Zinc Strip Installation

What This Service Involves

Once installed near the ridge, zinc strips release trace metal ions each time it rains, and in the Northwest that means near-continuous protection. As runoff carries these ions down the slope, it creates conditions moss and algae struggle to colonize, reducing future growth without repeated chemical treatments. This passive defense is well suited to the region, where roofs stay wet long enough for the strips to work almost year-round. Homeowners tired of scraping moss every season often add zinc strips as a lasting preventive measure.

Benefits

Provides ongoing moss resistance with each rainfall; Reduces the need for repeated cleanings; Works passively without electricity or upkeep; Blends discreetly along the roof ridge; Suits the constant moisture of Northwest roofs

Our Process

1) Inspect the roof and identify optimal strip placement; 2) Clean the ridge area where strips will attach; 3) Secure zinc strips beneath the ridge cap or along the peak; 4) Seal fasteners and confirm proper runoff coverage

What Affects the Cost

Length of ridge line to be covered; Roof pitch and design complexity; Quality and gauge of the zinc material; Roof height and access difficulty; Whether existing moss is removed first

Best Time of Year

Install zinc strips in summer after moss removal so the roof enters the rainy season with active protection in place.
