Soft-Wash Roof Cleaning in Melbourne & All of Brevard County, FL
Safe, manufacturer-approved roof cleaning that kills black streaks at the root — no high pressure, no shingle damage, no voided warranties.
Those Black Streaks Are Algae. They’re Eating Your Roof.
The dark streaks you see running down your Melbourne roof aren’t dirt, and they’re not going to wash off in the rain. They’re Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. Brevard County’s humidity, the salt air coming in off the Indian River and Banana River, and the shade from oak trees and pine canopies make this one of the worst environments in Central Florida for roof algae.
Left alone, Gloeocapsa magma does three things. First, it eats the limestone. That pulls the protective granules loose, and once you lose granules, you lose the UV protection that keeps your shingles from drying out and cracking. Second, it traps moisture on the roof surface, which accelerates rot on the plywood decking underneath. Third, it spreads — from the first streak on the north-facing slope, it takes about two years to cover most of the roof.
The fix is soft-wash roof cleaning. Not pressure washing. Pressure washing a shingle roof strips the granules, voids your roof warranty, and forces water up under the shingles into the attic. Every major asphalt shingle manufacturer — GAF, CertainTeed, Owens Corning — specifically recommends soft washing as the only safe cleaning method. We’ve cleaned more than 3,000 Brevard County roofs using it.
Why We Don’t Pressure Wash Roofs (And Why You Shouldn’t Hire Someone Who Does)
| Approach | Soft Wash (what we do) | Pressure Wash (avoid) |
|---|---|---|
| Pressure used | Under 500 PSI (garden hose pressure) | 1,500–3,000 PSI or higher |
| Cleaning agent | Biodegradable algaecide + surfactant | Water alone; brute force |
| Granule loss | None | Significant — shortens roof life |
| Kills algae at root | Yes — algicide penetrates and kills | No — blasts surface, roots regrow fast |
| Manufacturer warranty | Preserves warranty | Voids most shingle warranties |
| Result | Streaks gone in 10–15 minutes, clean for 2–3 years | Looks clean for 6 months, then back worse |
If another roof cleaning company in Brevard is quoting you a “pressure wash” or “high-pressure cleaning” for your shingle roof — ask them what their procedure is if you have a granule loss issue during the job. A professional soft-wash contractor will walk through the answer immediately. A pressure washer will change the subject. The question is how you find the pros.
Our 4-Step Roof Cleaning Process
1. On-Site Assessment
We come to your Melbourne-area property and look at the actual roof. We identify the shingle material (asphalt, architectural, tile), check for loose or damaged shingles, look for problem areas where algae is thickest, and note any landscaping that needs protection. You get a written quote on the spot — no hidden fees, no phone estimates that change mid-job.
2. Landscaping Protection
Before a drop of cleaning solution hits the roof, we wet down and cover the landscaping directly below the eaves — hibiscus, palms, bougainvillea, whatever’s there. For waterfront properties along the Indian River Lagoon or the Banana River, we use extra runoff containment because we know where that water ends up. Our algaecide is biodegradable, but “biodegradable” doesn’t mean “pour it on your prize azaleas.”
3. Soft-Wash Application
Low-pressure application of our cleaning solution — a measured mix of sodium hypochlorite-based algaecide and a surfactant that helps it cling to the roof instead of sliding off. We apply with a 12V pump sprayer from the ground when we can, or from the roof with proper safety harnesses when ridges or valleys need direct treatment. The streaks start dissolving within 10–15 minutes.
4. Rinse & Walkthrough
After dwell time, we do a light rinse if needed (some solutions benefit from sitting until the next rainstorm — we’ll tell you which applies to your property). We post-rinse the landscaping thoroughly to neutralize any residual solution. Final walkthrough with you to confirm you’re happy with the result. If you see anything we missed, we stay until it’s right.
What Does Roof Cleaning Cost in Brevard County?
Every roof is different, so we can’t give you a final number without seeing yours. But here’s an honest range so you know what to budget before you call:
| Home Size | Typical Range | Notes |
|---|---|---|
| Single-story, ~1,500 sq ft roof | $350 – $550 | Most Brevard tract homes |
| Two-story, ~2,500 sq ft roof | $500 – $800 | Standard two-story home |
| Large home, 3,000+ sq ft roof | $700 – $1,100 | Viera estates, larger homes |
| Tile roof (barrel or flat) | Add 15–25% | More labor, different technique |
If a quote comes in significantly below these ranges, ask what’s being skipped. The two most common shortcuts in cheap Brevard roof cleaning are (1) a lighter algaecide mix that won’t kill the roots — streaks come back in months — and (2) no landscaping pre-wet and post-rinse, which kills your plants. Neither of those saves you money long-term.
How Long Will My Roof Stay Clean?
