How to Clean a Shingle Roof: Essential Maintenance Tips
How to Clean a Shingle Roof?
To clean a shingle roof, you can use a cleaning solution such as Roof Shampoo or a homemade solution of equal parts laundry bleach and water.
Start by spraying the cleaner onto the asphalt shingles and let it sit for 20 minutes.
Then, wash off the cleaner with water from a hose.
Next, use a medium-stiff bristled brush to scrub away any remaining moss, being careful not to dislodge the shingles.
Make sure to wear appropriate clothing and take safety precautions to prevent falls.
It’s important to note that black streaks on roofs are colonies of blue-green algae, and thick green patches are moss.
Moss can cause asphalt shingles to curl and blow off, potentially leading to leaks.
Algae can also affect the curb appeal of your home and may have a slight impact on its value.
To clean the roof, you can use a sprayer attached to a garden hose filled with equal parts chlorine bleach and water.
Allow the bleach solution to sit for 15 to 20 minutes before rinsing with clean water.
Take precautions to protect plants and shrubbery from the bleach solution.
It’s best to clean the roof on a cloudy, calm day with no threat of precipitation.
Additionally, ensure you take proper safety precautions, especially when cleaning steep slopes or multi-story houses.
Trim back overhanging branches to prevent the growth of moss and algae, and clear debris such as branches and leaves using a leaf blower.
Keep the gutters clean to ensure the roof remains dry.
Consult the manufacturer for cleaning instructions if your roof is made of different materials.
If needed, reapply the cleaning solution.
If you are unsure or require further assistance, consider hiring a professional for a free assessment and expert advice.

Did You Know?
1. Did you know that the lifespan of a shingle roof can actually be extended by regularly cleaning it? The accumulation of dirt and debris can cause the shingles to decay faster, but a thorough cleaning can help prevent this and extend the roof’s lifespan.
2. If you’re looking for an eco-friendly and cost-effective way to clean your shingle roof, try using a mixture of white vinegar and water. This solution helps to kill algae and moss without harming the environment or your wallet.
3. Cleaning your shingle roof not only improves its appearance but can also help reduce energy costs. Removing moss and algae allows the shingles to reflect more sunlight, which in turn keeps your roof cooler and reduces the need for excessive air conditioning.
4. A commonly overlooked aspect of shingle roof cleaning is the gutters. Clogged gutters can cause water to back up, leading to roof leaks and damage. It’s essential to clean the gutters regularly to prevent potential problems and maintain the integrity of your shingle roof.
5. While cleaning your shingle roof is important, it’s essential to use the right tools to avoid damaging the shingles. Avoid using a pressure washer or abrasive brushes, as these can cause granule loss or tear the shingles. Instead, opt for a soft-bristle brush or a roof cleaner specifically designed for shingle roofs.
Choosing The Right Cleaning Solution
Cleaning your shingle roof is crucial for its longevity and aesthetic appeal. Selecting the appropriate cleaning solution is a critical step in the process. Two main options are available: commercial roof cleaning solutions like Roof Shampoo or a homemade solution consisting of equal parts laundry bleach and water.
If you decide to use a commercial cleaning solution, follow the manufacturer’s instructions carefully as each product may have specific guidelines. Alternatively, if you prefer a cost-effective homemade solution, combine equal parts laundry bleach and water in a spray bottle.
Applying The Cleaning Solution
Once you’ve chosen your cleaning solution, apply it to the shingles. Start by spraying the cleaner onto the asphalt shingles at a low pressure. Make sure to cover the entire roof, focusing on areas with noticeable black streaks (blue-green algae) and thick green patches (moss). These organisms not only affect the curb appeal of your home but can also lead to serious damage if left untreated.
After applying the cleaning solution, it’s important to let it sit for about 20 minutes. This allows the chemicals to penetrate the algae and moss, breaking them down and making them easier to remove.
Scrubbing Away Moss And Algae
Once the cleaning solution has had enough time to work its magic, it’s time to remove the dirt, algae, and moss from your shingle roof. Using a medium-stiff bristled brush, carefully scrub away any remaining moss, taking care not to dislodge or damage the shingles.
A gentle circular motion is usually effective in removing the unwanted plant growth from your roof. However, if the moss or algae is particularly stubborn, you may need to apply a little more pressure. It’s important to strike a balance between effective cleaning and avoiding unnecessary damage to the shingles.
- Use a medium-stiff bristled brush
- Scrub in a gentle circular motion
- Apply more pressure if needed, but be cautious

Safety Precautions For Roof Cleaning
Cleaning your shingle roof requires proper safety precautions to prevent accidents and injuries. To ensure your safety, follow these guidelines:
- Wear appropriate clothing, including a long-sleeved shirt, pants, and sturdy shoes with slip-resistant soles.
- Consider using safety equipment such as a helmet, safety harness, and non-slip gloves.
- Take extra caution when working on steep slopes or multi-story houses. These situations can be particularly hazardous.
- If you’re not comfortable working at heights or have a complex roof structure, it’s recommended to hire a professional roofing expert. They will have the necessary equipment and expertise to perform the job safely.
Remember, safety should always be your top priority when cleaning your shingle roof.
Preventing Moss And Algae Growth
Prevention is always the best approach when it comes to moss and algae on your shingle roof. To reduce the likelihood of moss and algae growth, it’s important to take proactive measures.
Here are a few tips to keep in mind:
-
Trim back overhanging branches and foliage: By doing so, you allow more sunlight to reach the roof surface, which helps discourage the growth of moss and algae.
-
Keep your gutters clean and free from debris: Clogged gutters can lead to water overflow, creating conditions that are ideal for moss and algae growth. Regularly clearing debris such as branches and leaves using a leaf blower will ensure that your gutters remain clear and your roof stays dry.
Remember, by taking these preventive measures, you can protect your shingle roof from the growth of moss and algae, extending its lifespan and keeping it in good condition for longer.
Professional Roof Cleaning Services
In some cases, it may be best to leave the roof cleaning to the professionals. Hiring a reputable roofing company, such as George J. Keller & Sons, can provide you with expert advice and a thorough assessment of your roof’s condition. They specialize in roof replacements and offer a variety of shingle colors, including Hunter Green, Patriot Red, Slate, Weathered Wood, and Charcoal.
By engaging the services of professionals, you can ensure that your shingle roof receives the care it needs, prolonging its lifespan and maintaining its pristine appearance. Additionally, professional roof cleaning services can help you identify any underlying issues or damage that may require further attention.
