Flat roofs are responsible, useful, and stylish — Nonetheless they will also be tricky. compared with sloped roofs, where by leaks generally seem promptly, flat roof leaks can continue being concealed for months beneath layers of insulation and membranes. h2o may well journey horizontally through the roofing technique, showing up as stains considerably from its resource. By the time the challenge results in being obvious, substantial interior problems may have already got happened.
This is when infrared roof scanning comes in. It’s One of the more State-of-the-art, non-destructive ways to Identify humidity and detect hidden leaks just before they escalate into expensive repairs. For Canadian house house owners addressing Severe climate, infrared technological innovation has become a recreation-changer in flat roof routine maintenance and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) works by using warmth-sensing cameras to recognize temperature distinctions around the surface of the roof. The fundamental theory is straightforward: wet elements keep heat in a different way than dry kinds.
if the Sunlight warms a roof during the day, regions that contains trapped humidity take in and hold warmth more time. right after sunset, as the roof cools, Those people wet spots release warmth far more slowly and gradually — making obvious “hot spots” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks less than membranes.
-
spots with saturated insulation.
-
ruined or delaminated roofing elements.
