Sounds like some kind of a short induced by the presence of the water. or else something where the water is creating an open ciruit, although this ought to be less likely. I would check for places where either a) something is grounded - like the water, telephone, electrical system - and see if something else, even one of the others, comes close enough for water to cause a short; b) is the metal roof grounded ? Perhaps it needs to be; c) when you shut off all of your breakers, check where the power comes into the house to see if the noise is louder/stronger there - if so there may be a short on the incoming line. In short, any place where water might temporarily create a connection between two metal items which don't normally come in contact could be a cause.
