Has your Reston roof developed those ugly black streaks and green moss that scream neglected? These aren't just cosmetic problems—they're living organisms actively destroying your shingles. Diamond Power Washers delivers expert soft wash roof cleaning in Reston, VA, using proven no-pressure methods to safely remove growth and revive your roof's appearance. We work with homeowners throughout Reston's top communities, from Brambleton to Ashburn Village, preserving their primary investment and strengthening property attractiveness.
Professional roof cleaning applies eco-friendly solutions at gentle pressure to eliminate black streaks (Gloeocapsa magma algae), moss, and lichen feeding on your shingles. Chemistry does the cleaning while low pressure protects roof integrity.
In our Reston climate, roof organisms aren't merely unsightly HOA issues—they're real damaging agents. They elevate shingles, allow moisture intrusion, and seriously reduce roof longevity, potentially necessitating premature costly replacement.
Diamond Power Washers uses only the ARMA-approved soft washing method. Our certified technicians apply specially formulated solutions at garden-hose pressure, destroying all organic growth at the source. Natural rainfall then rinses away dead organisms over time, producing a pristine, undamaged roof. We never pressure wash roofs—ever.
As an Reston resident, you enjoy a community recognized for attractive homes and diligent property upkeep. Our humid Virginia climate makes landscapes beautiful but also creates optimal conditions for the damaging organisms infesting your roof. The black lines running down your roof aren’t dirt or smoke stains—they’re algae called Gloeocapsa magma. These organisms, along with moss and lichen, are devouring the limestone in your shingles, systematically wrecking your roof.
Diamond Power Washers stands ready as your trusted local resource for professional roof cleaning services in Reston, VA. We have developed a specialized service that is specifically designed to combat this problem safely and effectively. We appreciate that pressure washing roofs is destructive, eliminating protective granules and inflicting lasting damage. Our purpose is to execute proven, careful soft washing that brings back your roof’s beauty while extending its life, defending your primary asset. As a veteran-operated company, we contribute the accuracy, quality standards, and reliability that Reston homeowners need and deserve.
To achieve pristine, protected, and enduring results, Diamond Power Washers uses only soft washing, the sole method approved by ARMA for asphalt shingle cleaning. This is a no-pressure, detergent-based cleaning process that places roof integrity and protection first.
Our process begins with a thorough inspection of your roof and the protection of your property. We thoroughly protect or pre-rinse all vegetation and landscaping around your house. Our skilled technicians then employ dedicated pump equipment to apply our proprietary, environmentally safe solution to your entire roofing surface. This is executed with a gentle water flow, usually at pressure less than your garden hose.
This powerful solution is the key to our process. It’s a specialized mixture of algaecides and surfactants that immediately begins eradicating all organisms at their roots. The solution infiltrates deep into organism colonies, destroying them totally. For homes with thick moss, the moss becomes white signaling it’s killed. We then permit gentle rain to wash away dead material and solution over the coming weeks. This is the most secure, natural completion process, needing no pressure or aggressive rinsing. The result is a roof that becomes cleaner and brighter with each rainfall, fully restoring its original color and appearance.
As a locally owned and operated company, Diamond Power Washers knows Reston, VA from Lake Anne and North Point down to South Lakes and the Wiehle-Reston East corridor.

Through removing damaging organisms consuming your shingles, our cleaning can extend roof life by years. Professional cleaning costs a small fraction of early roof replacement, which can easily run $15,000-$20,000+ in Reston. It's the most cost-effective roof maintenance you can perform.
The dark algae on your roof soaks up solar energy, making your attic and upper levels much hotter. This makes your air conditioner work harder, pushing up your energy expenses. A clean, reflective roof works more efficiently, delivering measurable savings on utility expenses.

Yes. Soft washing is the manufacturer-recommended method because it’s totally non-damaging to roofing materials. We use complete protection procedures for your landscaping, including pre-soaking and covering vegetation, making certain our biodegradable solutions are harmless.
The black algae streaks disappear before we finish the service. The moss and lichen are killed instantly and become white. These dead organisms then rinse away naturally with rain over coming weeks, leaving your roof looking fully restored.
Our professional soft wash roof cleaning process kills 100% of the growth at the root. We’re so sure of our method that we guarantee 3 years with no black streaks. This delivers lasting confidence in your roof’s appearance.
Pressure washing destroys roofs. Period. The force strips away the ceramic granules that protect your shingles from sunlight and weather. Without these granules, your shingles lose protection against UV rays and start breaking down fast—cracking, curling, and failing years before they should. Every roofing manufacturer specifically warns against pressure washing and voids warranties if you do it. High pressure also drives water underneath shingles, creating concealed leaks and rot in your roof deck that can cost thousands to repair. Sure, a pressure-washed roof looks cleaner temporarily, but you’ve just caused expensive damage and cut your roof’s lifespan significantly. Our soft washing method uses specialized solutions that destroy algae, moss, and lichen chemically at their source—no damaging pressure required. This approach works better, lasts longer, and is the only method approved by ARMA and roofing manufacturers.
No, our cleaning solution won’t harm your gutters regardless of material—aluminum, vinyl, copper, or any other type. The solution is engineered to target organic contaminants on roofing without affecting metals, plastics, or finished surfaces. We frequently clean gutters simultaneously with roof treatments and have never caused gutter damage. Before beginning, we evaluate your entire gutter system and apply safeguards to any sensitive components. The same eco-friendly solution that cleans your roof also flows safely through gutters and downspouts. Many customers are pleasantly surprised that their gutters look cleaner after our roof service because the solution gently washes exterior surfaces.
