Why Soft Wash

Pressure Washing Damages Roofs. Soft Washing Doesn't.

High-pressure washing strips protective granules, cracks shingles, and voids warranties. Soft washing achieves a deeper clean with zero damage.

❌ Pressure Washing

  • Strips granules from asphalt shingles
  • Can crack or dislodge tiles and cedar
  • Forces water under shingles → leaks
  • Voids most roofing warranties
  • Kills moss only on the surface — roots remain
  • Moss returns within 6–12 months

✅ Soft Wash (Our Method)

  • Low pressure — zero granule loss
  • Safe for all roof materials
  • Biodegradable cleaning solution
  • Kills moss, algae & lichen at the root
  • Results last 2–4× longer
  • Maintains manufacturer warranty
Our Process

How Our Soft Wash Cleaning Works

1

Inspect & Prepare

We assess your roof type and moss coverage, then protect your landscaping and windows before applying any solution.

2

Apply Bio-Wash Solution

We apply our EPA-approved, biodegradable cleaning solution at low pressure. It penetrates moss and algae, breaking down their cell structure.

3

Dwell & Kill

The solution dwells on the surface and kills organic growth from the inside out — reaching roots that manual brushing can't touch.

4

Rinse & Clear

Gentle low-pressure rinsing removes dead moss and debris. We clean up your gutters and surrounding areas before we leave.

What Our Customers Say

FAQ

Common Questions

Yes. We use biodegradable, EPA-registered solutions. We pre-wet and rinse surrounding plants before and after application as a standard precaution. Once dry (typically 1–2 hours), the treated area is completely safe for pets and people.
Soft washing typically keeps roofs clean for 2–3 years in Alaska's climate. Combined with our zinc prevention treatment, you can expect 4–5 years of protection. We recommend an annual inspection to assess regrowth.
We flush gutters and downspouts as part of every roof cleaning to clear dislodged moss and debris. Full gutter cleaning (leaf and debris removal) is available as an add-on service.
Spring and summer are ideal — warmer temperatures help the biocide solution work faster, and you'll head into winter with a clean, protected roof. That said, we service roofs year-round when conditions allow.
