Identifying where damp is coming from

Question

I’m looking for someone to advise where the damp is coming from and if work is needed to rectify problem. It may be coming from the attic where the extractor fan pipe from the bathroom lies. The damp is along a bedroom ceiling where it joins the wall above a window in an 8yr old house.

Hi firstly it is not damp but condensation probably due to you felt having perished in your eaves which in turn leads to rain water blowing back onto the wall plate under you roof tile s/slates thus causing a cold spot which hits the warmth of the bedroom and thus causing condensation (black spots )any further questions ring me cheers Dylan Gibbs Gibbs General Builders Porth

The ventillation pipe will be badly installed, small job to rectify if this is the case, would need pictures in the attic to give you a straight answer.

Gutters pointing slates etc

Sounds like condensation, a site visit would need to be completed

Andy · Answer

It could be for different reasons, broken tiles, ventilation issue, faulty pipe, repointing brickwork etc, the best idea is to have someone have a close up inspection of the whole area to assess the issue.

There can be a number of reasons, you need a specialist out, could be a roof tile come loose or the gutters along the top leaking or then as you say your extractor but I would say it needs someone coming out who is reliable and will take his time taking a look to get to the source of the problem.
