Flat roofs are reliable, sensible, and stylish — Nonetheless they can also be tricky. Unlike sloped roofs, wherever leaks usually show up rapidly, flat roof leaks can keep on being concealed for months beneath layers of insulation and membranes. h2o could journey horizontally throughout the roofing system, displaying up as stains significantly from its resource. by the point the trouble results in being obvious, considerable inner destruction may perhaps already have occurred.
This is when infrared roof scanning comes in. It’s Probably the most Innovative, non-damaging methods to Track down humidity and detect hidden leaks before they escalate into high priced repairs. For Canadian assets homeowners managing Intense weather conditions, infrared know-how is now a match-changer in flat roof upkeep and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) employs warmth-sensing cameras to establish temperature variations on the floor of a roof. The basic theory is simple: soaked resources retain heat in another way than dry types.
When the Sunlight warms a roof during the day, locations containing trapped dampness take up and maintain warmth longer. After sunset, as the roof cools, those moist spots release warmth additional slowly — creating visible “sizzling spots” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks underneath membranes.
-
regions with saturated insulation.
-
Damaged or delaminated roofing resources.
-
Drainage challenges or trapped humidity around seams.
This non-invasive tactic permits accurate detection devoid of reducing or harming the roofing program.
Why Infrared Scanning Is Essential for Flat Roofs

Infrared scanning, Conversely, detects difficulties prolonged in advance of they’re visible.
in this article’s why it’s Particularly essential for Canadian flat roofs:
one. Hidden Moisture Beneath the Surface
Flat roofs frequently use multiple levels — membrane, insulation, vapour barrier, and deck. a little puncture can permit drinking water to spread between these levels. Infrared scans detect that humidity instantaneously, even when no obvious leak exists.
two. safety towards Freeze-Thaw problems
In Canada’s cold local weather, water trapped underneath the membrane can freeze and broaden, causing blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the construction.
three. decreased Repair expenses
Infrared know-how identifies the actual area and dimensions of destroyed places, so contractors only repair service what’s necessary as an alternative to changing the entire roof.
4. prolonged Roof Lifespan
By catching leaks early, infrared scans protect against extensive-time period deterioration, assisting roofs very last closer to their complete envisioned lifespan — frequently twenty five to 30 yrs.
5. assist for guarantee and insurance policies promises
quite a few manufacturers and insurers now recognise thermal imaging experiences as valid documentation for preventive upkeep or leak supply identification.
How Infrared Roof Scans perform
An infrared scan follows a systematic procedure to ensure precision.
phase 1: website planning
The inspection is normally scheduled soon after sunset or early early morning, when the temperature distinction between moist and dry components is most visible. The roof need to be cleanse, dry, and free of particles to stay away from distorted readings.
phase two: Thermal Imaging Capture
professionals use handheld or drone-mounted infrared cameras to capture temperature designs throughout the roof area. These gadgets detect heat radiation and translate it right into a colour-coded image — crimson or yellow spots reveal retained warmth (attainable dampness), whilst blue or purple spots exhibit cooler, dry sections.
Step 3: facts Investigation
The captured photographs are analysed to detect irregular temperature zones. Every single anomaly is cross-checked with on-site Visible observations and occasionally humidity meters for confirmation.
action 4: comprehensive Report
knowledgeable report follows, including infrared photos, marked problem spots, moisture estimates, and repair service suggestions. constructing proprietors can then share this report with their roofing contractor to approach focused repairs.
suitable ailments for Accurate Scans
To achieve reliable benefits, selected environmental and Actual physical problems needs to be satisfied — significantly in Canada’s various local climate:
