Applying our specialized soft wash roof treatment to a local home. This process kills 100% of moss instantly without the need for damaging high pressure, scraping, or aggressive brushing.
Asphalt shingles are the most common roofing material in the Puget Sound, and they are highly susceptible to moss damage. Our process is designed for maximum protection:
-
Debris Removal: A standard professional roof blow to remove needles, leaves, and loose organic matter.
-
Safe Moss Removal: We use a specific, low-pressure soft wash application that kills 100% of moss on contact.
-
No Damage: Our method avoids aggressive brushing or high pressure, preserving the shingles' protective granules.
-
5-Year No-Moss Warranty: We are so confident in our soft wash treatment that we offer a 5-year warranty against new moss growth.
Safe low pressure metal roof cleaning service using soft wash methods
Metal roofs are durable, but they often collect fine debris and "organics" (algae and moss) that make the surface look aged and dull.
-
Scientific Cleaning: We use the correct chemistry to break the bond between the metal and the organic growth.
-
Low-Pressure Disinfectant: Our specialized solution kills and releases algae and moss.
-
Rinse to New: A gentle, low-pressure rinse removes all residue, making your metal roof look brand new without denting or scratching the panels.
Tile Roof Cleaning
Tile roofs require a delicate touch to avoid cracking. We never use high pressure, which can damage the tile surface and underlayment.
-
Soft Wash Injection: We apply a disinfecting soft wash that kills all algae and moss on contact.
-
Low-Pressure Rinse: We remove fine debris and organic stains, restoring the vibrant look of your tile.
Flat roof cleaning including debris sweeping, drain clearing/testing/ and organic removal of algae and moss using low safe pressure
Flat roofs are prone to standing water and organic buildup ("the green stuff"). We offer specialized care for both Residential and Commercial flat roofs:
-
Debris Management: Thorough sweeping and gathering of all surface debris.
-
Drainage Testing: We test all roof drains to ensure your system is shedding water properly.
-
Optional Low-Pressure Scrub: For heavy organic buildup, we offer a specialized scrub to restore the TPO or membrane surface.

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.
Tips on Roof Cleaning
We also provide helpful tips for homeowners on roof maintenance. As an example, we have helped hundreds of homeowners with maintenance plans.

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.
