Why Lowcountry Roofs Get Dirty Faster

Those black streaks aren't dirt — they're Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. The Coastal Empire and Lowcountry's warm, humid climate is ideal for it. Left untreated, it traps moisture against your shingles, accelerates granule loss, and shortens your roof's lifespan by years.

High-pressure washing is the wrong fix. It strips granules, voids manufacturer warranties (GAF, CertainTeed, Owens Corning), and can crack tiles. Soft washing is the only method these manufacturers recommend. We apply a low-pressure cleaning solution that kills the bacteria at the root — the streaks are gone and they stay gone for 2–4 years.

Low-pressure application from the ground or roof edge. No walking on your shingles, no high-pressure nozzles.

Roof Cleaning FAQ

What causes the black streaks on my roof?
Black streaks are caused by Gloeocapsa magma, a type of cyanobacteria (blue-green algae) that feeds on the limestone filler in asphalt shingles. It thrives in the warm, humid climate of the Coastal Empire and Lowcountry. It's not just cosmetic — it damages shingles over time by retaining moisture and accelerating granule loss.
How much does roof cleaning cost in Savannah?
Roof cleaning in the Savannah and Lowcountry area typically costs $300–$800 depending on roof size, pitch, stories, and condition. A standard 1,500–2,000 sq ft roof on a single-story home usually runs $350–$500. We provide exact pricing in your free estimate.
Will pressure washing damage my roof shingles?
Yes — that's why we never pressure wash roofs. High pressure strips granules from shingles, voids manufacturer warranties, and can crack tiles. We use a soft wash method: low-pressure application of a cleaning solution that kills algae and bacteria without any surface damage. This is the method recommended by shingle manufacturers like GAF and CertainTeed.
How long does a roof cleaning last?
A properly soft-washed roof stays clean for 2–4 years in the Savannah and Lowcountry area. Roofs with heavy tree cover or north-facing slopes may see regrowth sooner. Some homeowners add a preventive treatment annually to extend the clean.
Can roof cleaning extend the life of my roof?
Yes. Algae and moss trap moisture against shingles, accelerating deterioration. Regular soft wash cleaning removes these organisms and can add years to your roof's lifespan. It's significantly cheaper than early roof replacement — a $400 cleaning vs. a $15,000+ re-roof.
