Flat roofs are dependable, useful, and classy — Nevertheless they can be tricky. in contrast to sloped roofs, where by leaks normally surface speedily, flat roof leaks can remain hidden for months beneath layers of insulation and membranes. drinking water might journey horizontally throughout the roofing method, displaying up as stains much spring and fall roof inspections from its resource. By the time the issue turns into noticeable, significant internal hurt may perhaps already have occurred.
This is when infrared roof scanning comes in. It’s one of the most Superior, non-destructive strategies to Find dampness and detect concealed leaks before they escalate into highly-priced repairs. For Canadian property house owners handling extreme climate, infrared technological know-how is now a sport-changer in flat roof servicing and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) employs heat-sensing cameras to identify temperature discrepancies over the floor of the roof. The basic theory is straightforward: wet components keep warmth in another way than dry kinds.
in the event the Sunshine warms a roof throughout the day, locations that contains trapped humidity soak up and keep heat longer. following sunset, given that the roof cools, Those people moist places launch heat additional slowly but surely — making seen “warm places” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
places with saturated insulation.
-
ruined or delaminated roofing resources.
-
Drainage problems or trapped moisture in close proximity to seams.
This non-invasive strategy permits accurate detection without having cutting or damaging the roofing procedure.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in business and multi-residential structures, are specifically vulnerable to hidden water harm. conventional inspection methods like visual checks or core sampling can miss troubles until eventually they become extreme. Infrared scanning, Alternatively, detects concerns long before they’re seen.
listed here’s why it’s especially crucial for Canadian flat roofs:

stage 2: Thermal Imaging Capture
Technicians use handheld or drone-mounted infrared cameras to seize temperature patterns throughout the roof surface area. These equipment detect warmth radiation and translate it right into a colour-coded picture — crimson or yellow parts reveal retained heat (attainable humidity), when blue or purple places display cooler, dry sections.
Step 3: info Investigation
The captured photographs are analysed to recognize irregular temperature zones. Each anomaly is cross-checked with on-site visual observations and sometimes dampness meters for confirmation.
stage 4: in depth Report
a specialist report follows, such as infrared illustrations or photos, marked issue places, moisture estimates, and repair suggestions. creating owners can then share this report with their roofing contractor to prepare targeted repairs.
