Ingredients

  • 1 gallon of water (preferably warm to help dissolve other ingredients)
  • 1 cup of bleach (standard household bleach, not scented)
  • 1/2 cup of trisodium phosphate (TSP) – available at hardware stores, helps remove tough stains and algae
  • 1/4 cup of liquid dish soap (non-phosphate, biodegradable preferred)
  • Protective gloves and eyewear (to ensure safety during mixing and application)

Equipment

  • Garden sprayer or pump sprayer (to apply the solution evenly on the roof)
  • Soft-bristle brush or broom (for gentle scrubbing if needed)
  • Ladder (ensure it is stable and safely positioned)
  • Protective clothing (long sleeves, pants, gloves, and safety goggles)
  • Hose with spray nozzle (for rinsing the roof after cleaning)

Instructions

  1. Prepare your safety gear. Before mixing or applying the solution, make sure you are wearing gloves, protective eyewear, and clothing to avoid any contact with bleach and TSP.
  2. Mix the solution. In a large bucket, combine 1 gallon of warm water with 1 cup of household bleach. Slowly stir in 1/2 cup of trisodium phosphate and 1/4 cup of liquid dish soap. Mix gently until all ingredients are fully dissolved.
  3. Fill the garden sprayer. Pour the mixed solution into your garden or pump sprayer. Make sure the sprayer is clean and functioning properly to ensure even application.
  4. Apply the solution. From the ground or using a ladder, spray the solution evenly across the roof surface, focusing on areas with visible moss, algae, or stains. Avoid spraying on windy days to prevent overspray on plants or yourself.
  5. Allow the solution to sit. Let the solution penetrate the roof surface for about 15-20 minutes. Do not let it dry completely; if it starts drying, lightly mist it with water.
  6. Scrub gently. For stubborn spots, use a soft-bristle brush or broom to gently scrub the affected areas. Avoid aggressive scrubbing to prevent damaging shingles.
  7. Rinse thoroughly. Use a garden hose with a spray nozzle to rinse off the cleaning solution thoroughly. Start from the top and work your way down to avoid water damage.
  8. Inspect and repeat if necessary. After the roof dries, check for any remaining stains or moss. Repeat the cleaning process for particularly stubborn areas.

Tips & Variations

Safety first: Always test a small, inconspicuous area of your roof before applying the full solution to ensure no discoloration occurs.

Alternative to bleach: If you prefer a bleach-free option, substitute the bleach with an equal amount of white vinegar. This will be gentler but may require multiple applications.

For eco-conscious users, you can mix 1 cup of baking soda with water and spray it onto the roof. Let it sit and scrub gently.

This method is less harsh and safe for surrounding plants.

When applying the solution, avoid spraying on plants and shrubs. Cover them with plastic sheets if necessary to protect from bleach runoff.
