INSTALLATION GUIDELINES
MOSS CONTROL ZINC ROLL
#MB50
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 fungistat, 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.
#MB50
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.
CAUTION!
Working above grade is inherently dangerous, be sure that proper fall protection measures are in place.
When working with power tools and sheet metal, gloves and eye protection are absolutely required.
These basic installation guidelines are for use with typical or standard applications. It is always recommended to seek advice from a licensed professional, and to check with your local building inspector or building permit office for approvals and possible variations that may apply.
