I was looking in my attic today for the first time; it's been on my list to check up there to make sure nothing looks off (i.e. no water damage, the roof isn't falling apart, etc).
Normally I'd just assume this is dust settling in the attic which I never go up in, but after Googling a bit it apparently could be mold. I'd like to get a second opinion to determine if it's mold growing in the pink insulation or if it's just dust settling on top.
If the images I've posted do not provide the proper insight please feel free to comment to let me know and I can provide more specific pictures.
