Moss & Algae Removal in Barstow, California
The desert is dry, but the shaded north slopes and the rare damp spells can grow the moss and the algae. The dark streaks on the shingles are the algae taking hold. Moss and algae removal in Barstow means the cleaning and the treatment that keep the roof clean.
Signs Your Barstow Roof Has Moss or Algae
- Dark green patches on the north slope — the shaded side grows the moss
- Black streaks running down the roof — the algae growing on the surface
- Lifted shingles near the tree line — the moss pushed up under the edge
- A gritty, dirty surface — the sand and the growth combined
- Stains in the valleys — the debris and the moisture collected
Why Moss Grows in the Desert
The shade is the main reason. The north slopes get the least sun, and the rare rain leaves them damp the longest. The moisture feeds the moss and the algae, and the growth takes hold.
The wind-blown sand adds to the problem. The sand settles on the surface and holds the moisture, giving the growth a base. The shaded spots grow the fastest.
How We Remove Moss and Algae in Barstow
- Inspect the roof — find the growth and the shaded areas
- Apply the treatment — the soft-wash solution that kills the growth
- Rinse the surface — the low-pressure rinse, no damage
- Treat the north slope — the shaded areas get the extra treatment
- Apply the preventive — the treatment slows the regrowth
