Wood Shake Roof Washing
Safe Soft Washing for Cedar & Wood Shake Roofs in Pittsburgh & Surrounding Areas
Wood shake roofs offer natural beauty and character that few other roofing materials can match. However, wood roofing requires specialized care to prevent decay, moss growth, and premature deterioration.
If your cedar shake or wood shingle roof is darkened, streaked, or covered in moss, professional soft washing is the safest and most effective solution.
At So Clean Solutions, we provide expert wood shake roof washing using a low-pressure cleaning system designed to remove organic growth while preserving the integrity of the wood.
Why Wood Shake Roofs Require Specialized Cleaning
Wood is a natural, porous material. That means it absorbs moisture — and when moss, algae, or lichen grow on the surface, they trap even more moisture against the wood.
Improper cleaning methods, especially high-pressure washing, can:
- Split or shred wood fibers
- Accelerate deterioration
- Force water deep into the shakes
- Remove protective surface layers
- Reduce roof lifespan
That’s why we use a carefully controlled soft washing process specifically designed for wood roofing systems.
Common Problems We Treat on Wood Shake Roofs
In Pittsburgh’s humid climate, wood roofs are particularly vulnerable to organic growth.
We safely remove:
- Moss buildup between shakes
- Algae staining and dark streaks
- Lichen growth attached to wood fibers
- Mold and mildew
- Organic debris accumulation
If left untreated, these contaminants can lead to rot, warping, and costly repairs.


Our Wood Shake Roof Soft Washing Process
Each wood roof cleaning begins with a detailed inspection to evaluate shake condition and identify any areas of concern.
Step 1: Roof Assessment
We examine the shakes, flashing, and overall roof condition.
Step 2: Landscape & Surface Protection
Plants and surrounding surfaces are pre-soaked and protected.
Step 3: Soft Wash Application
We apply a professional cleaning solution that eliminates moss, algae, and lichen at the root.
Step 4: Gentle Rinse (When Required)
If rinsing is necessary, we use carefully controlled low pressure to avoid damaging wood fibers.
Our process removes harmful growth while helping preserve the natural structure of your wood shakes.

How Often Should a Wood Shake Roof Be Cleaned?
Wood shake roofs typically require cleaning every 2–3 years, depending on:
- Tree coverage and shade
- Moisture exposure
- Roof pitch and drainage
- Visible moss or algae growth
If you see moss forming between shakes, it’s important to address it quickly before root systems penetrate deeper into the wood.
