The Relationship Between Moss and Roof Leaks

April 19, 20233 min read

Moss growing on your roof can give your home a charming, natural look. But did you know that it can also cause significant problems like leaks and damage? Here’s what you need to know about the relationship between moss and roof leaks, and how to prevent it from happening to your home.

How Does Moss Grow on a Roof?

Moss is a type of plant that thrives in damp and shaded environments. Therefore, roofs that are frequently shaded or have low exposure to sunlight are most likely to develop moss. When moss grows on a roof, it can form a thick layer that traps moisture. This moisture can lead to leaks, as well as damage to the roof’s underlayment and structure.

Can Moss Cause Leaks?

Yes, moss can definitely cause leaks on your roof. The root system of moss can penetrate through the shingles, causing damage to the underlayment and roof deck. This can weaken the roof’s structure and make it more vulnerable to leaks. Additionally, the trapped moisture underneath the moss can cause the shingles to deteriorate more quickly, leading to even more damage and leaks.

Why is it Important to Remove Moss from Your Roof?

Removing moss from your roof is crucial to prevent leaks and extend your roof’s lifespan. Other reasons to remove moss include:

  1. Aesthetics: Moss can make your roof appear old and unkempt. Removing it can improve your home’s appearance, increase its value, and attract potential buyers.

  2. Energy Efficiency: Moss can absorb heat, which can increase your home’s temperature and cause your air conditioning to work harder. Removing the moss can help lower your energy bills.

  3. Prevent Damage: Moss can cause damage to the roof structure, which can be costly to repair. By removing it, you can prevent significant damage and save money in the long run.

How to Remove Moss from Your Roof?

If you have moss growing on your roof, you should remove it as soon as possible. Here are some methods to consider:

  1. Manual Removal: You can remove moss manually by using a brush or scraper. This method is best for small areas with less moss growth.

  2. Chemical Treatment: There are various moss-killing chemicals available in the market that you can use to remove moss from your roof. However, you need to follow the instructions carefully and use protective gear while applying them.

  3. Professional Cleaning: Hiring a professional roofing company is the safest and most effective way to remove moss from your roof. They have the necessary tools and expertise to remove the moss and prevent any damage to your roof.

Preventing Moss Growth on Your Roof

Preventing moss from growing on your roof is the best way to avoid leaks and damage. Here are some tips to keep in mind:

  1. Trim Back Trees: Trees that shade your roof can create a damp environment that’s perfect for moss to grow. Keep your trees trimmed back to allow more sunlight to reach your roof.

  2. Clean Gutters: Clogged gutters can cause water to pool on your roof, which can encourage moss growth. Clean your gutters regularly to prevent this from happening.

  3. Zinc or Copper Strips: Installing zinc or copper strips on your roof can prevent moss growth. When it rains, the strips release ions that prevent moss from growing.

  4. Regular Roof Inspections: Regular inspections by a professional roofing company can help you identify and address any moss growth before it becomes a problem.

To Sum It All Up

Moss on your roof can cause leaks and other types of damage, so it’s important to remove it as soon as possible. Whether you choose to remove it.
