bedroom window wall moist/wet

[ash1212002]

Hi all

2 bedroom terraced house

The upstairs rear bedroom where the window is located the wall below the window the wall seems moist/wet I have also noticed it to be moist/wet on the right hand side of the wall, the wallpaper seems to be coming away

Was thinking it could be damp or condensation

Any suggestions what it could be? has only occurred recently during the cold weather and when it has been raining

4 months ago fitted laminate flooring, the room has central heating located on another wall

Shall get the ladder up on the weekend and check the roof guttering, exterior brickwork

Any other suggestions for what I should look out for when I get up on the ladder to check?

Cheers

Check for any loose or broken slates, whilst your up there, any copings on the gable? Check them too for movement and pointing.
Do you have any furniture on these walls and dry any wet/damp washing on the rads in the room?

Cheers will check the copings on the gable

no furniture on the walls and no washed clothes are put on the radiators
