Moss and algae are unsightly on any roofing system. Imagine having such a beautiful roof, only to be tarnished by black and green spots sporadically found around the shingles. As such, it’s important to know what causes them and how you can prevent them from starting in the first place. In this post, Pruden Roofing, a top commercial and residential roofing contractor shares roofing algae and moss prevention tips.
What Causes Algae and Moss?
Most homeowners panic when they see algae and moss growth on their roof, mistaking it for mold or mildew. These black discoloration streaks seen on many roofs across the country are actually algae. Algae forms in the presence of humid climates since it’s one of the most conducive conditions for algae growth.
The most common form of algae or moss is called gloeocapsa magma or blue-green algae. It protects itself from sunlight by creating a dark pigmented sheath, creating a dark appearance. Your roofing contractor will tell you that algae discoloration starts as small spots, then slowly turns into streaks on your roof’s surface. In fact, by the time the algae is visible, it might’ve been there for more than a few months or more.
Moss and Algae Prevention Tips
Here are a few tips you can use to prevent moss and algae from growing:
- Trim Back Tree Branches. Make sure that you trim back tree branches overhanging your roof to allow more sunlight to reach your roof to neutralize spores. Also, make sure that you clean off debris from your roof to create an environment that is less inviting for moss or algae to grow in.
- Air Flow Control. Keep in mind that airflow should be directed down the slope to prevent debris from getting under the gaps of your shingles.
