Sitting here, working away, when I hear a drip, drip, drip. Looking up I see the wallpaper I have peeled back (where the mushrooms were - passim) is dripping. Getting on a step I see the wall is saturated.
Go into loft and see a rafter (from the apex ?) is wet halfway down. It was dry last year when I checked for the previous leak.
Looking outside I see where the valley/gulley meets the tiles a tile is out of position.
Of course it's forecast to rain till midnight ...
