I noticed that one set of wooden beams in the loft of my house were wet at the top/apex (looks like water has been running down to about half way down the beam).
There is also moisture (looks like condensation) on the plastic roof lining.
Just below this area is the top of the soil pipe which stops just below the top beam without going through the roof.
Looking from outside, there is a gap in the mortar below one of the capping(?) tiles at the rear side - at first I thought that this might be a problem & I'd have to get it filled in but now I know the situation with the soil pipe, I guess it could be a vent.
Could the moisture be caused by the soil pipe or is it more likely to be a leak from the gap in the mortar?
Most of the houses here (built around 1990) are 1 or 2 bed semi's or terraces and I've noticed that the 2 beds have what looks like a vent about half way up the roof whereas the 1 beds (like mine) do not (I haven't been able to look at the back of any of them to see if they have a gap in the mortar like mine has).
I always though that soil pipe vents had to go to the outside air - is this type of positioning of a soil pipe allowed?
