Shingle roofs
Asphalt shingles are covered in granules that protect them from the sun. Pressure knocks those granules loose. Shingle roofs are cleaned with a soft wash solution and no pressure on the surface.
Tile roofs
Concrete and clay tile hold dirt and growth in their texture and channels. Tile is also soft washed. Walking on tile is limited because tiles can crack, so much of the work is done from ladders and the edges.
Metal roofs
Metal roofs get a film of dirt and growth too, especially on shaded sides. They're soft washed and rinsed so the finish isn't scratched.
Before the wash
- Move cars, grills, and patio furniture away from the drip line
- Close windows and turn off sprinklers
- Tell us about any known leaks or loose tiles
- Keep pets inside during the job
After the wash
Most streaks disappear the same day. Thicker growth like lichen may take a few rains to fully fall away. The gutters get rinsed as part of the job.
