Roof cleaning & moss removal

Roof cleaning and moss removal in Seattle

We never pressure wash a roof. You get a gentle no-pressure treatment with eco-friendly compounds that kills the moss at the root and protects your shingles. Done right, it lifts years of green growth and adds years of life to the roof you already have.

  • No pressure on roofs, ever, so shingles stay intact
  • Eco-friendly compounds that kill moss at the root
  • Protects the granules that keep your roof watertight
  • Adds years of life and can delay a costly replacement
  • Plant-safe rinses and careful runoff management

Watch it work

A gentle rinse, never pressure. The moss loses anyway.

Why gentle wins

Why a no-pressure wash protects your roof

High pressure tears up shingles and voids warranties. A gentle treatment does the work safely.

No pressure, no damage

Pressure strips the protective granules off shingles. Our gentle wash cleans without touching them.

Kills moss at the root

Eco-friendly compounds treat the moss where it grows, so it does not just come back next month.

Adds years to your roof

Clearing moss before it lifts shingles protects the roof you have and can put off a full replacement.

Reviews

What Seattle homeowners say

Real reviews from Seattle homeowners and small businesses.

  • My old shingle roof was looking pretty bad and I was considering a full replacement, but I was blown away by what Brian and his team did at a fraction of the cost of a roof replacement. They use a gentle wash, no power washing, with environmentally friendly compounds. I won't need a new roof for another 5 years.

  • Seattle Suds did an awesome job pressure washing our driveway, sidewalk, and front steps. The owner was super timely, really knowledgeable, and paid close attention to detail. With two little kids at home, it is such a relief to hire someone we can trust.

  • I am absolutely blown away by the incredible job Seattle Suds did on my house. Their communication was prompt, professional, and clearly explained the process and pricing. My siding, driveway, and patio were looking grimy after years, but now they look brand new.

FAQ

Roof cleaning and moss removal questions

What to expect for moss removal and roof cleaning in Seattle.

Will roof cleaning damage my shingles?
No. We never pressure wash a roof. You get a gentle no-pressure treatment with eco-friendly compounds, so the shingles and their protective granules stay intact.
Why is moss bad for my roof?
Moss holds moisture against the roof and works its way under shingles, lifting and cracking them over time. That traps water, rots the deck below, and shortens the life of the whole roof. Clearing it early protects what you have.
How long until the moss comes back?
Because we treat the moss at the root rather than just scraping it off, results last. In our damp Seattle climate, a periodic touch-up keeps a north-facing or shaded roof clear. We will tell you what to expect for your roof.
Can roof cleaning really save me from a replacement?
It often buys you years. Many roofs that look ready for replacement still have plenty of life once the moss is gone. We are honest about what a clean can and cannot do before we start.
Do you clean gutters too?
Yes. Moss and roof debris tend to wash straight into the gutters, so it is a natural pairing. Ask us and we will quote your roof and gutters together.
What if it rains?
This is Seattle, so a little drizzle never stops us. Light rain is fine for most work. For heavy rain or high winds, we reschedule at no cost.
