Customer has streaks on his roof in some places. These are not the typical dark streaks but are lighter than the shingles. And tend to run horizontal instead of vertical.
Second problem is before gutters were installed his air conditionning unit dripped unto the roof leaving a "gray" spot. I assume the spot is from minerals in the water, but what removes them from the shingle without damage? Any help is appreciated. Will try to post pics.
