Flat roofs are reliable, useful, and trendy — Nonetheless they may also be challenging. in contrast to sloped roofs, where by leaks normally show up speedily, flat roof leaks can continue being concealed for months beneath layers of insulation and membranes. drinking water may perhaps travel horizontally through the roofing procedure, exhibiting up as stains far from read more its source. by the point the challenge turns into visible, significant interior damage may have already got transpired.
This is when infrared roof scanning comes in. It’s Just about the most State-of-the-art, non-damaging strategies to locate humidity and detect concealed leaks prior to they escalate into high priced repairs. For Canadian residence house owners coping with Extraordinary temperature, infrared technologies has grown to be a video game-changer in flat roof routine maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) takes advantage of warmth-sensing cameras to establish temperature distinctions around the area of the roof. The fundamental principle is straightforward: wet components retain heat differently than dry types.
in the event the sun warms a roof throughout the day, spots containing trapped moisture take up and maintain warmth extended. soon after sunset, since the roof cools, Those people wet spots release heat a lot more slowly and gradually — creating seen “sizzling spots” on an infrared image.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
Areas with saturated insulation.
-
Damaged or delaminated roofing components.
-
Drainage problems or trapped dampness in the vicinity of seams.
This non-invasive approach permits exact detection with no cutting or harming the roofing program.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, specifically in commercial and multi-household properties, are significantly vulnerable to hidden water problems. regular inspection procedures like visual checks or core sampling can skip problems right until they turn out to be severe.
