FAQs
What areas do you serve?
We serve the greater Seattle area, including Seattle, Bothell, Kirkland, Shoreline, Lynnwood, Woodinville, Edmonds, Bellevue, Redmond, Sammamish, Mill Creek, and Mountlake Terrace. We're based in Kenmore, WA.
What does roof or gutter cleaning cost?
Asphalt roof cleaning starts at $499 and gutter cleaning starts at $250, with final pricing based on size, pitch, moss level, and access. Metal, tile, and cedar shake roofs are priced separately. Dylan will call or text after you submit the form to understand the job before giving a final quote.
Are you licensed and insured?
Yes. Seattle ProWash is fully licensed, bonded, and insured, and we carry full liability coverage for both residential and commercial properties.
What is your guarantee?
Our roof cleaning comes with a 12 month moss free guarantee. If the moss grows back within that window, we re-treat it free. We also stand behind our work with a 100 percent satisfaction money back guarantee.
Will you damage my shingles with high pressure?
No. We never use high pressure on asphalt shingles. Our soft wash process uses low pressure and specialized solutions to safely remove moss, algae, and lichen without damaging your roof or voiding warranties.
Do I need to be home during the service?
You don't need to be home. We work on the exterior only and send before and after photos when the job is complete. Just make sure we have clear access to your roof and gutters.
How soon can you schedule my service?
After you submit the form, Dylan will call or text to confirm details and provide clear pricing before you book. Scheduling depends on weather and current demand.
