đĄ Roof Cleaning in Bethlehem, PA: Why Soft Washing Is the Right Choice
Think your roof is dirty because of age? It might actually just be algaeâand you donât need a new roof. You need a professional soft wash.
In Bethlehem, PA and the surrounding Lehigh Valley, homeowners often mistake those black streaks or green patches as wear and tear. But the truth is, itâs usually Gloeocapsa Magmaâa type of bacteria that feeds on your shingles.
â Why Roofs in Bethlehem Attract Algae and Moss
Our climate in eastern Pennsylvaniaâhumid summers, lots of rain, and plenty of tree coverâcreates the perfect breeding ground for:
- Black streaks (bacteria)
- Green moss
- Lichen patches
- Mildew and mold
This not only looks badâit traps moisture, deteriorates your roof, and shortens its lifespan.
đ§ Soft Washing: Safe, Effective, and Recommended by Shingle Manufacturers

Unlike pressure washing, soft washing:
- â Uses low-pressure water and special cleaning agents
- â Kills algae, moss, and lichen at the root
- â Keeps your shingle warranty valid
- â Wonât blast away granules or cause leaks
In fact, most major roofing manufacturers recommend soft washing for this exact reason.
đ§˝ Local Case Study: Roof Saved in Historic Bethlehem
