What Causes Black Streaks on Your Roof?
The black streaks you see running down roofs all over Lake Mary, Heathrow, and Sanford are caused by a type of algae called Gloeocapsa magma. This algae is airborne — it spreads from roof to roof through wind and rain.
Florida's combination of heat, humidity, and frequent rain makes it the perfect environment for this algae to thrive. Once it takes hold, it grows quickly, creating those ugly dark streaks and patches that make your roof look old and neglected.
But it's not just cosmetic. This algae actually feeds on the limestone in your roofing materials, breaking them down over time. Left untreated, it can shorten your roof's lifespan by years.
