Flat roofs are dependable, sensible, and trendy — However they can also be tricky. not like sloped roofs, where leaks normally look swiftly, flat roof leaks can keep on being hidden for months beneath layers of insulation and membranes. h2o may possibly journey horizontally in the roofing program, displaying up as stains far from its source. By the time the challenge results in being obvious, important inner injury could have already got occurred.
This is when infrared roof scanning is available in. It’s Just about the most advanced, non-damaging strategies to locate humidity and detect concealed leaks ahead of they escalate into costly repairs. For Canadian assets entrepreneurs managing Extraordinary weather conditions, infrared technological know-how is now a recreation-changer in flat roof servicing and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) uses warmth-sensing cameras to determine temperature variances on the floor of a roof. The fundamental principle is easy: soaked products retain warmth in different ways than dry kinds.
in the event the Solar warms a roof during the day, locations made up of trapped moisture take up and keep heat lengthier. soon after sunset, as being the roof cools, those wet spots release heat additional little by little — developing seen “very hot spots” on an infrared impression.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
Areas with saturated insulation.
-
ruined or delaminated roofing elements.
-
Drainage concerns or trapped humidity in the vicinity of seams.
This non-invasive approach allows for exact detection devoid of cutting or harmful the roofing method.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, specifically in professional and multi-household structures, are specially prone to concealed drinking water harm. common inspection procedures like visual checks or core sampling can miss troubles until finally they turn into significant.

The inspection is normally scheduled soon after sunset or early early morning, once the temperature distinction between moist and dry products is most obvious. The roof must be cleanse, dry, and freed from debris to prevent distorted readings.
move two: Thermal Imaging seize
experts use handheld or drone-mounted infrared cameras to capture temperature styles across the roof floor. These devices detect heat radiation and translate it right into a colour-coded impression — purple or yellow regions suggest retained warmth (probable humidity), whilst blue or purple locations demonstrate cooler, dry sections.
move 3: information Assessment
The captured images are analysed to establish irregular temperature zones. Each anomaly is cross-checked with on-web site visual observations and at times moisture meters for confirmation.
phase four: comprehensive Report
an expert report follows, together with infrared illustrations or photos, marked issue regions, dampness estimates, and fix suggestions. Building owners can then share this report with their roofing contractor to program professional roofing maintenance toronto focused repairs.
