I had a new asphalt roof installed a few years ago and after a while dark stains started appearing on the fascia boards and siding. They are very difficult to remove. Somewhere I found an explanation for this but can't seem to find it now. It had something to do with how the job was done or how the shingles were stored before the roofing was installed. Can anyone help?
