Flat roofs are trustworthy, useful, and classy — but they can even be challenging. contrary to sloped roofs, where by leaks frequently surface swiftly, flat roof leaks can continue to be concealed for months beneath layers of insulation and membranes. h2o may well journey horizontally in the roofing program, displaying up as stains considerably from its resource. by the point the trouble becomes noticeable, considerable internal destruction could already have happened.
This is when infrared roof scanning is available in. It’s one of the most Superior, non-damaging ways to Track down dampness and detect hidden leaks prior to they escalate into pricey repairs. For Canadian home owners handling Severe temperature, infrared know-how has grown to be a activity-changer in flat roof servicing and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) takes advantage of heat-sensing cameras to recognize temperature discrepancies around the area of the roof. The basic principle is straightforward: soaked resources retain heat in another way than dry kinds.
in the event the Sunshine warms a roof during the day, areas made up of trapped humidity take in and hold warmth lengthier. right after sunset, because the roof cools, These wet spots launch heat a lot more slowly but surely — making seen “warm places” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks under membranes.
-
locations with saturated insulation.
-
Damaged or delaminated roofing components.
-
Drainage problems or trapped dampness around seams.
This non-invasive solution permits accurate detection without chopping or damaging the roofing system.
Why Infrared Scanning Is important for Flat Roofs
