Flat roofs are trustworthy, simple, and trendy — Nonetheless they can be difficult. Unlike sloped roofs, the place leaks frequently seem rapidly, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may possibly journey horizontally from the roofing procedure, demonstrating up as stains considerably from its supply. By the time the problem becomes visible, sizeable inner injury may possibly already have transpired.
This is where infrared roof scanning is available in. It’s Probably the most Highly developed, non-harmful methods to locate moisture and detect hidden leaks ahead of they escalate into costly repairs. For Canadian home homeowners handling Extraordinary weather conditions, infrared engineering is now a match-changer in flat roof maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) employs warmth-sensing cameras to discover temperature differences around the floor of the roof. The essential basic principle is straightforward: moist products keep warmth differently than dry kinds.
When the Sunlight warms a roof during the day, regions containing trapped humidity take in and hold warmth longer. soon after sunset, as the roof cools, These damp places release warmth much more slowly and gradually — producing noticeable “very hot places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks below membranes.
-
places with saturated insulation.
-
broken or delaminated roofing resources.
-
Drainage issues or trapped moisture near seams.
This non-invasive technique permits precise detection without having cutting or harming the roofing procedure.
Why Infrared Scanning Is Essential for Flat Roofs

move two: Thermal Imaging seize
experts use handheld or drone-mounted infrared cameras to seize temperature patterns throughout the roof area. These devices detect heat radiation and translate it into a colour-coded image — crimson or yellow areas indicate retained heat (attainable dampness), although blue or purple places exhibit cooler, dry sections.
move three: information Evaluation
The captured photos are analysed to identify irregular temperature zones. Every single anomaly is cross-checked with on-web site Visible observations and often dampness meters for confirmation.
stage four: in depth Report
knowledgeable report follows, which includes infrared illustrations or photos, marked issue spots, moisture estimates, and mend recommendations. making homeowners can then share this report with their roofing contractor to strategy focused repairs.
best circumstances for exact Scans
to attain reliable outcomes, specified environmental and Bodily ailments should be satisfied — specially in Canada’s assorted climate:
