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.

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.

Sean was a total pro - thorough, timely, and friendly. He took great pride in his work and offered to send us before and after photos. Thanks so much!
I was amazed how fast their moss treatment starts to work. The blow off and clean up included removal (off my property) of tree branches on the roof from the early winter storm. They won't leave the job until I'm satisfied and all my questions answered.
This is the second time we’ve used your services, and each time your work has been excellent, and your service professional. Thanks very much, Ty!
Tariq was an amazing technician. Appreciated his attention to detail and above and beyond service. Wish I'd contacted Johnny Tsunami sooner. Will be having him back for other projects in the future
Great job! We had our roof cleaned and treated, and gutters cleaned. Efficiently completed! We will be using Johnny Tsunami in the future!
Michael did a fantastic job! He kept me informed throughout the process. I highly recommend Johnny Tsunami for reliable home maintenance.We had our roof, solar panels and gutters cleaned.From estimates to job completion, everyone was professional and knowledgeable.
Jack Valdez is a lean mean cleaning machine! On his first as Lead, and single-handed at that, he did an outstanding job involving routine and advanced glass cleaning, soft washing and pressure washing. The house is transformed and ready for Spring! Jack is a hard worker and totally professional. A genuinely nice young man as well. He is clearly a future Leader in your company! Well Done!
Johnny Tsunami goes above and beyond. Service technicians are always nice and knowledgeable. Alex did a great job on pressure washing my house and cleaning the windows and gutters. No pressure tactics, and always looking out and letting me know about foreseeable problems. I truly appreciate that.
This is the second time I've used Johnny Tsunami for roof cleaning and moss removal and both times they have been top notch! HIGHLY RECOMMEND!
