Roof cleaning is one of the highest-value exterior services you can book — and one homeowners have the hardest time pricing, because almost no Central Ohio company publishes numbers. This guide gives you honest, typical market ranges for roof soft washing in the Columbus area so you can budget before you call.
Important: These are typical Greater Columbus market ranges for planning — not a quote. Your actual price depends on the size, pitch, and condition of your roof, access, and whether you bundle it with house or driveway cleaning.
Typical roof cleaning price ranges
- Asphalt shingle roof (single-family home): $300–$700
- House soft washing + roof soft washing together: $600–$1,200
- Larger, steeper, or multi-story roofs: toward the top of the range and up
- Metal, tile, or slate roofs: more than standard asphalt, due to specialized handling and access
Most standard asphalt roofs on an average Columbus-area home land in that $300–$700 window. The rest of this guide explains what moves you within it.
Roof cleaning cost by roof type and height
| Roof | Typical Central Ohio range |
|---|---|
| Single-story asphalt shingle | $300–$500 |
| Two-story asphalt shingle | $400–$700 |
| Steep, complex, metal, or tile | $600–$1,200 |
| House soft wash + roof soft wash, same visit | $600–$1,200 |
Those four rows cover most Columbus-area homes. The three tables below explain what moves a specific roof within its row — the detail almost no company in this market publishes.
Cost factor 1: roof surface area
Roof area is the single biggest driver, and it is not the same number as your home's square footage. A roof always covers more surface than the floor plan beneath it, because it is sloped and because it overhangs the walls. As a rough guide, add about 5–10% to the footprint for a low-slope roof and 20% or more for a steep one, then add the overhangs. We measure it properly during the estimate — this is just to help you place yourself in the table.
| Approximate roof surface area | Where it usually lands |
|---|---|
| Under about 1,500 sq ft | Bottom of the range for that roof's height |
| About 1,500–2,500 sq ft (most common) | Middle of the range |
| About 2,500–3,500 sq ft | Upper end of the range |
| Over about 3,500 sq ft | Above the standard range — priced individually |
Cost factor 2: pitch and access
Pitch is written as rise over run — a "6:12" roof rises 6 inches for every 12 inches of horizontal run. It matters to price because it decides how the crew can work, not because steep shingles are harder to clean.
| Roof pitch | What it means on site | Effect on price |
|---|---|---|
| Low slope, up to about 4:12 | Usually walkable; most of the roof is reachable safely and quickly | Baseline — bottom of its range |
| Medium, about 5:12 to 7:12 | Fall protection required; slower, more deliberate movement across the surface | Moderate increase |
| Steep, 8:12 and above | Not safely walkable; worked from ladders, extended reach, or full rope rigging | Top of the range, or above it on a large roof |
Complex roof lines add cost the same way: dormers, valleys, multiple planes, and steep sections over landscaping all mean more setup and repositioning for the same square footage.
Cost factor 3: roofing material
| Material | How it is cleaned | Relative cost |
|---|---|---|
| Asphalt shingle | Low-pressure soft wash — the method roofing manufacturers and ARMA point to | Baseline (the $300–$700 band above) |
| Metal — standing seam or ribbed | Soft wash with a solution chosen for the coating; never abrasives, which streak the finish permanently | Above asphalt of the same size |
| Cedar shake | Gentle soft wash with a longer, carefully monitored dwell — the most technique-sensitive roof on this list | Above asphalt |
| Tile — clay or concrete | Soft wash only, with no foot traffic on the tiles; access planning is the real cost driver | Toward the top of the range or above it |
| Slate | Soft wash only; brittle and expensive to repair, so every step is deliberate | Highest |
One rule applies to every row: no roof on this list should be cleaned with high pressure. What changes between materials is the chemistry, the dwell, and how the crew reaches the surface — never the amount of force. If you are weighing methods across the rest of your home too, our surface-by-surface soft washing vs pressure washing guide covers every exterior surface.
What drives the price of a roof cleaning
- Roof size (square footage): the biggest single factor — more surface means more solution, dwell time, and rinsing.
- Pitch and number of stories: steep or two- and three-story roofs take more setup, safety equipment, and time than a low single-story ranch.
- Roofing material: asphalt shingle is the baseline; metal, tile, and slate need different chemistry and handling and cost more.
- Severity of growth: heavy black-algae streaking, moss, and lichen (see our guide to Gloeocapsa roof algae) need more product and dwell time than a light preventive clean.
- Access and landscaping: tight lots, delicate plantings to protect, and hard-to-reach slopes add labor.
- Bundling: adding roof to a house soft washing or driveway cleaning visit usually lowers the per-service cost.
Why roof cleaning costs a fraction of a new roof
A roof soft wash is protective maintenance, not just cosmetics. Black algae (Gloeocapsa magma), moss, and lichen hold moisture against your shingles and can shorten roof life. Removing them for a few hundred dollars every few years is a small fraction of the cost of a premature roof replacement — one of the most expensive projects a homeowner faces. Cleaning early, before growth digs in, protects the roof you already paid for.
Why the cleaning method affects both price and value
The cheapest quotes are often high-pressure "power washing," which can strip shingle granules, force water under the shingles, and put your shingle warranty at risk. Low-pressure soft washing — the method roofing manufacturers and ARMA point to — costs a bit more to do correctly, but it kills the algae at the root so the roof doesn't re-streak in a few months, and it keeps your warranty intact. When you compare quotes, compare the method, not just the price.
How to get the best value on roof cleaning
- Ask what pressure and solution they'll use. The right answer is a low-pressure soft wash with roof-safe, diluted chemistry — never a power washer on shingles.
- Ask for proof of insurance. Roof work carries real risk; a professional carries liability coverage and shows it on request.
- Bundle surfaces. Combining roof with house or concrete cleaning in one visit usually beats booking each separately.
- Clean before it's severe. Light, regular cleaning is cheaper than fighting years of caked-on moss and lichen.
