When homeowners search for roof cleaning near me, roof moss removal in Seattle or gutter cleaning in Bellevue, they are usually looking up at the same thing: thick green moss along the shady side of the roof, black streaks running down the shingles and gutters packed with needles, leaves and moss clumps. Deep Water Pressure Washing clears it all away and protects your roof from the damage moss leaves behind.
Moss is not just a cosmetic problem. Its roots work under shingle edges and shakes, hold water against the roof and lift the layers that keep rain out. Our roof cleaning and moss removal takes the moss off by hand where it is thick, then uses a gentle, low-pressure soft wash treatment that kills the spores and algae that are left. The result is a cleaner roof that stays clean longer, without the granule loss and broken shingles that blasting a roof with high pressure can cause.
The older homes of Ballard, Fremont, Queen Anne, Madison Park and Washington Park sit under mature maples, cedars and firs that shade roofs and fill gutters every year. North-facing slopes barely dry out between rains, so moss spreads quickly across shingles and cedar shakes. We clear the moss, treat the roof and flush the gutters so water flows where it should.
In Somerset, Bridle Trails, Lakemont and Newport Hills, large homes with steep pitches and tall evergreens collect moss and needles on every valley and ridge. Our crews work with safety harnesses and roof-safe methods, so even big, complex roofs get a careful, complete clean.
Waterfront estates in Medina, Hunts Point and Yarrow Point, the hilltop homes of Clyde Hill and West Bellevue, and the heavily wooded lots of Mercer Island and Sammamish sit under tall firs and cedars that shade roofs and fill gutters all year. Many of these homes have cedar shake, tile or high-end composite roofs, and we clean each one with the method made for that material.
Education Hill, Grass Lawn, Overlake and Redmond Ridge homes live among towering firs that drop needles and cones all year. Gutters clog fast, downspouts back up and moss starts where debris piles up. Regular roof and gutter cleaning keeps newer roofs looking new and helps older roofs last.
We also clean roofs and gutters for HOAs, apartment communities and commercial buildings across all three cities, with lift access for taller buildings.

No two roofs are built the same, and no two should be cleaned the same way. The wrong pressure or the wrong solution can strip granules, split shakes or crack tiles, which is why every roof we clean starts with a look at the material, its age and how much growth has taken hold.
The Puget Sound climate keeps roofs damp for much of the year, while tall trees add shade, needles and leaves. That mix feeds moss, algae and lichen on the roof and fills gutters with debris. Our process clears all of it and treats the roof so growth stays away longer.
We safely clean nearly every type of roof and gutter, including:
Every job is tailored to your roof’s material, pitch, sun exposure and level of growth, so you get the safest and most effective clean possible.

With routine roof and gutter cleaning, your home stays drier, cleaner and better protected through every season in the Puget Sound.

Honest answers about keeping your roof and gutters healthy in the Pacific Northwest climate.
Every roof is different, so the price depends on the size and pitch of the roof, the roofing material, how much moss has built up and whether gutter cleaning is added. Deep Water keeps pricing affordable and upfront with no hidden fees, and every job starts with a free, no-obligation estimate so you know exactly what you are paying before we begin.
Moss loves shade and moisture, and Seattle, Bellevue and Redmond have plenty of both. Marine air, frequent rain and tall firs and cedars keep roofs damp, especially on north-facing slopes. Needles and leaves trap even more water. Our moss removal clears the growth and treats the roof so it takes much longer to return.
Yes. Moss roots work under shingle edges and shakes, lift them and hold water against the roof deck. Over time that can lead to leaks, rot and a roof that wears out years early. Removing moss early is far more affordable than repairing the damage it causes.
Not with the right method. We clean asphalt shingles with low pressure and roof-safe solutions that kill moss and algae without stripping the protective granules. Thick moss is removed by hand first, so we never have to blast the roof to get it clean.
Most homes in the Seattle area need gutter cleaning once or twice a year, usually after the spring pollen and again after the fall leaves and needles. Roofs typically need moss removal every two to three years, or sooner under heavy tree cover. We can set up a simple plan so you never have to keep track.
Yes. Cedar shakes are cleaned with a gentle, wood-safe process that removes moss, algae and gray weathering without splitting or loosening the shakes. Many older homes in Ballard, Queen Anne and Bellevue still have cedar roofs, and we give them the care they need.
Yes. We clear gutters by hand, bag and remove the needles, leaves and moss, flush the downspouts and check that water drains freely. We can also wash the outside of the gutters to remove the black streaks that run down the faces.
Yes. We clean roofs and gutters for apartment communities, HOAs, hotels and commercial buildings across Seattle, Bellevue and Redmond, using lifts and safety equipment for taller buildings. We schedule around your tenants and business hours.
