Flat roofs are trusted, simple, and trendy — Nonetheless they will also be challenging. contrary to sloped roofs, where leaks generally show up quickly, flat roof leaks can remain hidden for months beneath levels of insulation and membranes. drinking water may perhaps travel horizontally from the roofing method, showing up as stains far from its resource. By the time the situation turns into obvious, major inner hurt may well have already got occurred.
This is when infrared roof scanning is available in. It’s One of the more Highly developed, non-harmful ways to Identify humidity and detect concealed leaks right before they escalate into pricey repairs. For Canadian property entrepreneurs handling Intense climate, infrared technologies has become a game-changer in flat roof maintenance and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) uses heat-sensing cameras to establish temperature distinctions over the floor of a roof. The basic theory is straightforward: moist resources retain heat differently than dry kinds.
When the Solar warms a roof throughout the day, locations containing trapped moisture take up and maintain warmth longer. following sunset, as the roof cools, Those people wet spots launch warmth a lot more little by little — producing seen “sizzling places” on an infrared image.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
spots with saturated insulation.
-
ruined or delaminated roofing products.
-
Drainage issues or trapped dampness close to seams.
This non-invasive technique allows for exact detection devoid of cutting or harming the roofing program.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, particularly in commercial and multi-household properties, are notably prone to hidden h2o problems. classic inspection techniques like Visible checks or Main sampling can miss out on issues till they develop into critical. Infrared scanning, On the flip side, detects challenges extensive in advance of they’re seen.
right here’s why it’s In particular vital for Canadian flat roofs:
1. Hidden Moisture Beneath the floor
Flat roofs normally use a number of levels — membrane, insulation, vapour barrier, and deck. a little puncture can permit drinking water to spread amongst these layers. Infrared scans detect that moisture instantaneously, regardless if no seen leak exists.
two. security in opposition to Freeze-Thaw Damage
In Canada’s chilly weather, water trapped under the membrane can freeze and expand, causing blisters, cracks, and delamination. Early detection stops this cycle from weakening the structure.
three. Reduced restore expenses
Infrared technology identifies the actual area and measurement of broken areas, so contractors only fix what’s vital as an alternative to replacing all the roof.
four. prolonged Roof Lifespan
By catching leaks early, infrared scans protect against extensive-term deterioration, serving to roofs previous nearer for their full anticipated lifespan — generally 25 to 30 decades.
five. aid for Warranty and coverage promises
several brands and insurers now recognise thermal imaging stories check here as valid documentation for preventive upkeep or leak resource identification.

stage two: Thermal Imaging seize
specialists use handheld or drone-mounted infrared cameras to seize temperature patterns through the roof surface. These equipment detect warmth radiation and translate it right into a colour-coded image — red or yellow spots indicate retained heat (doable humidity), while blue or purple regions demonstrate cooler, dry sections.
action 3: knowledge Examination
The captured photos are analysed to discover irregular temperature zones. Each individual anomaly is cross-checked with on-web-site visual observations and occasionally dampness meters for confirmation.
action 4: comprehensive Report
an experienced report follows, together with infrared photographs, marked challenge parts, humidity estimates, and maintenance tips. making proprietors can then share this report with their roofing contractor to system qualified repairs.
