We have an avenue of huge trees in a raised bank running about 40-50 feet from and parallel with the fron of the house.
They are well maintained and as the road and trees run roughly East-West. I assume that the trees, if they fall will fall with the prevailing wind, which is a westerly.
Luckily most of the trees outside our house have been replaced in the 25 years, so are less likely to come down and will not reach the house, but there is one huge tree.
Our house is long and thin, one room deep, so there is nowhere to hide, except downstairs. However, since we bought the house we have had all the chimneys repointed and two were rebuilt and we have been completely reroofed, so all we can do is lookout the insurance policy, put the insurer on speed dial, charge up the mobile phone and hope for the best!
