Why does moss grow on the roof?
Moss can grow on a roof for many reasons, but Most often, it is caused by moisture buildup and poor ventilation. In an article about moss Let's summarize well:
“The more water and debris there are, the greater the moss growth. Another critical factor is how much shade the roof receives. A very shady roof prevents moisture from evaporating and creates excellent conditions for moss growth.”
The roof's slope, poor drainage systems, and accumulation of organic matter also create favorable conditions for moss growth. If the roof does not receive enough sunlight and moisture evaporation is slow, moss spreads quickly.
