DIY: Removing Moss from the Roof

If the roof of your home is in a cool, damp and shaded environment then there is a threat that you need to look out for: Moss. When left unattended, as roofs often are, moss can grow wild, putting your roof at risk for big repair costs down the line. Fortunately, with a little vigilance and a lot of know-how, you can remove the moss from your roof and return it to its former glory. Read on for some DIY tips for removing moss from a roof that will help prevent long term damage and preserve your roof’s original appearance.



Just like cleaning the floor in your kitchen or vacuuming the floor in your living room, most problems can be prevented by cleaning regularly, and moss is no exception. While cleaning away the moss on the roof of your home, it’s best to remember that you are using dangerous chemicals and, while they will get rid of the moss, they could also cause damage to your skin if you’re not careful. When using abrasive chemicals, be sure to use protective gear, such as gloves, goggles, and clothes that you don’t mind getting a little messy. Since you’re going to be on the roof, you should also make sure wear slip resistant shoes, a safety harness or rope to help prevent any slips or falls.

Fortunately, when it comes to moss removal, most cleaners around your house will do, though one of your best choices is to use household bleach. Bleach that has chlorine in it should be strong enough for typical roof moss removal.

Pressure Washer

While there are many tools you could use to remove moss from your roof, one of the most effective options is to use a pressure washer. Pressure washer put out water at such high rates that moss will wash away incredibly easily. However, it’s important to make sure that you don’t overdo it as the strenghth of a pressure washer can easily cause damage to a roof that has already been compromised by moss build-up. If you’re not comfortable using a pressure washer, or are worried about the rental expense, you can also use a long-handled scrubbing brush to gently scrub away any lingering moss.

In doing this, you are bettering your chances of having a continuously moss-free roof.
