I had to deal with mold in the bathroom from a leaking roof in 2005, and I got my homeowners to pay for it, they covered mostly everything, and everything went. So now, the bath is mold free. My homeowners was great, they even sent out a sample of the mold to be tested and it was confirmed as the kind to cause pneumonia, which at the time, I was also, dealing with. So, it is really important you pull out all that insullation just in case, and if it is wet in your attic yet, you might need to rent a dehumidifier and an air-scrubber machine, and let them run until, it is dry. For me, it had taken a solid week to dry in the floor joists, in the walls, etc., but it was worth it. Also, I don't now if you mentioned this, or not, but do you have a bathroom fan venting into the attic? You might also, need to add some roof vents, if you haven't already.
