Black Streaks Caused By Algae On Your Roof May Affect Your Home's Value
A quick look around your neighborhood may reveal roofs that look old and dirty. In reality, those roofs might not be old - or dirty. They may be covered with black streaks caused by algae - organisms that live on the roof's surface. The algae causes black streaks on the shingles, masking the roof's original color. A roof can make up to 50% of a home's exterior and is a key factor in its curb appeal. Black streaks on shingles can hurt the overall appearance of the house.
