Rooted Exterior Solutions removes black streaks, algae, lichen and moss from Augusta roofs with a soft wash, never a pressure washer. It's the low-pressure method the Asphalt Roofing Manufacturers Association recommends, and every soft wash roof cleaning we do comes with a 3-year guarantee.
Updated September 2026 by Kenny Monks, owner of Rooted Exterior Solutions.
What Are the Black Streaks on My Roof?
They're algae, usually Gloeocapsa magma, not dirt or mildew. It feeds on the limestone filler in asphalt shingles and spreads fastest where the roof stays damp. Augusta gives it plenty to work with: about 45 inches of rain a year, humid summers and a lot of shade. The streaks usually show up first on the north side and anywhere trees hang over the roof, then spread. Lichen and moss follow on the shadiest spots and hold moisture against the shingles.
Why Not Just Pressure Wash the Roof?
Because it damages shingles. The Asphalt Roofing Manufacturers Association (ARMA) says never to use a pressure washer on an asphalt shingle roof, because it causes granule loss and can lead to early roof failure. Those granules protect the shingle from the sun, and once they're blasted off, they don't come back. High pressure can also void your shingle warranty.
How Does a Soft Wash Roof Cleaning Work?
-
We pre-wet your plants and landscaping so the cleaning solution can't soak in
-
A cleaning solution goes on at low pressure, following the approach ARMA recommends
-
It dwells long enough to kill the algae, lichen and moss at the root
-
We rinse the roof and your plants again at low pressure
-
Gutter faces and fascia can be cleaned in the same visit
Because the growth is killed, not just knocked loose, the roof stays clean far longer than a pressure-washed roof.
How Much Does Roof Cleaning Cost in Augusta?
Soft wash roof cleaning starts at $600. The final price depends on the roof's size, pitch, number of stories and how heavy the algae, lichen and moss are. You'll get an exact written price before we start, the job comes with a 3-year guarantee, and bundling it with a house wash gets a bundle service discount.
Selling, Renting for the Masters, or Just Tired of the Streaks?
A streaked roof makes an otherwise nice Augusta house look older in listing photos, and home buyers notice it. If you rent your home during Masters Week, a clean roof and house are the first thing renters see pulling in. Most owners start prep in January, so book your roof cleaning for February or March before the April rush.
Shade, Big Trees and Older Roofs
In Summerville, Forest Hills, Olde Town and along Walton Way, mature trees keep parts of the roof shaded all day. The shaded side stays damp longer and turns dark first while the sunny side can look fine. We look at the whole roof, including valleys and anywhere branches hang over, before we start.

Frequently Asked Questions
How much does roof cleaning cost in Augusta, GA?
Soft wash roof cleaning starts at $600, depending on the roof's size, pitch, stories and how heavy the growth is. Every job comes with a 3-year guarantee.
Will roof cleaning damage my shingles?
Not with a soft wash. We never use high pressure on a roof. Soft washing is the low-pressure method the Asphalt Roofing Manufacturers Association recommends for removing algae and moss.
How long does a roof cleaning last in Augusta?
Every soft wash roof cleaning we do comes with a 3-year guarantee. How long it stays clean beyond that depends on how much shade and tree cover the roof gets.
Why is only one side of my roof black?
Shade. The side that gets less sun stays damp longer, and that's where algae grows first. It's very common under Augusta's mature trees.
Is roof cleaning safe for my plants?
Yes. We pre-wet plants and landscaping before we start, keep them wet while we work and rinse them again when we finish.
Can you clean the roof and wash the house the same day?
Yes. Many customers bundle the roof, house wash and gutter faces into one visit, and bundled services get a bundle service discount.
