How to Clean Roof Shingles Like a Professional

Your roof shingles protect your home from the elements, but they might also collect dirt, algae, and moss. As a result, your roof may look old and worn out.

Why Cleaning Roof Shingles Is Important

Clean shingles aren’t just about looks. Dirty shingles can cause real problems for your home. Algae and moss hold moisture against your roof, which can lead to rot and expensive repairs. Dark stains also make your roof absorb more heat, meaning higher cooling expenses in the summer. Cleaning your roof shingles solves each of these problems.

Plus, a clean roof boosts your home’s value. Clean shingles can add thousands to your asking price if you’re considering selling. But even if you’re staying put, you’ll love how fresh your home looks with clean shingles.

Recognizing When to Clean Your Roof Shingles

How do you know when it’s time to clean roof shingles? Look for these signs:

  • Black or green streaks running down your roof
  • Fuzzy moss growing on shingles
  • Shingles that look darker than they should
  • White or gray chalky residue

Best Ways to Clean Roof Shingles

  • Safety First – Start by putting on your safety gear and ensuring your ladder is stable. Never clean your roof alone. Have someone spot you from the ground.
  • Protect Your Plants – Cleaning solutions can harm vegetation, so cover plants and grass below with tarps.
  • Gentle Scrubbing – Use a soft brush to gently scrub tough stains. Scrubbing too hard could damage the shingle granules.
  • Rinse Thoroughly – Rinse with your garden hose from top to bottom. Make sure all the cleaning solution is gone.
