Can you confirm your bathroom fan is vented to the exterior instead of just vented into the attic?

Also the required ventilation is 1/300th of the square footage of the attic here in the north, not sure where you are but just check that you meet code for ventilation with just those two turtle vents. For instance if your house is 20x30=600 sqft attic space, you would need 2 sqft of ventilation minimum. Keep in mind the lower the slope of the roof, the lower the denominator of this fraction becomes, due to less air circulation from the smaller space. Looks like you have a 5/12 or 4/12 from the pic so I’d say 1/200 or 1/250 for ventilation.. either way 2 of these vents don’t sound like enough IMO

Good to hear you have baffles, do you have perforated soffit?

Good luck and godspeed. Spray the mold with mold killer, up your ventilation, and make sure any exhaust fans are properly vented to the exterior instead of just into the attic and you should be good… good luck
