Moss growing on a roof

How to Remove Moss (and Keep It from Growing Back)

When you think of the cute and quaint homes from fairytales, you’re probably picturing ivy-covered walls with moss-speckled rooftops. They have such a charming feel to them and blend seamlessly into their surrounding nature, but all of that greenery growing on your home can lead to some serious damage down the road.

Will Moss Damage My Roof?

Moss thrives in damp and shaded areas, so if your home is covered by the shade of a tree, then you’re more likely to encounter a moss problem at some point. Its destructive nature comes in the form of its roots. Like all plants, moss plants its roots wherever it’s growing, these roots either find their way into cracks of roof shingles, or in the gaps between shingles, and the constant moisture can lead to bacteria and mold growth!

Additionally, it’s dangerous to work on a moss-covered roof, because moss is typically pretty slippery to walk across.

How Can I Remove Moss for Good?

Like we said earlier since moss is slippery to walk on, you should try to remove most of the moss from the safety of your ladder. Here are the best ways to eliminate moss from your roof, and the order in which to try them:

  1. Hose down your roof with a garden hose (a pressure washer could damage your roof even more). Then take a broom or long-handled brush and scrape the remaining moss off of your roof. Rinse again with the garden hose.

  2. Apply a store-bought cleaning solution - avoid bleach, its corrosive nature could ruin your roof.

  3. To prevent future moss growth, install zinc strips on your roof. Nail zinc strips to the peaks of your roof so that when it rains, zinc runs down your roof and inhibits moss growth.
