Flat roofs are trustworthy, simple, and trendy — Nonetheless they will also be tough. not like sloped roofs, the place leaks generally show up rapidly, flat roof leaks can continue being concealed for months beneath levels of insulation and membranes. drinking water could vacation horizontally in the roofing program, exhibiting up as stains considerably from its supply. By the time the issue will become obvious, sizeable internal harm could already have happened.
This is where infrared roof scanning comes in. It’s Among the most Superior, non-destructive methods to locate moisture and detect concealed leaks ahead of they escalate into expensive repairs. For Canadian residence house owners coping with extreme weather, infrared technological know-how happens to be a match-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) uses heat-sensing cameras to establish temperature variances around the surface of the roof. The fundamental theory is simple: wet resources retain warmth in different ways than dry ones.
once the Sunshine warms a roof during the day, areas made up of trapped humidity take up and maintain warmth for a longer period. right after sunset, given that the roof cools, Those people soaked spots launch warmth additional gradually — producing seen “very hot places” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks beneath membranes.
-
places with saturated insulation.
-
destroyed or delaminated roofing components.

phase two: Thermal Imaging Capture
experts use handheld or drone-mounted infrared cameras to seize temperature patterns across the roof surface area. These products detect warmth radiation and translate it into a colour-coded graphic — red or yellow regions indicate retained warmth (feasible dampness), even though blue or purple places present cooler, dry sections.
phase 3: info Investigation
The captured illustrations or photos are analysed to recognize irregular temperature zones. Every single anomaly is cross-checked with on-website Visible observations and sometimes humidity meters for affirmation.
stage four: thorough Report
a specialist report follows, which includes infrared images, marked problem spots, moisture estimates, and repair tips. Building house owners can then share this report with their roofing contractor to strategy focused repairs.
