Roof Cleaning Cost in Florida: What Treasure Coast Homeowners Actually Pay

If you've got black streaks running down your roof, you're probably wondering two things: what's causing them, and what it costs to make them go away. Here's the honest breakdown for Treasure Coast homeowners.
What Causes the Black Streaks
Those dark streaks are algae — specifically Gloeocapsa magma. It feeds on the limestone in your shingles and spreads in Florida's humidity. It's not dirt, and it won't rinse off with a garden hose.
What Soft Wash Roof Cleaning Costs
Roof cleaning pricing depends on several factors — every property is different:
- Size of the home and roof
- Roof type (shingle vs. tile)
- Pitch and access (steep roofs take more time and care)
- Level of algae and staining
- Second story or complex layouts
Tile roofs and steep-pitch roofs cost more because they take more time and care. Heavily stained roofs may need a second treatment. The only way to know your number is to have someone look at your roof.
What's Included
A proper soft wash roof cleaning includes:
- Algae and mold treatment that kills growth at the root
- Landscaping and AC protection before we start
- Gutter and downspout rinse-out
- A clean that lasts 2-4 years, not months
Beware of Cheap Bids
If a roof cleaning quote sounds too good to be true, the contractor is probably:
- Using pressure that will damage your shingles
- Skipping the algaecide that prevents regrowth
- Not licensed or insured
Quality roof cleaning is an investment in protecting one of the most expensive parts of your home.
Why Soft Wash Instead of Pressure
Pressure washing a shingle roof strips the granules that protect it — you'll shorten the roof's life. Soft wash uses low pressure and a cleaning solution that kills the algae. The result lasts longer and your roof stays intact.
How Often Should You Clean Your Roof
In most Treasure Coast neighborhoods, every 2-4 years. Shaded homes near water may need it more often.
