What to do
- Record when leaks occur and where water appears.
- Do not climb onto an unsafe roof to investigate.
- Ask the roofer to trace likely routes through junctions, flashing and coverings.
Put it into your brief
Note the time, weather and position of each water mark. Share photographs taken safely from indoors or ground level, and mention any chimney, valley, window or extension near the affected area.
Make the comparison useful
Ask how the suspected entry point was checked. A proposal should distinguish a diagnosis from an assumption and explain whether internal water damage is included.
