It looks like our upstairs neighbours are going to do a loft extension - as we are currently partly responsible for the roof, does this mean they will take full responsibility (ie cost) of doing it?
Do you mean the new roof? (yes). Or do you mean going forward (presumably the deeds will stay the same and you'll still be liable, in which case you'd want to make sure it wasn't shoddy!).
