Professional soft wash roof cleaning for Dunwoody and northern DeKalb County
Dunwoody's residential neighborhoods — built primarily from the 1960s through the 1990s across a landscape of rolling hills and mature hardwood forest — produce some of the most algae-affected roofs in northern DeKalb County. The community's signature tall oaks, hickories, and pines have grown to create an almost complete canopy over many streets in neighborhoods like Dunwoody Village, Kingsley, and Georgetown. This canopy, beloved for the shade and character it brings to the community, is also the primary driver of accelerated algae and moss growth on the roofs below.
Rare Earth Ltd provides professional soft wash roof cleaning for Dunwoody homeowners, HOA communities, and property managers. Our process eliminates the black algae streaks, green moss patches, and lichen colonies that diminish your home's curb appeal and degrade your roofing materials. We use low-pressure soft wash application that is safe for all residential roofing types — no high-pressure blasting, no granule displacement, no warranty voiding.
Dunwoody's mature tree canopy is one of its most valued features — the city has invested significantly in tree preservation ordinances and canopy protection programs. But from a roofing perspective, canopy coverage creates a microclimate problem that homeowners cannot escape. Shaded roof sections retain moisture for hours or days after rain events, while unshaded sections dry quickly. Algae, moss, and lichen all thrive in this persistently moist, shaded environment.
The situation is compounded by proximity to Perimeter-area impervious surfaces, which create urban heat island effects that drive condensation patterns on cooler roof surfaces during temperature swings. Dunwoody homeowners frequently report that their roofs appear to re-streak within a few years of a new shingle installation, even without pre-existing contamination — because the algae spores are airborne and ubiquitous, landing on new roofing material and establishing within months when conditions are favorable.
Our biocide-enhanced soft wash treatment kills existing biological growth and leaves a residual that inhibits new colonization for an extended period after treatment. Homes we treat on a two-to-three year cycle maintain a significantly cleaner appearance between treatments than homes receiving one-time cleaning with no residual protection.
Many Dunwoody HOA communities have appearance covenants that require roofs to be maintained free of visible algae or moss growth. Rare Earth Ltd works with HOA management companies to provide community-wide roof cleaning programs at volume pricing. Block scheduling — cleaning multiple homes in a neighborhood on the same day — reduces mobilization costs and allows us to offer community rates that are significantly better than individual home pricing. We provide HOA-ready documentation and service confirmation letters for each property cleaned.
A clean roof paired with dirty siding, algae-stained driveways, and debris-clogged gutters is an incomplete job. We offer bundled exterior cleaning packages that combine roof cleaning, house washing, driveway and sidewalk cleaning, and gutter cleaning for a comprehensive exterior restoration. Bundle pricing is available, and scheduling multiple services in one visit reduces the total time we spend on your property.
