Flat roofs are dependable, practical, and trendy — Nonetheless they will also be challenging. in contrast to sloped roofs, exactly where leaks typically appear speedily, flat roof leaks can continue being concealed for months beneath levels of insulation and membranes. Water may possibly travel horizontally throughout the roofing program, showing up as stains much from its source. by the point the problem turns into visible, major inner problems may possibly already have transpired.
This is where infrared roof scanning is available in. It’s Among the most Highly developed, non-destructive methods to Identify moisture and detect hidden leaks right before they escalate into expensive repairs. For Canadian home house owners handling Excessive climate, infrared technologies has grown to be a video game-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) uses warmth-sensing cameras to determine temperature differences to the floor of the roof. The essential principle is easy: damp components retain warmth in another way than dry ones.
once the Solar warms a roof during the day, regions made up of trapped moisture soak up and maintain heat lengthier. After sunset, as the roof cools, People wet spots release heat more slowly — generating visible “scorching places” on an infrared picture.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks underneath membranes.
