What's actually in a drone roof report?
A proper drone roof report is a structured document — annotated photographs organised by roof face, a defect log with locations and severity, measurements where they matter, and condition notes a roofer or insurer can act on. It is not forty unlabelled JPEGs in a WeTransfer link. Both get sold as “a drone roof survey”, and the price difference between them is smaller than you’d think, which is exactly why it pays to know what you’re ordering.
Here’s what a good one contains, section by section.
1. The summary page
One page up front: property address, survey date, weather conditions, overall roof condition in two or three sentences, and a ranked list of anything that needs attention. If you read nothing else, this page should tell you whether to relax, budget, or phone a roofer this week.
Survey date and weather matter more than they look. Wet slates photograph like damaged slates, and an insurer reading the report will want to know the conditions it was shot in.
2. Methodology and credentials
A short section stating who flew, under what qualification (typically a GVC with an Operational Authorisation for residential streets), the CAA Operator ID, insurance details, and the kit used. This is the part that makes the report usable as evidence — for an insurance claim, a property purchase, or a dispute with a builder. A report with no named pilot and no credentials is just pictures.
3. Imagery, organised by elevation
The core of the report: high-resolution stills of every roof face, worked through systematically — front elevation, rear, each hip or valley, ridge lines, chimneys, flashings, gutters, and any flat sections. Overview shots establish context; close-ups capture detail down to individual tiles, mortar joints and lead work.
Two things separate good from lazy here:
- Coverage is systematic, not selective. Every face appears, including the boring ones. “No defects observed on the rear elevation” is a finding, and it’s one you’ll want in writing if a roofer later claims the whole roof needs stripping.
- Images are annotated. Arrows, boxes and captions on the photographs themselves — “slipped tile, third course below ridge”, “open mortar joint, left chimney haunching”. You shouldn’t need the pilot on the phone to interpret their own pictures.
4. The defect log
A table that lists every issue found, where it is, how bad it is, and — in better reports — what to do about it. A typical row: location (elevation and position), description, severity (usually a three- or four-point scale from cosmetic to urgent), and a recommendation such as “monitor”, “repair within 12 months” or “refer to roofing contractor now”.
This table is the part you’ll actually forward to people. A roofer can price from it; an insurer can assess from it; a buyer can renegotiate from it.
5. Measurements, where they earn their place
Most house reports don’t need survey-grade accuracy, but useful numbers often appear: approximate roof areas per face (handy for re-roofing quotes), ridge and gutter lengths, chimney dimensions. For re-roofing and solar-installation jobs, some pilots produce a simple roof plan or orthomosaic — a scaled, top-down composite image — as an extra deliverable. If you need contractor-grade measurements, say so when you request quotes, because it changes the flight plan and the price.
6. The optional extras
Thermal imaging is the big one: a radiometric thermal camera flown over the same roof can show damp ingress, missing or slumped insulation, and leaking heating pipes — problems invisible in ordinary photographs. It typically adds £100–£250 to a roof job and produces its own annotated section in the report. Worth it when you suspect a leak you can’t trace; overkill for a pre-purchase once-over. There’s more on what thermal can and can’t see on our thermal survey page.
Video flythroughs look impressive and are occasionally useful for showing a contractor an access problem. As evidence, stills beat video — insist on the stills either way.
Raw image files. Ask for them. It’s your roof; a pilot confident in their work hands the originals over without fuss.
What a roof report is not
It’s evidence, not judgement. A drone report replaces the ladder and the scaffold tower — it doesn’t replace the roofer’s opinion on whether that cracked flashing needs lead or sealant. What it does is make that opinion cheaper and better: a roofer quoting from systematic photographs quotes the actual problem, not the worst case they can’t see. We’ve covered the scaffolding-versus-drone economics in Drone survey vs scaffolding: the £1,000 question.
Red flags when you’re comparing quotes
- “Photo pack” with no report — fine if that’s all you want, but know that’s what you’re buying.
- No annotations and no defect log — you’re paying to do the analysis yourself.
- No credentials section — no Operator ID, no insurance details, no named pilot. Useless for insurance, and a hint about the operation generally.
- Watermarked or withheld originals — your report, your images.
- A price that doubles once “report writing” is added on site. The quote should name the deliverables up front.
The fix for all five is the same: ask what’s in the report before you book, in writing. Typical pricing for the whole job — survey plus a proper report — runs £150–£400 for an ordinary house, with the moving parts broken down in Drone roof survey costs: what you’ll actually pay.
Or skip straight to comparing: post your roof on our drone roof survey page and up to 4 CAA-certified, insured pilots covering your postcode will quote, deliverables named. Free, no obligation — and you’ll know exactly which kind of report you’re being offered before anyone takes off.
