Flat roofs are dependable, sensible, and classy — but they will also be challenging. Unlike sloped roofs, where leaks usually surface immediately, flat roof leaks can stay hidden for months beneath layers of insulation and membranes. Water could vacation horizontally in the roofing process, demonstrating up as stains considerably from its resource. by the point the situation becomes obvious, substantial internal hurt may possibly already have occurred.
This is when infrared roof scanning comes in. It’s one of the most Sophisticated, non-destructive strategies to Identify humidity and detect concealed leaks just before they escalate into costly repairs. For Canadian residence entrepreneurs managing Extraordinary climate, infrared technologies has grown to be a sport-changer in flat roof routine maintenance and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) employs warmth-sensing cameras to identify temperature distinctions to the area of a roof. The essential principle is easy: moist materials retain heat differently than dry kinds.
if the Solar warms a roof during the day, parts that contains trapped moisture take in and hold warmth extended. soon after sunset, as the roof cools, Those people moist spots release warmth extra bit by bit — building visible “scorching places” on an infrared graphic.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks under membranes.
-
locations with saturated insulation.
-
harmed or delaminated roofing materials.
-
Drainage difficulties or trapped moisture near seams.
