Flat roofs are trusted, functional, and stylish — Nevertheless they will also be difficult. contrary to sloped roofs, the place leaks typically appear swiftly, flat roof leaks can stay concealed for months beneath levels of insulation and membranes. Water may possibly journey horizontally from the roofing procedure, demonstrating up as stains far from its supply. By the time the challenge gets noticeable, considerable interior damage may perhaps have already got transpired.
This is when infrared roof scanning comes in. It’s One of the more Highly developed, non-harmful strategies to Track down dampness and detect hidden leaks right before they escalate into costly repairs. For Canadian property proprietors managing Severe temperature, infrared technologies has become a game-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) takes advantage of heat-sensing cameras to recognize temperature distinctions around the floor of a roof. The fundamental principle is simple: damp resources keep warmth otherwise than dry kinds.
if the Solar warms a roof during the day, places that contains trapped moisture soak up and keep warmth lengthier. just after sunset, as being the roof cools, Those people moist places launch warmth far more little by little — generating seen “incredibly hot places” on an infrared impression.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks beneath membranes.
-
regions with saturated insulation.
-
harmed or delaminated roofing supplies.
-
Drainage troubles or trapped dampness in close proximity to seams.
This non-invasive method allows for exact detection with no reducing or damaging the roofing system.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in professional and multi-household buildings, are notably susceptible to hidden water hurt. conventional inspection procedures like visual checks or Main sampling can pass up difficulties until eventually they turn into critical. Infrared scanning, Alternatively, detects concerns prolonged ahead of they’re noticeable.
right here’s why it’s especially essential for Canadian flat roofs:
one. Hidden dampness Beneath the floor
Flat roofs normally use several layers — membrane, insulation, vapour barrier, and deck. a little puncture can let drinking water to distribute in between these layers. Infrared scans detect that humidity promptly, even when no visible leak exists.
two. defense towards Freeze-Thaw harm
In Canada’s chilly weather, h2o trapped beneath the membrane can freeze and expand, leading to blisters, cracks, and delamination. Early detection prevents this cycle from weakening the structure.

move 1: web site preparing
The inspection is normally scheduled right after sunset or early early morning, once the temperature distinction between soaked and dry supplies is most seen. The roof need to be clean up, dry, and freed from particles to prevent distorted readings.
move 2: Thermal Imaging seize
Technicians use handheld or drone-mounted infrared cameras to capture temperature styles across the roof surface area. These gadgets detect heat radiation and translate it into a colour-coded graphic — red or yellow regions reveal retained warmth (possible dampness), whilst blue or purple regions exhibit cooler, dry sections.
move three: facts Assessment
The captured images are analysed to determine irregular temperature zones. Just about every anomaly is cross-checked with on-site Visible observations and in some cases humidity meters for confirmation.
stage four: in depth Report
an experienced report follows, which includes infrared photos, marked challenge parts, humidity estimates, and fix tips. constructing homeowners can then share this report with their roofing contractor to prepare focused repairs.
