How Often Should You Clean Moss and Algae off a Roof?

Cleaning moss and algae is an important task for maintaining the longevity and durability of the roof. Moss and algae growths can trap moisture within the roof, often causing rot and leaks. Furthermore, they can be unsightly and cause a home to lose curb appeal.

While there is no definitive answer for how often one should clean moss and algae off a roof, we recommend homeowners do so at least once a year. More frequent cleaning may be necessary for homes in Vancouver, where there is heavy rainfall.

Can Moss and Algae Damage a Home?

Moss and algae can damage a home in several ways. As previously mentioned, they trap moisture within the roof, which can lead to rot and leaks.

Additionally, they can weigh down the roof, causing it to sag and potentially collapse. Finally, these growths can also clog gutters and downspouts, causing further water pooling on the roof.

For these reasons, we recommend cleaning moss and algae from a roof at least once a year.

What is the Best Way to Clean Algae and Moss From a Roof?

There are numerous ways to clean moss and algae off a roof. One is to physically remove it with a brush. The most effective way is to use a combination of environmentally friendly cleaning solutions and a soft washer to remove moss and algae.

With soft-washing, you can avoid the potential damage caused by power-washing, which can strip away shingles and leave your home susceptible to leaks.

If you have moss and algae on your roof, we recommend that you have it professionally cleaned at least once a year.
