Flat roofs are trustworthy, simple, and stylish — Nonetheless they can also be tough. Unlike sloped roofs, in which leaks typically seem swiftly, flat roof leaks can stay concealed for months beneath layers of insulation and membranes. h2o may perhaps journey horizontally from the roofing procedure, displaying up as stains much from its source. by the point the condition turns into obvious, sizeable interior hurt may possibly have already got transpired.
This is when infrared roof scanning is available in. It’s Just about the most Innovative, non-harmful strategies to locate dampness and detect hidden leaks ahead of they escalate into costly repairs. For Canadian property entrepreneurs working with Severe temperature, infrared technologies is becoming a recreation-changer in flat roof maintenance and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) utilizes heat-sensing cameras to recognize temperature variations over the surface of a roof. The fundamental theory is straightforward: damp supplies retain warmth in a different way than dry kinds.
once the Solar warms a roof during the day, locations containing trapped humidity absorb and maintain heat lengthier. right after sunset, given that the roof cools, People soaked spots release heat more slowly and gradually — developing obvious “very hot spots” on an infrared graphic.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks underneath membranes.
