Flat roofs are reputable, functional, and classy — Nevertheless they can be tricky. not like sloped roofs, the place leaks normally surface promptly, flat roof leaks can remain concealed for months beneath levels of insulation and membranes. Water may possibly vacation horizontally in the roofing process, exhibiting up as stains significantly from its resource. By the time the issue results in being noticeable, important interior destruction may well already have transpired.
This is when infrared roof scanning comes in. It’s Among the most Highly developed, non-harmful strategies to Track down dampness and detect concealed leaks ahead of they escalate into costly repairs. For Canadian home proprietors addressing Serious weather, infrared technology has become a match-changer in flat roof upkeep and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) employs heat-sensing cameras to detect temperature variations to the surface of the roof. The fundamental basic principle is simple: wet supplies keep heat in a different way than dry ones.
if the sun warms a roof throughout the day, spots containing trapped moisture absorb and hold warmth extended. following sunset, as being the roof cools, All those moist spots release heat a lot more slowly but surely — generating seen “hot places” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks less than membranes.
