Flat roofs are reliable, practical, and classy — Nevertheless they can even be tough. not like sloped roofs, exactly where leaks normally appear immediately, flat roof leaks can continue to be hidden for months beneath layers of insulation and membranes. h2o may perhaps travel horizontally in the roofing system, displaying up as stains much from its resource. by the point the situation will become obvious, significant interior problems may possibly already have occurred.
This is where infrared roof scanning comes in. It’s One of the more Highly developed, non-damaging strategies to locate dampness and detect concealed leaks right before they escalate into high-priced repairs. For Canadian house house owners working with Severe weather, infrared technologies happens to be a sport-changer in flat roof upkeep and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) takes advantage of warmth-sensing cameras to discover temperature differences on the surface of the roof. The fundamental principle is easy: wet components keep warmth in different ways than dry kinds.
once the sun warms a roof during the day, regions that contains trapped humidity take up and keep heat for a longer period. just after sunset, because the roof cools, All those damp places launch heat much more slowly but surely — creating obvious “hot spots” on an infrared image.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
spots with saturated insulation.
-
destroyed or delaminated roofing products.
-
Drainage concerns or trapped humidity around seams.
This non-invasive method allows for exact detection with no slicing or harming the roofing system.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, specifically in commercial and multi-household properties, are notably vulnerable to concealed water problems. Traditional inspection techniques like Visible checks or Main sampling can overlook complications till they turn into serious. Infrared scanning, Conversely, detects challenges extended just before they’re visible.
Here’s why it’s especially essential for Canadian flat roofs:
one. concealed dampness Beneath the floor
Flat roofs often use multiple levels — membrane, insulation, vapour barrier, and deck. a little puncture can let water to unfold involving these levels. Infrared scans detect that dampness instantly, even though no visible leak exists.
two. defense towards Freeze-Thaw hurt
In Canada’s chilly climate, water trapped beneath the membrane can here freeze and develop, triggering blisters, cracks, and delamination. Early detection prevents this cycle from weakening the framework.
three. decreased Repair expenditures
Infrared engineering identifies the precise spot and dimensions of destroyed spots, so contractors only restore what’s necessary in lieu of changing the entire roof.
four. Extended Roof Lifespan
By catching leaks early, infrared scans avoid long-expression deterioration, serving to roofs last nearer for their whole expected lifespan — usually 25 to 30 decades.
five. aid for Warranty and Insurance promises
Many producers and insurers now recognise thermal imaging experiences as valid documentation for preventive maintenance or leak resource identification.
How Infrared Roof Scans perform

move 2: Thermal Imaging Capture
professionals use handheld or drone-mounted infrared cameras to capture temperature styles through the roof surface. These equipment detect heat radiation and translate it right into a colour-coded impression — purple or yellow areas show retained warmth (doable humidity), while blue or purple regions clearly show cooler, dry sections.
Step 3: facts Examination
The captured pictures are analysed to discover irregular temperature zones. Just about every anomaly is cross-checked with on-site visual observations and often humidity meters for affirmation.
move 4: thorough Report
a specialist report follows, such as infrared images, marked issue locations, moisture estimates, and fix tips. creating house owners can then share this report with their roofing contractor to approach focused repairs.
perfect Conditions for exact Scans
