The professional staff at Nashville Cleaning Company™ offers safe and effective roof washing services for residential and commercial customers throughout Middle Tennessee.

Your roof is one of the most important and expensive components of your property, and proper maintenance can help extend its life while improving your home’s curb appeal.

Over time, roofs can develop black streaks, algae, mold, mildew, moss, and other organic growth that not only affects appearance but can also contribute to premature deterioration. As algae and other contaminants remain on the roof, they can retain moisture and gradually damage roofing materials, potentially shortening the lifespan of the roof.

Regular roof maintenance and cleaning can help prevent these issues and may also help homeowners avoid complications during insurance inspections or claim reviews. While homeowners insurance is designed to cover sudden and accidental damage, many policies exclude damage resulting from neglect, deferred maintenance, or normal wear and tear. Keeping your roof clean and properly maintained is an important part of protecting both your investment and the long-term condition of your home.

Unlike traditional pressure washing, our roof washing process uses a specialized cleaning solution and a soft washing technique that relies on zero pressure at the roof surface. This is the method recommended by asphalt shingle manufacturers, because it eliminates algae, mold, and mildew without the risk of damage that high-pressure cleaning can cause. The cleaning solution does the work — not water pressure. Roof cleaning typically requires a stronger solution than a standard house wash in order to break down the stubborn algae, bacteria, mold, and organic growth commonly found on asphalt shingle roofs, all while keeping the process safe and pressure-free.

Soft Washing for Your Entire Exterior

While roof washing is one of the most common applications of soft washing, the same gentle process is used on many other exterior surfaces around your home or business. Soft washing combines specialized cleaning solutions with low-pressure water application to safely clean surfaces that could otherwise be damaged by excessive pressure — including house siding, soffits, fascia, gutters, painted surfaces, vinyl, stucco, and other exterior building materials. The solution strength is adjusted depending on the surface: roofs generally require a more concentrated mix to eliminate algae and organic growth, while house washing and other applications use lower concentrations designed for those specific surfaces. The result is a deeper clean that removes dirt, algae, mold, mildew, and organic growth at the source, helping surfaces stay cleaner longer.

At Nashville Exterior Cleaning Company™, protecting your property is just as important as cleaning it. Before every roof washing project, we thoroughly wet all surrounding landscaping, vegetation, and areas where gutter downspouts discharge. Throughout the cleaning process, we continuously rinse and water these areas while applying the cleaning solution, and we perform a final thorough rinse once each roof section is complete. Consistent watering before, during, and after cleaning is a critical part of our procedure and helps protect your landscaping and surrounding surfaces.

Our experienced team has advanced training in both roof washing and soft washing techniques. We know how to properly mix and apply cleaning solutions, safely access roof surfaces, and select the right method for each project — whether your roof needs a complete cleaning, a partial roof wash to address specific stained areas, or your home needs a full soft wash.

A professional roof wash not only improves the appearance of your property but also removes the organic growth that can shorten the lifespan of your roofing materials. If your roof is showing black streaks, algae growth, moss, or other signs of buildup, let the professionals at Nashville Cleaning Company™ handle the job safely and effectively. We’re available six days a week, year-round, and would be happy to provide a free estimate for your roof washing or soft washing project.
