What to check
- Map suspected water entry against the internal locations showing damage.
- Review the membrane, its laps, drainage outlets and upstands.
- Establish what is known about the deck and insulation.
- Examine previous repairs and the assessment of remaining roof life.
For the roof condition, proposed system and repair or replacement scope to discuss, see flat roofing.
Plan the next decision
Investigate the roof build-up before comparing repair, overlay and replacement proposals. Moisture beneath the surface can alter which option is suitable for the actual roof.
Define the approval authority, access conditions and required result for the roof package. Where safety, security or compliance is affected, use competent assessment supported by premises-specific information.
Records and follow-up
Link the survey findings, authorised work and completion evidence in the roof record. Keep unresolved recommendations visible with an accountable owner and required follow-up date.

Consult HSE workplace guidance for general context. Assess its relevance to the premises and check current requirements before relying on time-sensitive details.
Frequently asked questions
Can a leaking flat roof be repaired?
Sometimes a local defect can be repaired. A condition assessment should consider the wider covering, wet insulation and drainage before comparing a local repair with renewal.
What should a replacement quote include?
Ask about removing existing layers, insulation, outlets, edges and penetrations, roof access and disposal. Confirm how concealed defects would be handled.
