If your asphalt roof in Foley, Gulf Shores, or Orange Beach has dark streaks running down the south-facing slope, you are looking at gloeocapsa magma algae feeding on the limestone filler in the shingles. Salt aerosols rolling in past Fort Morgan and humidity off Mobile Bay make Zone 2 a perfect home for it. Pressure washing is the wrong tool. Soft washing is the right one.
This guide walks through how a coastal roof soft wash actually works in Baldwin County, what the visit looks like at homes from Magnolia Springs (36555) out to Ono Island (36561), pricing ranges for single and two-story houses, and the questions to ask before you hire a crew.
Why soft washing wins on coastal asphalt shingles
High-pressure spray on a 12 or 20 year old asphalt roof tears granules off, shortens the life of the shingle, and voids most manufacturer warranties. Soft washing uses a low-pressure fan tip and a biodegradable cleaning solution that kills the algae at the root. The roof gets clean, the shingles stay intact, and the kill prevents regrowth for months.
That matters more here than it does inland. The Wharf at Orange Beach, OWA Theme Park in Foley, and Gulf State Park all sit in the same humid coastal band as your house. Salt aerosols carry miles past Highway 59 and Canal Road. The algae that streaks roofs in Cotton Bayou and Kiva Dunes is the same strain that hits roofs in Glenlakes and Craft Farms, just at slightly different growth rates depending on tree cover.
Quick pricing snapshot. Single-story Foley or Magnolia Springs home (1,500 to 2,200 sq ft footprint): $375 to $675. Two-story Gulf Shores or Orange Beach home with steeper pitch: $600 to $1,100. Multi-roof, multi-story Ono Island home: priced on site. Fixed quote before the rinse starts.

What a Baldwin Preaux Wash roof soft wash actually looks like
A typical roof visit in Zone 2 runs 90 minutes to 3 hours. The team arrives in a labeled truck, walks the property with you, tarps landscaping, pre-wets shrubs along the foundation, and protects any koi pond or AC unit close to the downspouts.
The cleaning solution then gets applied with a soft, low-pressure fan tip across the entire roof surface. It dwells for 8 to 12 minutes. During the dwell, the algae visibly lightens. We then rinse off everything with a controlled fan rinse and walk the property again to confirm no streaks remain on the soffits, gutters, or hardie board.
What we do not do
- We do not walk a roof unless safety access requires it. Most soft washes happen from the ladder or from the lift.
- We do not use a turbo nozzle, surface cleaner, or anything pressurized above the manufacturer-allowed PSI on asphalt or metal roofs.
- We do not leave runoff in your yard or your neighbor in Cotton Bayou or Bear Point. We rinse downstream, into the pavers or the lawn, never toward the bayou.

What to ask before you book a roof wash on the Gulf Coast
If you are calling three crews for quotes on a Foley (36535), Gulf Shores (36542), or Elberta (36530) roof, ask each one the same set of questions:
- What dilution ratio do you use on a 15 year old asphalt shingle?
- Do you pre-wet shrubs and tarp the AC unit on the south side?
- How long does the cleaner dwell before rinse?
- What does the no-streak guarantee cover, and for how long?
- Do you carry general liability insurance, and can you send a current certificate?
A crew that answers all five in plain language is a crew that has actually washed coastal roofs. A crew that hedges or pivots to upselling deck staining is one that is going to bring a pressure washer to a job that should be soft washed.

Best time of year for a coastal roof wash
March through May and September through November are the sweet spots in Baldwin County. The humidity drops just enough that the cleaner dwells properly without flash-drying. Hurricane season (June through November) is fine too, but we time visits around the radar so the rinse holds for at least 48 hours before any front comes through Pensacola Bay.
Snowbirds at The Peninsula and along Perdido Beach Boulevard often schedule a roof wash right before the property goes on the rental market for spring break season. That timing makes sense because every photo for the listing benefits from a clean roof line, and the kill effect carries through the high-traffic summer months.

Frequently Asked Questions
Will soft washing damage my roof shingles in Gulf Shores or Orange Beach?
No. Soft washing uses low pressure and a biodegradable cleaning solution that targets the algae and lichen at the root. The shingles never see the kind of high-pressure spray that strips granules. That is why every major shingle manufacturer recommends soft washing over pressure washing for asphalt roofs.
How much does roof soft washing cost in Foley, AL?
Most single-story Foley and Magnolia Springs homes land in the $375 to $675 range. Two-story homes in Cotton Bayou or Kiva Dunes with steeper pitches and more square footage run $600 to $1,100. Pricing depends on roof size, pitch, access, and how much algae is present. You get a fixed quote before any work starts.
How long does the cleaner stay on coastal roofs?
The cleaning solution dwells for about 8 to 12 minutes, then gets rinsed off with a soft, fan-spray rinse. On a typical Gulf Shores or Orange Beach roof the full visit takes 90 minutes to 3 hours including setup and cleanup.
How often should an Orange Beach or Gulf Shores home soft wash its roof?
Coastal Baldwin County roofs benefit from a soft wash every 18 to 24 months. Salt aerosols, humidity, and bird traffic from Bon Secour National Wildlife Refuge accelerate algae growth, so houses near the water tend toward the shorter end of that window.
Do you protect plants and pets during the roof wash on Highway 59 properties?
Yes. We tarp landscaping, pre-wet shrubs, and rinse decks and pavers when we are done. Pets stay inside for the visit. We have soft washed roofs along Highway 59, Canal Road, and out to Fort Morgan Road for years without a single plant loss.
