Flat roofs are responsible, realistic, and classy — However they will also be difficult. compared with sloped roofs, in which leaks generally seem swiftly, flat roof leaks can keep on being hidden for months beneath layers of insulation and membranes. drinking water may possibly travel horizontally in the roofing program, demonstrating up as stains much from its supply. By the time the problem will become noticeable, sizeable interior damage may perhaps already have happened.
This is when infrared roof scanning is available in. It’s The most advanced, non-harmful ways to Track down humidity and detect concealed leaks ahead of they escalate into expensive repairs. For Canadian house house owners working with extreme weather, infrared technological know-how happens to be a match-changer in flat roof routine maintenance and diagnostics.
knowledge Infrared Roof Scanning
Infrared roof scanning (generally known as thermal imaging inspection) uses warmth-sensing cameras to identify temperature discrepancies around the surface area of a roof. The essential theory is simple: moist components retain warmth differently than dry kinds.
When the Sunlight warms a roof during the day, areas that contains trapped moisture take up and keep heat for a longer period. right after sunset, as being the roof cools, All those moist spots release heat extra gradually — producing noticeable “hot places” on an infrared picture.
By interpreting these temperature styles, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
locations with saturated insulation.
-
destroyed or delaminated roofing materials.
-
Drainage difficulties or trapped moisture around seams.
This non-invasive tactic permits correct detection without the need of cutting or detrimental the roofing system.
