Flat roofs are responsible, useful, and trendy — Nonetheless they may also be challenging. in contrast to sloped roofs, where leaks usually surface quickly, flat roof leaks can remain hidden for months beneath layers of insulation and membranes. Water may perhaps journey horizontally throughout the roofing program, demonstrating up as stains far from its supply. by the point the trouble gets to be seen, significant inner harm might already have transpired.
This is when infrared roof scanning is available in. It’s One of the more Sophisticated, non-damaging techniques to Find dampness and detect hidden leaks just before they escalate into pricey repairs. For Canadian property owners handling Intense temperature, infrared know-how has become a video game-changer in flat roof upkeep and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) utilizes warmth-sensing cameras to recognize temperature dissimilarities within the floor of the roof. The essential theory is straightforward: damp supplies retain warmth otherwise than dry types.
if the Sunshine warms a roof during the day, spots made up of trapped humidity soak up and maintain warmth for a longer period. After sunset, because the roof cools, Individuals damp places launch heat more bit by bit — making seen “very hot places” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
