Flat roofs are reliable, functional, and classy — However they can even be difficult. not like sloped roofs, where leaks often appear speedily, flat roof leaks can continue being hidden for months beneath layers of insulation and membranes. drinking water may possibly journey horizontally with the roofing process, showing up as stains far from its supply. By the time the trouble becomes visible, significant inside problems may well already have occurred.
This is where infrared roof scanning is available in. It’s Just about the most Superior, non-destructive methods to Identify moisture and detect concealed leaks right before they escalate into high-priced repairs. For Canadian assets proprietors dealing with Excessive weather, infrared technological know-how is now a game-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) works by using heat-sensing cameras to establish temperature dissimilarities on the surface area of a roof. The basic theory is simple: soaked elements keep heat in a different way than dry kinds.
if the Solar warms a roof during the day, regions containing trapped moisture absorb and hold heat extended. following sunset, as the roof cools, those soaked spots launch warmth more gradually — building visible “scorching places” on an infrared impression.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
spots with saturated insulation.
-
harmed or delaminated roofing components.
-
Drainage issues or trapped humidity in the vicinity of seams.
This non-invasive tactic allows for accurate detection without having slicing or damaging the roofing process.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in business and multi-household properties, are particularly prone to concealed drinking water problems. regular inspection approaches like visual checks or core sampling can skip challenges until eventually they grow to be critical. Infrared scanning, However, detects troubles lengthy just before they’re noticeable.
below’s why it’s Primarily significant for Canadian flat roofs:
one. concealed Moisture Beneath the Surface
Flat roofs typically use various layers — membrane, insulation, vapour barrier, and deck. A small puncture can allow for h2o to unfold concerning these layers. Infrared scans detect that moisture quickly, regardless if no visible leak exists.
2. Protection towards Freeze-Thaw problems
In Canada’s chilly weather, drinking water trapped under the membrane can freeze and increase, resulting in blisters, cracks, and delamination. Early detection prevents this cycle from weakening the structure.

phase 2: Thermal Imaging Capture
professionals use handheld or drone-mounted infrared cameras to seize temperature styles through the roof surface. These gadgets detect heat radiation and translate it right into a colour-coded graphic — crimson or yellow locations show retained heat (possible dampness), when blue or purple spots demonstrate cooler, dry sections.
Step 3: info Assessment
The captured photos are analysed to detect irregular temperature zones. Every anomaly is cross-checked with on-web page Visible observations and from time to time dampness meters for affirmation.
stage 4: comprehensive Report
an experienced report follows, including infrared illustrations or photos, marked challenge parts, dampness estimates, and mend suggestions. making proprietors can then share this report with their roofing contractor to prepare qualified repairs.
excellent Conditions for Accurate Scans
