Roof mold

[botelj]

I looked in my attic and noticed my contractor did not exaust my bathroom fan at all he just exausted it into my attic. I repaired that but now notice black on the ceiling of my attic and it looks like mold. I tried to use bleach and water to repair it but this does not seem to work any one have a solution???

Not sure what you got, is the wood black or is black on the wood or in the wood, but if you used bleach and it didn't affect I am sure its not mold.
