Black Stains on Your Miami Roof Here Is What They Are and How to Remove Them
Black stains on roofs in Miami are commonly caused by algae known as Gloeocapsa magma. This algae thrives in warm, humid environments and feeds on the limestone filler in asphalt shingles, creating dark streaks across the roof. Although the stains start as a cosmetic issue, they can trap moisture and gradually weaken roofing materials. Professional soft-wash roof cleaning is the safest way to remove the stains and restore your roof’s appearance while preventing further algae growth.
