Are ugly black streaks and green moss patches on your roof diminishing the beauty of your Fairfax home? This isn't just discoloration—it's living algae and moss that's damaging your roof right now. Diamond Power Washers brings expert roof cleaning to Fairfax, VA homes, using damage-free soft washing to remove growth and restore authentic roof color. We work with homeowners throughout Fairfax's top communities, from Brambleton to Ashburn Village, preserving their primary investment and strengthening property attractiveness.
Professional roof cleaning uses soft washing—not high pressure—to apply specialized, biodegradable cleaning solutions that kill and remove black streaks (Gloeocapsa magma algae), moss, and lichen growing on and eating your shingles. The chemicals do the work, not pressure.
Fairfax's persistent humidity makes roof organisms more than cosmetic HOA problems—they're genuine destructive forces. They lift shingles, permit water penetration, and dramatically reduce roof life, potentially forcing you into a costly premature replacement.
Diamond Power Washers employs the soft washing process specified by roofing manufacturers. Our skilled technicians apply eco-friendly solutions at low pressure, killing all growth completely at the root. Natural rain then rinses dead material away gradually, leaving roofs clean and totally unharmed. Pressure washing never happens.
Living in Fairfax means you’re part of a community famous for gorgeous homes and careful property maintenance. Yet the humid Virginia climate that makes our area green also creates ideal conditions for the ugly, damaging organisms now growing on your roof. The black lines running down your roof aren’t dirt or smoke stains—they’re algae called Gloeocapsa magma. This algae, along with moss and lichen, is actively feeding on the limestone filler in your asphalt shingles, slowly but surely destroying your roof from the outside in.
Diamond Power Washers functions as your go-to local provider for professional roof cleaning solutions across Fairfax, VA. We’ve created targeted services that directly address this issue through safe, effective methods. We know that pressure washing roofs is catastrophic, stripping protective granules and causing permanent damage. Our mission is to provide a scientifically proven, gentle, and highly effective soft washing service that not only restores your roof’s beauty but also extends its life, protecting your most valuable asset. As a veteran-operated company, we contribute the accuracy, quality standards, and reliability that Fairfax homeowners need and deserve.
To deliver a perfectly clean, safe, and long-lasting result, Diamond Power Washers exclusively utilizes the soft washing method, the only process approved by the Asphalt Roofing Manufacturers Association (ARMA) for cleaning asphalt shingles. This is a gentle-pressure, solution-based cleaning approach that prioritizes roof protection and integrity above everything.
We start with a complete roof evaluation and comprehensive property protection measures. We meticulously protect or pre-rinse all vegetation and landscaping around your property. Our trained technicians then use a specialized pump system to apply our proprietary, biodegradable roof cleaning solution to the entire surface of your roof. This occurs with a controlled water flow, often at pressure softer than your garden hose produces.
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 permeates deeply into biological colonies, eliminating them entirely. For roofs with significant moss, the moss turns white showing it’s dead. We then allow a gentle rain to rinse the dead organic matter and the cleaning solution from your roof over the following 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.

Yes. Soft washing is the only method recommended by roofing manufacturers because it is 100% non-damaging to your shingles. We apply extensive safeguards for your landscaping, including pre-rinsing and covering plants, ensuring our environmentally safe solutions don’t cause damage.
The dark staining vanishes before we leave your property. The moss and lichen will be dead and will turn white. These dead organisms are then gently rinsed away by the rain over the next few weeks, leaving your roof looking completely clean and restored.
Our expert soft washing destroys all organisms completely at their source. We’re so sure of our method that we guarantee 3 years with no black streaks. This gives you long-term assurance about your roof.
Don’t pressure wash your roof—it’s one of the most destructive things you can do. High-pressure water violently rips away the protective ceramic granules that shield your shingles from the sun. These granules are crucial for roof longevity—without them, shingles become vulnerable to UV damage, turn brittle fast, and fail prematurely. Roofing manufacturers universally prohibit pressure washing because it destroys roofs and voids all warranties. You’ll also blast water underneath the shingles, forcing moisture into the roof deck where it causes rot, mold growth, and hidden leaks that become expensive problems later. A pressure-washed roof may look better for a few weeks, but you’ve just damaged it severely and shortened its life by years. Soft washing uses chemistry, not pressure, to kill organisms at the root—delivering superior, lasting results without any damage. That’s why the Asphalt Roofing Manufacturers Association only approves soft washing for asphalt shingles.
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.
