Flat roofs are responsible, functional, and classy — However they can even be tricky. compared with sloped roofs, in which leaks frequently show up speedily, flat roof leaks can remain concealed for months beneath levels of insulation and membranes. drinking water might journey horizontally with the roofing program, exhibiting up as stains far from its source. By the time the condition becomes seen, substantial interior harm might already have occurred.
This is where infrared roof scanning comes in. It’s The most Superior, non-destructive methods to Track down humidity and detect concealed leaks right before they escalate into high priced repairs. For Canadian home house owners working with Serious temperature, infrared technological know-how happens to be a activity-changer in flat roof maintenance and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses warmth-sensing cameras to determine temperature variations around the surface of the roof. The essential basic principle is straightforward: damp components retain heat differently than dry types.
in the event the Sunshine warms a roof throughout the day, regions made up of trapped moisture soak up and keep heat lengthier. immediately after sunset, as the roof cools, Individuals damp spots launch heat additional bit by bit — producing seen “sizzling places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks below membranes.
