Soft Washing for Tile Roofs is one of the jobs we do most often in Missouri. Typical jobs cost $300-$800, and you approve the price before we begin. On tile roofs, the method we use is soft wash.
Method and pressure
Cleaning solution: A soft wash solution; moss and lichen may need a second application.
What to know about cleaning tile roofs
Clay and concrete tile roofs grow algae, moss and lichen, especially in shade. Tiles are brittle when walked on, so roof access is planned carefully and the roof is cleaned mostly with solution.
Avoid: High pressure, which erodes the surface of concrete tile, and stepping on the middle of tiles.
How often: Every 3-5 years.
Signs you need soft washing for tile roofs
- Green, black or gray film on siding, especially on the north side
- Black streaks running down the roof
- Moss or lichen on shingles or tile
- A musty smell around shaded walls
- Pressure washing would damage the surface
Where the grime comes from
- Algae, mold and mildew that grow in shade and humidity
- Roof algae that feeds on the limestone filler in shingles
- Pollen and dust that give growth something to hold on to
- Sprinklers and gutters that keep walls damp
Safe steps for homeowners
- Trim back branches and shrubs that touch the house so walls can dry

- Spot-clean small areas with a soft brush and mild detergent
- Aim sprinklers away from the house

Every 3-5 years. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
