I had exactly the same experience.
Here where I live the winters are extremely dry, especially aound June/July (southern hemisphere). Two years ago my cousin who lives two blocks away from me took down his roof in winter knowing that he would not have to contend with rain. Ended up having his house completely flooded by unseasonal torrential rain.
A year later I am in a position where my roof needs replacing, so based on the law of averages I recon that there is absolutely no chance that we can have rain in June/July two years in a row, so off comes my roof.
I mean what are the odds right?
Had to open the house doors to prevent the water from damming up too high in the livingroom by midnight...
