Zinc Gutters and Downspouts have proven to be a durable, long lasting material for any gutter system.
Over time, zinc gutters and downspouts form a protective zinc carbonate layer, (which is patina). The patina, which develops as a result of weathering, lends zinc gutter products their anti-corrosive properties. This allows there to be little maintenance and cleaning to be done towards the gutter system. Zinc is one of the longest lasting metals used in gutters and roofing materials, even longer lasting than copper, often lasting 80-90 years.
