Joe,
My roof is made of asphalt shingles and I've been using rainwater from that
roof for several years on my CPs with no ill effects that I can tell.
Occasionally when it has been dry for a long time I throw out the first
bucketful of rain I catch in the theory that this contains all the built-up
toxins washed off of the roof, but I'm not sure if this is necessary.

I have used water that is a couple of months old. The mosquitoes are fierce
here and if I don't put a lid on my water buckets right after it rains I get
lots of mosquito larva in them. One way to deal with this is to put a lid on
the bucket and let it sit for a month. The mosquitoes hatch and die in that
time.
Good growing,
Philip
