Were there a roof leak you would see the spots usually resembling toast, in color.Is chipping off the cracking spots and repairing a realistic option? Can I assume there will not be further damage to the areas we do not fix?
The ceiling and the painted surface are an effective barrier to moisture transition to a ventilated and insulated attic, so the attic insulation will have no effect.Could the attic insultation be not allowing for full ventilation? I was reading that often it is too far in certain areas.
The fan in the bathroom is the first thing you want to look at with a problem in the bathroom.I understand. It may just move slowly we could afford to hire but we just dropped several thousand on the other issue so I would prefer to avoid that.
