The Real Cost of Waiting

Your Roof Is Losing Years Right Now

The Puget Sound gets 72+ inches of rain per year with mild temps that give moss a 12-month growing season. Every month you wait, the damage compounds.

Our Process

5 Steps. No Damage. Guaranteed Results.

Our soft-wash system removes organic growth at the root — no high-pressure blasting that strips granules or voids warranties.

1
Roof Inspection
We walk your roof and identify damage, vulnerable areas, and growth type before any cleaning begins.
2
Landscape Protection
All plants, siding, and sensitive areas below the roofline are pre-soaked and covered before treatment.
3
Soft-Wash Application
Biodegradable solution applied at low pressure — kills moss and algae at the root. Zero high-pressure blasting.
4
Dwell, Rinse & Hand-Remove
Solution fully neutralizes all organic growth, then is gently rinsed. Heavy moss is hand-removed where needed.
5
Zinc Prevention Treatment
A zinc-based treatment inhibits regrowth and extends results 12–18 months in typical PNW conditions.

Real Results. Real Homeowners.

★★★★★

“Our driveway looked brand new — we couldn't believe the difference. The crew was professional, on time, and cleaned up after themselves. Neighbors have already asked for the number.”

★★★★★

“Had moss covering half our roof. Velocity removed everything without any damage to the shingles. Six months later it's still clean. Worth every penny compared to what a new roof would cost.”

KT

Issaquah, WA
★★★★★

“We hired them before listing our home. The soft wash made the siding look 10 years newer. Our realtor said it was the best pre-listing investment we made. Sold in four days.”

Common Questions

Everything You Want
to Know Before You Book

Will roof cleaning void my warranty?
+
No. Our soft-wash low-pressure process is manufacturer-approved and will not void your roofing warranty. High-pressure washing can void warranties — we never use it.
Is $299 the final price?
+
$299 is our starting price for standard residential roofs. You'll receive an exact quote after your free estimate — no surprises, no pressure to book on the spot.
How long do the results last?
+
With our zinc prevention treatment, results typically last 12–18 months in Puget Sound conditions. We recommend a cleaning cycle of 1–3 years depending on shade and tree coverage.
Is the cleaning solution safe for plants and pets?
+
Yes. We use biodegradable, eco-safe solutions and pre-soak and cover all landscaping. We'll let you know when it's safe for pets to return — typically within a few hours.
How soon can you come out?
+
We serve Snoqualmie, Issaquah, Sammamish, Bellevue, Kirkland and surrounding communities. Scheduling is typically 3–7 business days from your estimate.
