Seamless rain gutters are just as the name implies – they are seamless, meaning, there isn’t a break in the gutter. Since there is no seam, there are no leaks. This is why they are the most popular type of gutter today.
Rain gutters are usually made from aluminum, but they can be made from copper. They are made with a seamless gutter machine that is brought to your home by the gutter contractor. Each individual gutter is customized to fit your home.
The above video from KWM shows how rain gutters are manufactured using a gutter rolling machine. Gutter machines operate by taking a stock roll of gutter grade aluminum, which is pre-coated by a color of choice, and pull the aluminum through the length of the machine over a series of metal forming rollers to create the D-shape structure of the final product.
Seamless gutter machines allow the gutter installation professional to manufacturer gutters to a specific dimension on site at the home or business.
