Roof Cleaning With Bleach


When cleaning the exterior of their homes, many people often forget to clean their roofs. Your roof offers the perfect growing environment for unwanted guests such as mold, mildew and moss, which can damage your roof. The deterioration can lead to costly repairs. Fortunately, you can give your roof a thorough cleaning with bleach, which also removes damaging fungus.

Things You'll Need

  • Plastic tarps
  • Rubber gloves
  • Bucket
  • Bleach
  • Ladder
  • Water hose
  • Brush broom
  • Protect plants around your home's foundation by covering them with tarps. Bleach can harm plants and no matter how hard you try, some bleach is bound to fall from the roof. Using a tarp to cover the plants will protect them from damage.

  • Wear rubber gloves when working with bleach, a skin irritant that can cause redness and blisters.

  • Fill a bucket with equal parts of bleach and water. Place the bucket outside your home, next to the ladder. Gain access to your roof by climbing the ladder. Make sure to have a friend or family member steady the ladder while you are on it. Once on your roof, let the other person hand you the cleaning tools and bucket filled with the mixture.

  • Remove the surface debris such as leaves, moss, mold and twigs from the roof, using a water hose.

  • Saturate a brush broom into the mixture and scrub the roof vigorously. Continue saturating the broom and scrubbing until you have thoroughly cleaned the roof. Allow the bleach mixture to sit for 15 minutes, then rinse the roof clean with the water hose.

Tips & Warnings

  • Bleach can damage asphalt roofs.
  • Use fungicide instead of the bleach-water mixture for asphalt roofs.
  • Never mix bleach with ammonia or products containing ammonia, as the resulting fumes are toxic.
