Visual condition reporting from RGB imagery — slipped or cracked tiles, flashing, gutters, chimneys, membrane condition — without scaffold, ladders, or access equipment.
RGB ONLYEvery finding in every report follows the same structure — location, frame reference, affected area, confidence, probable cause and recommended action, rated Red / Amber / Green. Here's a worked (illustrative) example from this survey type.
| Location | Main roof plane, both principal pitches |
| Frame reference | DJI_0490 (representative) |
| Estimated affected area | Widespread across fastener rows and side-laps; not precisely estimable |
| Confidence | Moderate–High |
| Severity rating (RAG) | AMBER |
Observation: A consistent pattern of rust-coloured bleed staining is visible at fastener heads, washers and sheet side-lap joints across the majority of the roof, corroborated across dozens of overlapping frames.
Probable cause: On balance of probability, corrosion of ageing steel fasteners and washers, consistent with a roof of its apparent age.
Recommended action: Recommend a close-access fastener and lap condition check to rule out perforation, and re-fixing as routine planned maintenance.
Every finding on every survey type is rated against the same published definitions, so a Red on one job means the same thing as a Red on the next.
