Flat roofs are dependable, useful, and trendy — However they may also be difficult. contrary to sloped roofs, wherever leaks generally surface swiftly, flat roof leaks can keep on being hidden for months beneath layers of insulation and membranes. drinking water may possibly vacation horizontally from the roofing program, demonstrating up as stains considerably from its supply. by the point the challenge becomes seen, substantial interior damage may possibly already have happened.
This is where infrared roof scanning is available in. It’s Just about the most State-of-the-art, non-damaging methods to Track down moisture and detect concealed leaks prior to they escalate into highly-priced repairs. For Canadian property owners coping with Intense temperature, infrared technologies has become a recreation-changer in flat roof servicing and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) utilizes warmth-sensing cameras to recognize temperature variances about the floor of a roof. The essential basic principle is easy: moist products keep heat in another way than dry types.
once the Solar warms a roof during the day, areas containing trapped moisture soak up and keep heat more time. following sunset, as the roof cools, those wet places launch heat extra gradually — developing visible “hot spots” on an infrared graphic.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks beneath membranes.
