Flat roofs are dependable, useful, and classy — Nevertheless they can be tricky. as opposed to sloped roofs, the place leaks frequently show up swiftly, flat roof leaks can continue to be hidden for months beneath levels of insulation and membranes. drinking water may well travel horizontally from the roofing program, exhibiting up as stains far from its resource. by the point the trouble gets to be noticeable, sizeable inside destruction might already have happened.
This is where infrared roof scanning comes in. It’s one of the most State-of-the-art, non-damaging strategies to locate moisture and detect hidden leaks in advance of they escalate into high priced repairs. For Canadian assets house owners handling extreme weather conditions, infrared technology has become a recreation-changer in flat roof maintenance and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) employs warmth-sensing cameras to discover temperature distinctions to the floor of a roof. The fundamental theory is easy: soaked products retain heat in another way than dry types.
When the sun warms a roof throughout the day, spots made up of trapped moisture take up and keep heat longer. right after sunset, because the roof cools, Individuals wet spots release heat extra slowly and gradually — making obvious “sizzling places” on an infrared impression.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks less than membranes.
-
places with saturated insulation.
-
harmed or delaminated roofing components.
