Worried that algae, moss, mold or mildew is growing on your roof and leaving it open to more damage? Copper Cat strips are a simple, effective way to keep a roof clean and protect your investment.

How Copper Cat works

  • Copper and rain.As water runs over the copper, it releases ions that stop algae, mold, moss and mildew growing on the shingles.
  • Built to outlast.The double-sided copper strip is 20 times stronger than zinc strips, so it outlasts other roof cleaning systems.
  • It blends in.The copper oxidizes and blends with 90% of shingle colors for a neat, clean look.
  • New or existing roofs.The strips work on new or existing roofs of asphalt, cedar, slate and more.
  • Streaks gone.They improve the look of a roof by removing black streaks, patchy spots and other discoloration.

On Joe’s house

When we replaced Joe’s roof with Atlas StormMaster shingles to get rid of the black streaks on the old one, we installed Copper Cat in strategic places to stop moss and lichen coming back. See the project
