Roof Cleaning & Moss Removal in Tacoma & Seattle - Soft Wash Experts

Gentle, manufacturer-approved soft washing that protects shingles, removes algae & moss, and extends the life of your roof. Backed by a 2-year moss-free warranty.

Why Tacoma Roofs Need Regular Cleaning

Moss, algae, lichen, and organic buildup trap moisture and accelerate shingle wear. Left untreated, this can lead to leaks, reduced roof lifespan, and costly repairs. Our soft wash method removes these growths at the root, safely and effectively.


We use manufacturer-friendly low pressure and biodegradable cleaners that remove organic growth without damaging roofing materials. After cleaning, we rinse and perform a quality check — and provide before/after photos.

Serving Tacoma, Puyallup, Lakewood, Auburn, Seattle — locally owned & operated.

FAQS

Here are answers to some common questions. 

  • Why should I clean my roof instead of replacing it?

    Regular roof cleaning removes moss, algae, and debris that can cause shingles to deteriorate early. A proper soft wash can extend your roof’s life by up to 10 years—saving you thousands compared to replacement.


  • Is soft washing safe for my roof?

    Yes, 100%. Our soft washing method uses low-pressure water and eco-friendly cleaning solutions that safely break down moss, mold, and grime without damaging shingles, flashing, or gutters.

  • How often should I have my roof cleaned?

    In the Pacific Northwest, we recommend a cleaning every 2 to 3 years, depending on shade and moisture levels around your property. Regular maintenance helps prevent moss regrowth and roof discoloration.

  • Do you offer a warranty or guarantee?

    Yes — every roof cleaning comes with a 2-year moss-free guarantee. If moss returns during that period, we’ll treat it again at no charge.

  • Will the cleaning solutions harm my landscaping or pets?

    No. We use biodegradable, eco-safe cleaning products and thoroughly rinse surrounding plants, siding, and walkways to protect your property and pets.

  • Do I need to be home during the cleaning?

    No, as long as we have access to your roof and water supply. Many homeowners schedule their cleanings while at work or running errands.

  • What areas do you serve?

    We proudly serve Tacoma, Puyallup, Lakewood, Auburn, and the greater Seattle area.
