Is there a type of gutter that can last 50 years or more?
Is there a gutter that requires very little maintenance and comes in a bunch of colors?
The answer is yes, and these gutters are made of cast iron.
Cast iron gutters come in a number of styles, from round to K-style.
BUT... they are not available in the US. :(
When I first heard of iron gutters I was sure there was some mistake. I know cannon balls are made of iron but not gutters. I couldn't imagined heavy lengths of iron hanging from wooden fascia boards. I imagined a small army would be needed to hang each length of iron gutter.
Then I did some heavy research. (Actually it was just a Google search)
Iron gutters are not as heavy as one would think, although at least two people are needed to install each 6 foot section.
Each length is secured to the house with powerful brackets and each gutter seam is bolted together with a rubber seal.
The downspouts fit together kinda like vacuum cleaner tubes. They are also secured to the house using strong brackets.
I am not sure why cast iron gutters are not available in the US. They are mainly used in Europe and all of the online suppliers are in the UK. Even in Europe these gutters are used mostly on old historic houses and buildings.
Cast iron gutters are an old world invention that are not used very much today. They are a throw-back from an earlier time when things were built to last.
