Local roof cleaning You Can Trust
Those black streaks running down your roof aren't dirt — they're actually a type of algae called Gloeocapsa magma. It feeds on the limestone filler in modern asphalt shingles, and it spreads fast across Ohio roofs. Left alone, it holds moisture against the shingles, which leads to moss, lichen, and premature roof failure. A new roof in Marion costs $8,000–$15,000+ — roof cleaning runs a fraction of that.
The wrong way to clean a roof is with high pressure. Pressure washing blasts the granules right off asphalt shingles, voiding your warranty and shortening the roof's life. The right way is soft washing: a low-pressure application of specialized roof cleaning solution that kills the algae, moss, and lichen at the root, then rinses gently. The black streaks disappear and stay gone for years.
At Priceless Powerwashing LLC, we ONLY soft wash roofs — never pressure wash. We use ARMA (Asphalt Roofing Manufacturers Association) recommended methods and solutions, applied with dedicated low-pressure equipment. Locally owned and operated, insured, and careful with your property. We've cleaned roofs all over Marion County, from the historic homes near downtown to newer builds in the subdivisions.
Serving Marion & All Surrounding Areas — from the streets of Marion out to Pleasant Township, Waldo, Caledonia, Prospect, and beyond. Locally owned and operated. A+ BBB rated. Free estimates.
How Our Roof Cleaning Service Works
Free Roof Inspection
We inspect your roof from the ground and eaves (and from a ladder if needed) to assess the type and extent of contamination. We look for moss, lichen, algae streaks, and any shingle damage. We give you a written quote and an honest assessment of what's cleanable.
Protect Property
We pre-wet all landscaping, cover sensitive plants, and divert downspouts to collect runoff. Our cleaning solution is diluted to be safe when properly managed, but we take every precaution with your landscaping — especially in Marion's older neighborhoods with mature plantings.
Apply Roof Cleaner
Using dedicated low-pressure equipment (think the pressure of a garden hose, not a pressure washer), we apply a sodium-hypochlorite-based roof cleaning solution from the bottom up. This kills algae, moss, and lichen at the root — they don't stand a chance.
Dwell Time
We let the solution dwell — usually 15–20 minutes — so it can fully kill the organic growth. Moss and lichen may take a few weeks to fully slough off after the treatment as they dry up and release from the shingles.
Gentle Rinse
We rinse the roof with low-pressure water from the top down. The dead algae and discoloration rinse away, leaving the shingles looking clean and restored without any granule loss.
Landscaping Recovery
We do a final rinse of all landscaping, gutters, and siding to remove any overspray. We're not done until your plants are safe and your property is clean.
What We Clean
- Asphalt shingle roofs (the most common in Marion — and the ones that get those black streaks)
- Fiberglass shingle roofs
- Tile roofs (we adjust method — tile can be fragile)
- Metal roofs (we use a different solution and even lower pressure)
- Flat and low-slope roofs on additions and porches
- Roof flashing and valleys (where moss loves to grow)
- Roof-mounted AC units and vents (around them, carefully)
- Gutters and downspouts as part of a full roof cleaning
Why It Matters
Extends Roof Life
Algae, moss, and lichen hold moisture against your shingles, causing premature aging and failure. A clean roof can last 5–10 years longer than a neglected one. That's thousands of dollars in deferred replacement costs.
Restores Curb Appeal
Black-streaked roofs make a whole house look old and neglected. A clean roof instantly brightens the entire exterior — it's one of the most impactful visual improvements you can make.
A Fraction of Replacement Cost
A new asphalt shingle roof in Marion runs $8,000–$15,000+. Roof soft washing runs $400–$900 for most homes. That's a 10–20x return on investment if it extends your roof's life even a few years.
Won't Void Warranty
High-pressure washing voids most shingle warranties because it strips the granules. Soft washing is the method recommended by ARMA (Asphalt Roofing Manufacturers Association) and won't affect your warranty — we follow their guidelines to the letter.
Roof Cleaning starting at $400
Most single-story Marion homes with asphalt shingles run $400–$700 for a full roof soft wash. Two-story homes and steep-pitch roofs are at the higher end. Heavy moss or lichen may require a second treatment. We give firm written quotes before starting — no surprises.
All pricing is subject to change based on property size, condition, and location. We use GPS mapping and Google Earth to measure your cleaning area for an accurate, fair quote.
Why Trust Us With Your roof cleaning
We're not just another pressure washing company. Here's what makes us different for this specific service.

We Inspect While We Clean
Before we start, we inspect your roof from the ground and eaves for damage, missing shingles, or areas of concern. If we spot anything, we'll tell you — and we won't clean a roof that needs repair first.
Results That Last Years
Our soft wash kills algae at the root. The black streaks disappear and stay gone for 2-4 years, depending on your roof's exposure and surrounding trees. One treatment keeps your roof looking new.
Common Roof Cleaning Questions
Is roof cleaning safe for my shingles?
Yes — soft washing is the safe method. We use low pressure (garden-hose level) and a specialized cleaning solution that kills algae, moss, and lichen at the root. High-pressure washing is what damages shingles — we never do that.
Will it void my roof warranty?
No. Soft washing is the method recommended by ARMA (Asphalt Roofing Manufacturers Association). High-pressure washing voids warranties because it strips granules — soft washing does not.
How long do the results last?
Typically 2-4 years, depending on your roof's exposure to sun, shade, and trees. The algae is killed at the root, so it takes a long time to return. We can set up a recurring treatment every 3-4 years to keep your roof looking new permanently.
Will the cleaning solution hurt my landscaping?
We take extensive precautions: pre-wetting all plants, diverting downspout runoff, and doing a thorough final rinse. Our solution is diluted to be safe when properly managed. We've never lost a plant on a roof cleaning job.
