Drive through any neighborhood in Robertsdale or Loxley and you will notice the same thing on a good portion of the roofs: dark gray or black streaks running from the ridge down toward the gutters. Most homeowners chalk it up to age or weather staining. It is not. That discoloration is a cyanobacterium called Gloeocapsa magma, and it feeds on the limestone filler in your asphalt shingles. Left alone, it shortens the life of a 25-year roof by a decade or more. Baldwin Preaux Wash handles roof soft washing across north Baldwin County, including Robertsdale (36567), Loxley (36551), and the surrounding communities along US-90 and Baldwin County Road 64.
Why Soft Washing, Not Pressure Washing, Is the Right Tool for Shingles
A pressure washer running at 2,000 to 3,500 PSI will absolutely strip algae off your shingles. It will also blast off the granules that protect the mat underneath, void most manufacturer warranties, and potentially force water up under the shingle line. Soft washing uses low-pressure delivery, typically under 100 PSI at the surface, combined with a professional-grade surfactant and sodium hypochlorite solution. The chemistry does the killing. The rinse water does the removing. Your shingles stay intact, and the algae is dead at the root rather than just scraped off the surface.
What Makes Robertsdale and Loxley Roofs Especially Vulnerable
Both Robertsdale and Loxley sit in the middle of north Baldwin County, surrounded by mature pine and oak canopy. That tree cover keeps rooflines shaded for much of the day, which means moisture lingers on the shingles longer than it would on a Gulf-front property with full sun exposure. Combine that with south Alabama's summer humidity, afternoon thunderstorms rolling off Mobile Bay, and warm overnight temperatures, and you have nearly perfect growing conditions for algae and moss from about April through October. We see it on homes in the Loxley Heights area off CR-64 just as often as on older ranch-style houses near downtown Robertsdale. The zip code and the roof age do not matter as much as the shade and the humidity.
Signs Your Roof Is Ready for a Soft Wash
- Black or dark gray streaks running vertically down the shingle field
- Green moss patches forming along the north-facing or shaded sections of the roof
- A general dull, dirty appearance that does not match the age of the roof
- Visible granule loss in the gutters combined with surface discoloration
- HOA or insurance notice citing roof appearance or biological growth
- Neighbors on the same street with the same problem, which is common when tree canopy is shared

How Baldwin Preaux Wash Handles a North Baldwin Roof Soft Wash
When we show up to a home in Robertsdale or Loxley, the first thing we do is walk the property and identify anything that needs to be protected before we apply solution: landscaping beds, AC units, painted wood trim, and gutters that drain into a decorative pond or rain barrel. We wet down surrounding plants as a precaution. We then apply our SH-based mix from the ground or from the eaves, working upward against the direction of water flow so the solution dwells on the surface rather than sheeting off immediately. After the appropriate dwell time, we rinse with low pressure, starting at the ridge and working toward the gutters. The entire process on a standard 1,800 to 2,400 square foot home typically runs two to three hours. Results are visible the same day, and the biological growth continues to die off and rinse away with rain over the following two to three weeks.
Areas We Cover in North Baldwin County
Our north Baldwin service area runs from the Robertsdale city limits (36567) west along US-90 into Loxley (36551), and we also make regular runs up toward Bay Minette and down the Eastern Shore corridor to Daphne and Spanish Fort when jobs are scheduled in those areas the same day. If you are on a rural property off one of the county roads between Robertsdale and Loxley, give us a call at (251) 978-5503. We have serviced homes on narrow gravel drives and long wooded lots throughout this part of Baldwin County and we come prepared with enough hose and tank capacity to reach the peak without needing a hookup from your outdoor spigot.
Roof Soft Washing and Your Insurance or HOA
It comes up more than you would expect. Several homeowners in north Baldwin County have contacted us after receiving a letter from their insurance carrier stating that roof-related claims could be denied or premiums increased if biological growth is documented on the roof surface. Some community covenants in newer Robertsdale subdivisions have similar language about exterior maintenance. A properly documented soft wash with before-and-after photos is often enough to satisfy those requirements. We can provide a simple service summary with photos if you need one for your records.
Insurance letters, HOA notices, or just tired of looking at those streaks. We can help with all three. Call (251) 978-5503.
How Often Should You Soft Wash a Roof in This Area
In a high-humidity, high-shade environment like Robertsdale or Loxley, most homeowners see algae begin to return within three to five years after a proper soft wash. That timeline shortens if you have significant tree overhang that keeps the roof wet or if you are on a lot with poor airflow. Some customers in particularly shaded areas schedule a treatment every two to three years as preventive maintenance. That is a much cheaper call than a premature roof replacement, and it keeps the property looking sharp year-round.
What a Roof Soft Wash Costs in Baldwin County
Pricing depends on square footage, roof pitch, and accessibility. A straightforward single-story home in Robertsdale or Loxley typically runs less than most homeowners expect when they hear the word roof cleaning. We give free on-site or photo-based quotes. Call us at (251) 978-5503 or send a few pictures of the roof and we can usually give you a number the same day.

Frequently Asked Questions
Will soft washing damage my asphalt shingles?
No. Soft washing uses low pressure, well under 100 PSI at the roof surface, so there is no force that can dislodge granules or crack shingles. The cleaning solution is diluted to a concentration that kills algae and moss without degrading the shingle mat or voiding manufacturer warranties. Pressure washing at high PSI is the method that causes damage, which is why we do not use it on rooflines.
How long does it take for the black streaks to disappear after treatment?
You will see a significant improvement the same day the work is done. The dead algae continue to break down and rinse off with rain over the following two to three weeks. By the end of the first good rain cycle, most roofs in Robertsdale and Loxley look like the streaks were never there.
Is the cleaning solution safe for my landscaping?
We take precautions before every job. Surrounding plants, flower beds, and lawn areas are pre-wetted before application and rinsed again after the process. At the dilution rates we use for roof soft washing, well-watered plants handle the process without issue. If you have particularly sensitive plantings directly below the roofline, let us know ahead of time and we will take extra steps.
Do you need access to my water supply to do the job?
For most jobs in Robertsdale and Loxley we are self-contained with our own tank water. We will let you know at the time of the quote if the scope of the job requires a supplemental connection. Many rural properties on county roads in north Baldwin County do not have a convenient outdoor spigot and we plan accordingly.
Can you soft wash a metal roof or a tile roof?
Yes. The chemistry and technique adjust slightly depending on the roofing material. Metal roofs require a gentler solution concentration to prevent any surface oxidation. Tile roofs need careful attention to avoid dislodging the tile edges during rinse. We have worked with all common roofing materials found in north Baldwin County and will confirm the right approach during the estimate.
Do you serve areas outside Robertsdale and Loxley in north Baldwin County?
Yes. We work throughout Baldwin County, including Bay Minette, Stockton, and the Eastern Shore communities of Daphne, Fairhope, and Spanish Fort. We also serve Gulf Shores, Orange Beach, Foley, and Mobile. Call (251) 978-5503 and we will let you know if your address falls in our current service area.
