Flat roofs are responsible, realistic, and stylish — Nevertheless they can also be challenging. contrary to sloped roofs, the place leaks often surface speedily, flat roof leaks can continue being hidden for months beneath layers of insulation and membranes. h2o may possibly vacation horizontally throughout the roofing technique, showing up as stains significantly from its supply. By the time the situation turns into seen, important inner hurt may already have happened.
This is where infrared roof scanning comes in. It’s one of the most Highly developed, non-destructive ways to Find moisture and detect concealed leaks in advance of they escalate into high-priced repairs. For Canadian property proprietors handling Excessive climate, infrared engineering has become a recreation-changer in flat roof servicing and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) uses warmth-sensing cameras to establish temperature discrepancies around the surface area of the roof. The fundamental principle is simple: wet resources retain warmth otherwise than dry types.
in the event the sun warms a roof during the day, locations containing trapped dampness take in and maintain warmth more time. right after sunset, since the roof cools, People soaked spots release warmth additional little by little — creating visible “sizzling places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks beneath membranes.
-
spots with saturated insulation.
-
ruined or delaminated roofing elements.
-
Drainage challenges or trapped moisture close to seams.
This non-invasive strategy allows for accurate detection devoid of cutting or harming the roofing procedure.
