Quick answer
Soft-wash roof cleaning in New Jersey typically costs $400–$800 for an average home, with most Ocean County roofs around $399–$650. The price depends on roof size, pitch, and how heavy the black algae streaking is. It's a fraction of the $8,000+ cost of replacing a roof aged prematurely by algae.
Those black streaks aren't dirt — they're algae eating your shingles. Cleaning is dramatically cheaper than replacing. Here's the real NJ pricing.
| Job | Typical price |
|---|---|
| Small / single-story roof | $399 – $499 |
| Average 2-story home | $499 – $700 |
| Large or steep / heavy moss | $700 – $1,000 |
