Spartanburg roofs in Converse Heights, Hampton Heights, Duncan Park–Forest Hills, and Fernwood sit under mature trees, and the black streaks on those slopes are usually Gloeocapsa magma rather than soot. Spartanburg County's humid summers keep north-facing shingles damp. Loblolly pine pollen from late March through April lands on the same slopes and gives the algae more to work with once the weather warms. A streaked roof over an older two-story is a common spring call in these blocks.
Pressure washing is the wrong fix. ARMA tells owners not to use a pressure washer on asphalt shingles. GAF warns that power washing can knock granules off and shorten the roof. The job is a soft wash: cleaning solution at low pressure, dwell time, then a gentle rinse. Ask how plantings along Hampton Heights foundations get pre-wet and rinsed, because the mix can burn leaves.

That is a national cost-guide range; local quotes vary with pitch and height. Pros who list Spartanburg rank with up to three Top Spots, then Featured profiles, then the rest.
