What is on your roof is not dirt! The blackness is actually mildew that lands as a spore, germinates and then grows using the surface as a nutrient base. Mildew will always appear initially on the N side of your house and roof. This is because moisture stays there longer and mildew requirements three things to grow: moisture, heat and several sort of nutrient.
