Hi all, found what looks like the begginings of a flat roof vent installation on bungalow extension. Just had a piece of slate and bricks on top. Thing is I can't find any info on the grommet/seal used and not sure how to finish it off. Felt all inside and doesn't seem to be any water ingress but am a bit baffled. Doesn't seem right to just stick a 110mm pipe and a mushroom vent in it. Any advice greatly appreciated chaps (or chapettes)

Look like an old boiler flue vent to me.
Pull the rubber up to a point.

Thanks for the reply catlad. Not sure what you mean by "pull the rubber to a point". The diameter of the inside rim excluding rubber is about 130-140mm but think it would be a job squeezing a 140mm pipe in. Even a 110mm pipe plus vent fitted in it wouldn't fill me with confidence. Reckon I might try and find a large inside diameter vent and trim the rubber of I have to. More head scratching me thinks
