In short
Possibly. The Party Wall etc. Act 1996 covers cutting into an adjoining owner's wall to insert a flashing, and work on shared walls and chimneys. Where it applies you must tell your neighbour before the work starts. Replacing a flashing in your own wall is not usually a party wall matter.
This is a job for our Chimneys, Leadwork & Flashing service.
What the Act covers
Section 2 of the Party Wall etc. Act 1996 lists the work a building owner may carry out on a party structure, and it includes cutting into the wall of an adjoining owner's building to insert a flashing or other weather-proofing. The government guidance is plain that you must tell your neighbours if you want to carry out building work near or on a shared boundary or party wall.
Where roofers meet it
- A shared chimney stack between two semi-detached or terraced houses.
- An extension roof abutting the neighbour's house wall, where the flashing is tucked into their brickwork.
- A parapet or party wall that rises above the roof line.
What to do
Talk to your neighbour early. If the Act applies, notice has to be served before the work starts, and the government guidance explains how to reach an agreement. A party wall agreement is separate from planning permission and building regulations.
What we do
When we quote chimney or flashing work we point out where it touches a neighbour's wall, so you can sort the paperwork before we arrive.
