If you have ceiling water damage from the point below the attic or the roof itself, you are most likely facing damage to the roof. Roof damage arises from downed tree limbs and debris, bad weather, nesting animals, or faulty gutters.
Ceiling water stains near a fireplace could indicate faulty chimney flashing. This can result in damage to your roof, ceilings, or attic. Flashing strips should fit tightly around your chimney and should be checked every six months.
