How to Get Rid of Algae on Your Roof
We all know that roofs can collect dirt and leaves, but did you also know that it can trap algae? It may be hard to notice depending on your roof’s structure, but it can easily build up various types of algae, lichens, and fungi bacteria over time. If you notice that your roof has a blue-green tint, you likely have an algae issue. And, if it’s left untouched, the algae can die and leave nasty dark stains on your roof. Let’s take a look at what causes roof algae and what can be done to get rid of it.
Causes of Algae on Your Roof
Algae tends to thrive in certain environments like hot, humid atmospheres, shady or damp areas, and under big trees. Additionally, since the algae on roofs are living, they need nutrients to survive—and sadly, the limestone filler in many shingles gives it the nutrients it needs to grow. In many cases, all it takes is one algae spore to land on your roof and make itself at home. If your roof is shaded or you live in a rainy climate, it could elevate the problem. Even if your home isn’t in a shady or wet area, clogged gutters can also contribute to algae on the roof, so it’s very important to schedule routine gutter cleaning as well.
How Algae May Affect Your Home
Aside from an undesirable appearance, algae on the roof may cause other problems as well. For example, it can devalue your home, damage underlying roof materials, and lead to wood rot and mold issues. You can learn more about wood rot causes and prevention by reading our blog article. Lastly, if you allow roof algae to fester, it can damage structural integrity and threaten your family’s health. Oftentimes, when algae turns into mold or mildew, it can become a harmful toxin to breathe.
How to Prevent & Remove Roof Algae
First, prevention is the best way to ensure your home is protected—make your roof an unhealthy place for the spores to grow by increasing the amount of natural sunlight that hits your roof. You can do this by trimming back branches or trees that provide excess shade. Additionally, you can schedule routine exterior maintenance with Labor Panes to ensure there’s no algae buildup over time.
