Thermographic imaging flat roofs
Thermographic roof surveys are conducted using an infrared camera to identify the locations of thermal irregularities and energy inefficiencies due to destructive water damage within the roof build up.
This diagnostic method is best suited to situations where only a single layer of insulation is between the vapour control layer and the waterproofing membrane. Our analytical report includes visual evidence of the roof’s condition and also quantifies the building’s energy loss, so that we can help the client improve their roof’s thermal efficiency.
Testing Method Key Features
- Decisions for roof repair are based on thermographic imaging which identifies heat loss due to damaged insulation
- Testing single layer roof systems
- Night-time survey photography
Thermographic testing must be performed at night-time when the roof surface has sufficiently cooled. The thermal image instantly shows temperature differences that verify wet and dry areas as moisture conducts heat faster than any parts that are dry, making roof leaks much easier to identify.
