There are many kinds of gutters available

Vinyl – easy to install but require many seams and become brittle over time.

Seamless Aluminum – seamless aluminum gutters are custom-made on site. These are the most popular gutters, and they only have seams at the corners. Slightly higher upfront cost but less seams mean fewer leaks and less maintenance over time.

Copper gutters – won’t mold, mildew or rust. They require welding at seams. Copper ionizes and changes color over time. They are also 2x+ the cost of aluminum gutters. Usually installed in conjunction with copper roofs Steel
