Flat roofs are reliable, sensible, and stylish — Nonetheless they can even be difficult. in contrast to sloped roofs, exactly where leaks often show up immediately, flat roof leaks can keep on being hidden for months beneath layers of insulation and membranes. h2o may possibly travel horizontally with the roofing program, exhibiting up as stains far from its supply. by the point the trouble gets to be obvious, significant inside damage might have already got happened.
This is when infrared roof scanning is available in. It’s Just about the most State-of-the-art, non-harmful strategies to Identify moisture and detect concealed leaks in advance of they escalate into pricey repairs. For Canadian property owners dealing with Serious weather, infrared technologies is becoming a sport-changer in flat roof maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) employs heat-sensing cameras to determine temperature variances within the surface area of a roof. The basic theory is simple: wet products retain warmth differently than dry kinds.
once the sun warms a roof throughout the day, areas containing trapped moisture absorb and keep warmth longer. immediately after sunset, as the roof cools, These moist places launch heat extra slowly but surely — creating noticeable “sizzling spots” on an infrared image.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks less than membranes.
-
parts with saturated insulation.
-
harmed or delaminated roofing materials.
-
Drainage difficulties or trapped moisture near seams.
This non-invasive method allows for precise detection without slicing or detrimental the roofing system.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, especially in professional and multi-household buildings, are significantly susceptible to concealed h2o damage. common inspection techniques like visual checks or core sampling can overlook problems until finally they develop into severe.
