Do aluminum or copper half-round gutters last longer?

In order to understand why some people choose copper half round gutters over aluminum, it is necessary to understand the key differences between them. Copper gutters are more durable than aluminum, and that is why there is a premium to pay when having copper gutters installed. Aluminum gutters tend to dent, tear and develop holes, within the span of a few years. Copper gutters last significantly longer than aluminum gutters, thanks to the material used to make them, and the craftsmanship necessary to create copper gutters. As a general rule, copper half-round gutters last much longer than aluminum half-rounds.
