Flat roofs are dependable, useful, and stylish — Nonetheless they can even be tricky. not like sloped roofs, in which leaks typically seem speedily, flat roof leaks can continue being concealed for months beneath levels of insulation and membranes. drinking water may perhaps travel horizontally from the roofing system, demonstrating up as stains far from its supply. by the point the issue results in being noticeable, considerable internal injury may have already got transpired.
This is where infrared roof scanning is available in. It’s Among the most State-of-the-art, non-destructive strategies to Track down dampness and detect hidden leaks before they escalate into highly-priced repairs. For Canadian home proprietors coping with extreme weather conditions, infrared technology has grown to be a game-changer in flat roof servicing and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes warmth-sensing cameras to discover temperature differences within the surface area of the roof. The basic principle is straightforward: soaked resources keep heat in another way than dry kinds.
once the sun warms a roof during the day, parts made up of trapped humidity take in and maintain warmth more time. soon after sunset, because the roof cools, Individuals moist spots release warmth additional little by little — building seen “sizzling spots” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks below membranes.
-
regions with saturated insulation.
-
ruined or delaminated roofing components.
-
Drainage issues or trapped dampness in the vicinity of seams.
This non-invasive approach allows for correct detection with no cutting or damaging the roofing procedure.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in industrial and multi-residential structures, are notably vulnerable to hidden water hurt. standard inspection strategies like Visible checks or Main sampling can overlook complications until finally they develop into critical.

action 2: Thermal Imaging Capture
specialists use handheld or drone-mounted infrared cameras to capture temperature patterns over the roof floor. These products detect heat radiation and translate it right into a colour-coded impression — crimson or yellow locations reveal retained heat (probable humidity), although blue or purple areas exhibit cooler, dry sections.
action three: information Evaluation
The captured visuals are analysed to recognize irregular temperature zones. Each anomaly is cross-checked with on-web site visual observations and occasionally moisture meters for confirmation.
phase 4: comprehensive Report
a specialist report follows, including infrared images, marked problem parts, dampness estimates, and restore tips. setting up homeowners can then share this report with their roofing contractor to plan specific repairs.
