Moss Removal pricing depends on several key variables:

  • Roof condition (severe moss = more labor and chemical application)
  • Treatment area (partial or full roof coverage)
  • Type of roof (metal, composite, tile — all require different approaches)
  • Height, pitch, and overall accessibility

Soft Washing pricing is based on the total surface area cleaned and whether you’re treating siding, driveways, patios, fences, or concrete surfaces. Our process includes a low-pressure application of eco-safe solution, rinse, and optional preventative Moss Control. We’ll inspect your property and help prioritize what services bring the best ROI.

Most single-family homes pay between $200 and $350 for a full Gutter Cleaning service. This includes removing debris, flushing downspouts, inspecting flow, and cleaning the exterior of the gutters (if requested). Larger homes, multi-story buildings, or properties surrounded by tall trees and heavy debris may cost more.

We recommend cleaning your gutters at least twice a year — especially in spring and fall — to prevent clogs, water damage, and costly repairs. Overflowing gutters can compromise your roof, siding, and foundation, so staying ahead with proactive care is essential.

Yes! Johnny Tsunami offers bundled service packages that reduce overall cost and increase convenience. Common bundles include:

  • Roof + Gutter Cleaning

  • Whole-home Exterior Clean + Windows + Decks

Bundling different exterior cleaning services saves you money and ensures a more efficient service visit. Our teams coordinate the work across services, saving you time and, hassle, and giving your entire home a refreshed, professional look in one go. Bundle and save while maximizing your property’s appeal.

Our MX Plan is a hands-off, peace-of-mind program for proactive homeowners. We tailor each plan to your property’s layout, tree coverage, and roof condition. Services can include:

  • Annual or biannual soft wash roof treatments
  • Spring and fall gutter cleanings
  • Algae and moss prevention services
  • Siding wash-downs and driveway treatments
  • Window cleaning add-ons

Members enjoy priority scheduling, 15% off services, and regular reminders so you never miss essential maintenance. Great for busy homeowners, landlords, and HOAs.

Eventually — yes. But our professional treatment significantly delays regrowth. Most roofs stay clean for 12–18 months depending on your tree coverage, weather exposure, and drainage.

We recommend an annual maintenance plan for moss prevention, gutter flow control, and touch-up treatments. We also provide guidance on trimming overhanging trees, clearing roof valleys, and keeping surfaces dry to slow moss growth.

One-time cleaning solves the immediate problem. Maintenance plans prevent the problem from coming back.

Benefits of our MX Plans:

  • Lower annual cost
  • Auto-reminders and scheduling
  • Priority booking before the busy season
  • Long-term savings on repairs and replacements

Homeowners who join our plans stay cleaner, longer — and save big over time.

Had roofs/gutters cleaned & washed. Also, had additional screen reinforcement around chimney top to prevent critters from coming down the flue. Shawn & Daryl started the job on the first day, they did a fantastic job in spite of not having an optimal ladder for the job site. Second day, Gavin & Daryl came out, they did a fantastic job in spite of not having an optimal ladder. Third day, Gavin came back with a taller ladder to finish the job and install additional chimney screen. He did an amazing job with everything; he’s conscientious and thorough. And as requested, he sent us LOTS of photos afterwards.
We are happy with the service the guys provided. A shout out to Gavin, Shawn & Daryl for working so hard, and a job well done!

Considering the torrential rain, Gavin was very good at cleaning our gutters and roof. He also cleaned up all debris that came off roof during the rain. Time will tell how it went, but I am very pleased so far.

Dalton and Quentin soft washed the roof on our home and shed. They also blew debris from another shed that wasn’t even part of the job, as well as cleaned our windows. They were friendly, knowledgeable and professional. We highly recommend their work! We also want to say that JP, who came out to do the estimate, was also very friendly and professional in working with us to get the best roof treatment within our budget. Great experience all around!

Ty Jensen and his colleague, Dalton, did an outstanding job cleaning my roof and prepping it to control future moss growth. I am very grateful for their diligent and hard work and for explaining exactly what work they performed today. They are excellent workers employed by an excellent company. I have entrusted Johnny Tsunami to maintain my roof so that it outlives me. Thank you for such a great service.

Merrill did an excellent cleaning job on our roof, today. He is a great service tech representative for Johnny Tsunami of Silverdale, WA. Merrill was punctual, very informative about the process and methodical in his work; all traits which put me at ease and made me feel I was getting very good value (in tapping my limited resources) for services rendered. Thanks, Merrill!

Fair price. Very knowledgeable technician. Superb attention to detail and very helpful suggestions. I would hire this technician (Merrill) any day of the week for virtually any job around the house. He's that good.
