Why Roof Cleaning Matters

Before we dive into the nitty-gritty, let’s talk about why cleaning your roof is so darn important.

  • Prolonged Lifespan: A clean roof lasts longer. Removing moss, algae, and debris helps prevent premature wear and tear.
  • Energy Efficiency: A clean roof reflects heat better, keeping your home cooler and potentially reducing your energy bills.
  • Curb Appeal: An immaculate roof boosts your home’s appearance and can even increase its resale value.

Materials and Tools You’ll Need 🧰

To get started, gather these materials and tools:

  • Safety Gear: Safety first! Grab a sturdy ladder, non-slip shoes, and safety goggles.
  • Garden Hose: You’ll need it for rinsing.
  • Broom or Leaf Blower: For removing loose debris.
  • Moss Killer or Algae Remover: Choose the right one for your specific issue.
  • Soft Bristle Brush or Scrubbing Broom: For gentle scrubbing.
  • Bucket: To mix your cleaning solution.
  • Roof Cleaning Solution: You can buy a commercial one or make your own (we’ll get to that).
  • Protective Tarps or Plastic Sheeting: To cover plants and protect them from runoff.
  • Safety Ropes or Harnesses (optional): If your roof has a steep pitch, consider extra safety measures.

Ensure Your Safety


Before you start climbing around on your roof, make sure you’re taking safety seriously. Here are some tips:

  • Use a stable ladder: Make sure it’s on solid ground and extend it at least three feet beyond the roof’s edge.
  • Wear non-slip shoes: A good grip is essential when you’re up there.
  • Watch the weather: Don’t clean your roof in the rain or when it’s wet; it’s a slipping hazard.
  • Let someone know: Tell a family member or neighbor what you’re doing, just in case.

The Roof Cleaning Process in 10 Steps

Now, let’s get down to business. Here’s how to clean your roof step by step:

1. Safety First – Gearing Up

Before you ascend to your roof, make sure you’re wearing all the necessary safety gear, including non-slip shoes, safety goggles, and gloves. Safety should always come first. So if you feel hesitant to get up on your roof, know that you should always rely on professional roof cleaners.

2. Remove Loose Debris – Broom or Blower

Start by using a broom or leaf blower to remove any loose debris, like leaves, twigs, and branches, from your roof’s surface. This step prevents debris from clogging your gutters and downspouts. Plus, it makes the next steps more effective.

3. Protect Your Plants – Tarps or Plastic Sheeting

Cover any nearby plants or landscaping with protective tarps or plastic sheeting. This will prevent them from getting damaged by runoff or cleaning solutions. Your garden will thank you later!

4. Mix Your Cleaning Solution – Homemade or Store-Bought

You have two options here:

  • Homemade Solution: Mix equal parts of water and white vinegar or hydrogen peroxide. Add a dash of dish soap.
  • Store-Bought Solution: Purchase a commercial roof cleaning product. Be sure to follow the manufacturer’s instructions.

5. Apply the Cleaning Solution – Gentle Scrubbing

Using a soft bristle brush or scrubbing broom, apply the cleaning solution to your roofing materials. Gently scrub the affected areas where you see moss, algae, or stains.

⭐ Bonus Tip! Work from the top of the roof down to ensure that the cleaning solution runs off properly.

6. Wait and Let It Soak – Patience Pays Off

After applying the cleaning solution, let it sit for about 15 to 20 minutes. This gives it time to break down and loosen the moss, algae, and stains. While you wait, enjoy a cup of coffee or admire your garden.

7. Rinse Thoroughly – Garden Hose Power


Once the cleaning solution has had time to work its magic, it’s time to rinse it off. Use a garden hose with a spray nozzle to rinse your roof thoroughly. Start at the top and work your way down, making sure to remove all the cleaning solution and debris.

8. Prevent Future Growth – Zinc Strips (optional)

Once you’ve finished your DIY roof cleaning, you’ll want to discourage moss and algae from returning. So consider installing zinc strips near the ridge of your roof. Rainwater washes zinc particles down the roof, preventing the growth of these unwanted visitors.

9. Check for Damage – Roof Inspection

While you’re up there, take the opportunity to inspect your roof for any damage. Look for loose or damaged shingles, worn flashing, or any other issues that may need attention with a roof repair.

10. Gutters and Downspouts – Don’t Forget Them!

Lastly, don’t neglect your gutters and downspouts. Ensure they’re clear of any debris and clean them if necessary. Proper drainage is crucial to prevent water damage to your home.

Homemade Roof Cleaning Solution Recipe

If you prefer the DIY route, here’s a simple recipe for a homemade roof cleaning solution:


  • 1 gallon of water
  • 1 gallon of white vinegar
  • 1/4 cup of dish soap


  • Mix all the ingredients in a large bucket.
  • Stir well to ensure they are thoroughly combined.
  • Use this mixture as your cleaning solution, following the steps outlined above.

Safety Ropes or Harnesses (optional) 🧗‍♂️

If your roof has a steep pitch or if you’re not entirely comfortable working at heights, consider using safety ropes or harnesses to clean your roof shingles. These can provide an extra layer of protection and peace of mind.

Aftercare Tips

Congratulations! You’ve successfully cleaned your roof. Here are some aftercare tips to ensure it stays in tip-top shape:

  • Schedule regular roof inspections to catch and address issues early.
  • Keep your gutters clean to prevent debris buildup and water damage. You can DIY this or hire a professional roof cleaning service.
  • Trim overhanging tree branches to prevent leaves and twigs from accumulating on your roof.
  • Consider installing zinc strips to discourage future moss and algae growth.
  • Repeat the cleaning process every few years, or as needed, to maintain a clean and healthy roof.
