Why are there dark patches and stains on my roof and what is causing them?

The main cause for black streaking and dark patches on roofs is Gloeocapse Magma. This algae can infest a roof and leads to the why the roof looks so dirty. Warm, humid environments are a perfect incubator for this particular strain of algae. South West Florida is one of those "perfect environments". The chlorophyll-containing algae makes the black streaks and stains standout by covering the roof shingles or concrete tiles.
