Read on to discover the very best steps to take for keeping your roof looking fresh!

Step 1: Make Sure You Stay Safe 🛑

Look, before you even think about climbing up onto your roof, you’ve got to prioritize your safety. Roof cleaning can be a risky endeavor, so here’s what you need to do:

  • Wear appropriate safety gear: Invest in a good pair of slip-resistant shoes or boots, safety glasses, and a harness if your roof has a steep pitch. 
  • Check the weather forecast: Cleaning a roof in wet or windy conditions is a big no-no. Wait for a dry, calm day to ensure your safety when you clean your roof.
  • Notify someone: Let a family member or neighbor know about your plan. Having someone aware of your actions can be a lifesaver in case of an emergency.

Step 2: Gather The Right Supplies 🔧

Now that you’re geared up and ready, it’s time to assemble your cleaning arsenal. Here’s what you’ll need:

  • Roof-safe cleaner: Choose a biodegradable, non-toxic roof cleaner specifically designed for your roofing material. 
  • Soft bristle brush or broom: This will help you scrub away dirt, moss, and algae without damaging your roof.  
  • Garden hose with a spray nozzle: You’ll use this to rinse off the cleaner and debris. 
  • Bucket and detergent: For mixing a soapy solution if needed.
  • Rubber gloves: Protect your hands from harsh chemicals.
  • Ladder: Ensure it’s stable and positioned securely on level ground.

Step 3: Sweep Debris Off Your Roof 🧹

Start by clearing your roof of loose debris like leaves, branches, and twigs. Use the broom or brush to gently sweep the surface. Make sure your gutters are clear too, as any clogs can lead to water damage down the road. Yes, the gutters – those often overlooked troughs that run along the edge of your roof. They can be sneaky troublemakers. If they’re clogged with debris, rainwater can’t flow smoothly, and that’s a recipe for potential water damage down the road. Nobody wants that surprise rainy-day waterfall inside their home, right? So, grab a ladder, and if you’re comfortable doing so, carefully check and clear out your gutters.

Step 4: Mix and Apply Cleaner 🧼

Follow the manufacturer’s instructions on the roof cleaner label to mix the solution correctly. Some cleaners may require dilution, while others can be used as-is. Be sure to wear your rubber gloves during this step. Use your bucket and a soft brush to apply the cleaner evenly across the entire roof surface.

Pro tip! Start from the bottom and work your way up to prevent streaking.

Step 5: Let The Cleaner Soak 🪣

After applying the cleaner, give it some time to work its magic. Check the instructions on the label for recommended soaking times. Typically, you’ll want to wait around 15-30 minutes. This allows the cleaner to break down dirt, algae, and moss.

During this time, stay off the roof to ensure your safety and avoid disturbing the cleaning process.

Step 6: Gentle Scrubbing and Rinsing 🧽

Now comes the fun part – roof washing! Use your soft bristle brush or broom to gently scrub the roof surface, giving it a soft wash in a circular motion. Be careful not to apply too much pressure, as you don’t want to damage your roofing material.

Next, grab your garden hose with a spray nozzle and rinse off the cleaner and debris. Start from the top and work your way down, ensuring you thoroughly rinse away all traces of the cleaning solution.

Step 7: Don’t Stop After The 1st Clean–Prevent Future Buildup 🫡

Congratulations, your roof is now squeaky clean! But, to keep it looking that way, consider taking some preventative measures:

  • Trim overhanging branches: Cutting back trees near your roof can prevent leaves and moss from accumulating. 
  • Install zinc or copper strips: These can help inhibit the growth of algae and moss over time. 
  • Regular inspections: Make it a habit to inspect your roof periodically and address any issues promptly to prevent buildup.

By following these seven steps for cleaning roofs, you’ll not only have a sparkling clean roof but also one that’s set to stand the test of time. Remember, safety should always be your top priority when working on your roof, so don’t rush through the steps and take your time.
