Tile Roof Washing
Safe Soft Washing for Clay & Concrete Tile Roofs in Pittsburgh & Surrounding Areas
Tile roofs are known for their durability, longevity, and distinctive appearance. Whether you have clay tile, concrete tile, or Spanish-style barrel tile, proper maintenance is essential to protect your investment.
If your tile roof is covered in black streaks, moss, algae, or mildew, professional soft washing is the safest and most effective cleaning method.
At So Clean Solutions, we specialize in low-pressure tile roof washing that removes organic growth without cracking, shifting, or damaging your roofing materials.
Why Tile Roofs Require Professional Soft Washing
Tile roofing systems are strong — but they are not designed for high-pressure cleaning. Pressure washing can:
- Crack clay or concrete tiles
- Break tile corners and edges
- Dislodge tiles from their fasteners
- Strip protective coatings
- Force water beneath the underlayment
Our soft washing process eliminates stains and biological growth at the root without the risks associated with pressure washing.
Types of Tile Roofs We Clean
We provide expert cleaning for:
- Clay tile roofs
- Concrete tile roofs
- Spanish / barrel tile roofs
- S-tile roofing systems
- Flat interlocking tile roofs
Each roof type requires careful handling and proper chemical balance to ensure safe, long-lasting results.
Common Tile Roof Issues We Treat
Western Pennsylvania’s moisture, tree coverage, and seasonal changes create ideal conditions for roof staining and biological growth.
We safely remove:
- Black streaks caused by algae
- Moss growth between tiles
- Lichen attached to tile surfaces
- Mold and mildew buildup
- Rust stains around fasteners
- Organic debris accumulation
These contaminants trap moisture and can shorten the life of your roof if left untreated.


Our Tile Roof Soft Washing Process
Every project begins with a careful inspection to ensure your tile system is structurally sound before cleaning.
Step 1: Roof & Property Assessment
We inspect tile condition, flashing, ridge caps, and surrounding landscaping.
Step 2: Landscape & Surface Protection
We thoroughly pre-soak and protect plants, siding, and hardscapes.
Step 3: Soft Wash Application
We apply a professional-grade cleaning solution that kills algae, moss, and lichen at the root.
Step 4: Controlled Rinse (If Needed)
Low-pressure rinsing ensures proper results without damaging tiles.
Unlike surface-level pressure washing, our method continues working after application to provide longer-lasting cleanliness.

Routine maintenance is far more affordable than repairing or replacing damaged tile sections.
How Often Should a Tile Roof Be Cleaned?
Most tile roofs should be professionally soft washed every 3–5 years, depending on:
- Tree shade and debris exposure
- Roof pitch and drainage
- Local humidity levels
- Visible algae or moss growth
If you see black streaks or green patches forming, it’s time for an evaluation.
