Your roof protects your home, but different materials require different cleaning methods. Using the wrong technique can cause damage and shorten the lifespan of your roof. Whether you have asphalt shingles, metal, wood shakes, tile, or a flat roof, here’s how to keep it clean and in top condition.
1. Asphalt Shingles
Asphalt shingles are the most common roofing material, but they are sensitive to high-pressure washing.
Why Soft Washing Works Best
- Removes algae, moss, and black streaks without stripping granules.
- Extends the lifespan of your roof by preventing premature deterioration.
Cleaning Tips
- Use a soft wash method with a bleach-based cleaner to kill moss and algae at the root.
- Avoid high-pressure washing, which can damage the protective granules and shorten the roof’s lifespan.
- Schedule professional roof cleaning every 1–3 years depending on your climate.
2. Metal Roofs
Metal roofs are durable and require specific cleaning techniques to prevent damage.
Why Proper Cleaning is Critical
- Algae and mildew can make metal roofs dangerously slippery.
- Dirt buildup reduces the roof’s reflective properties, impacting energy efficiency.
Maintenance Tips
- Use non-abrasive cleaners and soft brushes to avoid scratching the surface.
- Rinse thoroughly to prevent streaks and chemical damage.
- Inspect seals and fasteners to ensure the roof remains watertight.
3. Wood Shake Roofs
Wood shake roofs add character but require careful cleaning to prevent rot.
Why Special Care is Needed
- Retains moisture, promoting moss, mold, and decay.
- High-pressure washing can splinter wood and remove protective oils.
Best Practices
- Use soft washing with eco-friendly cleaners to remove algae and moss without damaging the wood.
- Keep branches trimmed to prevent debris accumulation.
- Apply a wood preservative after cleaning to extend the roof’s lifespan.
4. Tile Roofs
Clay and concrete tiles are durable but prone to cracking under pressure.
Key Considerations
- Algae and moss can weaken tiles and deteriorate grout.
- Walking on tile roofs can easily cause cracks.
Cleaning Tips
- Use soft washing or low-pressure washing with biodegradable cleaners.
- Inspect tiles for cracks during cleaning and repair them promptly.
- Avoid stepping directly on tiles—use safety walkways if necessary.
5. Flat Roofs
Flat roofs collect debris easily, leading to drainage issues.
Why Maintenance Matters
- Standing water accelerates mold and algae growth.
- Clogged drains cause water pooling and potential leaks.
Steps to Keep Flat Roofs Clean
- Remove debris manually or with a leaf blower before washing.
- Use a low-pressure rinse to avoid damaging the membrane.
- Inspect and maintain drainage systems to prevent pooling water.
