Johnny Tsunami Answers The Most Common Exterior Cleaning FAQs

Roof cleaning costs in Washington typically range from $450 to $1,200 depending on your roof’s size, pitch, material, and how much moss or debris is present. At Johnny Tsunami, our average roof cleaning runs around $700 for standard residential properties. This cost ensures that your roof receives the right treatment, prolonging its life and improving your home’s overall curb appeal.
What affects pricing:

• Square footage
• Roof complexity and steepness
• Moss buildup severity
• Accessibility (multi-story homes, landscaping)

We offer transparent estimates and bundled pricing if combined with gutter or siding cleaning. Our technicians will walk you through the scope, explain the pricing, and deliver a clear estimate. If you’re in Kitsap County, King County, or surrounding counties, contact us for a custom quote tailored to your property’s unique needs

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.

The PNW is a moss paradise:

• Constant rain and cool temps

• Leaves and needles collecting moisture

Unchecked moss can damage shingles, trap moisture, and lead to leaks. Cleaning it off and applying preventative treatment is the smartest way to protect your roof and gutters from long-term damage.
