Flat roofs are trusted, sensible, and stylish — Nonetheless they can be tough. in contrast to sloped roofs, in which leaks frequently surface rapidly, flat roof leaks can continue being concealed for months beneath layers of insulation and membranes. Water may possibly journey horizontally through the roofing procedure, showing up as stains far from its resource. by the point the condition will become noticeable, major inner hurt may have already got transpired.
This is when infrared roof scanning is available in. It’s The most Sophisticated, non-harmful ways to locate moisture and detect concealed leaks ahead of they escalate into high priced repairs. For Canadian residence homeowners addressing Severe weather, infrared technological know-how is now a sport-changer in flat roof servicing and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes warmth-sensing cameras to discover temperature discrepancies within the area of a roof. The fundamental theory is straightforward: soaked elements keep warmth differently than dry ones.
When the Sunlight warms a roof during the day, parts made up of trapped humidity soak up and hold heat for a longer period. right after sunset, since the roof cools, All those damp spots launch warmth far more slowly and gradually — creating visible “warm spots” on an infrared graphic.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks under membranes.
-
spots with saturated insulation.
-
Damaged or delaminated roofing materials.
-
Drainage challenges or trapped dampness in close proximity to seams.
This non-invasive approach allows for precise detection without the need of slicing or damaging the roofing process.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, particularly in business and multi-household buildings, are especially at risk of concealed drinking water hurt. common inspection solutions like visual checks or core sampling can miss challenges till they become intense. Infrared scanning, on the other hand, detects problems very long right before they’re noticeable.
Here’s why it’s Specifically vital for Canadian flat roofs:
one. concealed humidity Beneath the Surface
Flat roofs frequently use multiple levels — membrane, insulation, vapour barrier, and deck. A small puncture can allow for drinking water to spread amongst these levels. Infrared scans detect that moisture instantaneously, even when no noticeable leak exists.
2. security Against Freeze-Thaw Damage
In Canada’s chilly local climate, water trapped beneath the membrane can freeze and grow, triggering blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the structure.

action 2: Thermal Imaging Capture
specialists use handheld or drone-mounted infrared cameras to capture temperature patterns throughout the roof area. These products detect heat radiation and translate it into a colour-coded graphic — crimson or yellow locations suggest retained heat (probable dampness), whilst blue or purple locations exhibit cooler, dry sections.
move 3: knowledge Investigation
The captured images are analysed to determine irregular temperature zones. Just about every anomaly is cross-checked with on-website visual observations and in some cases moisture meters for affirmation.
move four: Detailed Report
an experienced report follows, like infrared photographs, marked difficulty places, dampness estimates, and repair service recommendations. setting up homeowners can then share this report with their roofing contractor to prepare specific repairs.
