Hi,
I have a sloping internal roof in my shower room with a Velux window and an extractor fan with a delay fitted to the lighting circuit but I have still been having problems with damp in the room. I removed the extractor fan from the sloping ceiling as it was rattling a treat and replaced it with a new one from Wickes. This worked fine for about 2 months then went the same way as the old one.
I've just removed the fan and had a look to find that not only is there no pipe taking the damp air away but that there has been a nice big hole cut in the roofing membrane to allow the condensation to find its own way out past the concrete roofing tiles.
What is going to be the best way to fix this problem? I was thinking getting a vent tile put in and running a bit of 100mm flexible ducting to it from the back of the fan, only problem being that as the distance from inner ceiling to back of tiles is only about 40cm there is no room for a kink in the pipe to stop condensation running back into the bathroom.
There is a vertical outside wall in the room but it's so low (about waist height) that I wasn't sure it would be any use, and I'd also end up with a big hole in my ceiling!
Any help gratefully received, I can do a noddy diagram if that might help!
Thanks
