Our vent, as you can see from this picture, stopped just under the roof in the loft. This, during the cold weather led to large amounts of condensation on the wooden boards that are the base of the roof and also explained the smell in the loft!
The solution to this problem is to feed the vent pipe through the roof and insulate the extra pipe in the roof. We decided to go for the "top hat" option, and quite a large one at that. This will give us space for air ducts from planned ventilation fans in the bathroom and toilet, both badly needed.
Our neighbour, The Real Farmer and also a joiner by trade, had offered to fit this for us as part of our continuous competances exchange policy (this time I paid by a complete re-install on his sons very sick computer). Rather him than me, especially on a cold Sunday in January.
If I'd done it we'd probably ended up with a hole in our roof for weeks,
but he completed the job in a couple of hours leaving for me to simply buy the neccesary pipe and fittings and install them
The pipe is now also insulated but still held up by a bit of rope, awaiting a more permanant installation when I install the ventillation for the bath and the toilet.
The roof is also looking a lot better now that it's dried out a bit, looks like we've caught it in time. Once it warms up a bit we'll paint a coat of anti mould on it and it should survive for many years to come.

Our waste vent goes straight up to the open air, and is not covered in any way. Hmmm... probably in line with not having a cover on the chimney pots, and using an old plastic bag as a temporary/permanent repair for broken tiles.
TOCO,
That's correct, It doesn't need to be covered. Our vent pipe is also open (it goes through the roof of the top hat and not under it). The most important thing is that it's insulated in the loft.
We could have gone for the single pipe through the roof option as well, but chose a "top hat" so that we could feed air vents from the bathroom and toilet up there as well (these need to be under the hat)
Interesting to learn about your fixing procedure...I think after all the dew and mold is done away with it again looks fresh and healthy and safe.
