Flat roofs are responsible, practical, and classy — However they can even be challenging. compared with sloped roofs, exactly where leaks typically appear rapidly, flat roof leaks can continue being hidden for months beneath layers of insulation and membranes. h2o may possibly vacation horizontally from the roofing method, demonstrating up as stains considerably from its source. by the point the situation becomes noticeable, significant internal problems might already have transpired.
This is where infrared roof scanning comes in. It’s The most advanced, non-destructive ways to Identify dampness and detect concealed leaks before they escalate into highly-priced repairs. For Canadian home proprietors working with Severe weather conditions, infrared engineering is becoming a video game-changer in flat roof maintenance and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also called thermal imaging inspection) employs warmth-sensing cameras to establish temperature discrepancies to the surface of the roof. The basic theory is straightforward: wet elements keep warmth in a different way than dry ones.
once the sun warms a roof throughout the day, regions made up of trapped humidity take up and maintain heat lengthier. After sunset, because the roof cools, These moist places launch warmth more slowly — producing seen “sizzling spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
concealed leaks less than membranes.
-
locations with saturated insulation.
-
destroyed or delaminated roofing resources.
-
Drainage troubles or trapped dampness around seams.
This non-invasive tactic permits correct detection without the need of reducing or harming the roofing program.
Why Infrared Scanning Is important for Flat Roofs
