Start a drone survey business: measured roofs, site maps and 3D models
A roofer pays for scaffold just to quote, a solar installer sends someone up to measure, a builder guesses the spoil on site. A ten-minute drone flight and free photogrammetry software answer all three with a measurable map, a 3D roof model and the true area of every plane. Pick the right drone, then build the deliverable, the quote and the messages that win your first jobs.
- Roof measurements clients use: pitch, true area and findings in a ready-made template
- A business kit: quote calculator, price list, outreach messages, checklist and a 30-day plan
- A sub-250g camera drone: DJI Mini 4 Pro (around £600) with its standard batteries, plus two spares
- A PC with 16GB RAM and 100GB free disk for WebODM (enough for about 250 photos)
- Basic drone flying skills. Practise on your own land before any paid job
- Python 3 for the planner scripts. New to the terminal? Terminal survival kit
- About 6 hours a week to start: flying, processing and outreach
Who pays for drone surveys, and what they buy
Sell a measurement or a decision, not drone footage. That's what makes this a survey business.
Pretty aerial video is a crowded market. Measurements are notThe customers below don't care about the drone. They care about a number they can quote from, a photo that shows the problem, or a map they can hand to their client. You sell that, and the drone is just how you get it.
- Roofers: photos of every roof face and the true area of each plane, so they can quote without a ladder or scaffold visit.
- Solar installers: roof planes with pitch, orientation and obstructions (chimneys, vents, skylights) so the panel layout is designed before the site visit.
- Estate agents, letting agents and property managers: roof condition checks before a listing, at the end of a tenancy, or after a storm.
- Builders, groundworkers and landscapers: a measured site map, a height model and stockpile volumes, flown again every month as a progress record.
- Surveyors and architects: an orthophoto and a 3D model as a base for their own drawings. They do the professional sign-off, you supply the data.
- Farms and estates: field maps, drainage problems and storm damage across land nobody wants to walk.
What you deliverFour outputs cover nearly every job. An orthophoto: a top-down map stitched from hundreds of photos and corrected so you can measure on it. A DSM (digital surface model): the height of every point, roofs and trees included. A 3D textured model you can spin round in a browser. And a short written summary: measurements, findings with photo references, and the limits of the survey. Software builds the first three. You add the judgement.
Careful- What it takes. Capital: around £700 to £1,000 for a starter kit (drone, spare batteries, landing pad, filters), plus insurance at a few hundred pounds a year. A pro mapping drone for larger sites is around £4,000, so start small and upgrade when jobs need it.
- Paperwork: free Flyer ID, Operator ID at around £12 a year, commercial drone insurance.
- Skills: steady manual flying, a methodical safety routine, and comfort with a PC for processing.
- Hours: a typical roof job is 4 to 5 hours door to door, including travel, processing and writing up.
- Time to first customer: commonly a few weeks of outreach after your first free jobs.
- Weather cancels flights: plan around it.
- Who this suits: someone practical and tidy who likes doing a job properly, enjoys flying, and is happy talking to tradespeople. Roofers, builders, surveyors and photographers already have the contacts and add this as a second income.
