Flat roofs are trusted, sensible, and stylish — Nonetheless they will also be difficult. Unlike sloped roofs, where by leaks generally show up quickly, flat roof leaks can continue being concealed for months beneath levels of insulation and membranes. Water may possibly vacation horizontally through the roofing technique, demonstrating up as stains considerably from its source. by the point the problem gets noticeable, substantial inner problems might have already got occurred.
This is when infrared roof scanning comes in. It’s one of the most Sophisticated, non-damaging techniques to locate dampness and detect hidden leaks before they escalate into high-priced repairs. For Canadian home proprietors handling Intense weather, infrared know-how happens to be a game-changer in flat roof servicing and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) uses warmth-sensing cameras to identify temperature distinctions within the surface of a roof. The essential basic principle is straightforward: soaked elements retain warmth in different ways than dry types.
When the Solar warms a roof during the day, regions that contains trapped dampness take up and hold warmth longer. just after sunset, given that the roof cools, Those people moist places release warmth additional bit by bit — developing noticeable “incredibly hot places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
locations with saturated insulation.
-
Damaged or delaminated roofing supplies.
-
Drainage challenges or trapped dampness in close proximity to seams.
This non-invasive solution allows for exact detection without slicing or damaging the roofing procedure.
Why Infrared Scanning Is Essential for Flat Roofs
