  1. Scrub the roof with a brush

    Brush the moss away using a bristled brush. Begin at the peak of the roof and use downward strokes, taking care to avoid brushing off the granules that coat the shingles.

  2. Cover nearby plants with plastic sheeting

    Cover any plants under the roof with plastic sheeting before washing the roof with the bleach solution. If plastic sheeting isn't available, spray the plants with a garden hose before treating the roof with oxygen bleach.

  3. Wash the roof with a bleach solution

    Mix 2 cups of oxygen cleaner and 1/2 cup liquid dish detergent in a gallon of water. Stir vigorously to completely dissolve the oxygen bleach, and use a garden sprayer to apply the solution to the shingles. Allow the mixture to remain on the roof for 20 minutes.

  4. Rinse the oxygen bleach off the roof

    Use a garden hose to rinse the oxygen bleach solution off the shingles and any nearby plants.
