Flat roofs are responsible, realistic, and trendy — but they may also be difficult. not like sloped roofs, the place leaks usually show up quickly, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. h2o might vacation horizontally through the roofing process, showing up as stains much from its resource. By the time the trouble results in being seen, substantial inner problems may perhaps already have happened.
This is when infrared roof scanning comes in. It’s Just about the most Innovative, non-harmful ways to locate dampness and detect concealed leaks before they escalate into costly repairs. For Canadian house homeowners handling Extraordinary climate, infrared engineering is now a recreation-changer in flat roof maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) takes advantage of heat-sensing cameras to establish temperature discrepancies on the surface of the roof. The basic principle is straightforward: damp resources retain warmth in a different way than dry ones.
once the Solar warms a roof during the day, areas containing trapped humidity take in and maintain warmth lengthier. immediately after sunset, as being the roof cools, These damp places launch heat additional gradually — building visible “scorching places” on an infrared image.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks under membranes.
-
spots with saturated insulation.
-
destroyed or delaminated roofing elements.
-
Drainage problems or trapped moisture in close proximity to seams.
This non-invasive approach permits exact detection with no chopping or damaging the roofing program.
Why Infrared Scanning Is Essential for Flat Roofs
