Flat roofs are responsible, realistic, and trendy — Nevertheless they can also be challenging. not like sloped roofs, the place leaks normally appear rapidly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. h2o could journey horizontally in the roofing procedure, showing up as stains much from its supply. By the time the issue becomes visible, important inner damage may possibly already have occurred.
This is when infrared roof scanning comes in. It’s The most Highly developed, non-destructive techniques to locate humidity and detect hidden leaks right before they escalate into high priced repairs. For Canadian residence proprietors addressing extreme climate, infrared technology has grown to be a game-changer in flat roof servicing and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) takes advantage of warmth-sensing cameras to recognize temperature differences over the area of the roof. The essential theory is straightforward: moist components keep warmth differently than dry ones.
if the Solar warms a roof throughout the day, locations that contains trapped dampness absorb and maintain warmth more time. just after sunset, because the roof cools, These soaked places release heat more slowly — building noticeable “warm places” on an infrared graphic.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks beneath membranes.
-
regions with saturated insulation.
-
harmed or delaminated roofing supplies.
-
Drainage difficulties or trapped humidity around seams.
This non-invasive technique allows for exact detection without the need of chopping or detrimental the roofing procedure.
Why Infrared Scanning Is Essential for Flat Roofs
