What causes streaking

Though not harmful or dangerous, black streaking on your roof may be a type of blue-green algae. This type of algae can break down the integrity of your shingle and lessen the lifespan of your roof. Oklahoma is among some states categorized as severe for homes to harbor algae growth, specifically because of the hot and humid climate in the summer months.
