/31st October 2017, DRONE MARKET WATCHTM/ In the past, roof inspections and surveys have required time and money in order to access the roof. Certain roofs are more difficult to inspect than others. Roofs with tile or steep grades can make it too difficult to walk around and do a thorough inspection. Until now, roof inspectors walk around the home checking from the street, windows and climbing a ladder to look from the eaves to perform a roof inspection on these more difficult roofs.

„However with already available modern drone (UAV) technology, time and costs for roof inspections have been reduced dramatically and more importantly safety has increased. The most efficient way to perform roof inspection in present days is the aerial survey with drone (UAV). Aerial survey can get a perspective and coverage not humanly possible,“ says Michael Dim, Senior Marketing Executive at Drone Market WatchTM.

Aerial roof inspection is an important factor in property maintenance, whether inspecting a roof prior to a commercial purchase or annual roof inspections then having the capability to conduct speedy and cost effective inspections is a must. Drones (UAVs) equipped with high-resolution thermal cameras provide an excellent survey tool used for a number of building-specific applications, including roof insulation inspection. Improved calibration algorithms can enhance the contrast between hot and cool areas on the roof surface in thermal images. This results in more accurate thermal images (pictures) of different roof insulations or surfaces, which could improve both visual interpretation and computer-based thermal anomaly detection.

Roof inspection is typically performed to detect wet insulation, which is the number one enemy for build-up roofs. Identifying the wet insulation and recovering it at early stage can greatly reduce the maintenance cost and prolong the life span of a roof. Roof inspection with drone (UAV) system equipped with thermal camera stands above all other methods for this purpose according to Drones in Building and Construction Inspection Global Market Outlook 2017 ÷ 2026.  This non-destructive method (NDT) provides a quick, accurate and inexpensive way to find areas of wet insulation and potential leaks that gives maintenance company or personnel the opportunity to limit their roof damage before they become costly.

Thermal patterns can be observed on the roof due to material differences in thermal capacity. During the day, sun heats the roof structure. As wet roof insulation has a much higher thermal capacity, it absorbs and retains more solar energy than dry roof insulation. After sunset, wet roof insulation radiates heat for a longer period of time and cools down slower, causing hot-spots or thermal anomalies which can be detected by a drone (UAV) equipped with thermal infrared camera during the window of uneven heat dissipation.
