Mauldin roofs in Butler Station, Holly Springs, and Brookside grow the same black streaks seen across Greenville County. The cause is usually Gloeocapsa magma on asphalt shingles, fed by humidity and by shade from backyard trees. Pine pollen from late March through April settles on the roof and in the gutter at the same time. When the gutter overflows, you get streaks on the fascia and red clay splashed on the siding below, which is a different job from the algae on the field of the roof.
Leave the pressure washer in the truck. ARMA recommends a gentle cleaning solution and no high pressure on shingles. GAF says power washing dislodges granules. A soft wash is the method: apply, dwell, rinse low. Mauldin is in Greenville County, so ask how wash water is kept out of storm drains on curbed streets.
Guides put typical roof cleaning at $450–$700 and soft washing near $0.30–$0.75 per square foot. That is a national cost-guide range; local quotes vary with how dark Holly Springs shade has made the north plane. Listings rank up to three Top Spots, then Featured, then the rest. The $40 deposit is credited to the job.
