Infrared thermography can be used as a non-destructive method for leak detection in flat roofs. With use of thermal imaging cameras, our qualified technicians will scan the roof and monitor the difference in temperature between wet and dry materials, helping to locate areas of water ingress. This can also flag areas which may be unstable due to hidden rot, and areas which may require further investigation.
London Flat Roofing Ltd recommend undertaking infra red thermal imaging surveillance either early in the morning or late at night, depending on environmental conditions. This allows enough time for the flat roof to have absorbed sufficient solar energy that a temperature differential can be seen. A typical flat roof has little or no moisture between the roof membrane and the insulation/ decking.
When a leak occurs, moisture enters the roof and is absorbed by the insulation or decking. Dry materials heat up and cool down faster than wet materials, and the damp areas require more heat to increase their temperature/ take longer to release their heat. During a sunny day, wet insulation/ decking absorbs more thermal energy than dry insulation/ decking, which means it has more energy to release during the late afternoon and early evening. London Flat Roofing use thermal imaging techniques to highlight such changes and identify both the source and extent of the moisture ingress. Roof deck material can be steel, wood or concrete; the material of the roof deck does not affect the thermal survey.
