Roof Moss Removal
Moss might seem harmless at first — but left untreated, it quietly compromises your roof, holds moisture against your shingles, and accelerates decay. Removing it the right way takes more than just a broom and a Saturday afternoon. It takes the right tools, a gentle touch, and the experience to treat your roof without causing further damage. That’s where we come in.
Whether you’ve got light moss along the eaves or a thick green carpet climbing across your entire roofline, we customize our approach to protect your home while restoring its integrity. You tell us your concerns — and we’ll deliver safe, effective moss removal and treatment with care, attention, and long-term protection in mind.
Moss Assessment
Our process begins with a detailed, on-site inspection of your entire roof. We assess the extent of moss growth, identify any existing roof vulnerabilities, and ensure safe access. This critical first step allows us to tailor the most effective and safest removal strategy for your specific roofing material.
Manual Removal
We meticulously remove moss using specialized tools and techniques, primarily by hand. This gentle approach carefully removes moss buildup without damaging your shingles or compromising your roof's integrity. We take our time and prioritize preserving your roof's lifespan over more common, damaging methods.
Grounds Clean Up
We perform a thorough clean up of the grounds, ensuring no moss is left on your decks, walkways or patios. Our commitment is to leave your property cleaner than we found it. After this, we recommend Gutter Cleaning and Zinc Moss Treatment as essential steps to ensure a complete service.
Whether your home is near a greenbelt in West Seattle, on the water in Edmonds, or perched beneath Maples and Pines on Beacon Hill, our meticulous moss removal and effective treatments are designed to safeguard your roof from deterioration, and keep your most valuable investment protected from the top down.
At Husser Window and Gutter Cleaning, our comprehensive moss management service is a cornerstone of proactive exterior maintenance, addressing critical challenges faced by homes across the Greater Seattle Area. We help you preserve your roof's structural health, prevent costly damage, and maintain its pristine condition.
Extend the life of your roof, boost curb appeal, and ensure the integrity of your home!
Answering Our Recent Customer Questions about Moss Removal
Asked on 10-27-2026: How do you remove moss without damaging the roof shingles?
Answer: We manually remove the moss using a brush. It's a more labor-intensive process to brush by hand, but it's also the least abrasive method available, and our goal is to gently brush away the moss without dislodging the protective gravel and granules from your composite shingles. Moss removal is a balance between removing overgrowth and also ensuring your roof is kept in peak shape.
Asked on 10-24-2026: What happens if moss is growing directly on top of the shingles?
Answer: It's important to be careful when performing horizontal scrubbing on top of shingles, and we use a less abrasive brush to remove as much moss as we safely can (typically about 80% of it, sometimes up to 90% if the moss type is particularly straightforward to remove). Because scraping off 100% of the moss by hand would also strip away the shingle's granules, we leave the starchiest, strongest small bits behind and apply a specialized moss treatment (sodium percarbonate) to kill whatever remains.
Asked on 10-29-2026: Why is it so important to avoid removing the shingle granules?
Answer: If too much of the composite granules are removed during the removal process, the shingles will become brittle over time and begin to crack. This is extremely important to avoid! Removing the protective layer of the shingles will reduce your roof's integrity, which is the opposite goal of a moss removal. As we've mentioned, it takes a lot of careful consideration to appropriately remove the right amount of moss while never going "over the line" with how much we actually affect the roof itself. Our combination of gentle brushing and chemical treatment ensures the moss dies without compromising the integrity of your roof.
Asked on 10-16-2026: How long does the moss treatment take to work?
Answer: Sodium Percarbonate begins taking effect almost immediately within a day or two, and continues to work for some time. It's ideally formulated to our weather i Seattle, as it reacts with moisture and water on the roof. It soaks in quickly, and you should see all the remaining moss die within a week or two. There can be a small amount of discoloration for a few days, but this is temporary and goes away when the moss finally dies at the root and falls off.
Asked on 9-22-2026: Do you come back later to brush off the dead moss?
Answer: Typically, no, because we brush off the majority of the moss before applying the treatment, and so the small amount that remains to die off isn't significant enough to require a second round of brushing. In the event that the removal doesn't take well enough - which has never happened to us - we're always willing to return and touch up work that isn't perfect.
