Why Does the Moss on My Roof Keep Coming Back?

October 31, 2019 by ROTban Services Corp. A roof covered in moss.

If you have moss on your roof, and the moss keeps coming back after you remove it, then this article is for you.

The moss on your roof keeps coming back for a few reasons:

  1. The conditions on your roof are ideal.
    Moss flourishes where the climate is mild, shady, and damp. And the Pacific Northwest is known for its mild, oceanic, damp climate. Moss does need some sun for photosynthesis, but it prefers sun that is shaded like from an overcast sky. Does that sound familiar?
  2. Nothing disturbs the moss on the roof.
    There is no foot traffic on your roof, so there’s nothing to disturb the growth of moss.
  3. Moss has rhizoids.
    Moss doesn’t have true roots because it’s not a vascular plant. But moss does have rhizoids, which are thin, thread-like structures that anchor the plant in place just like roots would.

So, when you remove moss, if you don’t remove all the rhizoids at the same time, then the moss will quickly grow back. In addition, spores are everywhere in the environment. They land on everything and grow wherever the conditions are right.

In order to have success removing moss and keeping it away, you must deal with the rhizoids and the spores, sterilizing them. But even after that, you have to keep sterilizing the spores. That’s where you really need repeat-action sterilization.
