Ellenwood, GA & Metro Atlanta
Professional Roof Cleaning Services in Ellenwood, GA
We use low-pressure soft washing — the only method recommended by roofing manufacturers — to safely remove black streaks, algae, moss, and lichen from your roof without causing damage.
Soft Wash Roof Cleaning vs. Pressure Washing
Not all roof cleaning is the same. Understanding the difference protects your biggest investment.
Soft Wash Roof Cleaning
Low-pressure application (under 500 PSI) combined with biodegradable cleaning solutions that kill algae, moss, and mold at the root. This is the method endorsed by the ARMA (Asphalt Roofing Manufacturers Association) and most shingle warranties.
Why it's right for roofs:
- Removes black streaks (Gloeocapsa magma algae) at the root
- Kills moss and lichen without high-pressure damage
- Safe for asphalt shingles — no granule loss
- Results last longer than pressure washing alone
- Protects roof warranty by following manufacturer guidelines
Pressure Washing a Roof
High-pressure water (1,500–3,000 PSI) blasts surface stains away but causes serious physical damage to asphalt shingles in the process. Most roofing manufacturers explicitly state that pressure washing voids shingle warranties.
Risks to your roof:
- Strips protective granules from asphalt shingles
- Forces water under flashing and into the attic
- Voids most shingle manufacturer warranties
- Breaks down adhesive strips that seal shingles
- Can loosen ridge caps and seams
At Pressure Washing Xperts we only use soft washing on roofs — never high-pressure. Learn more about soft washing vs. pressure washing →
