Hi everyone. New guy here. General question. I have plenty of roof but it is all asphalt shingle. Is it safe to harvest rainwater off an asphalt roof and use it for domestic water? We don't need to drink it but we do need to use it for everything else. Is it safe to use this water for plant irrigation? Any thoughts? Experiences with asphalt roofs?
Thanks for a great thread. Lots of good practical info here.
