Flat roofs are trusted, functional, and trendy — but they may also be tricky. in contrast to sloped roofs, where by leaks often show up quickly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. drinking water may possibly journey horizontally throughout the roofing process, displaying up as stains much from its source. By the time the issue turns into noticeable, significant inside damage could have already got transpired.
This is when infrared roof scanning comes in. It’s Just about the most Highly developed, non-harmful methods to Track down dampness and detect concealed leaks ahead of they escalate into highly-priced repairs. For Canadian assets house owners handling Severe weather conditions, infrared technology is becoming a sport-changer in flat roof servicing and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) employs heat-sensing cameras to establish temperature discrepancies to the surface area of the roof. The essential basic principle is simple: moist elements keep warmth otherwise than dry ones.
once the sun warms a roof during the day, locations containing trapped moisture take in and hold warmth extended. soon after sunset, since the roof cools, All those moist spots launch warmth extra bit by bit — creating noticeable “hot places” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
locations with saturated insulation.
-
destroyed or delaminated roofing elements.
-
Drainage issues or trapped moisture close to seams.
This non-invasive technique allows for precise detection without having slicing or harmful the roofing procedure.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, particularly in professional and multi-residential properties, are notably prone to concealed water harm. regular inspection solutions like visual checks or core sampling can miss challenges until eventually they become serious.
