Moss & Algae Removal in Seaside, California

The fog and the shaded slopes keep the Seaside roofs damp, and the moss grows on the north side. The moss lifts the shingles and the moisture gets in. Moss and algae removal in Seaside clears the growth and protects the roof.

Signs Your Seaside Roof Has Moss or Algae

• The green patches on the roof — the moss is growing on the shaded slopes
• The dark streaks on the roof — the algae is growing on the damp areas
• The lifted shingles — the moss is growing under the shingles and lifting them
• The debris on the roof — the leaves trap the moisture
• The damp smell in the attic — the moisture is trapped under the growth

Why Seaside Roofs Get Moss and Algae

The fog and the shade create the conditions. The fog keeps the roofs damp and the north-facing slopes stay shaded. The moss and the algae grow in the damp, shaded areas.

The moss is the bigger problem. The moss lifts the shingles and the water gets in. The algae is a cosmetic issue, but the moss is the structural damage.

Preventing Roof Problems in Seaside

• Trim the branches over the roof — the sun needs to reach the roof

• Check the north-facing slopes — the shaded slopes grow the moss first
• Clean the gutters — the debris traps the moisture and feeds the growth

Expert tip: in Seaside, the moss is the bigger problem than the algae. The moss lifts the shingles and the water gets in. The treatment kills the moss and the scraping removes it, but the tree trimming prevents the recurrence.
