Your roof plays a fundamental role in protecting the integrity of your home. Unfortunately, it’s vulnerable to several damaging elements on a daily basis, including algae. This is because algae trap in moisture, which can cause your roof shingles to deteriorate prematurely. If you notice algae growth on your roof, it’s important to have it removed right away and take action to keep it from coming back. Below is an overview of what causes roof algae and how to prevent it.

Why Algae Grows on Roof Shingles

Algae spores are airborne, which means they’re easily spread across rooftops by the wind, insects, and animals. Algae thrive in damp, shaded areas. If your roof doesn’t receive much sunlight due to overhanging trees, algae can grow and cause roof rot. Algae also like moisture in gutters and will feed off any organic debris that may accumulate on your roof shingles. 

Preventative Steps You Can Take 

Removing algae from your roof isn’t enough to stop future growth. Regular maintenance is the key to preventing roof rot. This should include having the gutters cleaned at least twice a year to allow for proper rainwater drainage. You should also trim back any trees that shade your roof to prevent new growth. Installing a proper ventilation system will slow the moisture accumulation and block new algae from forming. If it’s nearing time for a roof replacement, you may consider installing algae-resistant roof shingles. They are made with algaecides and fungicides to specifically help deter algae growth.
