Moss commonly thrives in environments that are damp and shaded. Moss absorbs the moisture from the damp environment and establishes roots on your roof causing the beginning of roof degradation. The roots can lift up shingles and constant moisture can lead to bacteria and mold growth. This eventually can lead to holes in your roof and leaks into your home. It is also dangerous to walk on a moss covered roof because it makes surfaces very slippery when wet. It’s very important to monitor for moss growth and treat as needed. If you live in an area that is frequently damp or in the woods, you should take steps to prevent moss growth on your roof.

There are various things you can do to prevent moss from growing on top of the roof. Below is a list of some of the most basic and some you may never have heard of before but work well.

String copper wire across the roof in intervals using nails or screws on the side of the roof (Do not hammer the nails or place the screws through the asphalt shingles. Place them on the side of the roof, possibly in the faucet. Keep the roof clean of debris on a regular basis.
