Flat roofs are dependable, practical, and stylish — Nevertheless they may also be tricky. not like sloped roofs, wherever leaks generally show up quickly, flat roof leaks can continue to be hidden for months beneath levels of insulation and membranes. Water might travel horizontally with the roofing system, exhibiting up as stains significantly from its source. by the point the challenge will become obvious, important interior injury may perhaps have already got transpired.
This is where infrared roof scanning comes in. It’s The most State-of-the-art, non-destructive strategies to Identify humidity and detect concealed leaks ahead of they escalate into high priced repairs. For Canadian assets homeowners coping with Serious temperature, infrared engineering has become a recreation-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) utilizes heat-sensing cameras to identify temperature variances on the floor of the roof. The fundamental principle is easy: moist products keep heat in a different way than dry ones.
once the sun warms a roof during the day, places that contains trapped dampness soak up and hold warmth for a longer period. soon after sunset, because the roof cools, All those damp spots release warmth much more gradually — developing visible “sizzling spots” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks under membranes.
-
places with saturated insulation.
-
broken or delaminated roofing products.
-
Drainage problems or trapped dampness around seams.
This non-invasive tactic permits correct detection without having slicing or harming the roofing technique.
Why Infrared Scanning Is Essential for Flat Roofs
Flat roofs, specifically in industrial and multi-residential properties, are particularly at risk of hidden drinking water destruction. common inspection procedures like Visible checks or core sampling can overlook challenges till they become extreme.
