Flat roofs are dependable, sensible, and stylish — but they can be tricky. not like sloped roofs, where by leaks normally seem rapidly, flat roof leaks can keep on being concealed for months beneath layers of insulation and membranes. drinking water might journey horizontally with the roofing technique, showing up as stains considerably from its supply. By the time the challenge will become obvious, substantial inside destruction might already have transpired.
This is where infrared roof scanning is available in. It’s The most Innovative, non-damaging strategies to Track down moisture and detect concealed leaks just before they escalate into expensive repairs. For Canadian house house owners addressing Excessive weather, infrared engineering has grown to be a recreation-changer in flat roof upkeep and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) utilizes heat-sensing cameras to detect temperature differences around the floor of a roof. The fundamental basic principle is straightforward: damp elements retain heat in a different way than dry types.
in the event the Sunshine warms a roof throughout the day, areas containing trapped dampness soak up and hold heat extended. soon after sunset, given that the roof cools, People moist spots release warmth extra slowly — creating seen “scorching spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks less than membranes.
