Flat roofs are dependable, practical, and trendy — However they can also be tough. contrary to sloped roofs, in which leaks usually look speedily, flat roof leaks can remain concealed for months beneath layers of insulation and membranes. drinking water may well travel horizontally in the roofing process, demonstrating up as stains much from its supply. By the time the condition gets to be seen, considerable internal hurt may perhaps already have transpired.
This is where infrared roof scanning comes in. It’s The most Superior, non-destructive ways to locate dampness and detect hidden leaks right before they escalate into high priced repairs. For Canadian assets owners addressing Extraordinary weather conditions, infrared technological know-how is now a video game-changer in flat roof maintenance and diagnostics.
Understanding Infrared Roof Scanning
Infrared roof scanning (also known as thermal imaging inspection) makes use of warmth-sensing cameras to determine temperature variances within the floor of a roof. The essential basic principle is straightforward: wet products keep warmth differently than dry types.
When the Sunshine warms a roof throughout the day, locations made up of trapped humidity absorb and hold warmth lengthier. following sunset, because the roof cools, All those damp places launch warmth more gradually — producing noticeable “warm places” on an infrared impression.
By interpreting these temperature styles, inspectors can pinpoint:
-
concealed leaks less than membranes.
-
places with saturated insulation.
-
broken or delaminated roofing components.
-
Drainage difficulties or trapped dampness close to seams.
This non-invasive technique allows for precise detection devoid of cutting or harming the roofing process.
Why Infrared Scanning Is important for Flat Roofs
Flat roofs, particularly in professional and multi-household properties, are specifically prone to hidden water injury. regular inspection techniques like Visible checks or core sampling can pass up difficulties until eventually they become intense.
