Frequently Asked Questions

Is roof washing safe?

Yes. When performed correctly by trained professionals, roof washing is a safe and effective way to remove algae, bacteria, and organic growth from your roof. At Sunshine State Power Wash, we use a controlled low-pressure soft wash system designed to clean your roof without the damaging effects of high pressure.

How much does roof cleaning cost?

Roof cleaning costs vary depending on the size of the roof, roofing material, pitch, accessibility, and the amount of organic growth present. Our roof washing services start at $399 for many one-story asphalt shingle roofs up to approximately 2,000 square feet. We provide free estimates with upfront pricing and no hidden fees.

Does homeowners insurance cover roof cleaning?

In most cases, homeowners insurance does not cover routine roof cleaning because it is considered preventative maintenance. However, maintaining a clean roof can help protect your investment and may reduce the risk of premature roof deterioration caused by algae and organic growth.

Can algae damage shingles?

Yes. The black streaks commonly seen on asphalt shingle roofs are often caused by Gloeocapsa Magma, a type of blue-green algae that feeds on the limestone filler found in many shingles. If left untreated, the algae can continue spreading and contribute to the premature aging of your roof.

Is bleach used during roof washing?

Our roof washing process uses a professional cleaning solution that contains sodium hypochlorite, which is commonly referred to as bleach. When properly diluted and applied using a soft wash system, it effectively eliminates algae, bacteria, mold, and mildew. We also follow plant protection procedures throughout the cleaning process to help protect your landscaping.

How long does roof cleaning last?

Most roofs remain clean for three to five years, although this varies depending on tree coverage, shade, humidity, rainfall, and surrounding vegetation. Homes with heavy shade or nearby trees may require cleaning more frequently.

What time of year is best for roof cleaning?

Roof washing can be performed year-round in Florida. Many homeowners choose to have their roofs cleaned before hurricane season, before listing their home for sale, or as part of their annual exterior home maintenance. If your roof has visible black streaks or algae growth, it's a good time to schedule a cleaning regardless of the season.

How long does roof cleaning take?

Most residential roof washing projects are completed in two to four hours. Larger homes, steeper roofs, tile roofs, or properties requiring additional preparation may take longer.

Will my plants be damaged?

Protecting your landscaping is one of our top priorities. Before, during, and after the roof washing process, we pre-water plants, continually rinse surrounding landscaping, manage downspouts, and apply a plant neutralizer when appropriate. While no exterior cleaning company can guarantee zero impact in every situation, we take every reasonable precaution to protect your property.

Do I need to be home during the service?

Not necessarily. As long as we have access to the exterior of the property and an available water source, many homeowners choose not to be home during the service. We will communicate with you before and after the job to ensure everything is completed to your satisfaction.

How often should I have my roof cleaned?

We generally recommend professional roof washing every three to five years. However, homes with significant tree coverage, heavy shade, or persistent moisture may benefit from more frequent cleanings to prevent algae and organic buildup.

Does roof cleaning increase home value?

While roof cleaning does not directly increase your home's appraised value, it can significantly improve curb appeal and create a strong first impression. A clean, well-maintained roof helps your home look newer, demonstrates pride of ownership, and may make it more attractive to potential buyers.
