I've had a constant build up of water in our extractor fan ducting in the loft. This has been made worse by a tear in the ducting causing a leak to spread.
There doesn't appear to be water dripping inside the loft from the outer edge of the pipe so I think the seal is secure holding the pipe in place.
For whatever reason the rain water is building up in the ducting. We no longer use the extractor fan therefore I'm pretty sure it must be external water (rain) building up.
I originally thought the external vent of the roof or the pipe exposed on the roof might be damaged causing rain water to enter the pipe and ducting. Now I think it might possibly be an inadequate vent cowl (I think that's what you call them!) that was replaced in a hurry by a roofer a year or so ago.
I've attached a picture of this and a link to the item I think the roofer bought at the time (a FloPlast ring seal soil vent ring terminal).
Does this look like the wrong type of weather proof fitting? If so, can anyone recommend something more suitable to withstand the wind and rain?
Many thanks
