Moss & Algae Removal in Palm Desert, California

The Palm Desert winters bring the rain, and the shaded spots on the roofs grow the moss and the algae. The growth holds the moisture against the shingles and ages the roof faster. Moss & algae removal in Palm Desert protects the shingles from the moisture the growth traps.

Signs Your Palm Desert 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 Palm Desert Roofs Get Moss and Algae

The desert winters bring the rain, and the shaded slopes stay damp after the storms. The shade from the trees and the buildings keeps the moisture on the roof, and the moisture feeds the moss and the algae.

The algae eats the limestone filler in the shingles, and the moss holds the water against the surface. Both age the roof faster than the sun alone.

How We Remove Moss and Algae in Palm Desert

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 Palm Desert

• 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

Expert tip: in Palm Desert, the moss concentrates on the shaded slopes that get the least sun. The shaded spots stay damp after the winter rain, and the moss takes hold.
