Flat roofs are reputable, sensible, and stylish — Nonetheless they may also be difficult. in contrast to sloped roofs, in which leaks normally show up swiftly, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may possibly travel horizontally from the roofing system, demonstrating up as stains far from its source. By the time the condition gets seen, sizeable inside injury may have already got transpired.
This is where infrared roof scanning is available in. It’s The most Superior, non-destructive ways to Identify moisture and detect concealed leaks just before they escalate into expensive repairs. For Canadian home entrepreneurs coping with Severe weather, infrared know-how has become a video game-changer in flat roof servicing and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes heat-sensing cameras to recognize temperature discrepancies over the surface area of a roof. The essential basic principle is easy: soaked products keep warmth in a different way than dry types.
in the event the Solar warms a roof throughout the day, locations made up of trapped humidity soak up and maintain warmth more time. immediately after sunset, because the roof cools, People wet spots release warmth far more slowly but surely — developing seen “warm places” on an infrared impression.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
regions with saturated insulation.
-
ruined or delaminated roofing products.
-
Drainage difficulties or trapped dampness around seams.
This non-invasive technique permits precise detection without slicing or harming the roofing process.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, especially in business and multi-residential buildings, are specially vulnerable to concealed h2o hurt. conventional inspection approaches like Visible checks or core sampling can skip issues until eventually they become intense.

action 2: Thermal Imaging Capture
experts use handheld or drone-mounted infrared cameras to seize temperature styles through the roof area. These equipment detect warmth radiation and translate it right into a colour-coded picture — purple or yellow places indicate retained heat (probable moisture), when blue or purple areas present cooler, dry sections.
stage 3: details Analysis
The captured images are analysed to detect irregular temperature zones. Every single anomaly is cross-checked with on-web-site visual observations and often humidity meters for confirmation.
phase four: in depth Report
knowledgeable report follows, which include infrared visuals, marked dilemma spots, moisture estimates, and fix recommendations. constructing proprietors can then share this report with their roofing contractor to strategy specific repairs.
Ideal situations for exact Scans
