Moss & Algae Removal in Redondo Beach, California

The coastal fog and the damp air make Redondo Beach a perfect home for moss and algae. The shaded slopes stay moist for days after the rain, and the growth feeds on the moisture. Moss and algae removal in Redondo Beach protects the shingles from the damage the growth causes.

Signs Your Redondo Beach Roof Has Moss or Algae

• Green or black patches on the shaded slopes — the moss is taking hold
• Black streaks running down the roof — the algae is feeding on the shingles
• Moss growing in the valleys and around the flashings — the growth is in the vulnerable spots
• Lifted or curled shingle edges — the moss pushed under the edges
• The roof stays damp after the rain — the growth is holding the moisture

Why Redondo Beach Roofs Get Moss and Algae

The coastal fog is the main cause. The damp air keeps the roofs moist, and the shaded slopes where the sun does not reach grow the moss and the algae.

The algae eats the limestone filler in the shingles, and the moss holds the water against the surface. The moss is the bigger problem. It lifts the shingle edges and ages the roof faster.

How We Remove Moss and Algae in Redondo Beach

1. Inspect the roof — locate the growth and check the shingle condition
2. Treat the growth — apply a moss and algae treatment to the affected slopes
3. Soft wash the roof — a low-pressure rinse that removes the growth
4. Hand remove the heavy spots — scrape the moss from the valleys and the flashings
5. Protect the roof — apply a treatment that slows the regrowth

Preventing Moss and Algae in Redondo Beach

• Trim the tree branches over the roof — the shade feeds the growth
• Clean the roof every two to three years — the growth is easier to prevent than to remove
• Add zinc strips at the ridge — the zinc washes down and slows the algae
• Keep the valleys clear of debris — the trapped leaves hold the moisture

Moss tip: in Redondo Beach, the fog-fed slopes grow the moss and the algae year-round. The shaded slopes are the ones we treat every year.
