Aerial photography with drones for maintenance and inspection
It used to be unthinkable to use aerial photography for maintenance, assessment or documentation in the private sector or even on a smaller scale. Thanks to powerful unmanned aerial vehicles (UAV, popularly known as drone), damage documentation or roof inspection is now affordable for every homeowner. Whether residential or commercial, it doesn't matter to us. Non-destructive, non-contact and comprehensive, problems with building insulation or facade insulation can be detected by thermal imaging thermography using a drone. The surveyor can even watch the drone pilot in real time, make special requests and evaluate the data directly, if desired. Immediate results and appraisals of hard-to-reach areas are thus easily possible. However, UAVs are not only used in the private sector, but also for projects that affect infrastructure. These can include, for example, damage to factory chimneys or the inspection of wind turbines or power lines. The advantages are obvious: it is fast, safe and delivers meaningful results thanks to high-resolution cameras. Particularly in the case of dangerously high structures or parts of buildings that are difficult to access (e.g. dilapidated factories), the risk to people can be reduced to virtually zero, as no one has to climb up to carry out a visual inspection.
The advantages of a damage or roof inspection by drone

High-resolution photos with 48MP and up to 16x optical zoom document even minor damage
No risk for people who need to go to dangerous areas or high rooftops
Our drone pilots have years of experience with drones
Our drones are state of the art, suitable for industrial purposes, insured and registered
Thermal imaging technology can be used to quickly detect wet or leaking roofs, providing an overview before remediation work is done
Cost-efficient & quick overview
No need for expensive scaffolding to inspect facades, roofs or building damage
Play it safe before buying a home, a drone inspection can help with purchase decisions or negotiations
Drones provide a quick and accurate overview of the condition and help plan further steps
Check facade insulation with aerial photos
When insulating facades, it is important to detect leaks and thermal bridges quickly so that no energy is wasted. In addition, such problems can lead to consequential damage, such as leaking roofs and the associated water ingress. From below, such damage is often impossible or impossible to detect. Not only because damage often occurs on or around the roof, but also because not every building is accessible from all sides. Structural or technical reasons can make a conventional inspection of the building insulation difficult or even impossible. Our drones, on the other hand, can get almost anywhere and provide high-resolution photos and 3D models with accurate measurement data. Video recordings and thermography with exact thermal measurement data, which is so important for the assessment of facade insulation, are also possible. A thermal image shows leaks and thermal bridges that would otherwise be invisible to the human eye.
Damage documentation from the air
A bird's eye view often provides the best overview. In the case of accidents, disasters or natural disasters, an assessment of the situation through aerial photography with drones has become indispensable. Unclear causes are often revealed by a view from above and the entire extent of a damage event can thus be recorded and documented with the drone - all without putting people in danger. Even if a walkable flat roof should be available, depending on the situation, it is often not appropriate to place additional weight on a damaged building. Performing a roof inspection without human intervention is therefore only possible if technical aids such as a drone are used.
Panoramic photography and photogrammetry using drones
Many types of drones are used for surveying and documenting construction projects. But often a simple aerial photo or even a 360° panorama is not enough to accurately assess an area. Surveying on the ground can be all the more difficult for large projects that are difficult to access. This is where the power of photogrammetry can help. This technology makes it possible to create meaningful and very precise 3D models by precisely measuring the height differences of individual points. The best known example of such a survey with photogrammetry are the Egyptian pyramids, whose secrets could be unraveled a good deal further through research from the air. Last but not least, archaeologists and other scientists are also increasingly turning to aerial photography at the local level to track down long-forgotten traces of buildings, settlements or changes in nature. In everyday life, photogrammetry is used with drones to precisely survey properties or entire neighborhoods and accurately map existing buildings and landscape features. Many parameters can be derived from these 3D models that would be impossible to capture at all from the ground. A roof survey, for example, becomes much easier if the slopes and angles are already taken into account, as is the case with 3D photogrammetry.
Helping to shape the future through aerial photography
When planning new construction or infrastructure projects, aerial photographs help to ensure that no important aspects are overlooked. Solar registers are a well-known example. For these registers, also known as solar atlases, complete localities are surveyed from above to check the suitability of buildings and land for the installation of solar systems. While factors such as the orientation of the house are evident from the building documents, current aerial photographs can provide evidence of previously unknown shading at different times of the day. Planning errors or miscalculations can be reduced or completely avoided thanks to modern drone technology.Contact us
What is a roof inspection?
Inspecting a roof aims to detect minor damage before it becomes a major problem. With a roof inspection using a drone, such an inventory can be carried out quickly and cost-effectively. The drone is used to capture images from various angles and, using our software, compile and evaluate them into an orthophoto or 3D model. Based on this evaluation, further steps for repair can then be planned. With our drone with up to 16x optical zoom and 48MP resolution, even the smallest damage can be detected. In addition, a thermal imaging camera can be used to inspect the roof for wet spots or leaks.
How much does a roof inspection cost?
Inspecting roofs with a drone can be done relatively quickly and inexpensively, even for large roofs or areas. The price depends on the area and the type of assessment, whether thermal images and a 3D model are needed. During a roof inspection, your roof can also be measured at the same time and this data can be used for the accurate planning of a photovoltaic system.
Which drone to use for a roof inspection?
We use an industry standard drone with 48MP camera with up to 16x optical zoom and high resolution thermal imaging camera. We take pictures from different perspectives, which are then processed into an orthophoto or 3D model using special software. This data can be used for further purposes, e.g. for a roof survey, planning of PV systems or repair work on the roof.
Which drone should be used for a roof survey?
A roof survey requires a drone with high resolution camera as well as GPS and additionally photogrammetry software. Photos of the roof are taken from different angles and processed in our software with high computing power to create an orthophoto or a 3D model. Based on this model, it is now possible to measure the roof surface precisely and to plan this data accurately for further work on the roof or the installation of a photovoltaic system.
Who does a roof inspection?
We at Bilddichte can take high-quality images of your roof with our drone at low cost and evaluate them with our special software. Especially flat roofs should be regularly checked visually and additionally with a thermal imaging camera. This way, even small damages can be detected and repaired at an early stage. A regular inspection can also serve as proof for your insurance company if damage occurs.
