A roof plan seen from above, with the drone flight orbit drawn around it A hipped roof plan drawn in plan view: eaves, hips, ridge, chimney and two rooflights, with a dashed flight orbit around the building, four drone positions, camera cones falling on the roof and a scatter of point-cloud dots across the roof surface. FIG. 01 — ROOF PLAN POINT CLOUD FLIGHT ORBIT N NOT TO SCALE
The plan is the roof; the orbit is the flight; the dots are the cloud.

01 / Why drone

No scaffolding.
No cherry pickers.
Nobody at height.

A drone reaches roof slopes, gutters and elevations that would otherwise need access equipment — reducing cost, disruption and risk on the way in. The capture is CAA-licensed; the reporting is Chartered Surveyor.

  • 01

    Access

    Roof slopes, gutters and elevations that would otherwise need scaffolding or a cherry picker — reached in a single visit, on one roof or a hundred.

  • 02

    Safety

    The inspection happens from the air. No working at height, no access equipment standing on site, far less disruption to whoever is using the building.

  • 03

    Record

    You keep the evidence, not just the opinion: imagery, video and measured data you can return to, re-measure and hand to a contractor later.

02 / Key services

Four ways we capture
building intelligence.

Whether it's a single roof or a portfolio of properties, we combine Chartered Surveyor reporting with drone capture, photogrammetry and laser-accurate point cloud data.

  1. 01

    Roof Reports

    Chartered Surveyor roof condition reports and defect assessments. Clear, professional documentation for insurance, maintenance planning and Schedule of Condition.

    You receive clear, actionable documentation — with support interpreting the findings.

05 / Our work

Real projects,
real outcomes.

Fire, flood and escape of water are a significant part of the work — capturing damage as measurable data so insurers and loss adjusters can settle without everyone standing in the wreckage.

06 / What clients say

I have been working with Gary and the Rotorgraph team for around five years, preparing roof inspection reports and undertaking other surveying-related work. The drone images, videos and models that Gary provides are excellent and help me to prepare accurate reports.
