I know someone here had problems immediately after a new roof, something that had been used poisoned a lot of plants. Like Ray says, I would let it "cure" for a while.
Other than that I've not heard of any problems with rain water. I use a "Rain Mix" fertiliser from Europe which is the same as MSU and when I have plenty of rain water I use it on everything with no problems. I only use tap water these days when I'm running short of rain water, then I save what's left for the sensitive plants.
