I've run into that also from time to time. There are a lot of different reasons for color variations or "shading" on some asphalt shingle roofs. Got any pics of what you're talking about?

Usually, if they are the stains I have experienced, one or two good hard rain falls and they come off.

What Doug said....

if those are stains on paint, sometimes the GM can actually eat into the pigment and leave discoloration streaks.

Sorry I don't. I actually had a customer tell me that she heard that cetain manufacturers shingles were suseptible to staining (which looks like GM).

That's must have been a relief to you. I have not been that fortunate.

Pictures would help us trouble shoot the issue.

Take a look at the attached document it may provide some clarity. I did not take notice to what part of the country you are in so I cant promise this is cause.

Pictures are worth a 1000 words

Thanks Matt. I saved it. Maybe I will give a copy to my customers with an explanation in the future if I come across it again.

I'm in the Pittsburgh, PA area.

If I come across it next time I will. Usually when I come across something like that I figured why take a picture. Doesn't make it good for a before and after.

How old is the roof? Perhaps it is in part due to granular loss from previous "jack-legs" and/or age????

This happened on a few roofs and different ages of the roof.
