Hello, where our internal wall meets the ceiling (it's an outside wall on our bungalow) we have damp/wet patches right across. The gutters are clear and when I look in the loft I can see a hole in the roof liner above this area so I assume this is my issue but would one hole cause wet patches right along the wall? I plan to remove the tiles but thought I would ask if one hole could do this.
Thank you
Thank you
