If you live in the Mall of Georgia corridor or anywhere along the 30519 zip code in Buford, you've probably noticed those dark, blotchy streaks running down your neighbors' rooflines, or maybe your own. A lot of homeowners assume it's dirt or tree stain from all the pines and hardwoods that shade this part of Gwinnett County. It's actually a cyanobacterium called Gloeocapsa magma, and it feeds on the limestone filler in your asphalt shingles. Left alone, it invites moss and lichen, and the damage compounds fast in our humid Georgia summers.
Riverview Property Maintenance does roof soft washing for homeowners all across Buford, from the newer subdivisions tucked behind the Mall of Georgia on the 30519 side to the established neighborhoods in 30518 closer to Lake Lanier. We use a low-pressure application with a professional-grade, biodegradable algaecide that kills the organism at the root rather than just blasting it off the surface. High-pressure washing on shingles knocks off granules and voids most manufacturer warranties. Soft washing is the method roofing manufacturers and the ARMA actually recommend.
Why Buford Roofs Are Especially Prone to Algae and Black Streaks
Buford sits in a humidity belt that makes algae growth almost inevitable on any north-facing or shaded roof surface. The tree canopy around neighborhoods near Ivy Creek and the corridors running toward Sugar Hill holds moisture on shingles well past midday. Pine pollen season, roughly March through May, deposits a thick film on every surface, and that organic layer gives Gloeocapsa magma exactly the foothold it needs. By the time most homeowners notice the streaks, the algae colony has been growing for a year or more.
On top of that, Georgia red clay dust kicked up from construction around the 30519 growth corridors settles on rooftops and mixes with moisture, creating an additional food source. If your home sits under oaks or sweet gums, the leaf debris in your valleys accelerates the problem even further. We see this pattern constantly on homes in the neighborhoods near the Mall of Georgia and along Friendship Road.
What Roof Soft Washing Looks Like From Start to Finish
When Riverview pulls up to your Buford home, the process is low-drama and pretty quick for most standard residential roofs. Here's what we do:
- Pre-rinse and protect all landscaping, downspouts, and any painted surfaces near the roofline
- Apply our professional algaecide mix at low pressure, no more than what a garden hose produces
- Allow dwell time so the solution penetrates and kills algae, moss spores, and lichen at the root
- Rinse thoroughly from the ridge down, following natural water flow to protect granules
- Inspect valleys, flashing, and gutters before we wrap up
- Walk the job with you so you can see the difference before we leave your driveway
Most Buford homes in the 30518 and 30519 zip codes take two to three hours depending on pitch, square footage, and how heavy the algae growth is. We work around your schedule and our crews are punctual, we know your time matters.
Neighborhoods and Areas We Serve in Buford, GA
We are on rooftops all over Buford and the surrounding communities on a regular basis. Some of the neighborhoods where we do the most roof soft washing work include areas near the Mall of Georgia along Buford Drive and Highway 20, subdivisions off Gravel Springs Road in 30519, established homes closer to Downtown Buford in 30518, and communities near the Lanier Islands corridor where lake humidity accelerates algae growth significantly. We also regularly service homes in neighboring Sugar Hill, Flowery Branch, and Braselton when those calls come in.
How Often Should Buford Homeowners Schedule Roof Soft Washing?
For most Gwinnett County homes with significant tree shade and north-facing exposure, every two to three years is a reasonable maintenance interval. Homes with full sun exposure and less canopy cover can often go three to four years between treatments. If you are getting ready to sell, a clean roof makes a serious impression from the curb and can influence how an appraiser perceives overall maintenance. If you just had a home inspection flag algae or moss growth, soft washing is the fastest and most affordable fix.
We often bundle roof soft washing with house soft washing or gutter cleaning so you get the whole exterior dialed in at once. Many Buford homeowners find it makes sense to schedule before the intense heat of July and August sets in, or again in the fall after pine pollen and oak debris season winds down.

Frequently Asked Questions, Roof Soft Washing in Buford, GA
Frequently Asked Questions
Is soft washing safe for all types of shingles common in Buford homes?
Yes. Soft washing is safe for standard 3-tab and architectural asphalt shingles, which are the most common types on Buford homes built since the 1990s. The low pressure we use, roughly equivalent to a standard garden hose, does not dislodge granules or stress the shingle mat. It is the cleaning method recommended by most shingle manufacturers and the Asphalt Roofing Manufacturers Association.
Will the cleaning solution harm my landscaping or grass?
We pre-wet all landscaping before we apply the algaecide mix and rinse thoroughly afterward. The biodegradable solution we use is diluted to a concentration that is effective on algae and moss but not harmful to established plants when properly rinsed. We have treated hundreds of Gwinnett County homes without landscape damage issues.
How long does it take for the black streaks to disappear after treatment?
You will see significant improvement immediately after the rinse, but the full result becomes clear within two to four weeks as the dead algae naturally weather away with rain and sun. Some stubborn lichen may take a full rain cycle or two to completely release from the shingle surface.
Do I need to be home during the roof soft washing appointment?
You do not need to be present for the work, but we do ask that someone be available at the start so we can confirm access to your water supply and go over any specific concerns. After that, most customers head to work and come home to a clean roof. We will call or text when the job is done.
How much does roof soft washing cost for a typical Buford home?
Pricing depends on the square footage of the roof, the pitch, and the severity of the algae growth. Most single-family homes in the 30518 and 30519 zip codes fall within a range that is significantly less than even a partial shingle replacement, and clean shingles last longer. Call us at (470) 968-5156 for a free, no-obligation quote specific to your home.
Can I bundle roof soft washing with other exterior cleaning services?
Absolutely, and most customers save money by bundling. We regularly combine roof soft washing with house soft washing, gutter cleaning, and driveway or patio pressure washing on the same visit. It is more efficient for our crew and more convenient for you. Mention the services you want when you call and we will put together a combined quote.
