Flat roofs are dependable, functional, and classy — but they can be tough. Unlike sloped roofs, the place leaks usually surface speedily, flat roof leaks can keep on being concealed for months beneath layers of insulation and membranes. Water may travel horizontally through the roofing system, exhibiting up as stains considerably from its source. by the point the challenge will become visible, considerable inner problems may well have already got occurred.
This is when infrared roof scanning comes in. It’s The most Highly developed, non-harmful methods to Find humidity and detect concealed leaks right before they escalate into highly-priced repairs. For Canadian house owners working with Serious climate, infrared technology is becoming a activity-changer in flat roof upkeep and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) takes advantage of heat-sensing cameras to establish temperature distinctions within the surface area of a roof. The basic theory is easy: moist components keep warmth in different ways than dry kinds.
if the Solar warms a roof during the day, spots that contains trapped moisture take up and hold heat for a longer period. soon after sunset, since the roof cools, Individuals moist places launch warmth a lot more slowly but surely — building seen “sizzling places” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks underneath membranes.
