Flat roofs are reliable, realistic, and classy — Nevertheless they can be tough. not like sloped roofs, the place leaks frequently seem immediately, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may well vacation horizontally through the roofing technique, demonstrating up as stains significantly from its supply. by the point the situation results in being visible, major interior injury might already have occurred.
This is when infrared roof scanning comes in. It’s Probably the most advanced, non-destructive ways to locate humidity and detect concealed leaks in advance of they escalate into high-priced repairs. For Canadian house homeowners coping with extreme temperature, infrared know-how has become a sport-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) takes advantage of warmth-sensing cameras to recognize temperature discrepancies around the area of the roof. The fundamental theory is easy: moist materials retain heat differently than dry ones.
if the sun warms a roof throughout the day, spots made up of trapped humidity take in and hold heat longer. following sunset, since the roof cools, People wet places launch warmth extra bit by bit — building visible “incredibly hot places” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks under membranes.
-
parts with saturated insulation.
-
destroyed or delaminated roofing elements.
-
Drainage challenges or trapped dampness close to seams.
This non-invasive strategy permits exact detection without reducing or damaging the roofing technique.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, particularly in commercial and multi-residential buildings, are specifically prone to concealed h2o injury. conventional inspection procedures like visual checks or Main sampling can skip issues until they turn out to be intense.

action two: Thermal Imaging Capture
Technicians use handheld or drone-mounted infrared cameras to capture temperature patterns across the roof floor. These products detect warmth radiation and translate it right into a colour-coded impression — purple or yellow locations indicate retained warmth (possible moisture), though blue or purple areas display cooler, dry sections.
stage 3: Data Analysis
The captured photographs are analysed to recognize irregular temperature zones. Every anomaly is cross-checked with on-website visual observations and in some cases humidity meters for affirmation.
move 4: specific Report
an experienced report follows, such as infrared photos, marked problem parts, humidity estimates, and mend recommendations. Building homeowners can then share this report with their roofing contractor to strategy qualified repairs.
