Rooftops & sheds
Roof sheeting, ridges and gutters, penetrations, rooftop solar arrays and drainage paths on industrial buildings and warehouses.
Asset & infrastructure inspection
Look at the asset without sending people up the ladder
Drone-based visual and thermal inspection of rooftops, structures and industrial assets, returning georeferenced imagery, a 3D model and a defect list rather than a folder of photographs.
Scope
What we can inspect
Any asset that can be seen from above or from a safe stand-off distance is a candidate for a drone inspection. Typical scopes include:
Towers & masts
Structural members, corrosion and coating breakdown, bolts, insulators and attachments, documented from multiple angles without a climbing team.
Industrial structures
Silos, stacks, conveyors, pipe racks, cooling towers and storage tanks — condition surveys that would otherwise need scaffolding or rope access.
Thermal surveys of equipment
Electrical and mechanical hot spots on exposed equipment, where a temperature anomaly indicates a fault before it becomes a failure.
Corridors & rights of way
Vegetation encroachment, access track condition and structure locations along linear assets, delivered as mapped imagery.
Site progress & documentation
Periodic aerial documentation of construction or rehabilitation progress, captured consistently between visits so change is comparable.
Method
Imagery becomes an asset register, not an album
-
Define what a defect looks like
Inspection criteria and severity bands are agreed with your maintenance team before flying, so results are graded consistently with your existing standards.
-
Plan and fly the coverage
Overlapping visual and thermal capture at the stand-off distance needed for the required level of detail, with geotagged frames throughout.
-
Build the model and orthomosaic
Photogrammetric processing produces a 3D model and orthomosaic, so any image can be traced back to its exact position on the asset.
-
Log, grade and report
Each finding is listed with position, description, severity, image reference and a recommended action, then delivered with the model and image set.
Deliverables
What you get back
- Geotagged image set organised by asset, elevation or inspection zone.
- 3D model and orthomosaic for measurement, mapping and future comparison.
- Defect register with coordinates, severity, description and recommended action.
- Annotated imagery for the findings that need maintenance attention.
- Thermal image set where thermal inspection is in scope.
- Summary report with method, limitations and a prioritised action list.
Inspection questions
Common questions
Do we need to shut down the plant or the asset?
In most cases no. Visual inspection is flown while operations continue. Thermal inspection of equipment needs the equipment in a representative operating state so that temperature differences are visible; any isolation requirement is agreed in advance with your safety team.
How close can you get to the structure?
Close enough to resolve defects at the scale your maintenance team needs, while respecting the safe stand-off distance for the structure, wind conditions and site rules. Where access is restricted, higher-resolution optics are used instead of flying closer.
Can results be compared with the next inspection?
Yes. Repeat inspections are flown on the same control and coverage plan, so imagery and findings line up position for position and deterioration can be tracked rather than re-discovered.
Have an asset that is hard to reach?
Describe the structure and what you need to know about it. We will confirm whether a drone inspection can replace the access method you are using today.
