What needs to be clarified
The task could examine where moisture appears, whether episodes recur and how the proposed entry routes are supported. The visible stain location and the possible water entry point are distinguished; their coincidence should not be assumed without examination.
Materials to prepare
- House and roof plans, available junction drawings, the contract, material information and work records.
- Dated photographs and episode notes identifying the room, stain locations and weather circumstances.
- Repair and maintenance history, previous leak information and changes before and after interventions.
What to compare
- Whether marks recur in the same place and whether episodes have comparable observation conditions.
- How accessible junctions, penetrations and drainage elements relate spatially to the moisture signs.
- Which explanations are supported by inspection and records and which require further agreed checks.
Possible outcome of the analysis
A possible output is an area diagram and episode chronology, a list of recorded signs and reasons for further examination. For acceptance, a supported defect can be distinguished from a proposed specific cause.
Limits of the conclusions
A single stain cannot reliably establish the entire water route or extent of hidden damage. Roof access, opening construction and verification procedures require safe arrangements and separately agreed execution.
