The presence of moss on your roof, while potentially adding a quaint, cottage-like appearance to your home, poses a significant risk to your shingles, potentially leading to costly roof repairs. Prompt removal of moss upon first notice is highly advisable to prevent damage.

Moss can cause considerable and lasting harm to both the external surfaces and the underlying structure of your home. If you see moss on your roof, it is crucial to address it promptly to mitigate any potential damage.

How to Identify Moss on Your Roof?

Moss on your roof might not be immediately visible from a ground-level inspection. To conduct a more thorough examination, consider using binoculars, or for a more advanced approach, a drone can provide a comprehensive perspective. 

Regardless of the method chosen, it's important to inspect the entire roof, paying particular attention to areas that are typically shaded, as these are more prone to moss growth.

Identifying moss growth on your roof is generally straightforward. You'll observe green, fuzzy patches nestled between shingles or on metal roofing surfaces. In addition to moss, roofs can also host algae, which manifests as black spots on the roof's surface. Another potential sighting is lichens, which typically appear as green plaques that might be flat or have a raised, textured surface.

Moss-Removal Options: Commercial Products and DIY Solutions

When it comes to moss treatment, there are both commercial products and DIY solutions available. Commercial options like Wet and Forget Liquid Mold Remover and Bio-Advanced Moss and Algae Killer offer convenient, ready-to-use formulas that can be applied directly to affected areas. These products often require specific mixing and application instructions for effective and safe use. 

On the other hand, DIY solutions provide a less toxic alternative, with common recipes including diluted chlorine bleach or oxygen bleach solutions, and even mixtures using household items like Dawn dish liquid or white distilled vinegar. 

DIY Solutions:

  • Chlorine Bleach Solution: Mix one quart of bleach with one gallon of water and 1/4 cup of heavy-duty cleaner like trisodium phosphate. Ensure proper dilution to prevent plant damage. Avoid mixing with ammonia-based cleaners to prevent toxic fumes.

  • Plant-Friendly Solution: Combine 1 cup of oxygen bleach with 1 gallon of water. Alternatively, you can also mix 8 ounces of Dawn dish liquid or 1-1/2 to 3-1/2 cups of white distilled vinegar with 2 gallons of water.

  • Application: Use a pump garden-style sprayer for application. For safety while working on a ladder, consider a backpack-type sprayer.

How To Remove Moss from Roof Tiles and Shingles

Below is an easy process of removing moss from your roof tiles or shingles with our simple and clear guidelines. 

Step 1: Prepare the Area

Before beginning, dress in old clothes, safety glasses, rubber gloves, a cap, and non-slip shoes for protection. If you'll be working at the peak of your roof, have a safety rope or harness ready. Protect nearby plants with plastic sheeting. Securely position a ladder, grab a hose, and then ascend to the roof.

Step 2: Wet the Roof

Start by dampening all moss-covered areas with water. Always spray from the roof’s peak downwards to ensure the water flows off. This approach prevents water or tools from lifting or damaging the shingles and tiles.

Step 3: Gently Clean the Shingles

Before using any moss-removal products, gently scrape or remove the moss from the shingles or tiles using a scrub brush (available for $3-$20 at The Home Depot) or a long-handled soft-bristle brush. Tackle one small section at a time for better control of the brush and cleaning motions. Brush downwards to avoid damaging the shingles.

Step 4: Apply Moss Remover

If necessary, apply a chemical moss remover using a pump sprayer ($32 from Walmart) or a large spray bottle. Thoroughly soak the moss and leave the solution on as per the manufacturer's guidelines. For homemade solutions, a 20-minute setting time is usually adequate.

Step 5: Rinse Off

Return to the roof with a hose to rinse away the solution and the loosened moss. If any moss remains, use the scrub brush to remove it, then rinse the roof again.

Step 6: Power-Washing (Optional)

An alternative is to use a power washer. However, ensure that the shingles and tiles are intact, as high-pressure water can exacerbate any existing damage. When using a power washer, stay above the moss to direct the water downwards. Always use the lowest pressure setting to avoid damage.

How To Prevent Moss on a Roof?

To prevent moss growth on your roof, ensure it receives ample sunlight. This often entails pruning back any trees that overshadow your home, a measure that also aids in reducing the risk of storm damage. 

Regular gutter maintenance is crucial for promoting proper water drainage from your roof. Additionally, as previously noted, installing metal strips at the peak of your roof on both sides can effectively discourage moss from developing over time. These preventative steps can help maintain the integrity and longevity of your roof.

Key Takeaways: Best Way to Remove Moss From Your Roof

The effective removal of moss from your roof requires a comprehensive approach that combines various techniques, including gentle brushing, proper rinsing, and the application of appropriate moss-killing solutions. 

However, the job doesn't end there. To ensure a moss-free roof in the long run, consistent and thorough maintenance is essential. This entails regular inspections to identify any potential moss regrowth, as well as timely cleaning to prevent the accumulation of debris that may foster moisture and moss development.