Asked on 8-20-2026: What if my roof is completely covered in thick moss?
Answer: Even for very significant coverage - when moss is extreme - we'll manually brush off as much as we can without damaging the roof as usual. But then we may implement a more aggressive treatment regimen. For example, we will apply a treatment immediately and may recommend a follow-up application at the end of the winter if the moss attempts to grow back, or even recommend 3x per year moss treatment and gutter cleaning for roofs that are constantly bombarded with leaves, needles and moss spores.
Asked on 7-15-2026: Do you also clean the gutters after you remove all the dead moss, and is that included in the service?
Answer: Absolutely, yes. We always clean the gutters directly after the moss removal, and that is included in our visit. We used to charge separately for gutter cleaning, separate from moss removals. But we learned over the years that it's always critical to combine these services, since the dead moss naturally falls into the gutters and downspouts after a removal. We created one, comprehensive service that ensures your roof and gutters are both left completely functional and clean when we leave your property. This way you don't have to worry about it for many months or even over a year, and when the rains start you can rest easy knowing that everything above your roofline is functional.
Gutter Cleaning
Gutter cleaning might seem simple — but protecting your home from water damage takes more than just removing leaves and branches. Gutters and downspouts require the right tools, safe access, and a trained eye to ensure water flows freely and nothing is overlooked.
Whether you have a multi-story roofline, a sprawling ranch home with a torch-down roof & catch system, an older home with fragile seams, or just a gutter system that hasn't been touched in years, we tailor our approach to match your property’s unique needs. We'll take great care with your gutters — and we’ll exceed your expectations with efficiency, and attention to detail.
Inspection & Setup
Our process begins with a thorough, top-to-bottom inspection of your entire gutter and downspout system. Our expert technicians identify existing clogs, potential problem areas, and ensure safe access to the roof, prioritizing your property's integrity and our team's safety.
Debris Removal
We meticulously remove all accumulated leaves, pine needles, and other organic debris from inside your gutters. This vital step is typically done by hand or with specialized tools to ensure gutters are clear without causing damage, preventing clogs that lead to water overflow.
Flow Verification
Once the gutters are clear, we ensure your downspouts are completely free of blockages above ground. We either flush them with water or use high-powered air to dislodge any packed debris, safeguarding your home against costly water damage.
Whether your property is surrounded by towering fir trees in Shoreline, epic Madrones in Madrona, or prolific Dogwoods in West Seattle, our meticulous gutter cleaning ensures your home is protected from the roof down, safeguarding your most valuable investment.
At Husser Window and Gutter Cleaning, our expert gutter cleaning service is a cornerstone of comprehensive exterior maintenance, addressing critical challenges faced by homes across the Greater Seattle Area. We help you preserve your property's structural health, prevent costly water damage, and maintain its pristine condition, year-round.

Annual Maintenance Plans for the Greater Seattle Area and Eastside
In the Pacific Northwest, relying on one-time cleanings or reacting only to visible damage is insufficient to truly protect your roof and gutter system's longevity. Neglecting annual maintenance can lead to hidden issues, accelerated deterioration, and expensive emergency repairs that far outweigh the cost of prevention - like needing to purchase a new roof earlier than expected!
Husser Window and Gutter Cleaning's comprehensive Annual Roof & Gutter Maintenance Plan provides year-round peace of mind and a substantial savings on multiple separate services. Our expert, comprehensive service includes a precise and thorough spot check and partial removal of any new moss regrowth, a full gutter cleaning service, and Sodium Percarbonate chemical treatment. We perform a full status report on the condition of your roof materials and entire gutter system. This proactive approach ensures your roof sheds water efficiently, remains free of damaging growth, and significantly extends the lifespan of your property's most critical defenses.
Annual Roof & Gutter Maintenance Plans start at $550 per year plus applicable city and state tax. Ask our friendly staff about an estimate for your annual service plan.

