Roof works can range from replacing a few tiles to completely changing the shape and structure of a building.
So, when does a roof alteration become a Party Wall matter?
The important point is that repairing or altering a roof does not automatically require a Party Wall Notice. What matters is whether the work affects a party wall, party structure or otherwise falls within the scope of the Party Wall etc. Act 1996.
Straightforward roof repairs
Routine works such as replacing tiles, renewing flashings or repairing gutters will not normally require Party Wall procedures merely because the properties are attached.
However, care may still be needed where work affects shared roof details or requires access to neighbouring land.
Raising a party wall
Party Wall issues commonly arise where roof alterations involve raising a party wall.
This can occur with:
- loft extensions;
- mansard extensions;
- roof terraces;
- parapet alterations; and
- major roof remodelling.
Where the existing party wall needs to be raised or otherwise structurally altered, notice may be required.
Cutting structural members into the party wall
Roof projects often require new steel beams.
If beams are inserted into a party wall to support a new roof or loft structure, this can fall within the Act.
Structural drawings should therefore be reviewed before work begins.
Dormers and roof extensions
A dormer itself does not necessarily require a Party Wall Notice.
However, the structure supporting it may.
A loft conversion involving steel beams, raised party walls or other structural work may trigger the Act even though much of the visible construction takes place within the roof.
What about detached properties?
Being detached does not automatically mean the Party Wall Act is irrelevant.
Deep excavation near a neighbouring building can also fall within the Act, so projects involving substantial structural additions should still be considered carefully.
