Party walls and boundaries
A valley gutter serves two roofs on two titles. Can the survey of one house decide the neighbour's duty to clear it?
No, the survey of one house cannot decide the neighbour's duty to clear a valley gutter that serves two roofs on two titles. The surveyor can describe the valley as seen from this side: debris, staining, or a view that stopped at the party line. Duty, access and who must clear it are not decided by that description. One inspection does not bind the neighbour and does not split the job. The solicitor is the person who takes the title and the duty. The survey does not.

What is the fuller explanation?
A shared valley is an easy place to over-claim. You can see leaves, and you can see that the gutter sits between two roofs. You cannot, from this house alone, decide that the neighbour must clear it, pay for it, or allow ladders on their side. The report should stay with condition and with the limit of the view. If the far slope was not entered, say so. Do not convert a blocked-looking valley into a legal obligation written against next door.
Show the solicitor the valley note and the two titles, and ask them what, if anything, the deeds or the arrangement say about maintenance. Do not send the neighbour a letter that pretends the survey has already decided their duty. A roofer pricing a clear-out from this side is pricing access they may not have. The home survey has described a gutter that serves two roofs. It has not appointed the neighbour.
What should you ask your surveyor?
- How much of the valley could you see from this house only?
- Did you describe condition, rather than the neighbour's duty to clear it?
- What should the solicitor be shown beside this valley note?
What are the typical next steps?
- Read the valley note as condition from this side only.
- Ask the solicitor who, if anyone, must clear a gutter on two titles.
- Do not tell the neighbour the survey has decided their duty.

Also asked about this
If leaves are only on the neighbour's half, is their duty proved?
No. Leaves on one half describe what was seen. They do not decide whose job it is to clear a valley that serves two titles.
Can you clear the whole valley because the survey rated it?
Not on the survey's authority. A rating, if there is one, is about condition. It does not give you the neighbour's roof to work on.
