Flat roofs are dependable, practical, and stylish — Nevertheless they will also be tricky. contrary to sloped roofs, the place leaks usually seem immediately, flat roof leaks can keep on being concealed for months beneath levels of insulation and membranes. Water may possibly vacation horizontally through the roofing process, displaying up as stains significantly from its supply. by the point the situation gets seen, significant internal injury could already have transpired.
This is where infrared roof scanning is available in. It’s The most advanced, non-damaging ways to Track down dampness and detect concealed leaks ahead of they escalate into high priced repairs. For Canadian residence owners coping with Intense weather, infrared engineering has become a game-changer in flat roof maintenance and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) works by using heat-sensing cameras to establish temperature discrepancies about the surface of a roof. The essential principle is easy: damp elements retain heat differently than dry types.
once the Sunshine warms a roof during the day, regions made up of trapped dampness soak up and maintain warmth for a longer time. just after sunset, because the roof cools, All those moist places release heat additional slowly — building noticeable “sizzling spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
locations with saturated insulation.
-
destroyed or delaminated roofing components.
-
Drainage challenges or trapped humidity in the vicinity of seams.
This non-invasive solution permits correct detection without having slicing or detrimental the roofing procedure.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, especially in industrial and multi-household properties, are specially prone to hidden water hurt. classic inspection approaches like Visible checks or Main sampling can skip complications until finally they become extreme. Infrared scanning, Conversely, detects difficulties very long in advance of they’re seen.
listed here’s why it’s especially important for Canadian flat roofs:
one. concealed dampness Beneath the area
Flat roofs often use several layers — membrane, insulation, vapour barrier, and deck. A small puncture can allow for drinking water to spread concerning these layers. Infrared scans detect that moisture promptly, even when no noticeable leak exists.
2. safety in opposition to Freeze-Thaw destruction
In Canada’s cold weather, drinking water trapped underneath the membrane can freeze and expand, causing blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the structure.

phase 2: Thermal Imaging seize
specialists use handheld or drone-mounted infrared cameras to capture temperature patterns through the roof area. These products detect heat radiation and translate it right into a colour-coded graphic — crimson or yellow regions point out retained heat (doable dampness), though blue or purple areas clearly show cooler, dry sections.
Step three: details Examination
The captured photographs are analysed to determine irregular temperature zones. Each individual anomaly is cross-checked with on-website visual observations and in some cases humidity meters for affirmation.
Step 4: in-depth Report
an experienced report follows, which include infrared pictures, marked difficulty locations, dampness estimates, and maintenance tips. Building homeowners can then share this report with their roofing contractor to prepare qualified repairs.
