The affected roof area changes the likely access and repair questions
Start with the room and elevation beneath the visible sign, then note dormers, rooflights, valleys, chimneys or lower additions nearby. Converted properties may also have different ownership or access arrangements by floor. A simple annotated exterior photograph can make the relationship clearer without requiring roof access.
- Use front, rear and side labels consistently.
- Mark the affected room on a simple plan.
- Distinguish shared and private roof sections where known.
