Flat roofs are dependable, functional, and trendy — but they can also be tricky. Unlike sloped roofs, the place leaks generally look promptly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. drinking water may perhaps vacation horizontally with the roofing procedure, exhibiting up as stains much from its supply. By the time the situation results in being visible, major inner damage may perhaps already have transpired.
This is when infrared roof scanning comes in. It’s Probably the most advanced, non-harmful methods to locate moisture and detect hidden leaks before they escalate into high priced repairs. For Canadian assets owners managing Severe temperature, infrared engineering has become a video game-changer in flat roof servicing and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes warmth-sensing cameras to determine temperature distinctions to the surface area of the roof. The essential principle is straightforward: soaked supplies retain heat otherwise than dry ones.
if the Sunlight warms a roof throughout the day, locations made up of trapped moisture absorb and maintain warmth longer. After sunset, as website the roof cools, All those wet spots launch heat additional little by little — developing obvious “hot places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks below membranes.
-
regions with saturated insulation.
-
harmed or delaminated roofing resources.
-
Drainage difficulties or trapped moisture in close proximity to seams.
This non-invasive strategy allows for accurate detection with out cutting or harming the roofing method.
Why Infrared Scanning Is important for Flat Roofs
