Flat roofs are reputable, sensible, and trendy — However they can even be tough. not like sloped roofs, exactly where leaks frequently seem promptly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. Water may possibly journey horizontally with the roofing method, showing up as stains much from its source. by the point the problem gets to be visible, substantial interior harm may possibly have already got occurred.
This is where infrared roof scanning is available in. It’s Just about the most State-of-the-art, non-destructive ways to locate moisture and detect concealed leaks ahead of they escalate into highly-priced repairs. For Canadian house house owners managing Intense weather conditions, infrared know-how is becoming a video game-changer in flat roof upkeep and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) works by using warmth-sensing cameras to determine temperature discrepancies within the surface area of a roof. The fundamental theory is straightforward: soaked materials keep warmth in different ways than dry types.
in the event the Solar warms a roof throughout the day, parts made up of trapped moisture take in and maintain warmth extended. right after sunset, since the roof cools, All those soaked spots release heat a lot more slowly but surely — producing noticeable “scorching places” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks underneath membranes.
-
locations with saturated insulation.
-
harmed or delaminated roofing elements.
-
Drainage challenges or trapped dampness in close proximity to seams.
This non-invasive tactic permits correct detection without the need of chopping or detrimental the roofing program.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in commercial and multi-household structures, are especially liable to concealed water problems. classic inspection strategies like visual checks or core sampling can miss troubles until they come to be severe. Infrared scanning, Then again, detects troubles very long just before they’re visible.
right here’s why it’s Specifically significant for Canadian flat roofs:
one. concealed humidity Beneath the area
Flat roofs generally use many levels — membrane, insulation, vapour barrier, and deck. A small puncture can permit drinking water to distribute concerning these levels. Infrared scans detect that moisture right away, even though no seen leak exists.
two. security Against Freeze-Thaw injury
In Canada’s chilly weather, h2o trapped underneath the membrane can freeze and grow, causing blisters, cracks, and delamination. Early detection prevents this cycle from weakening the construction.
three. diminished restore Costs

The inspection is generally scheduled right after sunset or early early morning, in the event the temperature difference between damp and dry resources is most noticeable. The roof must be clean, dry, and freed from particles to stay away from distorted readings.
phase 2: Thermal Imaging seize
Technicians use handheld or drone-mounted infrared cameras to capture temperature patterns throughout the roof floor. These devices detect heat radiation and translate it into a colour-coded image — red or yellow places reveal retained heat (achievable dampness), when blue or purple places demonstrate cooler, dry sections.
stage 3: details Investigation
The captured visuals are analysed to recognize irregular temperature zones. Each individual anomaly is cross-checked with on-site visual observations and occasionally moisture meters for affirmation.
action four: in depth Report
a specialist report follows, like infrared photographs, marked issue places, humidity estimates, and repair service suggestions. making proprietors can then share this report with their roofing contractor to program specific repairs.
perfect Conditions for Accurate Scans
