Watermark on rafter

[huwy123]

Whilst in the loft today I have noticed there is a strong water mark on a rafter. It feels wet to touch and checking with a moisture detector confirms its wet.

The rafter would appear to be immediately adjacent to our loft conversion (3.5 years old now). I will contact the loft conversion company who will hopefully look at it but in the mean time I was curious to where the problem is likely to lie and how to fix it.

Thanks in advance for any help.

Probably localised flooding looking at the photo of the roof.

I'd say the guttering would be better off reversed with a downpipe into the other gutter.

Thanks for the advice. I'm thinking this is going to be a difficult one

Gutter discharging towards roof seems illogical as it could force it under the tile.
