Flat roofs are trustworthy, sensible, and classy — Nevertheless they can be difficult. Unlike sloped roofs, in which leaks often show up quickly, flat roof leaks can keep on being hidden for months beneath levels of insulation and membranes. h2o may well travel horizontally throughout the roofing system, showing up as stains far from its source. by the point the trouble becomes visible, important inside damage could already have occurred.
This is when infrared roof scanning comes in. It’s Probably the most Superior, non-damaging techniques to Track down dampness and detect concealed leaks before they escalate into high-priced repairs. For Canadian house homeowners addressing extreme weather, infrared know-how is becoming a video game-changer in flat roof upkeep and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) takes advantage of heat-sensing cameras to determine temperature variances to the floor of the roof. The essential basic principle is easy: damp components keep warmth in a different way than dry kinds.
in the event the Sunshine warms a roof throughout the day, places made up of trapped dampness take up and maintain heat lengthier. following sunset, given that the roof cools, People moist spots launch heat much more bit by bit — building visible “sizzling places” on an infrared image.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
Areas with saturated insulation.
-
weakened or delaminated roofing materials.
-
Drainage difficulties or trapped moisture near seams.
This non-invasive approach allows for exact detection without the need of slicing or harming the roofing method.
