How to Kill Roof Moss Naturally With No Chemicals

1. Remove Debris:

- Clear any debris, leaves, and dirt that have accumulated on the roof. This will help prevent the moss from reoccurring and provide a better surface for treatment.

2. Scrub with a Stiff Brush:

- Use a long-handled, stiff-bristled brush or broom to scrub the moss vigorously. This physical removal will loosen and dislodge the moss.

3. Rinse with Water:

- Rinse the roof thoroughly with water from a garden hose or pressure washer set on a low pressure to wash away the loosened moss and debris.

4. Apply White Vinegar Solution:

- Prepare a mixture of equal parts white vinegar and water. This solution is effective in killing moss without causing damage to the roof or nearby plants.

- Spray the vinegar solution liberally over the entire moss-affected area. Let it sit for at least 30 minutes to an hour.

5. Scrub Again:

- After the vinegar has had time to work, scrub the roof again with a stiff brush to loosen any remaining moss.

6. Rinse with Water:

- Rinse the roof thoroughly with water to remove any residual vinegar and loosened moss.

7. Apply Copper Sulfate Solution:

- Prepare a mixture of copper sulfate and water according to the package instructions. Copper sulfate is a natural moss killer, but it should be used with caution and protective gloves due to its potential toxicity.

- Use a spray bottle to apply the copper sulfate solution to the areas where the moss was growing.

8. Let It Dry:

- Allow the copper sulfate solution to dry completely. It may take several hours or overnight.

Note:

Moss control and prevention are ongoing tasks. You may need to repeat these steps periodically to keep your roof moss-free. Additionally, make sure to address any underlying conditions such as excessive shade or poor water drainage that may contribute to moss growth.

Remember, safety is paramount when working on a roof, so take precautions to prevent falls and follow proper ladder safety guidelines.
