Roof Moss Problem? Know How To Fix It

Posted on

Moss can be a problem that often occurs to roofs that are shaded and moist. That can easily happen if your home has a lot of trees that cover the roof during the day, or tall buildings that surround your home and block the sun. Roof moss has the potential to cause your roof to rot, which will lead to needing professional help for roof repair. Thankfully, you can clean roof moss by following these steps.

Gather Tools and Materials

You'll need the following items to get rid of roof moss:

  • Ladder

  • Hose

  • Rake

  • Putty knife

  • Tarps

  • Bucket

  • Bleach

  • Spray bottle

  • Scrub brush

  • Zinc tape

  • Roofing nails

  • Hammer

While this list may seem big, you may already have many items on this list located around your home.

Removing The Moss

Start by using your hose to get any moss wet that is currently growing on your roof. The water will help soften the miss so it is easy to remove. You can use your rake to gently pull off the moss and put it into your bucket. Moss that is hard to remove from the roof with the rake can be lifted up with your putty knife, which should not damage the shingles underneath. When finished, rinse off your roof with a hose to wash away the tiny fragments of moss that remain.

Removing Surface Stains

Chances are that the moss has left some stains behind on the shingles. You can clean the stains using a solution that is one part bleach and one part water. Put it into your spray bottle, and cover the roof stains with your cleaning solution. A bristle brush can be used to scrub the area and remove the stain. Just be sure to place some tarps over the shrubs below your roof where you are cleaning, since the bleach solution could harm any living plants below.

Installing Zinc Tape

Metal roof caps are one way to prevent moss from forming a on a roof, but you can achieve similar results on a budget with zinc tape. Install a strip of the zinc tape along the top of your roof, securing it in place with roofing nails. Water will wash over the zinc tape when it rains, spreading enough zinc over your roof to kill moss before it forms.

If you've ignored moss and it has caused your roof to rot, you'll need to hire a local roof cleaning company to make the necessary repairs for you.
