The Cost of Waiting vs. The Peace of Mind We Deliver
Moss actively destroys your roof. Here's what happens when you delay.
The Cost of Waiting
Years of moss damage and neglect
- Moss lifts shingles creating entry points for water damage
- Trapped moisture accelerates wood rot & structural decay
- Voided warranties when maintenance is neglected
- Insurance trouble — carriers increasingly flag visible moss from aerial photos, and it can mean a fix-it notice or non-renewal
- $10,000-$30,000 roof replacement vs. $499-$1,500 cleaning (most homes)
Peace of Mind We Deliver
Professional cleaning results that last
- Extend your roof's lifespan 10–15 years with proper moss treatment
- Boost curb appeal. Most homeowners notice the difference from the street.
- 12-month moss-free guarantee. If it grows back, we re-treat free.
12-Month Moss-Free Guarantee

Meet Dylan, Your Local Owner
I'm Dylan, based right here in Kenmore. I started Seattle ProWash in 2022 because maintaining your home is the single best ROI you can get on home improvement, period. A new roof costs $20,000 or more. Cleaning yours costs a small fraction of that.
"My goal on every job is to do it well enough that you call me back next year."
