Lead flashing - to neighbours when inch gap between houses

[fairy]

House used to be end house, however early 1900s a house was built next door leaving an inch gap inbetween.

Looking to have roof renewed and roofer wants to lead onto firewall which is on next doors house.....told us it is ok to do that for weathering... not sure how we stand...any advice welcome.

No. Dont touch next door without permission from your neighbour(s).

Read up on all the recent past posts ref. the Party Wall Act and its possible consequencies.

Maybe the "inch gap" that you refer to is the cavity? Perhaps post a couple of pics?

The inch gap is literally a gap between 2 terrace houses where the houses were built independently. You have to look closely to even notice it. Though the houses are slightly staggered, so their firewall is higher one end of the house and lower at the other.. Guess they wouldn't build like that now.

Previously the gap had been closed with triangular tiles.....roofer wants to lead the gap saying it is allowed to weather proof the house.....

The act says:

53 What can be done to weather proof a narrow gap formed where a person is building on his own land alongside the Adjoining Owner's external wall (e.g. an earlier back garden extension built up to his side of the boundary line?
It is good practice to prevent debris collecting in (or animals entering) the small gap between two adjacent independent structures. There are several proprietary products that can effectively seal the gap between two buildings without having to cut into or permanently fix to either building. The Building Owner erecting the second structure would usually carry out this work.


However not sure how this fits with leading onto the firewall of the adjacent property..... any advice welcome

If the gap where your roof abuts his wall is closed at present with tiles then closing it with lead would be better. That said you should get permission from your neighbour before you touch his wall, and fitting a lead flashing (properly) will mean running a chase into his wall to lap the lead into.
