Flat roofs are responsible, practical, and classy — Nevertheless they can be tricky. as opposed to sloped roofs, wherever leaks often look quickly, flat roof leaks can continue to be concealed for months beneath levels of insulation and membranes. Water may well journey horizontally from the roofing program, demonstrating up as stains far from its supply. by the point the trouble gets to be noticeable, significant interior damage might have already got happened.
This is when infrared roof scanning comes in. It’s one of the most Highly developed, non-harmful ways to Find moisture and detect hidden leaks just before they escalate into high priced repairs. For Canadian residence owners managing Extraordinary temperature, infrared technological know-how is now a activity-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) uses warmth-sensing cameras to detect temperature dissimilarities about the surface of a roof. The fundamental theory is simple: wet supplies retain heat in different ways than dry types.
in the event the sun warms a roof throughout the day, spots made up of trapped dampness take up and maintain warmth longer. soon after sunset, as being the roof cools, those wet spots launch heat far more slowly — producing noticeable “incredibly hot spots” on an infrared picture.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks underneath membranes.
-
places with saturated insulation.
