I live in a mid terrace house which is on a slope. The houses in the terrace are stepped up about 2 feet above each other. This means that there is about a 2 feet piece of wall between my (lower) neighbour's roof and my roof. The wall is my part of the house and means that the upper two feet of my loft wall is exposed to the elements.
I am going to have my roof renewed and I also want to have the wall re-rendered. When it is raining with the wind blowing hard on my wall, my neighbour has problems with some rain running down from the wall and into his loft. I don't know what the seal is between my wall and his roof - if it is flashing, or just a cement fillet at the base of the wall.
Who would be responsible for repairing the seal - my neighbour or myself?
I assume if it is just a cement fillet, then it would be repaired as part of the rendering work. If it is flashing, I don't know if it would or not.
My neighbour is happy to pay for the work to be done if it is his responsibility. Likewise, I'm quite happy to pay for it if it's my responsibility.