Commonly Asked Questions About Gutter and Roof Cleaning from Husser Window and Gutter Cleaning Customers in Seattle and the Eastside
What's the average cost for professional gutter cleaning in Seattle?
The average cost for professional gutter cleaning in the Seattle area is a starting point of $200 - $300. However, some properties are definitely outside of that range. Husser Window and Gutter Cleaning provides a comprehensive, personalized quote for every property before any work begins, so you always know the exact price.
Factors that can affect the final price include:
-
Home size (square footage and number of stories)
-
Roof type (metal, wood, or tile)
-
Density of debris from nearby trees.
What's the difference between Roof Cleaning and Moss Removal?
Roof Cleaning and Moss Removal are very different, but both are necessary. Staggering them is a smart choice to keep your roof in top shape. Cleaning your gutters and roof annually - and applying a moss treatment - is the best way to maintain its integrity, and ensures your roof is fully protected and maintains its health year-round.
-
Roof Cleaning is a manual process that involves removing all the debris—leaves, pine needles, and sticks—from your roof's surface. This is done to prevent moisture from getting trapped and causing damage and is recommended every year.
-
A gentle Moss Removal is recommended every 4-5 years to eliminate any regrowth that might compromise your roof's integrity over time.
Can you soft wash my shingle roof?
No. While some companies may use this approach, pressure washing on composite rooftops can easily create hairline cracks and cause long-term, insidious damage to your roof.
Husser Window and Gutter Cleaning never uses power washers on composite roofs, even with low-pressure settings. Husser’s method is designed to protect your property and ensure a safe, effective clean. Instead, they recommend a manual soft scrub method with angled brushes to carefully remove moss and debris.
This approach is designed to:
-
Protect the integrity of your roof: By avoiding risky methods, they ensure that no damage is done to your roof.
-
Remove only the moss: A slow, effective approach avoids stripping away essential layers of your roofing material.
-
Extend the life of your roof: Husser’s gentle, effective methods preserve your roof's lifespan rather than diminish it. The goal is to safely and professionally remove the moss and protect your property from costly damage.
Can you clean a wood/cedar shake roof?
Yes. Husser Window and Gutter Cleaning does clean wood/cedar shake roofs, but only by hand. Even low-pressure washing can force water between the shakes, leading to premature splitting, decay, and irreversible damage. This service takes longer than a typical roof cleaning, but the investment is worth it: you receive a safe, effective cleaning that actively extends the life of your wood roof without risking costly damage.
Husser Window and Gutter Cleaning's method is a precise, time-intensive, dry approach:
-
Manual Debris Removal: They carefully use brooms, leaf blowers, and specialized hand tools to gently remove debris, pine needles, and loose moss.
-
Protection First: Their primary focus is the preservation of the wood. This non-abrasive approach is specifically designed to avoid scarring the sensitive cedar or forcing water into the shake layers.
Do you clean metal or concrete roofs?
Husser Window and Gutter Cleaning does clean metal and concrete roofs, and they state that these are the only times they use a soft wash process on a roof. These highly durable materials can withstand water-based cleaning, and soft washing is the safest and most effective method for removing moss, rust, and heavy environmental staining from metal or concrete roofs without causing abrasion or wear.
Husser Window and Gutter Cleaning’s soft wash process involves:
-
Customized Solution: Applying a cleaning solution tailored to the specific material (metal or concrete) to safely kill organic growth like moss and algae at the root.
-
Low-Pressure Rinse: Rinsing the roof using low-pressure equipment, which is highly effective on these hard surfaces but keeps water from forcing its way into complex joints or underneath flashings.
For any other roofing material (like wood shake or composite shingles), they will use a proprietary manual or dry-cleaning method to ensure maximum material preservation.
Can I just clean my own gutters?
Although it’s ultimately your choice, hiring a professional is recommended as a safer, more effective, and ultimately less costly option in the long run. Hiring Husser Window and Gutter Cleaning saves you the time, the mess, and the physical risk, while guaranteeing a complete and correctly functioning gutter system.
There are Three Main Reasons to Hire a Professional Gutter Cleaner:
1. Safety is Paramount. Gutter cleaning involves working at significant heights on ladders, often on uneven or wet ground. Falls are a major cause of household injury. Husser’s crew is expertly trained, insured, and equipped with the proper safety gear to eliminate that risk for you.
