Drone roof inspection in Holsworthy

Holsworthy itself is a modest market town, but the real weight of the local housing stock sits out in the surrounding parishes, where working farms, barns and agricultural sheds make up a very large share of the roofs that actually need looking at. Getting a scaffold lorry to one of these properties often means a farm track rather than a made-up road, and a lot of those tracks were built for a tractor, not for a vehicle loaded with poles and boards.

The ground itself works against conventional access for a good part of the year. Holsworthy sits on the Culm Measures plateau, on heavy clay that holds water badly, and a wet winter turns a farm track or a yard into something plant machinery struggles with. A scaffold job booked for a damp week can simply become undoable on site, whatever was agreed in advance, which is a poor position to be in when a roof problem is not going to wait for drier ground.

Even where access is physically possible, a working farm is not an easy place to put a scaffold tower up regardless. Yards are in daily use, livestock movement does not stop for construction plant, and a structure left standing for the length of a scaffold job is one more thing to work around in the middle of ordinary farm work.

A drone survey removes the track and the yard from the equation entirely, because nothing needs to drive down either of them. The aircraft launches from whatever firm patch of ground is available near the farm, whatever the state of the lane leading in, and flies straight to the roof without needing the ground beneath it to hold any weight at all.

For agricultural buildings, that matters practically as well as technically. The Mavic 4 Pro's 100 megapixel Hasselblad camera and 6K video give a clear look at corrugated metal and fibre cement roofing on barns and sheds, where fixings and laps are usually the actual concern, and the Mavic 2 Enterprise Advanced's thermal camera can pick out where a covering has failed and water is getting into stored feed or equipment below.

The plateau is open to the Atlantic with nothing between it and the coast, so it is persistently wet and windy through the year, but for most farms and cottages here, reaching the roof at all without churning up a yard or a track is usually the harder half of the job, whatever the weather is doing on top of it.

Sam Hembury flies the survey and writes the report from a construction background, which means farm buildings get read the way a builder would read them rather than treated as a generic checklist. It lands within 48 hours, and the price is fixed and agreed before the flight, whether the roof in question is a farmhouse, a barn or a shed.

The operation holds CAA registration, Operator ID and Flyer ID, an A2 Certificate of Competency, and full Coverdrone insurance for commercial work across the Holsworthy area. No lorry has to negotiate a farm track, and no plant has to cross a wet yard, to get a proper answer on roof condition.
