Algae and fungus must have three nutrients to grow which include:

• Heat
• Moisture
• Organic matter

Moisture Increases Roof Algae and Fungus Growth 

Rain and moisture, even morning dew, can increase roof algae and fungus growth. The professionals at ROOF REAL CLEAN have found that it can be as little as 12 to 16 months for algae and fungus spores to germinate, providing that debris such as leaves, etc. are not allowed to remain on the surface. Increased periods of rain can also have an effect on increased roof algae and fungus growth. 

Hotter Weather Promotes Roof Algae and Fungus Growth

Another factor that can contribute to increased roof algae and fungus growth is hotter weather conditions, which increase attic temperatures. Increased surface temperatures create moisture when the sun goes down, which promotes fungus and algae growth.  Roofs in sub-tropical climates will also show signs of fungus and algae growth much quicker than roofs in northern climates.

Quality of Roofing Material

Quality of roofing material can also affect roof algae and fungus growth. Typically, A roof that is 15 – 25 years old will show signs of algae and fungus growth quicker than a 30 or 40 year old roof due to:

• Thickness of the material used
• Amount of copper granules applied
• Amount of ceramic granules applied
