Flat roofs are trustworthy, realistic, and classy — However they can be tricky. compared with sloped roofs, where leaks often show up speedily, flat roof leaks can remain concealed for months beneath levels of insulation and membranes. h2o may possibly vacation horizontally from the roofing technique, displaying up as stains far from its supply. By the time the situation becomes noticeable, considerable internal injury may perhaps already have happened.
This is where infrared roof scanning comes in. It’s Probably the most Highly developed, non-harmful ways to locate humidity and detect concealed leaks just before they escalate into high-priced repairs. For Canadian property proprietors coping with Intense temperature, infrared know-how is becoming a video game-changer in flat roof servicing and diagnostics.
comprehending Infrared Roof Scanning
Infrared roof scanning (also referred to as thermal imaging inspection) works by using heat-sensing cameras to detect temperature differences about the surface of a roof. The fundamental theory is straightforward: wet products keep warmth otherwise than dry ones.
if the sun warms a roof throughout the day, regions containing trapped dampness absorb and keep warmth lengthier. soon after sunset, as being the roof cools, those soaked spots launch heat extra gradually — making seen “incredibly hot spots” on an infrared picture.
By interpreting these temperature patterns, inspectors can pinpoint:
-
Hidden leaks below membranes.
-
places with saturated insulation.
-
broken or delaminated roofing components.
-
Drainage difficulties or trapped moisture near seams.
