Roof Soft Washing

Roof soft washing is the superior alternative to pressure washing. Your roof quietly protects your home from the elements year-round. It keeps you dry, warm, and safe, but it also takes a beating. Over time, it develops black streaks, green patches, and fuzzy clumps of moss. These stains are more than just ugly. They’re signs of algae, mold, mildew, and lichen actively breaking down your shingles.

If you’ve noticed discoloration or growth on your roof, don’t wait. Soft washing is a safe, effective solution that removes stains and protects your investment. At Superior SoftWash, we specialize in restoring roofs using a gentle, non-damaging process backed by our 5-Year Clean-Roof Guarantee.

The Problem with Roof Stains and Growth

Black streaks that run down asphalt shingles? That’s Gloeocapsa magma—a type of algae that feeds on the limestone in your shingles. It slowly degrades the surface and causes premature aging. Left untreated, it shortens your roof’s lifespan.

Moss and lichen are even worse. They anchor into your shingles and trap moisture. That moisture leads to cracking, curling, and softening of the roofing material. Eventually, this leads to leaks and expensive repairs.

Mold and mildew thrive in shaded or moist areas. These organisms not only damage the roof but can also affect your indoor air quality if they spread beneath the surface.

A dirty roof isn’t just an eyesore, it’s a warning sign. Routine roof soft washing keeps your shingles healthy and your home protected.

Roof Power Washing? Don’t Do It!

Power washing a roof is one of the most damaging things you can do. High-pressure water strips granules off asphalt shingles. These granules are what protect your roof from UV rays and weather. Once they’re gone, the shingles fail faster.

Power washing can also dislodge cedar shingles or force water under them, leading to mold in the attic or beneath the sheathing. Even worse, the intense pressure doesn’t kill the organisms growing on your roof. It just blasts the surface—leaving spores behind to regrow quickly.

Some homeowners have even voided their roof warranty by using a pressure washer. That’s why soft washing is not only recommended but often required by roofing manufacturers.

How Roof Soft Washing Works

Our authentic soft washing system is safe, thorough, and built to last. We use a 12-volt battery-powered agricultural sprayer to apply our Superior Secret Sauce. A biodegradable, water-based cleaning solution that is applied at just 50 psi. That’s about the pressure of a standard garden hose.

This low-pressure application allows the cleaning solution to soak into the shingles. It emulsifies dirt, kills mold, mildew, algae, moss, lichen, and bacteria, and breaks down webs and bug nests. After allowing the solution to work, we rinse the roof gently—no blasting, no blowing, no damage.

Because we’re not just cleaning the surface, but sanitizing it at the root, your roof stays clean three to six times longer than with traditional methods.

Roof Types We Clean: Asphalt and Cedar

Different roofing materials require different approaches. Fortunately, soft washing works on both asphalt and cedar shingles without compromising the structure.

Asphalt Shingles

Asphalt shingles are the most common roofing material in Maryland. They’re durable and cost-effective, but also prone to black streaks and algae growth. Over time, contaminants wear down the protective granules. Power washing removes granules too, speeding up deterioration.

Roof soft washing safely lifts dirt and kills algae at the root. Your roof will look newer and last longer without the risk of damage. Our method restores the color, improves curb appeal, and helps shingles stay strong for years to come.

Cedar Shingles

Cedar roofs offer a natural, rustic look and excellent insulation, but they require proper care. Cedar is especially vulnerable to moss, mold, and mildew. Pressure washing can crack or loosen the wood and force water beneath the surface.

Soft washing gently removes growth and restores the natural beauty of your cedar shingles. It also prevents moisture from getting trapped, helping the wood age evenly and resist decay.

Whether your roof is darkened with algae or overrun by moss, soft washing is the solution that keeps it healthy—without harm.

Long-Term Protection, Backed by a Guarantee

At Superior SoftWash, we stand behind our work. That’s why we offer a 5-Year Clean-Roof Guarantee. When we soft wash your roof, we don’t just clean it—we sanitize and protect it. Most of our clients enjoy a clean roof for four years or longer.

This long-lasting result is possible because our solution kills the organic growth at the source. There’s no surface-level fix here. You get a truly clean, restored roof that holds up season after season.

We also use two-thirds less water than pressure washing, making our method better for the environment and your water bill.

More Than Just Curb Appeal

A clean roof looks great from the street, but the benefits go deeper than aesthetics.

•    Extend Roof Life: Regular soft washing prevents early failure of shingles and underlayment.

•    Avoid Costly Repairs: Eliminating moss and mold protects against rot and leaks.

•    Improve Efficiency: A clean roof reflects heat better, keeping your attic and home cooler.

•    Boost Home Value: First impressions matter, especially if you’re planning to sell.

Protecting your roof is protecting your investment. Soft washing offers a smart, safe way to keep it in top shape without risk.
