Flat roofs are trustworthy, useful, and trendy — However they may also be tricky. not like sloped roofs, wherever leaks often show up quickly, flat roof leaks can stay hidden for months beneath layers of insulation and membranes. Water could vacation horizontally in the roofing program, displaying up as stains significantly from its resource. By the time the trouble gets to be noticeable, substantial inner damage might already have transpired.
This is where infrared roof scanning comes in. It’s Among the most State-of-the-art, non-destructive strategies to locate humidity and detect hidden leaks in advance of they escalate into high-priced repairs. For Canadian residence homeowners working with Extraordinary weather conditions, infrared know-how is becoming a game-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) makes use of warmth-sensing cameras to identify temperature distinctions over the floor of the roof. The basic basic principle is straightforward: moist resources retain warmth otherwise than dry kinds.
if the Solar warms a roof throughout the day, parts made up of trapped humidity soak up and maintain warmth extended. right after sunset, because the roof cools, These damp places release heat more little by little — building noticeable “very hot places” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks underneath membranes.
-
regions with saturated insulation.
-
destroyed or delaminated roofing resources.
-
Drainage difficulties or trapped moisture in close proximity to seams.
