Re: Black marks on ceiling
If it was on the north side I would think you are correct that it was moisture from an ice dam. If I see what I think it mold, I just write that it looks like mold or fungus is present, etc.
Re: Black marks on ceiling
The whole house has these marks, house faces west but most of marks are on west and east sides of house some on the north and south.

Re: Black marks on ceiling
I was thinking along the same line as Bruce-- 'ghosting'. There is the other question of mold in the attic. You have to be careful with calling the wood members as 'mold' as alot of times this will not be mold on framing members.

Re: Black marks on ceiling
I am not sure what you are refering to as "ghosting". Please expand on this.

Hello Brian,
Instead of beating around what this issue is, I'll provide you with a document that you can keep and reference for the future as back-up.
From the BuildingScience.com website, here is a document that will help clarify any questions that you may have regarding "ghosting"
Good reading... but you have to read it all-- that's the deal ;)
