Instructions / Assembly

Zinc is a 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 fungi-
stat, which then washes down the roof preventing destructive moss, algae and fungus growth.
Z-STOP
®
Zinc Roll is an ideal product for both the do-it-yourselfer and the professional roofer.
Apply Zinc Roll by butting it up against the ridge on both sides of all roof peaks. Rain water must run off the
ridge cap across the Zinc Roll and down the roof. Rain water must run over Zinc Roll to become effective. Apply
Zinc Roll below anything that blocks rain water flow such as chimneys, gables, and skylights.
Nail approximately every two feet with zinc coated or galvanized, neoprene washered roofing nails.
Note: On roofs with moss, algae, mildew or fungus, the existing growth must first be removed, by light pressure washing or brushing, then
the root systems must be treated and destroyed with a bleach solution. Install Z-Stop zinc strips to keep it from growing back.
