🏠🔍 BLACK STREAKS ON YOUR ROOF? DON'T ASSUME YOU NEED A NEW ONE!
Those dark streaks are often caused by algae — not necessarily a failing roof.
🌳 Shaded areas and our humid Kentuckiana weather can make roof staining more noticeable over time.
⚠️ One thing you SHOULD NOT do: blast asphalt shingles with a pressure washer.
High pressure can damage the roofing surface and disturb protective granules.
✅ Soft washing uses a much lower-pressure application and, when done with the correct process and roof-safe products, can help address organic staining without relying on aggressive pressure.
💡 HOMEOWNER TIP: If your roof has black streaks but otherwise looks intact, it may be a cleaning issue. If you also see curling shingles, missing shingles, heavy granule loss, or leaks, have the roof evaluated before deciding what to do.
🔨 At Indiana Roof & Home, we believe in helping homeowners understand the difference between a cosmetic issue and actual roof damage.
