Gap in attic - fire hazzard

davepower1983

Hi our house is a 12 year old terraced council house.
While up in the attic I noticed the wall/plasterboard did not run flush to roof at the tighest point. The gap is approx 8 inch at the front and back. I was able to push a 4ft pole in which I assume is going straight in to the neighbours attic.
I was told this is a firewall and their should be no gaps and is a fire hazard.

Any thoughts or feedback

There shouldn't be a gap. Are you a council tenant? If so get on to them tomorrow about the issue.

1000% a fire hazard and should be remedied immediately.

How would this gap be rectified? Is the block work to go right to the roofline. The insulation too . Also would you tape the insulation to the roof felt.

Is the shared felt and tile supports not also a fire hazard.

Basically is anything with a shared roofline not a hazard?

Along the full width of the wall.

Pack that stuff in tight.

Not for me. Mines a detached bungalow. Just for interest in how they do it.

On a block party wall I usually see the blockwork brought up as tight to the felt as possible, usually with some parging to follow the roof slope. Any gaps are then stuffed with mineral wool.
The better the parging the less need for mineral wool
