Service Description:
We use a low-pressure soft wash system with an eco-friendly solution designed specifically for roofs. This treatment safely kills remaining moss spores, lichen, algae, and other organic growth that brushing alone can’t remove, restoring your roof’s natural color and appearance while helping to extend the life of your shingles.
Why It's Important:
Brushing alone removes 90-95% of visible moss, but tiny moss spores can remain and regrow quickly, especially in Humboldt County’s damp, shaded climate. This treatment targets spores at the root, preventing regrowth and reducing long-term moisture damage. It also helps remove black algae streaks, lightens discoloration, and adds protection to your shingles, helping your roof last longer and maintain its curb appeal.
Recommended Cleaning Frequency:
Every 1-2 years, or as needed. Typically performed after a Roof Clean-Off / Moss Removal to ensure complete protection. Some homeowners use it as a preventative service between cleanings, while others choose it as a standalone treatment depending on roof condition and exposure.
