Roof Cleaning Cost Estimator in Miami, Florida

Cleaning your roof isn’t just about curb appeal, it’s about protecting your investment, prolonging the life of your roofing system, and preventing hidden damage from algae, moss or debris. At Kleanway Cleaning Services, we’ve helped hundreds of homeowners in the Miami-area understand what factors drive cost and how to budget accordingly. In this guide we’ll break down the typical cost ranges you’ll see locally, what affects those costs, how our estimating process works, and smart tips to get the best value.

What Is the Average Cost of Roof Cleaning in Miami?

In the U.S., roof-cleaning typically runs $0.20 to $0.70 per square foot, meaning a 1,500 sq ft roof would cost between about $300 and $1,050.
 However, in South Florida (where steep pitches, two-story homes, high humidity, and tropical storms can all add complexity), you should expect the cost to sit toward the upper end of that range or even slightly higher depending on condition, roof type, and accessibility.

Typical ballpark for the Miami area:

  • Small single-story home (1,000 sq ft roof) → $400-$900
  • Medium home (1,500 sq ft) → $700-$1,300
  • Large or multi-story (2,000 sq ft +) → $1,200+

(These are example estimates, your actual quote will consider the factors below.)

Cost Breakdown by Size, Cleaning Method, Roof Type, Stories & Labor

Roof Size

The larger the surface area to clean, the higher the cost. Most professionals charge by the square-foot of roof area (which includes overhangs and takes slope into account). Public data:

  • 1,000 sq ft → $50–$750
  • 1,500 sq ft → $75–$1,125
  • 2,000 sq ft → $100–$1,500

Keep in mind, Florida homes often have “usable roof area” larger than footprint because of slopes and eaves.

Cleaning Method

Different methods carry different costs:

  • Blower cleaning (removing loose debris) $0.05-$0.10/sq ft
  • Chemical wash (anti-algae/moss agents) $0.20-$0.30/sq ft
  • High-pressure wash $0.20-$0.60/sq ft — but caution: high pressure may damage some roof materials.
  • Low-pressure wash $0.30-$0.70/sq ft
  • Soft‐wash (lowest pressure + detergents + manual) $0.30-$0.75/sq ft.

We typically favour soft-wash for asphalt shingle and tile roofs because it’s safest in humid/tropical climates and reduces risk of damage or voiding warranties.

Roof Type / Material

Roofing materials affect both method and cost. Example ranges:

  • Asphalt, clay, concrete tiles: soft-wash $0.30-$0.75/sq ft.
  • Metal panels: high-pressure may be acceptable $0.20-$0.60/sq ft.
  • Rubber or tar-&-gravel: chemical wash $0.20-$0.30/sq ft.
  • Also: steep roofs, complex shapes, lots of valleys and features increase cost (extra safety, more labor). For example: adding $0.10/sq ft or more for each story above the first.

Number of Stories / Accessibility

If you have a two- or three-story home, or your roof is hard to access (lots of trees, steep pitch, multiple levels), expect to pay more – often $0.10-$0.15/sq ft higher or more.

Labor & Other Cost Drivers

Labor makes up the bulk of the cost: equipment, crew, insurance, etc. Hourly rates for crews may range widely (some sources show $17-$36/hr) depending on region.
 Other drivers: travel time, equipment setup, safety harnesses, disposal of waste, clean-up of debris etc.

Additional Service Costs & Considerations

Beyond the core roof cleaning, many homeowners opt for extras. At Klean Way we can bundle some of these to increase value:

Service

Typical Range

Gutter cleaning

$0.70-$1.30 per linear foot

Moss removal (if heavy)

$0.20-$0.70 per sq ft

Moss prevention treatment

$150-$250 flat

Stain removal (after cleaning)

$50-$100

Stain-blocking sealant

$20-$30 per gallon (covers ~300 sq ft)

Zinc-oxide treatment for algae/moss prevention

$0.05-$0.15 per sq ft

Solar panel cleaning

$150-$350

Note for Florida homes: the combination of humidity, shading from palm trees, frequent rain, and potential hurricane debris means moss/algae/mildew prevention treatments may be more worthwhile and thus add cost but deliver real value in extending roof life.

Signs You Need Roof Cleaning

Here are the signs that your roof needs attention:

  • Black streaks or dark stains on the roof surface 
  • Visible algae, moss, or lichen growth (especially in shaded areas) 
  • Accumulated damp leaves/debris, especially around valleys/flashing 
  • Bird droppings or nesting debris that can trap moisture 
  • Lifted/shifting shingles, or signs of granule loss (indicating moisture retention)

Prompt cleaning when you spot these signs can save you from more costly repairs or full roof replacement down the road.
