Best Way to Clean a Tile Roof

Cleaning a tile roof is an essential part of roof maintenance to ensure its longevity and curb appeal. Here’s a step-by-step guide on the best way to clean a tile roof:

Before starting, ensure you have all necessary safety equipment, such as non-slip shoes, a stable ladder, and a safety harness if required. If you’re not comfortable working at heights, it’s best to hire a professional.

Inspect the roof for any cracked or broken tiles. Replace these damaged tiles before proceeding with the cleaning.

Remove leaves, branches, and other debris from the roof using a soft-bristled broom or leaf blower. Be gentle to avoid damaging the tiles.

Before applying any cleaning solution, lightly spray the roof with water using a garden hose. This step helps to cool down the tiles and prevents the cleaning solution from being absorbed too quickly.

Avoid using harsh chemicals or high-pressure washers as they can damage the tiles. Instead, opt for a mild roof tile cleaning solution. A mixture of water and mild liquid dish soap or a specialized tile roof cleaner can be effective. Always follow the manufacturer’s instructions for any cleaning product.

Using a low-pressure sprayer or a soft-bristled brush, apply the cleaning solution to the roof. Work in small sections to ensure the solution doesn’t dry on the tiles.

For stubborn stains, use a soft-bristled brush to scrub gently. Avoid using abrasive tools that can scratch or damage the tiles.

After letting the cleaning solution sit for a few minutes, rinse the roof thoroughly with a gentle stream of water. High-pressure washers can be too aggressive and cause tile damage, so use a regular garden hose instead.

Inspect the roof for any remaining stains. If some stains persist, you might need to repeat the cleaning process for those areas.

Consider installing copper or zinc strips along the roof’s ridgeline to help prevent algae and moss growth in the future. As rainwater washes over these metals, they release compounds that inhibit the growth of organic matter.

Remember, if you’re unsure about any part of the process or if your roof is particularly delicate, it’s always best to hire a professional roofer or professional roof cleaners. They have the expertise and equipment to clean your tile roof safely and effectively.

How Often Should You Clean Your Roof

The frequency of roof cleaning depends on various factors, including the type of roofing material, the climate in your area, and the amount of debris that accumulates on the roof. Here are some general guidelines for how often you should clean different types of roofs:

  • Tile Roofs: Tile roofs generally require cleaning every 2 to 3 years. Tiles are durable and resistant to algae and moss growth, but they can still accumulate debris and dirt over time.
  • Asphalt Shingle Roofs: Asphalt shingle roofs should be cleaned approximately every 3 to 5 years. These roofs are susceptible to algae growth, especially in humid or moist climates, so regular cleaning can help maintain their appearance and functionality.
  • Metal Roofs: Metal roofs are relatively low maintenance and can go longer between cleanings. Cleaning every 5 to 7 years is usually sufficient for most metal roofs.
  • Wood Shake Roofs: Wood shake roofs need more frequent cleaning, typically every 2 to 3 years. They are prone to moss and mildew growth, so regular cleaning is essential to prevent damage.
  • Slate Roofs: Slate roofs are durable and can last for decades, but they can still benefit from cleaning every 5 to 7 years to remove debris and maintain their appearance.
  • Flat Roofs: Flat roofs should be inspected and cleaned at least once a year. Debris, leaves, and standing water can cause issues on flat roofs, so regular maintenance is crucial.


Remember that these are general guidelines, and the actual cleaning frequency may vary based on your specific circumstances. If your roof is located near trees that shed a lot of leaves or in an area with high humidity, you may need to clean it more frequently.

Regular inspections are essential as well. Check your roof at least once a year for any signs of damage or debris buildup. Early detection of issues can prevent more extensive damage and save you money in the long run.

Always prioritize safety when cleaning your roof. If you’re unsure about the condition of your roof or how to clean it properly, consider hiring a professional roofing contractor or a specialized roof cleaning service. They have the expertise and equipment to clean your roof safely and effectively.

Why Do Tile Roofs Need Cleaning?

Tile roofs need cleaning to maintain their appearance, prolong their lifespan, and prevent potential damage. Over time, debris like leaves, branches, and dirt can accumulate on the tiles, creating an environment conducive to the growth of algae, moss, and mold. These organic growths not only mar the roof’s aesthetics but also retain moisture, potentially leading to the deterioration of the tiles and underlying structure. Regular cleaning removes the debris and growth, preventing costly repairs and preserving the roof’s integrity. Additionally, clean tile roofs enhance the overall curb appeal of a property, making it essential for homeowners to invest in periodic roof maintenance.

How To Clean Your Roof Tiles with a Pressure Washer

A homeowner can take note of some helpful tips to keep their tile roof clean and well-maintained, along with suggestions for regular pressure washing services to maintain the overall appearance of their property. Cleaning your roof tiles with a pressure washer requires careful execution to avoid damage. First, clear loose debris with a broom or leaf blower, and pre-wet the roof to cool down the tiles. Use a pressure washer with a PSI of 1,200 to 1,500, equipped with a wide-angle nozzle. Start at the lowest pressure setting and work in sections, directing the spray downward along the roof’s slope. Maintain a safe distance from the tiles and avoid spraying upward to prevent water from getting under them. Be mindful of delicate areas, such as vents and flashing, and consider hiring a professional if you’re uncertain about the process. Regularly inspect and repair any damaged tiles after cleaning to maintain the roof’s integrity and longevity.

How To Clean Concrete Roof Tiles

To keep your concrete roof tiles clean, begin by clearing loose debris with a broom or leaf blower. Pre-wet the roof to cool down the tiles and avoid rapid absorption of cleaning solutions. Create a mixture of water and a mild detergent or specialized roof cleaner, and apply it with a low-pressure sprayer or a soft-bristled brush. Work in sections and allow the solution to sit for a few minutes, loosening dirt and grime. Use a gentle scrubbing motion to remove stubborn stains, but avoid aggressive brushing to prevent tile damage. Finally, rinse the tiles thoroughly with a low-pressure garden hose, directing the water downward along the roof’s slope. Regular cleaning of concrete roof tiles can help maintain their appearance and protect them from long-term damage.

How To Clean Tiles of Moss

To clean the moss from tiles, start by removing any loose debris and large moss patches using a soft-bristled brush or a plastic scraper. Mix a cleaning solution of equal parts water and white vinegar or use a commercial moss removal product. Apply the solution generously to the moss-covered tiles and let it sit for about 15-30 minutes to loosen the moss. Use a scrub brush or a pressure washer with low pressure to gently remove the moss. Work in small sections, using a gentle back-and-forth motion to avoid damaging the tiles. Rinse the tiles thoroughly with water to wash away the remaining moss and cleaning solution. To prevent moss regrowth, consider installing zinc or copper strips along the roof’s ridgeline to release moss-inhibiting compounds when it rains. Regular roof maintenance and keeping the surrounding area free of debris will also help prevent moss from coming back.
