Why Moss and Algae Growth is So Bad on Your Roof


January 3, 2023

Moss and algae growth on your roof can be a serious problem. It’s not just an eyesore: moss and algae can damage your roof, eroding shingles and damaging the layers. The worst roofs for moss are those that get little direct sunlight exposure. Left untreated, algae and moss can become infested with insects that thrive in cool, moist environments. Even worse? Not only can moss and algae cause severe damage to your roof, but it can harbor small animals as well. It may be tempting to go up on the roof yourself to remove it—but don’t! The danger of moss goes beyond the cosmetic; it could cause serious structural issues with your home if left unchecked by professional roofers trained in dealing with these kinds of problems.

Here’s a closer look at why moss and algae are so bad on your roof.

Moss and algae growth can damage your roof.

Moss and algae can damage your roof in a number of ways. Here are some of the biggest concerns you should know about.

Over time, moss will grow up under the shingles and cause them to crack, allowing water to get into the roof. The water will then seep into the wood and drywall below, which can eventually lead to mold growth in your home and cause damage there as well.

Not only do moss and algae cause leaks in your property that may go unnoticed for some time but growths on roofs are also fire hazards due to their flammable nature—a single spark could ignite them into flames. Not to mention, both types of growths can be health hazards; some people are allergic to spores released by these organisms when they die (roof moss), while others have been found suffering from breathing problems due to exposure outside their homes.

Algae on your roof are more than just an eyesore.

Moss and algae on your roof are more than just an eyesore. Not only does it affect the appearance of your home, but it can also cause leaks and damage to your roof, leading to costly repairs. Unchecked, the decaying matter can build up in your gutters and cause them to clog and growth on your roof’s protective coating can allow moisture into the material itself, which makes it weak against weather conditions like wind gusts or hail storms.

So What Should You Do?

There are things you can do to prevent moss and algae from growing on your roof. First of all, make sure to keep your gutters clear of debris so that water can drain properly. Next, if you notice moss or algae growing in shaded areas like under trees or near the chimney, then use a broom to sweep it off before it becomes too much of an issue. The last thing we would recommend is calling a professional roofing company who will not only be able to tell whether or not your roof is at risk for damage but also provide solutions to get rid of these pesky plants once and for all.

In order to prevent further damage caused by these unsightly growths, you need both products that are safe and effective in removing them as well as skilled technicians who can remove the problem quickly without harming your roofing material or causing any discoloration in its appearance.
