Low-pressure exterior cleaning for Roswell homes and businesses in North Fulton County
Roswell is one of North Fulton County's most desirable communities, and the homes here reflect that — traditional craftsman colonials along the Historic District, sprawling brick estates in the Willow Springs and Horseshoe Bend corridors, and newer construction subdivisions stretching north toward Crabapple Road. What all of these properties share is a common enemy: the persistent organic growth that Georgia's humid subtropical climate produces year-round. Soft washing is the proven, surface-safe method for eliminating that growth without damaging the surfaces beneath it.
Rare Earth Ltd provides professional soft washing services throughout Roswell and the surrounding North Fulton area. We use low-pressure delivery systems operating under 500 PSI, paired with biodegradable cleaning solutions formulated specifically for exterior soft washing. The chemistry does the work — killing algae, mold, mildew, bacteria, and lichen at the cellular level — while gentle water pressure carries the dead organic material away. The result is a thorough clean that lasts two to five times longer than pressure washing alone.
Roswell sits in the upper Chattahoochee River corridor, and the tree canopy here is exceptional. Mature hardwoods, established pines, and ornamental plantings shade rooftops and siding on most residential properties in the city. That shade is beautiful and valuable — it reduces cooling costs significantly during Atlanta's long summers — but it also creates the damp, low-light conditions where algae and mold thrive.
The characteristic black streaking that appears on asphalt shingles across Roswell is caused by Gloeocapsa magma, a cyanobacteria that feeds on the calcium carbonate filler in roofing shingles. It spreads in spore form carried by wind and rain, and once it establishes itself, it retains moisture on the roof surface, accelerating shingle degradation. Left untreated for several years, a bacterial colony that started as cosmetic discoloration causes measurable granule loss and shortens roof lifespan. Soft washing eliminates the bacteria entirely rather than simply redistributing it.
Vinyl and Hardie board siding on Roswell homes develops green algae streaking that runs from roof overhangs downward, particularly on north-facing and shaded elevations. Stucco finishes common on Mediterranean and Tuscan-style homes in the Sentinel Ferry and Country Club of Roswell areas absorb moisture and develop mold colonies that standard pressure washing pushes deeper into the substrate. Soft washing treats stucco without the surface erosion that pressure washing causes.
Soft washing is a two-stage cleaning process. In the first stage, a low-pressure application system delivers a biodegradable cleaning solution to the target surface at pressures typically between 40 and 200 PSI — comparable to a garden hose. The solution contains surfactants that penetrate organic growth and sanitizers that rupture cell walls, killing organisms rather than just dislodging them. Dwell time on the surface allows the chemistry to work completely.
In the second stage, a low-pressure rinse removes the solution along with all dead organic material, dirt, pollen, and environmental staining. The difference from pressure washing is fundamental: soft washing relies on chemistry rather than mechanical force to clean. High-pressure washing at 2,500 to 4,000 PSI can remove surface staining but leaves living organisms behind and frequently damages the substrate — lifting shingle granules, eroding mortar joints, cracking stucco, and forcing water behind siding where it promotes structural mold growth.

Every soft washing job in Roswell begins with a walkthrough assessment. We identify the types of growth present, evaluate surface conditions, note any areas of existing damage, and document landscaping that needs extra protection. We then mix our cleaning solutions at appropriate concentrations for the specific contaminants and surface types on your property.
Before applying any solution, we pre-soak all landscaping, grass, and garden areas at the drip line. Solution is applied systematically from the top of the structure downward, beginning at ridgeline and working to the foundation. After full dwell time, we rinse thoroughly with low-pressure water, neutralizing and diluting all cleaning solution. We walk the property with you before leaving to confirm complete satisfaction.
