In fairytales and fantasy movies, we come to expect quaint villages with lush green, moss-covered roofs. In reality, if we spot a thick layer of moss forming on our actual roof, it probably spells trouble.

Dirt, mold, mildew, and insect nests are just a few problems that can accompany significant moss growth, and any combination of these problems can run thousands of dollars to correct.

Why is moss growing on your roof?

Typically, when a home’s roof is under damp, shaded conditions, thick greenery — such as moss, mold fungus, or algae — can form and begin to eat away at your home’s roofing material. Moss usually begins to form a thin green layer on and between shingles, making it tricky to spot without routine roofing inspections. However, over time, moss collects water and can lift those shingles as it grows, allowing water to seep underneath and causing rot damage, roof leaking, and more.

How to remove moss from the roof?

While moss is very good at clinging to any surface it’s on, we use professional ready-made solutions for removing moss from the roof.

We let the solution remain on the moss for up to about 45 minutes, which should kill the moss. Then using a scrub brush or push broom, we scrub the roof down thoroughly, downward to not damage your roof’s shingles.

It is often dangerous for many homeowners with high rooftops to navigate and clean their roofs alone, so professional roofers are recommended.

Power washing to remove moss is also best left to professionals with expertise and equipment necessary to ensure no water damage is caused to the roof.

How to prevent moss on the roof?

Fortunately, there are also a few things you can do if you are seeking solutions for how to stop moss growing on your roof.

First, if you can trim back branches that provide sunlight to your roof, that may stop its growth.

Second, you may also try installing specialized copper, galvanized metal, or zinc strips on the edge of your roof, which are designed to fight off the moss. These strips strip work by oxidizing and washing down the roof when it rains, creating a difficult surface environment for moss to grow.

Finally, regular roof inspections are perhaps the surest way to remove moss from your roof. Roofers typically make sure your roof is draining properly, ensuring conditions do not allow for moss growth. It is recommended that your roofers thoroughly inspect for moss and pests, and clean your gutters at least yearly to avoid the backup water that could attract moss.
