This is one of the larger cedar shake roofs we’ve cleaned in The Quarry. Multiple wings, dormers, skylights, a glass conservatory, and a stone entry portico — all covered in cedar shakes that had gone nearly black. Years of moss and algae had taken over, especially along the gutter lines where moisture gets trapped. The Quarry’s dense tree canopy and river humidity make this kind of buildup inevitable if the roof isn’t maintained. We treated the entire roof with our treatment process, and the difference was visible within minutes. The shakes went from charcoal-black back to their natural golden-tan — and we caught it on video so you can see it happen.
How Bad It Was
This roof hadn’t been cleaned in years. The shakes were almost uniformly dark charcoal-black, with heavy green moss along the lower courses underneath the tree canopy. This is what The Quarry’s microclimate does to cedar shake when it goes untreated.
The Whole Roof — Nearly Black
Every section of this roof is the same dark charcoal-black. Multiple wings, complex geometry, skylights — all of it covered in years of algae and organic growth. The Forza van is already in the driveway.
Up Close: Green Moss at the Gutter Line
This is what the homeowner could see from the ground — heavy green moss along the lower courses, gray-brown weathered shakes, and organic growth that had been building for years. This kind of moisture retention is what shortens the life of cedar shake if it goes untreated.
Moss and Algae Buildup
Watch the Treatment Work
While Korey worked from a ladder with professional standoffs, we recorded the treatment in progress. The treated sections turn golden-tan almost immediately — and the untreated sections stay dark charcoal. You can see the exact line where the treatment has been applied.
Treatment in Progress
Korey is on the ladder applying treatment section by section. Watch the left side of the roof — it’s already golden-tan where the solution has been applied. The right side is still the same charcoal-black it was before. That contrast is the treatment working in real-time.
Half Treated, Half Untreated — Same Roof
Why This Matters
Most roof cleaning companies show you a before photo and an after photo taken weeks apart. Here, you can see the transformation happening on the same roof, at the same time. Treated sections are golden-tan. Untreated sections are still dark charcoal. There’s no question about whether it’s the same property or the same roof — the proof is in the contrast.
Why Quarry Roofs Get This Bad
The Quarry on the Scioto sits in a natural limestone quarry basin along the Scioto River. The combination of river humidity, quarry-wall wind patterns, and dense mature tree canopy creates a microclimate that accelerates organic growth on cedar shake roofs. Homes on Quarry Ln sit at the heart of this environment — surrounded by hardwoods on all sides with limited direct sunlight reaching the roof surface. Without regular treatment, the shakes darken from golden-tan to gray to charcoal to near-black within a few years. Read more about The Quarry →
