- 1). Put on long clothing, rubber gloves, safety glasses and slip-resistant shoes for protection.
- 2). Spray water from a garden hose onto the vegetation below the roof. Cover the vegetation with plastic sheets to protect them from bleach runoff.
- 3). Fill a 3-gallon plastic bucket with 1 gallon of chlorine bleach and 1 gallon of water. Thoroughly mix the solution with a stir stick. Pour the solution into a pump garden sprayer.
- 4). Spray the bleach solution onto the mossy shingles. Be careful while walking on the roof. Allow the solution to soak into the moss for 30 minutes.
- 5). Brush the moss off the shingles and roof using a long-handled scrub brush. Scrub down the roof to prevent the shingles from lifting or breaking off.
- 6). Rinse the shingles with water from the garden hose. Spray down the roof to prevent water from becoming trapped underneath the shingles. Thoroughly rinse the shingles.
- 7). Allow the roof to air-dry. Repeat the cleaning process if any moss remains on the shingles.
