This is a cedar shake roof cleaning job from a wooded estate home in The Sanctuary, Columbus, Ohio. This is one of the largest and most complex roofs we've treated in The Sanctuary — a massive cedar shake surface with multiple hips, valleys, skylights, a brick chimney, and a stone patio tucked beneath a dense hardwood canopy. Years of shade and moisture had turned the shakes dark gray-black with green-black algae staining concentrated on the rear slopes. After treatment, the entire roof returned to a warm golden-tan. The neighbor's untreated dark roof next door provides a striking contrast in the after photos. GPS verified in The Sanctuary, Columbus, Ohio. Learn more about our Sanctuary services →
The Sanctuary's Largest Cedar Shake Roofs
The Sanctuary contains some of the largest cedar shake roofs in Central Ohio. These estate-sized homes often exceed 5,000 square feet of roof surface, with complex geometries that include multiple skylights, dormers, and chimney penetrations. Each of these features creates a potential moisture trap where organic growth can take hold. Combined with the community's dense hardwood canopy and ravine humidity, these roofs require professional maintenance on a regular cycle to prevent permanent damage to the wood grain.

The Transformation
The Sanctuary — Full Overhead (Before vs. After)
Cedar Shake
Same drone position, same home, completely different roof. This is the showcase photo — a perfect angle-matched before and after from directly above. In the before, the massive cedar shake surface is a dark gray-black with the skylights barely visible through the weathering. The curved driveway, brick-bordered walkway, and stone patio with covered furniture are all visible. After treatment, the shakes have returned to a warm golden-tan across the entire surface. The rear sections under the densest canopy still show slightly darker tones — that's the natural variation of cedar aging under different light conditions, not residual growth.
The Sanctuary — Rear Skylights & Neighbor Contrast (Before vs. After)
Cedar Shake
The before shot zooms in on the rear section where the damage was worst — you can see the skylights surrounded by dark gray-green shakes, the brick chimney, and the stone patio below with covered outdoor furniture. The after shot pulls back to reveal the full transformation, and here's the kicker: look to the right. The neighbor's untreated cedar shake roof is still dark gray-black — the exact same color this roof was before treatment. That side-by-side contrast tells the whole story without a single word.
Spot the Difference: Treated vs. Untreated
In the second slider's after photo, the neighbor's untreated cedar shake roof is clearly visible on the right side of the frame. The dark gray-black surface is the exact same condition this roof was in before treatment. This kind of side-by-side comparison is only possible in communities like The Sanctuary where every home carries the same roofing material — and it makes the transformation impossible to miss.
The Sanctuary — Side View & Full Roof (Before vs. After)
Cedar Shake
This pairing shows the two-tone problem that plagues Sanctuary roofs. In the before shot, you can clearly see the contrast between the lighter gray front-facing slopes (which get some sun) and the dark green-black rear slopes (which sit under constant canopy shade). The skylight is barely visible through the algae staining. After treatment, the full overhead view shows a uniform golden-tan across every slope. The American flag at the curb and the early autumn colors in the trees frame a home that looks completely renewed.
The Problem: Complex Geometry Traps Moisture
This close-up of the rear roof section reveals the challenge. The complex geometry — multiple hips meeting at different angles, a skylight, and vent pipes — creates pockets where moisture pools and organic debris collects. Pine trees pressing in from above drop needles directly onto the surface. Every one of these features is a moisture trap, and together they've turned the shakes to a very dark gray-black that's far beyond normal weathering. This is active biological growth that will eventually compromise the wood if left untreated. Our treatment process kills the growth at the root and lets the cedar breathe again.
The Final Result
The Sanctuary — front elevation after treatment. This is the view from the street — the one that matters most to homeowners. The cedar shakes glow a warm golden-silver in the sunlight, the cream siding looks fresh against the natural wood, and the mature Japanese maple and brick-bordered walkway complete the picture of a Sanctuary estate that looks exactly the way it was designed to look. This is what professional cedar shake maintenance delivers — not just a clean roof, but a home that commands the curb appeal its neighborhood deserves.
