I wasn't sure which section to post this, roofing or loft, so please move if needed.
We are in the middle of having our En-suite bathroom/shower redone.
When the builders removed the plaster boards they noticed the timber/beams at the top of the blocks as in the attached photos looking wet.
The wetness seems to run past the dividing walls at each end of the room, but obviously I can't see any further than those to see how far it runs along.
The plaster boards weren't wet or water stained when taken down, the marks on the ceiling are where the old plasterboard butted up against it.
The shower cubicle was on the opposite wall, so it wasn't under it. But under image 2, is where the extracted fan to the outside was.
The builders showed my that barrettes had not installed a tube/pipe that runs from the fan through the block, across the cavity and out through the brick, so all the moisture from the room, would have been going into the cavity wall.
Who would I get to come and inspect the loft to see what's causing it? A roofer, or loft survey company?
A few yeas ago, we had uPVC soffit and the fascia., the fascia was the cladding type which goes over the existent fascia.
This was done around 7 years ago, but it turned out to be a bit of a cowboy job, and we had to get it sorted, so I am wondering if it could be anything to do with that.
I've looked in the loft and the felting seems to be fine. I can see light coming up through the vent slots in the soffit, so the insulation isn't blocking them.
I haven't been able to get right over to it in the loft, as I'm 65, and not as flexible as I once was.
Our house is around 27/28 years old. (Barrets)
So, as I say, who would I need?
Images are numbered across the room 1 to 7.
Since I'm unable to upload all 7, I have linked them to one of my Imgur photo accounts.
Thanks for any replies.
