The roof is an essential part of any structure; it is the protective shield of the home. We always want our roofs to look good and stay strong. Sometimes we see a green color layer on our roofs which gives them a dirty and unkempt look. The layer is called moss and it could damage the entire roof if you do not take it as a serious issue at the beginning. So what you should do if you see moss on your roof too? Read on to learn more!


If you see any kind of moss growth, that is any sort of algae, fungus, lichens, etc., the first thing you should do is call a professional for an inspection of your roof. The professional will tell you about the actual condition of your roof. If the roof needs a complete replacement but you do a cleanup without taking an expert’s advice, it may be a complete waste of your time and energy. To avoid this situation, call professionals for an inspection and listen closely to their advice.


Once you spot moss, there is always the option of trying to clean it up on your own. If you can reach your roof properly with a ladder, then you can start cleaning. It is always suggested to hire professionals to clean the roof due to the dangerous nature of this, but it can be done on your own. Here are some methods that will help you out:


The first step is to scrub off the algae. Do not use any harsh detergent to scrub your roof because instead of getting rid of the moss, you’ll end up damaging your roof permanently. This will cost significantly more than you could save by trying to clean it yourself.

The best way to scrub is to use a soft scrubber. Scrub the roof with mild pressure, otherwise, you’ll end up creating scratches on your beautiful roof and may increase the spreading of moss.


Once you are done scrubbing, wash the roof so that the scrubbed-off moss gets drained down from the roof. Always use a standard spray hose attachment to rinse off your roof. Do not attempt to pressure wash the roof, it will damage the roof severely.

Killing spores

After you have rinsed the roof still there will be some spores of moss left behind. Killing them at this point is important, otherwise, it may lead to the growth of moss again in a few weeks.

There are special spray solutions available on the market for killing spores. But if you wish to use something which will be available at your home, you can use a solution of 50/50 water mixed with vinegar or bleach. We recommend letting this solution stay on the roof for 15-20 minutes after spraying. This will make sure that all the spores are killed.
After 15-20 minutes, rinse the roof with a gentle spray. The solution of vinegar or bleach is harmful to plants as well, so we suggest keeping your plants safely away from the roof edges.


Prevention is always better than a cure. The best way you can prevent your roof from having moss develop is by allowing it to get exposed to the sun. You can trim off the branches of the trees covering your roof. This way you will protect your roof from limbs falling on it and also animals taking shelter in the attic.

Regular cleaning of the roof gutters should be done as well because leaves, sticks, and other organic matter can lead to the development of roots or spores on the roof. You should also make sure that the drainage on your roof is in proper condition and clean. Improper drainage leads to moisture, which leads to the growth of moss. You can apply a zinc coating to protect your roof from corrosion.


As we mentioned earlier, we recommend hiring professionals for roof cleaning. They know their job very well. Also, they have special tools to clean your roof appropriately. DIY cleaning can lead to hazardous accidents, which will definitely cost you more than hiring professionals. Either way, we recommend you be as careful as possible during this process.
