Rain Gutter Materials
Aluminum – By contrast, aluminum rain gutters will never rust, although they can corrode if they come in direct contact with metals such as steel, tin or copper. While not as durable as some other materials, they still typically last thirty years with proper maintenance. Their lack of durability, however, can be a problem if a branch falls on them or if a heavy ladder is placed on them, as this could cause them to become deformed and lose their shape. They are one of the most inexpensive types of rain gutters available, and they are easier to install than steel and copper gutters because the joints need no soldering. They are lightweight, making them easy to ship, and they are available in a variety of colors, often negating the need for them to be painted.
Stainless Steel – Just as strong as galvanized steel, yet completely rustproof, stainless steel gutters are considered ideal for regions that experience heavy amounts of rain or snow. As can be expected, they are more expensive than galvanized steel gutters.
Copper – Copper rain gutters are known for their durability as well as their good looks, although copper is one of the most expensive materials available for making rain gutters. Copper can also turn green over time, which some people find unappealing. They should last a very long time, however – longer than a person’s lifetime.
Galvanized Steel – Known for being inexpensive and highly durable, galvanized steel gutters are often coated with zinc to gain its anti-corrosive advantages. They must be painted a specific way, using the right paint, however, or the paint could easily peel off. Another disadvantages is that while they are rust-resistant, they are not rustproof and will eventually succumb to rust over time, typically within twenty-five to fifty years.
Cast Iron – often used with heritage properties, cast iron gutters are known for their strength and durability.
