We had trees cut down, with permission, after some high winds just blew a branch and just missed my neighbours shed, so, we took them down and after the next high wind I went out to feed the chickens and saw our 2 chimney pots on the wobble!!! it was a bank holiday so we called the fire brigade out, thankfully they did not fall onto the roof etc like a house down the road had, that appeared to take ages to get fixed again. Chimney pots often come loose due to the pull of a fire etc, they shrink the cement from heat then cold and 2 pots one hot one cold (I am talking rubbish but hope you understand) so now that's done, never got our Ariel put back so we use indoor aerials, also the neighbours fence fell on our car, I never claimed for that one, they had a lot of ridge tiles off too.....I think they were 80mph winds....
