Flat roofs are trusted, functional, and stylish — Nevertheless they can be tough. Unlike sloped roofs, in which leaks normally appear swiftly, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may well vacation horizontally throughout the roofing process, exhibiting up as stains significantly from its source. by the point the challenge gets to be visible, considerable internal hurt could have already got transpired.
This is where infrared roof scanning comes in. It’s One of the more Innovative, non-harmful ways to Find moisture and detect concealed leaks ahead of they escalate into high-priced repairs. For Canadian assets owners managing Excessive climate, infrared technological innovation is now a sport-changer in flat roof servicing and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses warmth-sensing cameras to recognize temperature distinctions to the floor of a roof. The fundamental theory is straightforward: damp resources keep heat in different ways than dry kinds.
if the Sunlight warms a roof throughout the day, regions containing trapped humidity take in and maintain warmth extended. immediately after sunset, as the roof cools, These moist spots launch warmth extra little by little — making obvious “hot spots” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
spots with saturated insulation.
-
Damaged or delaminated roofing resources.
-
Drainage concerns or trapped moisture around seams.
