I reported damp prior to the storms and asked someone to check the roof. I would be concerned that this would affect our building insurance claims, but the man from GHA who came to check told me there was no damp, so I guess we go with that and put the claim in secure in the knowledge that we checked it out recently.
The fact that he refused to go into the loft is immaterial for the claim, but could well explain why we now have water damage to our flat, and to next door's flat. Who knows what damage might have been saved with new blooming nails in those loose tiles.
They really are useless.
