What You Should Know About Moss And Algae On Your Roof

Beverley Hall

If your home is in the shade the majority part of the day, or you live in a wet, humid part of the country, then there is a good chance that your roof will have moss or algae on it. What exactly do both of these need to thrive? Really, all moss and algae need to grow is warm to cool air, shade, and moisture. Keep reading to learn the difference between moss and algae, the dangers they pose to your roof, and how to get rid of them.

The Difference Between Moss and Algae

It is important to understand that moss and algae are two different things. Moss is a plant, whereas algae is not. Moss will accumulate in small mounds on your roof. If it grows and is not treated, it will continue to build up into round tufts. During the wet seasons of the year, it will be green. However, during drier times of the year, the moss may turn a green-brown color.

Algae is an organism that is spread by spores. It can be many different colors, including green, brown, blue, or gray. It will grow flush against the fixtures and shingles. Generally, it will show up on the roof in streaks and move down the roof vertically.

What Kind of Damage Can Be Expected?

Just as algae and moss are two different things, they also cause two different kinds of damage to your roof. If your roof system is highly reflective, the growth of algae can impact its ability to properly reflect the rays of the sun. If you have an energy-efficient roofing system, this could result in you paying more for your heating and cooling expenses.

Moss can be particularly damaging to your shingles, especially if they are wood shake or asphalt shingles. Shingles are designed to lie flat against your roof to encourage adequate water drainage. Over a period of time, moss can accumulate up the side of the roof, resulting in the lifting and/or curling of the shingles. Unfortunately, this can cause moisture damage, water intrusion, wood rot, as well as roof leaks.

How to Prevent the Growth of Algae and Moss on Your Roof

Regardless of your climate, there are many things you can do to prevent the growth of moss and algae on your roof. First, you can ensure that any overhanging trees are trimmed regularly. This will help to prevent moisture from being trapped after rainfall and avoids your roof from being overly shaded. It is also important to remove any debris that accumulates on the roof, particularly after storms. Debris will cause moisture to be trapped against the roof, creating the ideal environment for algae and moss to grow.

For more information, contact a roofing contractor in your area. A roofing contractor can inspect your roof for damage and recommend any necessary repairs.

Learning All About Roofing Materials

Hi, I'm Dwight Eberstark. I am crazy about all of the different types of roofing materials available today. While upgrading the roof on my home, I looked into the material options in great detail. I studied all of the different metal materials used to create modern shingles. I also looked into switching to asphalt, wood or tile shingles. I eventually settled on bronze shingles designed to last for decades. Instead of aging, the bronze finish just continues to improve. I also switched to metal gutters that make a beautiful sound when the rain falls onto the surface. I would like to share my passion for roofing materials through this site. Thank you for coming by.
