Central Virginia Power Washing uses the ARMA-recommended soft washing method to clean asphalt shingle roofs without high pressure that could damage protective granules. Low-pressure biodegradable cleaning solutions kill moss, algae, and lichen on contact. Dead organic matter naturally falls away over weeks to months with wind and rain, revealing a cleaner roof while preserving its integrity and lifespan.

Why Soft Washing Is the ARMA-Recommended Method

The Asphalt Roofing Manufacturers Association (ARMA) specifically recommends soft washing over high-pressure methods because it protects the protective granules embedded in shingles. These granules shield your roof from UV damage and weather, and losing them significantly shortens roof lifespan.

High-pressure washing can blast away granules, create water intrusion points, and void manufacturer warranties. Soft washing uses low pressure and biodegradable cleaning solutions to kill organic growth without mechanical damage, preserving your roof's integrity while eliminating algae, moss, and lichen.

Understanding the Natural Falling-Away Process

After our soft wash application kills moss and lichen, these organisms don't disappear immediately. Instead, they fall away naturally over weeks to months as wind and rain loosen the dead material. This gradual process is intentional and protective.

Forcefully removing dead growth can pull up shingle tabs, damage granules, and create vulnerability to leaks. The natural falling-away method preserves your roof structure while achieving thorough cleaning results. Depending on severity, heavier growth may take longer to completely clear.

What Causes Black Streaks and Moss on Roofs

The black streaks commonly seen on roofs are caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Moss and lichen growth is more common on north-facing slopes and shaded areas with moisture retention.

Beyond appearance issues, organic growth retains moisture against your roof surface, accelerating deterioration and potentially leading to wood rot in underlying decking. Regular soft washing eliminates these organisms and protects your roof investment.

What's Included

ARMA-Approved Soft Wash Application: Low-pressure biodegradable cleaning solutions applied safely to kill all moss, algae, and lichen without damaging protective roof granules.

Complete Roof Coverage: Treatment of all roof surfaces including valleys, ridges, and areas with heavy organic growth for thorough and even cleaning.

Professional Assessment: Evaluation of your roof condition and growth severity to determine appropriate treatment and set realistic timeline expectations.

Protection of Landscaping: Pre-rinse and post-rinse of surrounding vegetation and landscaping to ensure biodegradable solutions don't harm plants.

Bottom line: The Asphalt Roofing Manufacturers Association recommends soft washing (low-pressure chemical cleaning) over high-pressure methods to remove algae and moss without damaging protective shingle granules that are essential for roof longevity and UV protection.

Who Is Roof Cleaning Good For?

Good candidates: Roof cleaning is ideal for homeowners with asphalt shingle roofs showing black streaks, moss, or lichen growth, particularly on north-facing or shaded slopes. Best performed as preventive maintenance every 2-3 years to extend roof lifespan and maintain curb appeal.

Who should consult a doctor first: Consult before booking if you have a roof type other than asphalt shingles, existing roof damage or leaks, very old or brittle shingles, or concerns about warranty coverage. A pre-service assessment can determine if soft washing is appropriate for your specific roof condition.

General safety: Soft washing is the safest method recommended by the Asphalt Roofing Manufacturers Association. Biodegradable solutions are used to protect landscaping. The low-pressure approach prevents granule loss, shingle damage, and water intrusion that can occur with high-pressure methods.

Frequently Asked Questions

Our soft wash kills moss and lichen on contact, but we let them fall away naturally with wind and rain rather than forcefully removing them. This ARMA-recommended approach protects your roof granules and structure.

Will soft washing damage my roof shingles?

No. Soft washing is the method recommended by the Asphalt Roofing Manufacturers Association specifically because it uses low pressure and biodegradable solutions that won't damage granules or shorten your roof's lifespan.

What types of roofs can you clean?
