Flat roofs are reputable, simple, and stylish — Nevertheless they will also be difficult. as opposed to sloped roofs, the place leaks often appear promptly, flat roof leaks can stay concealed for months beneath layers of insulation and membranes. h2o may perhaps vacation horizontally from the roofing technique, displaying up as stains significantly from its supply. By the time the issue becomes seen, significant interior problems may possibly already have transpired.
This is when infrared roof scanning is available in. It’s The most Sophisticated, non-harmful methods to Track down moisture and detect hidden leaks right before they escalate into costly repairs. For Canadian property owners coping with extreme climate, infrared technology is becoming a activity-changer in flat roof servicing and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) takes advantage of heat-sensing cameras to determine temperature variations around the surface of a roof. The essential principle is simple: wet resources keep warmth in another way than dry kinds.
once the Solar warms a roof during the day, spots containing trapped humidity take up and hold heat longer. following sunset, as being the roof cools, Those people damp spots launch heat extra slowly — making visible “hot places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
parts with saturated insulation.
-
harmed or delaminated roofing resources.
-
Drainage troubles or trapped humidity near seams.
This non-invasive strategy allows for precise detection devoid of chopping or damaging the roofing program.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, specifically in business and multi-residential buildings, are specifically liable to concealed water destruction. classic inspection solutions like Visible checks or core sampling can overlook issues until finally they come to be extreme. Infrared scanning, Conversely, detects difficulties long prior to they’re noticeable.
listed here’s why it’s Particularly significant for Canadian flat roofs:
1. Hidden dampness Beneath the floor
Flat roofs often use many layers — membrane, insulation, vapour barrier, and deck. A small puncture can allow water to unfold involving these levels. Infrared scans detect that humidity right away, even though no noticeable leak exists.
2. defense in opposition to Freeze-Thaw Damage
In Canada’s cold weather, h2o trapped under the membrane can freeze and extend, creating blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the composition.

phase 1: web-site planning
The inspection is usually scheduled after sunset or early early morning, once the temperature difference between wet and dry supplies is most seen. The roof should be clean, dry, and free of particles to avoid distorted readings.
phase two: Thermal Imaging Capture
Technicians use handheld or drone-mounted infrared cameras to seize temperature patterns through the roof floor. These equipment detect warmth radiation and translate it right into a colour-coded impression — pink or yellow areas show retained heat (possible moisture), even though blue or purple spots clearly show cooler, dry sections.
action three: info Assessment
The captured pictures are analysed to identify irregular temperature zones. Every anomaly is cross-checked with on-site visual observations and often moisture meters for confirmation.
phase 4: thorough Report
an experienced report follows, which include infrared visuals, marked issue locations, humidity estimates, and restore suggestions. Building entrepreneurs can then share this report with their roofing contractor to strategy focused repairs.
