Why Does Moss Grow On Rooftops?


Moss on your roof is a common problem for homeowners. At first glance, it may seem like a harmless problem, but it can cause a lot of damage to your roof. Moss will continue to grow as it absorbs water and expands. This expansion can crack and break your shingles, leading to leaks in your roof and potentially dry rot in your home. Dry rot can weaken the structure of your home. Why, then, does this occur? Why does moss grow on roofs?

Leaves, dirt, and other organic matter collect on your roof over time. In addition, shade on your roof from tree limbs creates a wet environment out of direct sunlight. The organic matter supplies essential nutrients to the moss while the humidity fosters a moist environment for the moss to grow.

Protecting against moss growth on your roof can be done. Keep overhanging tree limbs trimmed up so your roof is exposed to direct sunlight and can dry out after it rains. Additionally, keep your roof free of leaves, dirt, and other debris.
