I didn't mention in the post about the TV aerial the other day that the roof looked a bit uneven. Well it's been raining a lot today and it seems to have caused a bit of damage. The roof has fallen in.
It turns out that one of the beams has fallen apart either rotted or eaten by beasties. Lots of the others may be in a similar state. We were lucky with this fall in that the damage was in a bathroom, the false ceiling held and only small pieces hit the floor. It could just have well have come through and smashed up something expensive or fallen on me.
We are now looking at an enormous bill and massive disruption. I feel a little sick.
