Copper guttering has long been considered the ultimate in guttering and for good reason. There are several reasons to use copper gutters on a home, beyond the aesthetic and elegant look it adds. Copper is very corrosion-resistant, so it requires the least amount of maintenance, and will endure even in salty conditions and areas with a great deal of acid rain. It is not uncommon for copper gutters to have a lifespan of 60 to 90 years or triple that of aluminum. Copper gutters and copper roofline products are versatile, durable, attractive and look great on traditional properties, plus they offer a wide range of advantages that are well worth the outlay – including rust resistance and minimal upkeep requirements.
The beauty of copper is that its colour changes over time, developing a patina that provides protection against corrosion – and also acts as an algaecide and fungicide, so it keeps growths, such as moss and lichen, to a minimum and ensures gutters stay clear. In a normal environment, copper will turn from a shiny new penny look to dark brown within the first year. Over the next 30-75 years, copper will turn from a streaky green to a darker greenish colour and eventually to a blue-green colour.
