Zinc strips are one of the most effective and low-maintenance moss prevention tools available for Surrey, BC homeowners. Installed at the ridge of the roof, zinc strips release zinc oxide with every rainfall — creating a zone of moss-inhibiting chemistry that runs down the slope and prevents biological growth from taking hold. This guide covers zinc strip types, installation cost, and how they compare to other moss prevention methods in Surrey’s high-rainfall climate.

How Zinc Strips Work on Surrey Roofs
When rain falls on a zinc strip installed at the ridge, it carries zinc oxide particles down the slope with the water flow. This zinc-rich water prevents moss and algae from taking root in the shingle granules. The inhibition zone typically extends 12–18 feet downslope from the strip in Surrey’s rainfall conditions.
Key limitations to understand:
- Coverage is distance-dependent — a single ridge strip on a 30-ft slope may not protect the lower 12 ft of the roof effectively. For long slopes, additional strips at mid-roof are sometimes added.
- Zinc strips prevent new growth, not existing moss — if your roof already has active moss, treat and remove the moss first, then install zinc strips as a preventive measure going forward.
- Not a permanent solution — zinc strips gradually weather and lose effectiveness over 8–15 years depending on strip thickness and rainfall volume.