In Brevard County, a properly done soft-wash roof cleaning keeps your roof streak-free for 2 to 3 years. North-facing slopes and heavily shaded roofs may need attention slightly sooner. Homes closer to the water — anywhere along the Indian River Lagoon, the Banana River, or the Atlantic — see slightly faster regrowth because of the salt film that builds up and holds moisture.
A few things that extend roof cleanliness: trimming back tree branches that overhang the roof (blocks sunlight and drops organic debris), making sure gutters are clean and flowing (standing water is where algae colonies start), and keeping the roof clear of pine needles or oak leaves that pile up in valleys. None of that requires us — that’s just good homeowner maintenance.
Roofs We Clean
Asphalt Shingle
The most common roof in Brevard, and the one Gloeocapsa magma loves most. Soft-wash kills streaks at the root without touching granules. Preserves GAF, CertainTeed, and Owens Corning manufacturer warranties.
Concrete Tile
Common on Brevard homes built from the mid-2000s onward. Tile roofs need a slightly different approach — more attention to runoff management because the water channels across the tile rather than absorbing in. We seal cracks we find during cleaning if you want.
Barrel / Clay Tile
Found on higher-end Brevard homes and older Mediterranean-style builds. Clay tile is more porous than concrete tile and holds algae longer. We use a tile-specific dwell time and a lighter initial application to avoid wicking the solution into the porous body.
Metal (Standing Seam)
Less common in Brevard but growing. Metal doesn’t get algae the way shingles do, but it does get a chalk layer from UV oxidation. Soft-wash with a specific metal-safe formulation removes oxidation without dulling the finish.

Frequently Asked Questions
Will roof cleaning damage my shingles?
Not when it’s done correctly. Soft-wash roof cleaning uses pressure under 500 PSI — less than a garden hose — combined with a biodegradable algaecide. Every major asphalt shingle manufacturer (GAF, CertainTeed, Owens Corning) specifically approves the soft-wash method and lists it as a required maintenance step to preserve warranty coverage. What damages shingles is pressure washing — blasting granules off with 2,000+ PSI. That’s never what we do.
How much does roof cleaning cost in Melbourne FL?
Most single-story Brevard homes fall between $350 and $550. Two-story homes run $500 to $800. Larger homes or tile roofs run more. Pricing depends on square footage, roof pitch, algae severity, and whether you have tile vs shingle. We give free on-site estimates — call (321) 432-4340 and we come to your property, look at your actual roof, and give you a written quote.
How long does soft-wash roof cleaning last?
In Brevard County’s humidity, a properly applied soft wash keeps your roof streak-free for 2 to 3 years. Shaded roofs, heavily wooded lots, or coastal homes may need touch-ups slightly sooner. Homes with good sun exposure and clean gutters can go longer. We’ll give you a realistic timeline for your specific property during the estimate.
What are the black streaks on my roof?
Those are colonies of Gloeocapsa magma, a cyanobacteria (sometimes called “blue-green algae”) that lives on asphalt shingles and feeds on the limestone filler in the shingle surface. Brevard County’s combination of heat, humidity, and marine air makes this one of the worst environments in the country for it. Left untreated, Gloeocapsa magma degrades shingles and can shorten roof life by 10–20 years. Soft-wash cleaning kills it at the root.
Is soft washing the same as pressure washing?
No — and the difference matters. Pressure washing uses high pressure (1,500–3,000+ PSI) and water alone. Soft washing uses low pressure (under 500 PSI) combined with a biodegradable cleaning solution that kills algae, mildew, and Gloeocapsa magma at the root. For roofs, soft wash is the only safe method. For concrete and hard surfaces like driveways, pressure washing is appropriate. We use the right method for each surface.
Will the cleaning solution hurt my landscaping?
We take this seriously because we’ve seen what happens when it’s done wrong. Before we apply anything to the roof, we wet down and cover the landscaping directly below the eaves. Our algaecide is biodegradable, but we still pre-wet and post-rinse to make sure nothing stays on your plants. For waterfront properties along the Indian River Lagoon or Banana River, we use additional runoff containment. In thousands of Brevard jobs, we’ve never killed a homeowner’s plants.
Can you clean tile roofs?
Yes — both concrete tile and clay barrel tile. Tile roofs need a slightly different approach than shingles because the water runs across the surface rather than absorbing into it. We use a modified application technique with closer attention to runoff containment. Clay tile specifically is more porous and holds algae deeper, so we use a longer dwell time and a lighter initial application. Tile roof cleaning typically runs 15–25% more than shingle cleaning because of the extra care required.
How quickly can you schedule roof cleaning in Brevard?
Most roof cleaning jobs in Brevard County can be scheduled within 3–7 days. We’re weather-dependent — we don’t apply cleaning solutions when rain is forecast within 4 hours, so heavy rain weeks can push scheduling a few days. If you’re on a tight timeline (selling the home, appraisal coming up, insurance inspection), call (321) 432-4340 and tell us — we’ll do everything we can to fit you in.
