Neighbours extension terraced house party wall parapet gutter

Hi, I wondered if you would be able to provide me with some advice about the work my neighbour is proposing? We live in a middle terraced house and have a rear extension with a wall our side of the boundary, about 3 inches in from the boundary, with a flat roof and the fascia and guttering all tucked inside our boundary. The downpipe from the main roof also joins the guttering around this flat roof and it all goes to one soakaway. However, the neighbours want to build up to the boundary and then fill the gap with insulation, seal it off and put a parapet gutter on top of this wall making it a party wall. We believe this will fall below our fascia board on our flat roof as their roof is to be pitched. We are concerned with the potential damp this could cause. If we say no they made it clear they will leaving a small gap between the properties (we have a rendered wall which would then no longer be accessible for repair and maintenance). Are either of these ideas better than the other and do we have any rights to stop this from happening? Edit - I have already sought advice from the local council who are unfortunately not very helpful! Many thanks in advance.
