This is a cedar shake roof cleaning job from a tree-canopy home in The Sanctuary, Columbus, Ohio . This beautiful home sits beneath a dense hardwood canopy that had turned the rear roof slopes bright green with algae and moss while the front-facing slopes had weathered to a flat gray. The contrast between the shaded rear and the exposed front told the whole story — tree canopy creates the perfect environment for organic growth on cedar shakes. After treatment, every slope returned to a uniform golden-tan, and the Forza van parked across the street tells you who did the work.

Why Tree Canopy Destroys Cedar Shakes
In The Sanctuary, nearly every home sits beneath a dense hardwood and pine canopy. It's a beautiful, serene setting to live. The combination of constant shade, trapped moisture, and falling organic debris creates a microclimate on the roof surface where algae, moss, and lichen thrive. Rear-facing slopes that receive the least sunlight always show the worst growth — exactly what we see in this home's before photos. Our treatment process kills organic growth at the root without damaging the wood grain. Read more about The Sanctuary →
The Transformation
The Sanctuary — Full Overhead (Before vs. After)
Cedar Shake
The full overhead view tells the story. This large cedar shake home sits beneath a dense hardwood canopy, and the rear slopes had turned bright green with algae while the front slopes were flat gray. After our treatment, every surface has returned to a uniform golden-tan. Look across the street in the after shot — the Forza van is parked right there. The covered porch with boxwood hedges, the patio with outdoor furniture, and the manicured landscaping with a red Japanese maple all frame a roof that looks like new from the air.
The Sanctuary — Rear Slopes & Tree Canopy (Before vs. After)
Cedar Shake
This pairing highlights the worst of the damage. The before shot zooms in on the rear roof slopes where the tree canopy presses closest — you can see heavy green algae and moss staining across the entire surface, with the vent pipe and dormer surrounded by growth. The after shot pulls back to show the full home surrounded by its dense tree canopy, with every shake now restored to golden-tan. The brick chimney, curved front walkway, and lush landscaping complete the picture of a Sanctuary home that looks the way it should.
The Problem: Green Algae Thriving Under Tree Canopy
This close-up of the rear roof slopes shows exactly what happens when cedar shakes sit beneath a dense tree canopy year-round. The green algae has colonized the entire surface, turning the shakes from their natural golden color to a sickly green-gray. You can see how the growth is heaviest where the canopy is densest — the trees are literally dripping moisture and organic debris onto the roof surface. This is the most common condition we see in The Sanctuary, and it's exactly what our treatment process is designed to treat.
The Final Result
The Sanctuary — full home view after treatment. The cedar shakes have been restored to a warm golden-tan across every slope. The white siding pops against the natural wood, the brick chimney stands clean, and the dense tree canopy that caused the problem now frames a home that looks like it belongs in this woodland setting. Behind the home, a wooden fence borders the ravine — the same environment that makes The Sanctuary beautiful is the same one that makes professional cedar shake maintenance essential.
