The "before" photos we took of homes show the following destructive symptoms:

 

• Black Streaks -  An airborne virus caused by humidity, moisture and shade. The virus feeds on crushed limestone from your shingles.

 

• Lichen - A combination of algae and fungus that has a light, mint green color. Lichen is about the size of a silver dollar and will eventually eat away at shingles.

 

• Moss - Dark green in color, very thick and retains water. Moss also grips into the surface of the shingle.

 

In the "after" photos, you'll notice that our roof washing process got rid of the problems.
