Flat roofs are dependable, realistic, and stylish — Nonetheless they may also be difficult. not like sloped roofs, where by leaks frequently appear speedily, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. Water may possibly vacation horizontally in the roofing procedure, showing up as stains far from its source. By the time the condition gets seen, substantial internal injury may have already got transpired.
This is when infrared roof scanning is available in. It’s Probably the most Sophisticated, non-destructive ways to locate dampness and detect hidden leaks before they escalate into high-priced repairs. For Canadian property homeowners handling Serious weather, infrared know-how happens to be a recreation-changer in flat roof maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) takes advantage of heat-sensing cameras to discover temperature distinctions over the surface area of the roof. The essential theory is straightforward: wet resources retain warmth differently than dry types.
if the Solar warms a roof throughout the day, regions made up of trapped humidity take up and maintain heat more time. following sunset, as the roof cools, Individuals soaked places launch heat extra slowly but surely — creating obvious “hot spots” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
Areas with saturated insulation.
-
broken or delaminated roofing materials.
-
Drainage troubles or trapped humidity around seams.
This non-invasive method allows for exact detection with out slicing or harming the roofing process.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, especially in business and multi-household buildings, are significantly vulnerable to hidden h2o damage. conventional inspection strategies like visual checks or Main sampling can overlook troubles until they turn out to be serious. Infrared scanning, However, detects challenges lengthy in advance of they’re visible.
below’s why it’s especially crucial for Canadian flat roofs:
one. concealed humidity Beneath the floor
Flat roofs often use multiple layers — membrane, insulation, vapour barrier, and deck. a little puncture can make it possible for water to spread amongst these layers. Infrared scans detect that moisture promptly, even when no seen leak exists.
2. Protection Against Freeze-Thaw problems
In Canada’s cold weather, h2o trapped underneath the membrane can freeze and expand, producing blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the composition.

stage two: Thermal Imaging seize
Technicians use handheld or drone-mounted infrared cameras to capture temperature designs over the roof surface. These devices detect warmth radiation and translate it right into a colour-coded picture — pink or yellow areas indicate retained heat (feasible moisture), although blue or purple regions show cooler, dry sections.
stage 3: information Examination
The captured pictures are analysed to determine irregular temperature zones. Every single anomaly is cross-checked with on-web-site visual observations and from time to time dampness meters for confirmation.
action four: in-depth Report
an experienced report follows, like infrared images, marked trouble locations, dampness estimates, flat roof cost per square foot toronto and restore tips. constructing homeowners can then share this report with their roofing contractor to system targeted repairs.
