Record the room, first appearance and changes after rain or water use. Photograph context and detail without opening walls. Water may travel before appearing.

Supply leaks and water ingress require different investigations. Relationships with rain, consumption and use are useful but do not prove a cause.

Painting may hide the mark without treating the source. Residual moisture, condensation and active ingress need different assessments.

Access, installation size, testing and documentation affect the work. Ask what investigation includes and whether repair is priced separately.

Surface, preparation, proposed system, details, outlets, protection, exclusions and maintenance. Clarify additional work and finishes.

Provide access and authorisation information. Gather plans and earlier work records. Do not access the roof to take photographs; safe access needs assessment.

Coordinate management, owners and occupants to authorise access. Record the issue without assigning responsibility from the position of water.

Identify the responsible person, site, operating periods and affected areas. Provide safety requirements, authorisations and approval processes for additional work.

A record may document agreed observations, methods, limitations and recommendations. It does not guarantee acceptance by an insurer.
