into a colour-coded graphic — red or yellow areas indicate retained heat (probable dampness), though blue click here or purple areas clearly show cooler, dry sections.
phase three: knowledge Analysis
The captured pictures are analysed to establish irregular temperature zones. Each individual anomaly is cross-checked with on-web site visual observations and occasionally humidity meters for confirmation.
stage 4: comprehensive Report
a specialist report follows, which includes infrared pictures, marked trouble parts, moisture estimates, and maintenance tips. constructing house owners can then share this report with their roofing contractor to strategy qualified repairs.
