Survey guide
What's Included in a Roof Survey
A clear guide to what a flat roof survey covers, what you get in the report, what access we need and what happens next, so you know exactly what you're paying for.
Inspection scope
- Condition of the waterproofing layer: splits, blisters, ponding and failed laps
- Upstands, flashings, parapets, trims and rooflights
- Outlets, gutters and drainage falls
- Signs of deck movement or saturation
- Thermal imaging or core samples on invasive and leak detection surveys
What the report contains
You receive a digital report with annotated photos, the measured roof area, the cause of any leak we've found, and prioritised recommendations, from minor repairs to overlay or full replacement.
Access requirements
- Safe access to the roof. We bring ladders, and higher roofs may need a tower or hatch access
- Access inside where there is staining or a leak, so we can trace it
- Any drawings or previous guarantee paperwork you have
Next steps after your survey
If repairs or waterproofing are needed, we turn the report into an itemised quote. There's no obligation. The report is yours to keep and use with any contractor.
