Flat roofs are dependable, sensible, and trendy — However they can be tricky. Unlike sloped roofs, wherever leaks generally look speedily, flat roof leaks can remain hidden for months beneath layers of insulation and membranes. h2o might journey horizontally through the roofing method, demonstrating up as stains far from its resource. by the point the situation results in being seen, major interior harm may perhaps have already got happened.
This is when infrared roof scanning is available in. It’s Just about the most State-of-the-art, non-harmful strategies to locate dampness and detect hidden leaks prior to they escalate into high-priced repairs. For Canadian house owners coping with Severe climate, infrared technologies happens to be a sport-changer in flat roof servicing and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) uses heat-sensing cameras to detect temperature variations about the floor of a roof. The fundamental basic principle is simple: moist supplies keep heat in a different way than dry ones.
When the sun warms a roof during the day, regions that contains trapped dampness absorb and hold heat longer. After sunset, since the roof cools, People damp places release heat more slowly — building noticeable “warm places” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
locations with saturated insulation.
-
broken or delaminated roofing materials.
-
Drainage problems or trapped humidity near seams.
This non-invasive approach allows for accurate detection with out chopping or harming the roofing technique.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, especially in business and multi-residential structures, are notably prone to concealed water damage. Traditional inspection approaches like visual checks or Main sampling can overlook troubles right up until they develop into serious. Infrared scanning, Then again, detects concerns long before they’re visible.
Here’s why it’s Particularly significant for Canadian flat roofs:
1. Hidden Moisture Beneath the Surface
Flat roofs generally use multiple layers — membrane, insulation, vapour barrier, and deck. A small puncture can allow for h2o to spread between these levels. Infrared scans detect that dampness quickly, even if no visible leak exists.
two. security in opposition to Freeze-Thaw Damage
In Canada’s cold climate, water trapped underneath the membrane can freeze and broaden, causing blisters, cracks, and delamination. Early detection helps prevent this cycle from weakening the composition.
3. lowered mend fees
Infrared engineering identifies the specific area and size of ruined parts, so contractors only repair what’s needed in lieu of replacing the complete roof.
four. prolonged Roof Lifespan
By catching leaks early, infrared scans protect against lengthy-time period deterioration, encouraging roofs previous closer to their full envisioned lifespan — generally twenty five to 30 decades.
five. assistance for guarantee and insurance policies Claims
numerous makers and insurers now recognise thermal imaging reviews as legitimate documentation for preventive maintenance or leak resource identification.
How Infrared Roof Scans Work

stage 1: website planning
The inspection is generally scheduled immediately after sunset or early morning, if the temperature difference between wet and dry components is most obvious. The roof should be clean up, dry, and free of particles to prevent distorted readings.
action 2: Thermal Imaging Capture
specialists use handheld or drone-mounted infrared cameras to capture temperature styles throughout the roof surface. These equipment detect heat radiation and translate it right into a colour-coded graphic — red or yellow places show retained heat (achievable moisture), while blue or purple spots demonstrate cooler, dry sections.
stage three: knowledge Assessment
The captured pictures are analysed to recognize irregular temperature zones. Every single anomaly is cross-checked with on-website visual observations and in some cases dampness meters for confirmation.
action four: in depth Report
A professional report follows, which include infrared photos, marked dilemma locations, dampness estimates, and maintenance recommendations. creating owners can then share this report with their roofing contractor to program specific repairs.
excellent ailments for Accurate Scans
