Buying Guide: Zinc Strips For Roof Moss Control
- Roof type compatibility: Zinc strips work with metal, tile, and shingle roofs. Confirm your roof material before purchasing.
- Coverage and climate: In shaded, moisture-prone areas, you may need longer runs or multiple strips to maintain moss-free surfaces.
- Material purity: Look for 99.9% zinc for better corrosion resistance and longer life, as seen in the products above.
- Installation method: Most strips require removal of backing, placement under the shingles’ leading edge, and sealing at the edges to prevent wind lift. Have roofing sealant on hand if recommended by the product instructions.
- Maintenance: Zinc strips are preventive; they do not replace cleaning. Inspect after heavy rainfall or windy seasons and replace worn sections as needed.
- Safety: Use proper ladder safety and cutting tools. Some products may be easily cut with scissors or a utility knife as noted in the features.
- Cost considerations: Larger roofs benefit from longer rolls or multiple rolls for full coverage, so plan based on roof area and moss-prone zones.