2. It Protects Your Property. Professionals like Husser Window and Gutter Cleaning know how to work around downspouts, flashing, and roofing materials without causing damage. They can clear debris without scraping or bending gutters, and can spot minor issues (like loose joints or damaged seals) before they turn into major leaks.
3. You Get a Complete, Guaranteed Clean: The team at Husser Window and Gutter Cleaning uses specialized tools to ensure all downspouts are fully flushed and cleared of compact, hidden debris. This ensures water flows correctly. Their work is guaranteed, saving you the hassle of climbing a ladder if anything is missed.
How long does a typical gutter cleaning service take?
A typical gutter cleaning service averages 1-3 hours, but every home is different. Larger homes or those with significant debris may take longer.
Husser Window and Gutter Cleaning makes the process hassle-free for you.
-
You do not need to be home for the service. Their crews can complete the job entirely from the exterior.
-
The technicians at Husser Window and Gutter Cleaning can take before-and-after photos for your records, on request.
The goal is to provide a comprehensive, professional service that you don't have to worry about.
Are you licensed and insured for roof and gutter cleaning in Seattle?
Yes, Husser Window and Gutter Cleaning is a fully licensed and insured contractor in WA State. For your protection and your peace of mind, they're fully licensed and covered with comprehensive liability insurance. With 18 years of experience and a perfect safety record, you can trust that your home is in safe hands.
Choosing a licensed and insured professional is the best way to ensure your property is protected and the work is done safely and correctly.
Do you offer maintenance plans for gutter cleaning and roof cleaning in Seattle?

How do you clean make sure the downspouts aren't clogged after cleaning my gutters?
The team at Husser Window and Gutter Cleaning follows a meticulous three-step process to ensure water flows freely from your gutters into the drainage system. If a deep clog is identified, we will recommend you contact a rooter or specialized drainage professional, ensuring you know exactly where the blockage is located so you can get it fixed quickly:
1. Elbow and Roofline Clearance: After manually scooping the main gutter troughs, we target the most common blockage points—the elbows and initial bends near the roofline. We use hand tools, small plumbing augers, and directed hose pressure to physically clear any compacted leaves or debris stuck in these tight areas.
2. Full System Flush: Once the gutter and elbows are clear, we flush the entire system with a steady stream of water to confirm that all channels are running smoothly.
3. Below-Ground Clog Notification: We can clear all debris at the roofline and immediately below, but we cannot clean below-ground drain pipes. If our flush test reveals a slow-draining or backed-up system—indicating a deeper, pre-existing clog (often caused by roots or compressed soil/sludge)—we immediately notify you.
What's the best time to clean gutters in Seattle?
For most homes in the Greater Seattle Area, it’s recommended to schedule a gutter cleaning twice a year: once in the late spring or early summer, and again in the fall before the heavy rains begin. However, homes surrounded by fir trees have unique needs. Don’t wait for a clog to happen! A proactive service helps homeowners like you prevent costly water damage and keeps your property safe, no matter what kind of foliage is nearby.
Because these trees shed needles year-round, we highly recommend a late summer and late fall gutter cleaning schedule to prevent heavy buildup and avoid water damage.
Is your moss treatment safe for my yard and my pets?
Husser Window and Gutter Cleaning uses an eco-friendly Sodium Percarbonate solution, which is a biodegradable alternative to harsher chemicals. It is widely considered safe for your roof, landscape, and the environment.
This superior solution is non-toxic and safer for children, pets, gardens, and the delicate Pacific Northwest environment. When you choose Husser Window and Gutter Cleaning, you're protecting your home and helping keep our beautiful city free of unnecessary pollutants.
This environmentally safe, professional treatment is designed to:
-
Inhibit moss growth without harming your roof's integrity.
-
Break down into naturally occurring compounds that are safe for your plants and small animals.
While the solution is eco-friendly, it is still important to keep pets, children and small animals away from the work area during the treatment and until the solution is fully dry.
