Age and type of house
In this bungalow the living-room ceiling is the underside of the roof. Why does a stain there matter more to daily use than the same stain in an empty loft?
The stain matters more to daily use because this living-room ceiling is the underside of the roof, so the mark is in the room you occupy. There is no empty loft between you and the covering. The same stain in an unused roof void sits above a ceiling you do not live under. Here, water, staining and cold meet the sofa. The survey has recorded that stain on the occupied soffit. It has not, from the mark alone, decided whether the cause is a leak or condensation.

What is the fuller explanation?
In this bungalow the roof structure is the ceiling structure. Insulation, felt and tiles are immediately above the plaster. A loft stain can sometimes be left while you think. A stain on the living-room ceiling cannot, because it is the finish of the room. That is a practical difference, not a claim that every bungalow stain is a failed tile. The survey can map the mark. It cannot see the covering from the underside in enough detail to name the mechanism without a proper look at the roof.
Ask for the roof covering over this room to be considered with the stain, and keep that pair together when you speak to a roofer. Tell your solicitor the ceiling is the roof soffit, so this is not a remote loft mark. Do not repaint it and call the cause closed. The home survey has not tested the covering and has not ruled condensation in or out. Daily use is why the location matters. It is not itself the diagnosis.
What should you ask your surveyor?
- Is the stained ceiling the underside of the roof, with no loft void above it?
- Did you see the covering over that room from outside or from a hatch?
- Have you left leak versus condensation undecided?
What are the typical next steps?
- Treat the stain as being in the living room, not in an empty loft.
- Look at the roof covering over that room together with the stain.
- Do not paint over the mark and treat the cause as settled.

If the stain is small, is it only condensation and harmless?
Not decided. A small stain can be condensation or a limited leak. The survey has not separated those causes. The point is that the mark is on the ceiling you use, because that ceiling is the roof. The mark is on the ceiling you use, which is why daily use changes.
Does an empty cupboard in the same bungalow change the point?
No. The question is this living-room ceiling, which is the underside of the roof. Another cupboard does not put a loft between you and the covering over the room you sit in. That cupboard does not insert a loft over the living room.
