How Much Does Roof Cleaning Cost in Florida? Soft Wash vs Pressure Wash for Algae & Black Streaks (2026)

Roof cleaning in Florida typically costs a few hundred to a few thousand dollars, depending on your roof size, pitch, material, and how much algae or staining has built up. Most Florida homes get cleaned with a "soft wash" (low-pressure cleaning solution) rather than high-pressure washing, because high pressure can damage shingles and tiles. The exact price depends on your home, so expect quotes to vary from one pro to the next.

How much does roof cleaning cost in Florida?

Roof cleaning in Florida generally ranges from a few hundred dollars for a small, single-story roof to a few thousand dollars for a large, steep, or heavily stained roof. Price mostly tracks with square footage, roof pitch, roofing material, and the severity of algae or black streaks.

The black streaks you see on many Florida roofs are usually a type of algae that thrives in warm, humid climates. Because Florida stays hot and wet for much of the year, these stains come back faster here than in drier states, which can affect how often you need cleaning and what you pay over time.

Common factors that move the price up or down:

• Roof size and stories — larger and taller roofs take more time and setup.
• Pitch (steepness) — steeper roofs are harder and slower to work on safely.
• Material — asphalt shingle, tile, and metal each require different care.
• Stain severity — heavy algae or moss costs more than a light cleaning.
• Access — landscaping, pools, and tight lots can add time.

For an accurate number, get written quotes from at least a couple of licensed, insured local pros. Avoid anyone who gives a firm price without seeing your roof.

What homeowners should know

Most roofing pros in Florida recommend soft washing over high-pressure washing for algae and black streaks. Soft washing uses a cleaning solution and low pressure to kill algae and lift stains without blasting the surface, while high pressure can crack tiles, strip shingle granules, and void some roofing warranties.

What is the difference between soft wash and pressure wash for a roof?

Soft washing uses a low-pressure spray combined with a cleaning solution to remove algae, mold, and black streaks, while pressure washing relies on high-force water alone. For most Florida roofs, soft washing is the safer choice because high pressure can damage shingles and tiles.

• Soft wash: gentle on the roof, targets the algae that causes stains, and generally keeps roofs looking clean longer.
• Pressure wash: can be effective on some hard surfaces, but on roofs it risks loosening granules, cracking tile, and pushing water where it shouldn't go.

Ask any pro which method they use and why. A trustworthy contractor should be able to explain their approach for your specific roof material.

Why do Florida roofs get black streaks so fast?

Black streaks are typically caused by algae that spreads in warm, humid conditions, and Florida's climate is ideal for it. That means stains can appear and return more quickly than in cooler, drier regions.

Regular cleaning helps manage the look of your roof, but no cleaning permanently prevents algae from coming back. Ask your pro how long their results typically last and what maintenance they suggest.

Is roof cleaning worth it, or should I just replace the roof?

Roof cleaning is usually far less expensive than replacement and is mainly about appearance and keeping algae in check — not fixing structural problems. If your roof has leaks, missing shingles, or storm damage, cleaning won't solve those issues.

If you're unsure whether you need cleaning or repair, have a licensed roofing pro inspect the roof first. A good contractor will tell you honestly if cleaning is the right call.

How do I choose a trustworthy roof cleaning pro in Florida?

Choose a pro who is licensed, insured, and can show verified customer reviews, and who explains their cleaning method before starting. Avoid anyone who pressures you, refuses to put the quote in writing, or won't confirm their insurance.

Look for a contractor who:

• Carries current license and liability insurance.
• Has verified reviews from real local customers.
• Uses soft washing suited to your roof material.
• Provides a clear, written quote after seeing your roof.
