Staining from siding caused by asphalt shingles

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?

Hello Sam I am....nice name...you can tell I have children

Usually all that staining is mold.

Species...foundeverywhereyoulookhardtoremovus..

Usually just cleaned up with some TSP cleaner(ask your hardware folks)or some bleach and water mix. And....lots of that ol' standby...elbow grease...so roll up those sleeves and get a scrubbin broom.

Basically it will show up on the shingles as run marks down the roof...then down the gutters and fascias.

Nothing to worry about.
Turn on the radio and have at it.
