Your property may appear to be straight out of a storybook if your roof is overgrown with heavy moss. Aside from that, moss on your roof will deteriorate your shingles and cause damage to your entire roof. Moss operates like a sponge, absorbing moisture from its surroundings on a continual basis.

If the moss is in small places, you can save your roof, but if it becomes a thick covering, it can cause leaks and shingle damage. If left untreated for an extended period of time, you will almost certainly have to replace your entire roof. Learn how much it costs for roof replacement.

If you’ve got moss growing on your roof, you don’t have to wait for it to form a thick layer before you can start dealing with it. A lot of dry and liquid products can be used to clean your roof from moss.

Why Is Moss Growing On My Roof?

It is ideal for moss to thrive in damp and cool conditions. If your roof is shaded by trees in your yard or other structures nearby, it is more likely that it will grow on it. Mist can linger and moss can grow in environments like these.

Moss is a plant that does not absorb water from its roots, but instead its leaves. Moss reproduces with tiny seeds that are scattered around and eventually make their way onto your roof by wind, birds or other small animals.

The small size of the spores makes it easy for them to get in between roof shingles. It can spread across the entire roof, growing to be a couple of inches thick.

Why Is Moss Bad For Shingles?

Moss grows in damp conditions and attracts water like a sponge. The moss can cause the lower levels of roofing felt and structural elements to be damp, because it can easily make its way under the roof shingles.

This can cause rot on the roof. In a few months moss can destroy a roof. The damaging process of moss will be quicker if the shingles are made from wood, as wood is very porous, meaning that moss has more real estate to grow.

How To Kill Moss On Roof?

Hose Off The Roof With Water

Ensure the moss that is loose is dealt with sooner, the moss that is loose on the roof needs to be hosed off first. Water can get in between the shingles and cause a leak if it is not sprayed from the top of the roof. If you use too much water pressure, it can damage the shingles.

Make sure to scrub the moss off the shingles with a soft bristle brush after hosing down the roof. The brush needs to be moved in a downward motion to protect the shingles from being broken.


Apply Moss Remover

If there is still moss on the roof after hosing it down, use a moss cleaner to remove it. Moss cleaners are either a dry powder or liquid.

It is best to use a dry moss cleaner when there is a good chance of rain in the near future. The cleaner should be placed parallel to the roof ridge in horizontal lines.

Attach a garden hose to the container if you choose to use a liquid moss cleaner. Wait for the moss cleaner to start flowing and then let the water run. The cleaner should be applied from the top of the ridge. You might only need one bottle of moss cleaner or more if the roof is larger.


Rinse The Roof

The roof should be rinsed after moss cleaner is used. The moss should be loosened so it can be removed from the roof. A brush may also be required to get rid of moss.

If there is moss left in the shingles, you should get in touch with a professional to see if they can fix it or replace it.

What To Avoid When Removing Moss From A Roof?

There are a lot of bad suggestions when it comes to cleaning moss. The main concern about the methods is that they not only don’t clean the moss properly but also damage the shingles.

The limited warranty of the roof could be voided if the incorrect method of cleaning is used. If you don’t know how to clean or repair your roof, it’s a good idea to consult with a professional.


Using Harsh Materials

If you can, try not to use too much bleach and detergent. The chemicals damage the shingles and surrounding materials. The roof will leak and cause damage to the inside of the house if there is significant damage. Learn more what to do if your roof is leaking.

Plants and flowers near the base of the house could be sprayed with these harsh chemicals and ruined. Chemicals that cause more harm than good are the worst to avoid.



It might be a good idea to scrub the roof with a hard-bristle brush because the moss grips the shingles very strongly. By removing the asphalt shingles’ granules, scrubbing strongly can damage them.


Pressure Washing

Pressure washers can ruin the roof, so don’t use them to clean the moss.The pressure washers can break and lift up shingles. On asphalt types of roofs, pressure washers can strip the surface and ruin the performance.


How To Prevent Moss On Your New Roof?

Ensuring no parts of the roof are in the shade is a long-term solution. Make sure the roof gets as much direct sunlight as possible by trimming any branches that are making shade. It’s important to keep the roof and the gutter free of leaves and debris in order to be able to collect water.

The best solution for moss on the roof is to put metal strips on the ridge. The roof can be made unsuitable for moss, algae, and lichen by a strip of copper, zinc, or galvanized metal. Over time, metal will oxidize.

Because the strips are placed on the ridge of the roof, they will be washed down the whole roof every time it rains, making it less suitable for moss, algae, and lichen. That explains sometimes it is possible to see a gap in the moss next to a dormer.

It will take a long time for the inhibition of moss to start with the addition of a copper strip. Metal strips can’t prevent moss from coming in, they can only stop it from happening.
