Zach’s Power Washing offers roof and gutter cleaning in Olympia, WA, as well as Lacey, Tumwater and the rest of Thurston County. We soft wash your roof to kill moss, algae and lichen with no pressure on the shingles, then clean out the gutters and blow off the walkways so nothing is left behind. Booking both together gets your roof and your drainage taken care of in one visit.

Your roof and gutters work as one system. Rain runs down the shingles, into the gutters and out through the downspouts. When moss and fir needles build up on the roof, they don’t stay put. Every storm washes some of it down into the gutters, where it packs in with leaves and turns into a soggy plug.
That’s why cleaning only one of them tends to leave you with a problem. Clean the gutters but leave a mossy roof, and they start filling up again with the next big rain. Treat the roof but skip the gutters, and the moss we brush off ends up sitting in them. When we do both, roof first and gutters second, everything that comes off the roof gets cleaned out before we pack up.
It’s easier on you, too. You get one quote and one appointment instead of trying to line up two.
Here’s what we take care of when you book the two together.
Have a steep roof, a third story or a section that’s hard to reach? Mention it when you ask for a quote so we can plan for it.
Get both taken care of in one visit. Send us a message for a quote or call Zach’s Power Washing today.
It mostly comes down to how many trees are around your house. Here’s a good rule of thumb for homes in Thurston County.
Gutters: Once a year, in the fall.
Roof: Check for moss each year and have it treated when you see green starting to show.
Gutters: Twice a year, in late fall after the leaves drop and again in spring.
Roof: Plan on a moss treatment every few years, since shade helps it come back.
Gutters: 2 or 3 times a year, because needles come down in every season.
Roof: Shady roofs grow moss the fastest, so keep a close eye on it once the guarantee period is up.
After a roof treatment, the dead moss keeps coming off for 3 to 6 months. It’s a good idea to book one more gutter cleaning once the roof has cleared up, so the last of it doesn’t sit in your gutters all winter.
Gutters have one job: carry rainwater off the roof and away from the house. When they’re packed full, the water spills over the sides instead. Olympia gets around 50 inches of rain a year, so that adds up fast.
The overflow soaks fascia boards and siding, which leads to dry rot and mold. It pools along the foundation, where it can cause leaks and cracks over time. It also pounds the flower beds and landscaping below. If your gutters spill over in a heavy rain, or you can see plants growing out of them, it’s time to get them cleaned.
Late fall is when most homeowners around here think about their gutters, and for good reason. Once most of the leaves have dropped, usually by November, it’s a great time to clear everything out before the worst of the winter storms.
Spring is the other good window. It lets you clean up after a winter of wind and rain and get ahead of new moss before it takes hold. The roof treatment needs a few dry days after it goes on, so we’ll work with you on timing. If your gutters are overflowing right now, there’s no need to wait.
Here are a few photos from roof and gutter jobs around Thurston County. You can see more of our work in our project gallery.



Zach did a great job cleaning my roof and chain link fence. My house is surrounded by tall trees so the backside of my roof and my backyard fence get a lot of moss and mildew buildup… I’m happy that the moss on my roof is dead and falling away. Zach was also respectful of the plants around my home with regard to the water runoff. I will definitely hire him again.
Zach was very professional and easy to work with. I had other scheduling issues and he worked with me. The workers were very careful setting up around my house, flower beds, and garden area.
Zach’s Power Washing is a local pressure washing company in Olympia, and we clean roofs and gutters for homes and businesses throughout Thurston County.
All over town, from the Westside and Eastside to South Capitol and Cooper Point. Older neighborhoods with big firs and maples tend to fill their gutters the fastest.
We clean roofs and gutters in Lacey, WA too, including Hawks Prairie, Tanglewilde and the neighborhoods around Long Lake, Hicks Lake and Pattison Lake.
Tumwater homeowners can book us too, from Tumwater Hill and Bush Prairie to the homes near Black Lake.
Outside the city limits? We serve other parts of Thurston County as well. Call 360-915-3282 and we’ll tell you if we can get to your address.
Only need one part done, or want the rest of the house cleaned while we’re there? We can help. Thinking about whether a mossy roof is worth saving at all? Our post on is roof cleaning worth it walks through it.
Thick moss on the roof? Our soft wash moss treatment comes with a 2-year guarantee against regrowth.
Algae streaks, lichen and buildup cleaned off your roof with the same no-pressure method.
Just need the gutters done? We clean them year-round and leave your downspouts running clear.
Gentle soft washing that removes dirt, algae and stains from siding, stucco, brick, wood and vinyl.
It depends on the size and pitch of your roof, how many stories the house has, how much moss is up there and how full the gutters are. A single-story ranch with a few trees will cost less than a steep two-story home under tall firs. For an exact price, request a quote or call 360-915-3282.
The roof comes first. We brush off the big clumps of moss and treat the roof, then clean out the gutters, so whatever came down from the roof gets cleared out before we leave. Doing it the other way around just fills the clean gutters back up.
No. We soft wash roofs with a treatment that kills moss, algae and lichen, and we don’t put pressure or water flow on the shingles. Pressure washing can take years off a roof’s life and even cause leaks.
Some of it will. The treated moss dies and turns white, and over the next 3 to 6 months the wind and rain wash it off the roof, so part of it lands in the gutters. Many homeowners book one more gutter cleaning once the roof has cleared up. After that, our 2-year guarantee means no new moss grows back on the roof for 2 years.
At least once a year, usually in the fall. If you have trees close to the house, plan on twice a year, in late fall and again in spring. Homes under tall firs or cedars often need it 2 or 3 times a year, because needles come down in every season.
Yes. If you only need one, take a look at our pages for roof cleaning in Olympia and gutter cleaning in Olympia. For heavy moss, our roof moss removal service is the best fit.
Yes. Along with Olympia, we clean roofs and gutters in Lacey, Tumwater and other parts of Thurston County. Call 360-915-3282 if you’d like to check whether we cover your address.
Gutter cleaning is available year-round, so you don’t have to wait for summer if they’re overflowing now. Roof treatments need a stretch of dry weather after they go on, so we’ll plan that part around the forecast.
Every house is a little different. Call us or send a message and we’ll talk through what’s going on with your roof and gutters.
