Hello folks I'm new here. I am trying to see if this is mold growing in my attic. Its only on a few rafters. Cleans off easy and not spore like. and only on one side of my attic. I do not have outside soffits but I do have a ridge vent and gable vents. Both of which are clear and clean. I have no blackish type mold groth in the attic just this oin and in between maybe 8 rafters
