Roof Cleaning in Eureka, California

The fog keeps the shaded slopes damp, and the damp feeds the moss and the algae. The growth traps the moisture and hides the real condition of the roof. Roof cleaning in Eureka means clearing the surface so the shingles can shed water.

Signs Your Eureka Roof Needs Cleaning

• Green or dark patches on the north slope — the moss in the shade
• Moss in the valleys and the joints — the damp spots hold the growth
• Black streaks running down the shingles — the algae feeding on the granules
• Leaves and debris in the corners — the redwood canopy drops the needles
• Stained or discolored shingles — the surface has lost its clean look

Why Eureka Roofs Need Cleaning

The fog is the main reason. The coastal fog keeps the north-facing slopes damp for much of the year, and the moisture feeds the moss and the algae. The shaded slopes stay green while the sunny slopes stay clean.

The redwood canopy adds the debris. The tall trees drop the needles and the twigs, and the debris traps the moisture against the shingles.
