What's Z-STOP?

Introducing Z-STOP

Z-STOP is a zinc moss, algae and fungus inhibitor that is applied in strips to old or new roofs. It works with any wood, flat tile, metal or composition roof. The natural action of rain water time-releases zinc carbonate, a proven fungistat, which then washes down the roof preventing destructive moss, algae and fungus growth. Z-STOP is an ideal product for both the do-it-yourselfer and the professional roofer.

A new roof is one of the largest single home maintenance expenses you will face. If you're putting on a new roof you will want to make it last as long as possible. If you have an old roof, you will want to put off repairs as long as possible. Z-STOP can help you do both. Z-STOP goes a long way to greatly increase the life of your roof - old or new!

Don't Let Moss, Algae or Fungus Destroy Your Roof!

  • Moss and fungus penetrate roof surface and weaken fibers.
  • Heavy build-up can lift shingles. Both lead to shortened roof life
  • Red, white or black patches discolor roof. Black color on your cedar shingles is not "weathering" but roof algae breaking down wood fiber.
  • Note how zinc washed down from galvanized pipe has kept moss, algae and fungus from growing.
