MAKE YOUR ROOF LOOK NEW!
.
The main bacteria causing these “black-streaks” on roofs is called Gloeocapsa Magma, this bacteria as well as other bacteria, algae, molds, fungus and lichen are one of the main causes of roofing material breakdown and decomposition. The lichen has a filament root system that will grow down into an asphalt shingle to feed and ultimately pull the aggregate granule layer off exposing the asphalt layer therefore starting a rapid deterioration.
