Flat roofs are trusted, practical, and classy — Nevertheless they can also be challenging. as opposed to sloped roofs, in which leaks usually look speedily, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. drinking water may journey horizontally with the roofing system, demonstrating up as stains much from its supply. By the time the situation turns into visible, considerable interior problems could have already got transpired.
This is where infrared roof scanning comes in. It’s Probably the most Superior, non-harmful methods to Track down dampness and detect hidden leaks right before they escalate into pricey repairs. For Canadian residence owners addressing Excessive temperature, infrared engineering is becoming a video game-changer in flat roof maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) makes use of heat-sensing cameras to recognize temperature dissimilarities within the floor of the roof. The basic basic principle is straightforward: damp supplies retain warmth differently than dry kinds.
once the Solar warms a roof during the day, locations made up of trapped humidity take up and keep warmth for a longer time. immediately after sunset, as the roof cools, These soaked places launch heat a lot more bit by bit — producing seen “very hot spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
spots with saturated insulation.
-
weakened or delaminated roofing resources.
-
Drainage concerns or trapped dampness in close proximity to seams.
This non-invasive tactic permits accurate detection devoid of reducing or detrimental the roofing procedure.
Why Infrared Scanning Is important for Flat Roofs
