Flat roofs are reliable, functional, and classy — but they may also be tricky. compared with sloped roofs, the place leaks frequently seem speedily, flat roof leaks can continue being concealed for months beneath layers of insulation and membranes. Water may possibly vacation horizontally in the roofing program, displaying up as stains much from its source. by the point the condition turns into visible, considerable inside destruction may perhaps have already got occurred.
This is where infrared roof scanning comes in. It’s Among the most Superior, non-destructive ways to locate dampness and detect hidden leaks prior to they escalate into costly repairs. For Canadian home entrepreneurs dealing with Serious climate, infrared technological know-how has become a activity-changer in flat roof routine maintenance and diagnostics.
knowing Infrared Roof Scanning
Infrared roof scanning (often known as thermal imaging inspection) works by using warmth-sensing cameras to discover temperature distinctions about the floor of the roof. The essential theory is straightforward: soaked materials keep warmth in another way than dry types.
in the event the sun warms a roof during the day, parts containing trapped dampness soak up and keep warmth lengthier. After sunset, since the roof cools, People soaked spots launch heat extra slowly and gradually — making seen “scorching spots” on an infrared impression.
By interpreting these temperature designs, inspectors can pinpoint:
-
concealed leaks beneath membranes.
-
Areas with saturated insulation.
-
Damaged or delaminated roofing materials.
-
Drainage challenges or trapped moisture around seams.
