Why is Moss growing on my roof? (and How to Prevent It) - Roof Pros

Roof Pros • April 27, 2022

Moss is a common problem found on roofs. It can grow in shaded and moist areas, making it an issue for homes in climates with either too much rainfall or too little sunlight. If moss is left untreated, it can damage your roofing materials and shorten the life of your roof. Here's what you need to know about moss and how to prevent it from growing on your roof.



Why moss might be growing on your roof


Moss growth on roofs can be caused by a number of factors. In particular, the presence of high levels of moisture and shade can lead to moss development. This is because moss thrives in damp environments where it has plenty of room to spread out and grow. Additionally, areas that are shaded for long periods of time, such as under trees or other overhead structures, create a perfect environment for moss growth. Finally, if your roof has any loose shingles or other deterioration that allows water to seep into crevices, then this can also increase the likelihood of moss formation on your roof.


Is moss on roof tiles a problem?


Moss on roof tiles is not only unsightly, but it can also lead to serious problems. Moss retains moisture, which can cause the tiles to crack or break. In addition, moss can provide a foothold for larger plants, leading to damage to the roof. Lastly, moss can inhibit the flow of rainwater, leading to pooling and eventually leaks. While moss may seem harmless, it can actually cause significant damage to a roof. Therefore, it is important to remove it as soon as possible.


Common issues moss growth on your roof can cause:

- Damage to roofing materials

- Cracking or breaking of tiles

- Weakened support structure

- Pooling and leaks due to blocked rainwater flow

- Damage and stains on exterior walls

If you notice moss growing on your roof, it is important to take action and search for roofing contractors near me.


How do I remove moss on my roof tiles?


There are several different methods you can use to remove moss from your roof shingles. Before we recommend some common DIY methods, please note that all roofing projects should be performed by a licensed professional roofing company. Roofing is a dangerous job, and it is important to always safety first.


- Pressure washing: You can use a pressure washer for roof cleaning and removing moss. This method is effective, but it can also be damaging to your roof if not done correctly. Always point the pressure washer away from the house, and start with the lowest setting before working your way up.


- Chemical treatment: There are a number of chemicals on the market that can kill and remove moss. This is a common DIY solution, but keep in mind that these solutions can be dangerous if not used or applied properly. Make sure to thoroughly read all instructions before using any chemical treatments.


- Brush & Scrub: Another common method for removing moss from your roof tiles is to simply brush or scrub it away. This can be done manually using a rough-bristled broom, but more often a power washer will be used to speed up the process.


Methods to remove moss from parts of your roof or your entire roof can cause damage to your roof surfaces. We can't stress enough the importance of contacting a top roofing company in your area that specializes in roof repair and can help assess the issues you have with your moss covered roof.


How do I prevent roof moss from growing on my roof?


Roof moss growth is unsightly and can cause long-term damage to the roof shingles. There are a few things you can do to prevent moss from growing in the first place. One method to prevent moss growth is to make sure that your gutters are clean and free of debris. Roof moss needs moisture to grow, so clogged gutters can provide the perfect environment for it to thrive. Another thing you can do to prevent moss growth is to trim back any trees or shrubs that are touching your roof. This will help to improve air circulation and reduce the amount of moisture that stays on the shingles. Finally, you can treat your roof with a moss-resistant solution. These products contain elements which act as a natural moss repellent. By taking these steps, you can help to keep your roof moss-free all year long.
