Living in a humid area of the country, you’ve probably have seen dark streaks on asphalt shingle roofs. Though often attributed to an accumulation of dirt, defective shingles, mold, or mildew; the most common culprit is actually a blue-green algae known as Gloeocapsa Magma that is spread by airborne spores. We utilize our soft wash system with zero pressure to kill the algae at its roots.
