House Damp Issue

Hi All,

Hope you are well.

Posting for my neighbor whom is struggling to remedy a damp issue in an upstairs bedroom. Knocked on my door this morning to compare properties, so I took a look for him and found the below.

He has a persistent damp issue in the upstairs bedroom. This has been an issue for ~2 years and doesn't seem to have been resolved by chimney re-pointing he had done.

I examined the plaster and it still feels moist, so went into his attic and noticed that directly above the damp area is a wooden roof beam that looks wet. I suspect moisture is entering his roof, soaking into the wooden roof beam and down into the wall of the bedroom.

I also noticed a breeze entering the loft moving some of the white roofing membrane not seen in other areas of the loft - further suggesting a possible entry point via the roof.

Looking outside the property seems some staining down the sides of the roof adjoining the chimney - suggesting water is not being correctly ran into the guttering. Also the lead flashing image shows it covering a wire which seems odd.

If anyone has any thoughts / suggestions it would be a great help to him.

Thanks in advance!
