Thermal imaging can help managers of commercial properties to ‘see’ heat loss and potential underlying water on roof surfaces when we use infra red sensors. Whilst this is also true and possible for smaller dwellings, the drone we use is not viable for this purpose, due its size and safety reasons, for residential buildings.
A London Church contacted us to enquire if we could assess where leaks visible inside the premises’ tower may be coming from. The roof is over two stories high; roof aspects are numerous on the property and there is no safe roof access.
The thermal inspection was carried out before dawn broke and the building heated up overnight to maximise the difference between the exterior temperature and the buildings temperature to make identification of heat loss more apparent. Both a thermal drone inspection using an infrared thermal camera on the drone to seek out potential reasons for the leak causes and a visual drone inspection once the sun had risen was carried out.
Numerous issues were identified and an annotated report showing the specifics provide so that the Church Warden and their sub-contractors could carry out remedial repairs. The thermal inspection clarified potential leak causes, not visible to the human eye or via a standard visible drone inspection.
The end-to-end process took just over a day and a half including the planning, site visit and postproduction. The Church Warden did not have to hire a scaffolder or cherry picker which they advise saved them significant costs they would have otherwise incurred.
“S4G Drone Services were very professional, good value, efficient and quick on communication. They had the findings back to me quickly. I highly recommend them and will be sure to use them again soon on future projects”
