Why Our Method is Different

Many companies use "one-size-fits-all" pressure washing, which can void your roof's warranty. Chinook Services prioritizes chemistry over pressure. By using manufacturer-approved soft washing, we protect your investment while delivering a 100% kill rate on moss and algae.

Premium Asphalt Shingle Cleaning Process (our most popular roof service)

While asphalt shingles are the most common roof type in the Greater Seattle area, they are also the most delicate and require expert care. To guarantee the highest standards of safety and quality, Chinook Services always deploys a professional 2-man crew to every job. Our team follows a meticulous three-step restoration process designed to protect your home’s integrity, all backed by our industry-leading 5-year no-moss warranty.

1. Gentle Debris Removal & Ground Cleanup

We begin with a professional roof blow using high-volume, low-pressure leaf blowers. This safely removes pine needles, leaves, and loose debris without disturbing the protective granules on your shingles. Once the roof is clear, we perform a thorough ground cleanup to leave your property spotless.

2. Comprehensive Gutter & Downspout Service

A clean roof needs functional drainage. We hand-clean the interior of your gutters and downspouts, followed by a full system flush using a garden hose. This tests the flow and ensures your drainage system is ready for the next Pacific Northwest rainstorm. (Note: Interior cleaning and flow testing included; optional exterior gutter face cleaning available).

3. Low-Pressure Soft Wash Application

The final step is the application of our specialized soft wash solution. Using low-pressure equipment, we treat the shingles to instantly kill all moss, algae, and lichen at the root. We never use high pressure, ensuring we stay within manufacturer warranty guidelines.

Five Year No Moss Warranty

Guaranteed Moss Removal in Snohomish & King County Our 5-Year No Moss Warranty is the simplest in the industry. Once we've initiated the moss-kill process on your asphalt shingles, we guarantee results. If new green moss grows back within five years, our team will return to perform a follow-up soft wash treatment at no cost to you. We believe in our low-pressure cleaning process, and we make sure your roof stays protected.

Deluxe Roof Cleaning Package

Our Deluxe Package is the gold standard for asphalt shingle care. If you have a different roofing material, our experts will review your property to provide a custom-tailored cleaning solution.

However, if you have an asphalt shingled roof—the most common type in the Puget Sound—the following is our specialized Deluxe Roof Cleaning procedure:

Step 1: Gentle Roof Blow & Ground Cleanup

Our technicians perform a meticulous low-pressure roof blow to remove pine needles, leaves, and loose organic debris. This technique is designed to be effective without disturbing the protective mineral granules on your asphalt shingles. To ensure your property looks better than when we arrived, we include a comprehensive ground cleanup of all fallen roof debris from your walkways, decks, and landscaping.

Step 2: Interior Gutter Service & Flow Testing

A clean roof is only effective if the water has somewhere to go. We manually hand-clean all gutters and downspouts, removing every handful of sludge and debris. Once cleared, we perform a full system flush using garden hose water to verify perfect drainage and flow throughout your entire gutter system.

Pro Tip: While we ensure the inside of your gutters are spotless and functional, we also offer an optional Gutter Front/Exterior cleaning to remove "tiger stripes" and restore their outward shine. Also known as gutter whittening.
