The roof of your home is one of the most important features that it has, protecting you from rain, shine, snow, and more. It’s important that this is in top condition to provide you and your loved ones with the security you need. However, there are times when your home roof might be plagued by a certain substance.

Mold and algae are both very similar substances that can appear on your home’s roofing. Both affect the look of your home and also damage your roof. But, while they both look quite similar, there are several differences that should be noted.

As a homeowner, be aware of how to differentiate the two, especially when the time comes that you need to get it professionally removed and prevented. Keep reading to learn more.

What Is Algae?

Algae can grow in various places, but it can take advantage of your roof during the summer months. It can grow on your home roof in less than a week and can progress to cause damage to your roof, your home, and more.

Even the tiniest patch of algae can be an issue because it can cause leaks in your roof. Most homeowners won’t even know about these leaks for a while until it gets cold outside and your roof starts to truly act up. 

What Is Mold?

Mold can start to develop when water sits on your home’s roof, resulting in much damage to your home and its foundation. Mold can grow on any part of your home, even the inside. Mold has been known to be the cause of certain illnesses and infections.

Mold tends to grow in a more thick, round pattern, while algae can grow in a more thin and wavy way. Plus, mold is considered a fungus that thrives in moist and humid environments, which makes it more of a part of nature and its growth.

How Different are Mold and Algae?

As mentioned above, the appearances of mold and algae are slightly different. The effect they have on the roofing also varies. While both of these substances can cause damage to your roof and home, the impact of algae is more short-term in comparison to mold.

Algae builds up quickly in creating leaks but can be washed away relatively easily. Mold, on the other hand, can cause problems that can last longer. The germ can grow over time thanks to moisture, causing some serious damage to your home and everyone living in it.

How Are Algae and Mold Removed?

While removing algae from your home’s roof can appear to be more harmless and doable, both that and mold is something that you might want to research a little more and call the roofing professionals for. If you’re having a difficult time in identifying whether you have algae or mold on your roofing, it truly is best to leave whatever variant that is to the experts instead.

How Are Algae and Mold Prevented?

Your best bet for preventing algae and mold from forming on your home’s roofing is to use an effective roof maintenance service. The professionals will clean the roof of your home and remove any algae and mold that might grow on it. They’ll also use their knowledge to prevent any mold and algae from returning, making sure the roof will stay clear.


Understandably, having mold or algae growing on your home’s roof is something you’d want to get removed and prevented at any cost. Fortunately, the professionals can help you with that, ensuring that your home’s roofing is in tiptop condition.
