Those are rust stains on the slate, and while they are not hurting anything, don't expect them to fade either. Painting the roof will help to stop the rusting and may further the life of the flat seamed roof. Soffit vents won't hurt anything and they will make the attic cooler in the summer, especially if you leave the window of the dormer open to let the heat out. I am sure there is no insulation in anything so the house is probably drafty and it is by definition "venting itself" 134 year old slate roof. not too bad!

Just bought house with slate roof built in 1874. The eaves and gutters are destroyed. The attic is unfinished and I have no plans to ever finish it. I seem to remember reading somewhere on here that although slate is water-tight, it is not air-tight, and doesn't require the same ventilation as other roofs do. Does this mean I do not need ventilated soffits?
Also, regarding these stains, will painting the steel stop the staining and will the stains fade? Thanks for providing such great information.
