Flat roofs are reputable, practical, and stylish — Nonetheless they can even be tricky. compared with sloped roofs, wherever leaks frequently appear immediately, flat roof leaks can continue to be hidden for months beneath layers of insulation and membranes. drinking water may perhaps vacation horizontally from the roofing system, demonstrating up as stains much from its resource. By the time the condition turns into visible, important internal destruction may well already have happened.
This is where infrared roof scanning comes in. It’s Probably the most Superior, non-damaging ways to Identify humidity and detect concealed leaks before they escalate into highly-priced repairs. For Canadian home proprietors coping with extreme weather, infrared technological know-how is now a game-changer in flat roof routine maintenance and diagnostics.
comprehension Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) works by using heat-sensing cameras to recognize temperature dissimilarities to the area of the roof. The essential principle is simple: soaked products keep heat in another way than dry kinds.
When the Sunshine warms a roof during the day, spots that contains trapped moisture take up and hold heat extended. After sunset, as the roof cools, These soaked places release heat extra gradually — producing seen “incredibly hot spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks underneath membranes.
