Flat roofs are reputable, simple, and trendy — Nonetheless they will also be tricky. in contrast to sloped roofs, the place leaks usually seem immediately, flat roof leaks can continue being concealed for months beneath levels of insulation and membranes. Water might journey horizontally with the roofing procedure, displaying up as stains much from its source. by the point the situation gets to be seen, substantial internal injury may possibly already have transpired.
This is where infrared roof scanning comes in. It’s Probably the most Sophisticated, non-damaging methods to Identify moisture and detect concealed leaks before they escalate into expensive repairs. For Canadian residence house owners managing Extraordinary weather conditions, infrared technological innovation has become a game-changer in flat roof maintenance and diagnostics.
being familiar with Infrared Roof Scanning
Infrared roof scanning (often called thermal imaging inspection) employs warmth-sensing cameras to establish temperature variations around the floor of the roof. The essential principle is straightforward: wet supplies retain heat differently than dry ones.
When the Sunshine warms a roof throughout the day, spots containing trapped moisture soak up and keep heat longer. immediately after sunset, since the roof cools, People soaked places release heat far more bit by bit — developing obvious “hot places” on an infrared graphic.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
-
locations with saturated insulation.
-
Damaged or delaminated roofing products.
-
Drainage problems or trapped moisture around seams.
This non-invasive method allows for precise detection without slicing or detrimental the roofing process.
Why Infrared Scanning Is Essential for Flat Roofs
