Why is vinegar so effective For Removing moss?

Because vinegar contains a very corrosive acidic substance,(CH3COOH), also known as (ethanoic acid), it acts as a natural weed killer when applied directly to Moss but how does it do this?

Well, mosses absorb water directly through their liverworts (leaves), and the moisture is then carried to their internal systems (xylem and phloem) the base of the plant, which is used in photosynthesis.

When pouring vinegar directly on top of the plant the liverworts will naturally absorb the vinegar. Once it reaches the (xylem and phloem) the (ethanoic acid) will start to break down the moss from the inside out as a result causing it to dry out and die.

In addition, vinegar prevents moss from being able to photosynthesize, which is necessary for the plant to grow. So if you want to protect your roof from pesky moss growth, be sure to try vinegar!

What are the best types of vinegar to use on a roof?

There are many different types of vinegar that can be used on a roof, depending on their specific properties and their intended purpose.

Ultimately, the best type of vinegar will depend on your specific needs and preferences, so it is important to do some research before choosing what to use.

Nevertheless, all types of vinegar have the potential to remove the moss and make your roof look clean and well-maintained.

Here are some examples of different types of vinegar you can use on your roof:

  • Horticultural Vinegar
  • White Distilled Vinegar
  • Malt Vinegar
  • Cleaning Vinegar

Horticultural Vinegar

Horticultural vinegar is one of the most effective ways to remove moss from a roof as it has a very high acidity level. This makes it ideal for killing moss, but you must be careful not to damage your roof in the process.

This is a great option for large roofs or those with thicker types of moss.

White distilled vinegar

The perfect choice to deal with moss is white distilled vinegar. It’s acidic, has little smell, and has no color. It doesn’t get any better than that!

Other options work in a similar fashion – but may have some downsides; for example, a strong smell or may discolor your roof if you’re unlucky.

You’ll have no such problems when using distilled white vinegar – that’s why it’s the best option.

Malt vinegar

Malt vinegar is the cheapest option on this list – and the cost-effective way to make moss go away.

The problem with malt vinegar is that it may not be as effective as white distilled vinegar because it’s not as acidic.

You’ll have to figure out whether you want to use malt vinegar or white vinegar.

The easiest way to do so is to see how big of a problem you have. For small quantities of moss, malt vinegar will do. For anything else, you may want to buy white distilled vinegar.

Cleaning vinegar

You’ll find different opinions on using cleaning vinegar to kill moss. There’s a reason for that! This type of vinegar is way too acidic – and may damage any surface it touches.

It’d be better if you chose white distilled vinegar or any other option on this list. You can use cleaning vinegar straight away if you want something that will remove every bit of moss you have on your roof.

Simply put, cleaning vinegar is the nuclear option. Make sure you’re ready to use it, though.

How much vinegar will you need to kill moss On A Roof?

The amount of vinegar you’ll need will depend on the size of your roof and the severity of the moss problem. For a small roof, 1/2 gallon of vinegar should be sufficient.

For a larger roof, you may need up to 1 gallon. If the moss is particularly thick, you may need to use a higher concentration of vinegar.

10% vinegar is typically used for cleaning purposes, but 20% or even 30% vinegar can be used for killing moss. Just be sure to exercise caution when using high concentrations of vinegar, as they can be harmful to plants and animals.

  • Step 1: Inspect the area: Before you start, take a look at the mossy area and what you are working with.

  • Step 2: Deal with debris: Once you’ve inspected the area, it’s time to deal with any debris that may be present. This includes leaves, twigs, or acorns. First, grab a soft bristle brush, a knife, and a plastic bag too. Remove everything that doesn’t belong up there and put it in the bag.
  • Step 3: Brush your roof: Now comes the hardest part. Brushing! Take your time, and don’t rush it. Otherwise, you will be exhausted before you finish. Wear gloves, goggles, and a face mask when you do.

Alternatives to vinegar

Vinegar is a great way for killing moss on roofs, but it’s not the only option. There are a number of products on the market specifically designed to kill moss, and many of them are just as effective as vinegar.

  • Moss Killers
  • Baking Soda
  • Sea Salt
  • Bleach
  • Dish Soap

Moss Killers

Moss killers are typically some sort of chemical that will kill moss on contact. Many of these products also contain algicides, which help to prevent the growth of algae.

While moss killers are effective at killing moss, they can be harmful to animals and plants if used incorrectly.

So it’s important to read the label carefully and follow the instructions before using any type of chemical on your roof.

Baking soda

Baking soda works similarly to vinegar, with one exception you don’t have to spray it around instead, you have to sprinkle it around. That means there’s no need to mix it with water.

You can mix it with water if you want to. Half a pound of baking soda in a gallon of water will do the trick.

Using baking soda is far from a bad option – and probably the best alternative to vinegar you will find on this list.

Sea Salt

Sea salt is very effective against moss – but not the kind of weapon you want for this battle. Most people use sea salt to kill moss found on gravel, not roofs.

Then again, it’s worth the shot if you have nothing else to help you.

You can sprinkle some salt directly on top of the moss for the best results do this on a hot day as the salt will be more effective! Although this option is not as effective as vinegar it can still do the job.


Bleach is an aggressive yet effective household option to deal with moss. However, you cannot use it alone because of how strong it is. So it’s always safe to mix it with water first.

The right ratio is four ounces of bleach for every gallon of water. Spray that on moss and wait for a couple of hours. Bleach is way too aggressive to leave it for longer than that – and that’s why most people prefer less damaging options like vinegar.

Dish soap

Not every dish soap will help you remove moss. The ones that work are somewhat strong, so you’ll have to mix them with water. The ideal ratio is half a gallon of water for every ounce of dish soap you have.

Most people prefer vinegar over dish soap when dealing with large quantities of moss.

Then again, if you have to get rid of a small patch of moss, dish soap is not a bad option to consider, especially if you don’t have vinegar around.

Final Thoughts

So not only do you know how to remove moss from your roof using vinegar but you also know that it’s safe to use and what your alternatives are.

Be sure to follow the steps and be patient while waiting for the moss to die off. Don’t forget to rinse your roof afterward until all the vinegar is off the roof.
