Winter can take a toll on your roof, leaving behind debris, moss, algae, and even structural damage. Proper post-winter roof cleaning not only improves curb appeal but also extends the lifespan of your roofing materials. Follow these step-by-step guidelines to safely and effectively clean your roof and restore its original look.

What Is the correct way to clean a roof?

Cleaning a roof requires careful planning and the right techniques to avoid damage. Harsh chemicals or improper pressure washing can cause more harm than good. Here’s how to clean your roof properly:

Step 1: Inspect your roof for winter damage

Before cleaning, conduct a thorough inspection:
✔ Look for missing or damaged shingles.
✔ Check for moss, mold, or algae growth.
✔ Examine gutters and downspouts for blockages.
✔ Identify any water stains or leaks inside your home.

If there’s serious damage, consult Masterpiece Roofing for professional repairs before proceeding with cleaning.

Step 2: Remove loose debris

Using a roof rake, soft-bristle broom, or leaf blower, remove leaves, twigs, and other debris. Start from the top and work downward to prevent damage to the shingles.

✔ Avoid using metal tools that can scratch or loosen shingles.
✔ If using a blower, keep the pressure low to moderate.

Step 3: Unclog gutters and downspouts

Clogged gutters can cause water buildup, leading to leaks and damage.
✔ Scoop out debris with a gloved hand or gutter scoop.
✔ Flush the gutters with a garden hose to ensure proper drainage.
✔ Inspect for loose fasteners or sagging sections that may need repairs.

Step 4: Apply a gentle cleaning solution

If your roof has moss, algae, or stains, mix a cleaning solution:
✔ 1 part bleach or vinegar + 3 parts water (avoid harsh chemicals).
✔ Apply with a pump sprayer and let it sit for 15-20 minutes.
✔ DO NOT scrub or power wash—this can damage shingles.

Step 5: Rinse the roof with low-pressure water

Use a garden hose with a spray nozzle to rinse the roof. Avoid high-pressure washing, which can strip away protective granules on asphalt shingles.

✔ Start at the top of the roof and work downward.
✔ Ensure all cleaning solution is fully rinsed off.

Step 6: Remove any remaining moss or algae

For stubborn moss or algae:
✔ Use a soft brush or sponge to gently remove patches.
✔ Avoid scraping or aggressive scrubbing, which can weaken shingles.

To prevent future growth, consider installing zinc or copper strips along the roof ridge.

Step 7: Perform a final inspection

After cleaning, inspect the roof again for:
✔ Any remaining stains or debris.
✔ Signs of loose or missing shingles.
✔ Potential gutter or drainage issues.

If you notice damage, schedule professional repairs with Masterpiece Roofing to prevent costly future issues.
