Leaky metal roof...only a couple years old.
We moved into our hourse a little over a year ago. A month ago my wife was pulling something out of a closet in our spare room. She noticed it was had black mold on it. Looking up the wall we noticed a small trickle of water coming from the crown molding. It was raining at the time. Pulling the ceiling tiles down, we discover soggy insulation and a metal roof with no decking. We notice the trickle originates from behind one of the trusses. This happens whenever it rains. I don't know if its related but we also had a small leak develop in our kitchen for one night. We haven't noticed it since that initial time though.
What exactly could be causing this and what would I need to do to fix it. Money is tight at the moment so if there is something I could do myself I would prefer that. If not though I would understand though. Thanks
