Flat roofs are trusted, practical, and stylish — but they will also be tricky. contrary to sloped roofs, in which leaks generally appear rapidly, flat roof leaks can continue being hidden for months beneath levels of insulation and membranes. h2o might journey horizontally in the roofing system, showing up as stains significantly from its supply. By the time the issue turns into obvious, significant internal destruction may well have already got happened.
This is where infrared roof scanning comes in. It’s One of the more Innovative, non-damaging strategies to Identify moisture and detect concealed leaks right before they escalate into expensive repairs. For Canadian residence proprietors addressing Severe weather conditions, infrared technologies has grown to be a game-changer in flat roof routine maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) employs warmth-sensing cameras to recognize temperature dissimilarities around the surface of the roof. The essential basic principle is easy: damp elements retain warmth otherwise than dry ones.
if the Solar warms a roof throughout the day, spots containing trapped dampness soak up and maintain heat longer. immediately after sunset, as the roof cools, those damp spots release heat more slowly — making noticeable “incredibly hot places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks less than membranes.
-
Areas with saturated insulation.
-
weakened or delaminated roofing materials.
-
Drainage problems or trapped dampness in the vicinity of seams.
This non-invasive technique permits correct detection without chopping or harming the roofing procedure.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, especially in professional and multi-residential buildings, are specially at risk of hidden drinking water hurt. regular inspection techniques like visual checks or Main sampling can skip difficulties until they develop into serious.

The inspection is normally scheduled immediately after sunset or early morning, if the temperature distinction between moist and dry products is most noticeable. The roof have to be thoroughly clean, dry, and freed from debris in order to avoid distorted readings.
phase two: Thermal Imaging seize
professionals use handheld or drone-mounted infrared cameras to seize temperature patterns through the roof area. These devices detect heat radiation and translate it into a colour-coded graphic — pink or yellow locations show retained warmth (probable dampness), whilst blue or purple areas display cooler, dry sections.
move three: facts Investigation
The captured photos are analysed to recognize irregular temperature zones. Each individual anomaly is cross-checked with on-site visual observations and occasionally moisture meters for confirmation.
Step 4: thorough Report
a specialist report follows, together with infrared pictures, marked problem spots, humidity estimates, and repair service recommendations. Building proprietors can then share this report with their roofing contractor to prepare qualified repairs.
Ideal problems for precise Scans
to accomplish reputable final results, specific environmental and physical problems has to be fulfilled — specially in Canada’s assorted local weather:
-
very clear skies and dry disorders: Rain or snow can great the floor and distort readings.
