This is a slate roof cleaning project from a large estate home in New Albany, Ohio. This property features a complex slate roof with multiple dormers, copper-capped cupolas, and an attached glass conservatory. Years of weathering had left the slate darkened with algae and biological staining. After Forza's professional treatment, the natural slate color was restored — without a single tile disturbed. All work was assessed and verified by drone. Learn more about our New Albany services →
Slate Roofs in New Albany
New Albany is home to some of Central Ohio's finest estate properties, many featuring natural slate roofs that can last 100+ years when properly maintained. The area's mature hardwood canopy and humid summers create ideal conditions for algae, moss, and lichen growth on slate surfaces. Because slate is fragile and irreplaceable, it demands a no-walk, no-pressure approach — exactly what Forza specializes in. Our drone assessment identifies every problem area before we begin, and our treatment process cleans the slate without any foot traffic on the roof surface. Read more about New Albany roof cleaning →

After Forza's treatment, the natural gray-blue slate color is restored. The copper-capped dormers, attached conservatory, and manicured brick patio are all visible in both shots — confirming identical vantage points. No pressure washing was used. No foot traffic on the slate.
