Professional Roof Cleaning in Westlake & Cleveland’s West Side
Remove Black Streaks, Moss & Algae Without Damaging Your Shingles.
Those Black Streaks Aren’t Just Dirt
The dark streaks running down your roof aren’t stains from weather or age — they’re a living organism called Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Once it takes hold, it spreads across the entire roof, trapping moisture against the surface and accelerating shingle deterioration.
Moss is even more destructive. It grows between and underneath shingles, lifting them away from the roof deck and creating pathways for water infiltration. In Northeast Ohio’s freeze-thaw climate, that trapped moisture causes real structural damage over time.
The good news: a professional roof cleaning removes all of this growth and restores your roof’s appearance — often making it look decades younger. And it’s done without high pressure, so your shingles stay intact.
Soft Wash Only — Never High Pressure on Your Roof
High-pressure washing will strip the protective granules off asphalt shingles, void manufacturer warranties, and shorten your roof’s lifespan. That’s why PressureWays uses an exclusive soft wash system for every roof cleaning.
Our soft wash method applies a specialized, biodegradable cleaning solution at low pressure. The solution kills algae, moss, mildew, and lichen at the root — not just on the surface. The result is a thorough, lasting clean that won’t damage your shingles, flashing, or gutters.
This is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA) and is the only approach we use on roofing materials.
Our Roof Cleaning Process
Step 1: Ground-Level Inspection
We assess the roof’s condition, identify areas of heavy growth, and note any damage or vulnerabilities. We’ll discuss what to expect before any work begins.
Step 2: Property Protection
Landscaping, outdoor furniture, vehicles, and any items near the roofline are covered or moved. We take extra care to protect plantings from runoff.
Step 3: Soft Wash Application
Our cleaning solution is applied evenly across the entire roof surface using our low-pressure system. The solution dwells on the surface, penetrating and killing organic growth at the root level.
Step 4: Natural Rinse Cycle
For most roof types, the cleaning solution is left to work and rinses naturally with the next rain. For heavily soiled roofs or specific materials, we may perform a gentle low-pressure rinse on site. Either way, you’ll see dramatic results within days.
Roof Types We Clean
- Asphalt shingles (3-tab and architectural)
- Cedar shake and wood shingles
- Metal roofing
- Tile and slate
- Flat and low-slope roofing
- Composite and synthetic materials

Frequently Asked Questions About Roof Cleaning in Westlake, OH
How often should I have my roof cleaned?
In the Westlake area, most roofs benefit from cleaning every 2–3 years. If you notice black streaks or moss patches appearing sooner, it is a good idea to schedule a cleaning before the growth damages your shingles.
Will pressure washing damage my roof shingles?
We never use high-pressure water on roofs. Our soft wash method relies on specially formulated detergents applied at low pressure to kill algae, moss, and lichen without voiding your shingle warranty or damaging flashing.
Can roof cleaning extend the life of my shingles?
Yes. Algae and moss hold moisture against your shingles and can shorten their lifespan. Removing that growth helps your roof dry properly and can add years of useful life to your roofing investment.
Do you clean all types of roofs?
We clean asphalt shingle, tile, metal, and most other common roofing materials. We adjust our approach and cleaning solutions based on the material to ensure a safe, effective clean.
