How to Deal With Moss & Algae on Your Roof

Blog

Moss and algae are two of the most common plants that grow on roofs. It is really common especially in areas of the country that get a lot of moisture, such as the Pacific Northwest. If you have moss or algae on your roof, you should not leave it there and allow it to continue to grow and fester. Here is what you need to do to get rid of moss and algae on your roof.

#1 Why It Happens

Algae and moss grow on your roof because of the variety of circumstances that come together. To start with, if your roof is moist and the weather is cool, those are the ideal conditions for moss and algae to grow. Next, moss and algae spores have to land on the roof and find a favorable place to start growing. Once the moss and algae are in place, they continue to trap more moisture on your roof and contribute to conditions that cause these plants to thrive. Moss and algae create their own vicious cycle of growth once they latch onto your roof. 

#2 Long Term Damage

You don't want to let algae and moss continue to grow on your roof as they can contribute to and create long-term damage to your roof. Since moss traps moisture in place, it can lead to rot taking hold and ruining your roof and the sub-materials on your roof. Moss can also cause your shingles to get lifted up and out of place, which can allow water to leak into the sub-levels of your roof and cause additional damage to your roof. Moss and algae contribute to water damage ruining your roof and need to be dealt with right away before they progress.

#3 Cleaning It Away

You are going to want to clean the moss and algae off of your roof. There are various ways that you can clean off your roof. You can use a hose to spray off your roof using a spray attachment. Hopefully this will loosen and remove the moss and algae from your roof. After that, you can pour bleach on your roof where the plants were growing. Let the bleach sit for a few days, then clean your roof again. This should clean off your roof and kill the moss and algae in its track.

You can also use chemical formulas to clean off the roof and ensure the the moss and algae doesn't come back.

#4 Preventing It From Occurring Again

You can also take steps to prevent the algae and moss from growing back on your roof again. Cut back any branches that are growing over your roof and make it too shady. Make sure that you keep your gutters clean; when your gutters get backed up, it can create moisture conditions ideal for plants to grow on your roof. You may also need to install more roof vents to keep moisture away from your roof and make the conditions on your roof less ideal in the first place for moss and algae to grow.
