I have an unused roof vent which used to serve a cooker extractor, what is the best way to seal this?
The 110mm plastic pipe emerges through the roof tiles via a lead pipe opening about 120mm wide, I have easy access to this as it is adjacent to a flat roof, at the moment it still has the 110mm pipe running down to the ceiling which has been blocked off and duck tape is wrapped around the vent at the top.
I want to make this more permanent and remove the 110mm pipe if possible but that leaves a 120mm lead pipe outlet, is there something that will fit over this securely or any other ideas?
