Party Wall Notices and Roof Work on Terraced Houses
Roof work engages party wall procedure when it cuts into, builds off or otherwise affects a shared structure, and straightforward recovering of your own slope generally does not. Check where your own roof work sits under Party Wall Act, then book a survey to evidence it. On this page: Party wall · Party wall procedure · Recovering own slope.
Does the work cut into, build off, or otherwise affect shared structure?
- No — recovering your own slope Generally outside the procedure. Recovering a slope without touching shared structure does not usually engage it.
- Yes — cutting in, or a shared stack The procedure is engaged. Written notice on the adjoining owner within the statutory period; the adjoining owner consents, or dissents and appoints a surveyor.
- Only the scaffold crosses the boundary A separate question. Scaffolding over a neighbour's land needs their permission whether or not the party wall procedure applies.
This page is general information about how the rules apply, not legal advice. Confirm your own position with the authority named below before work starts. The authority here is a party wall surveyor.

Does roof work need a party wall notice?
Usually not. Recovering your own roof slope without touching shared structure generally falls outside the procedure. It becomes relevant when work cuts into a party wall, builds off it, or affects a shared chimney stack.
A party wall is a wall shared between two properties or standing on the boundary between them. Generally does not engage the procedure where the shared structure is untouched.
Which roof works engage the procedure?
Four situations engage it: cutting into a party wall to insert or bear a structural member, removing brickwork from shared structure, work to a chimney stack straddling the boundary, and excavation near an adjoining foundation.
- Inserting beams, forming openings or removing brickwork engages it.
- The requirement is written notice served on the adjoining owner within statutory periods.
What happens after a notice is served?
The adjoining owner consents, or dissents and appoints a surveyor. Where surveyors are appointed they agree an award recording the works and conditions, usually with a schedule of condition of the neighbouring property.
- The options of the adjoining owner are consent, dissent and appoint a surveyor, or dissent and appoint jointly.
- Scaffolding over a neighbour's land requires their permission separately.
Do you need permission for scaffolding over next door?
Yes. Placing scaffold on or over a neighbour's land requires their agreement, and that permission is separate from any party wall notice. Access is the practical issue that delays terraced roof work most often.
Recording the neighbour's property before work protects both parties. Continuous roofs cross ownerships even where the procedure is not engaged.
- Cutting into shared structure engages the party wall procedure.
What is a schedule of condition?
A schedule of condition is a dated photographic record of the adjoining property before work starts. It protects both owners by establishing what damage pre-existed, and it settles most disputes before they develop.
- Recovering your own slope generally does not engage it where shared structure is untouched.
- Scaffolding over a neighbour's land requires permission separately from any notice.
- A schedule of condition protects both parties.
A shared roof line is a practical matter even when it is not a legal one.
Working on a continuous terrace roof
Even where no notice is required, putting scaffold on a neighbour's land needs their agreement — the practical issue that actually delays jobs. The reassuring answer is the common one, and stating it plainly saves owners unnecessary cost and delay. Ownership on the ground is rarely that tidy. Where a terrace went up as municipal housing and was sold off house by house, one continuous roof line ends up above several separate owners, and access is agreed with each of them before a scaffold is designed. Roofers in Erdington meet that split ownership on most terraced streets, because much of the district's stock changed hands that way.
Getting the scope established
A schedule of condition protects the owner from claims as much as it protects the neighbour. On terraces, the stack straddling the boundary is what most often brings roof work into the procedure.

A party wall is one shared between two properties or standing on the boundary, and on a terrace it continues up through the roof — a chimney stack straddling the line is shared structure as much as the brickwork below it. Recovering your own slope without touching that structure generally falls outside the procedure. Cutting into it, building off it, forming an opening or working on a shared stack engages it, and written notice has to be served on the adjoining owner. Scaffolding over a neighbour's land is a separate permission and is needed either way.
