Flat roofs are trusted, simple, and stylish — Nevertheless they may also be tricky. in contrast to sloped roofs, exactly where leaks usually appear rapidly, flat roof leaks can continue being hidden for roof drainage maintenance toronto months beneath layers of insulation and membranes. drinking water could journey horizontally from the roofing technique, showing up as stains significantly from its source. by the point the problem becomes obvious, significant interior problems may already have transpired.
This is where infrared roof scanning is available in. It’s Among the most Innovative, non-damaging methods to Identify dampness and detect concealed leaks in advance of they escalate into highly-priced repairs. For Canadian home homeowners addressing Severe temperature, infrared technologies has become a video game-changer in flat roof upkeep and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses warmth-sensing cameras to identify temperature variances to the area of a roof. The basic principle is simple: wet components retain heat in different ways than dry ones.
in the event the Sunshine warms a roof throughout the day, locations containing trapped moisture absorb and maintain heat extended. following sunset, because the roof cools, Those people moist places launch heat much more bit by bit — making seen “warm spots” on an infrared graphic.
By interpreting these temperature designs, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
spots with saturated insulation.
-
ruined or delaminated roofing materials.
-
Drainage challenges or trapped moisture near seams.
This non-invasive method permits exact detection without slicing or harmful the roofing system.
Why Infrared Scanning Is important for Flat Roofs
