Moss & Algae Removal in Los Altos, California

The mature trees in Los Altos shade the roof, and the moss and the algae follow the shade. The green growth looks bad, and it holds moisture against the shingles. Moss & algae removal in Los Altos means the treatment that clears the growth and protects the roof.

Where Moss Grows in Los Altos

• The north-facing and the shaded slopes
• The areas under the tree canopy
• The flat sections where the water lingers
• The valleys and the low spots
• The roof sections that never dry out

Why Moss Damages the Roof

The moss holds the moisture against the shingle surface. The constant damp breaks down the asphalt and the granules, and the shingle ages fast. The moss roots also work into the shingle edges and lift them.
