Box and K style Gutters

The main differences between K-style gutters and box gutters lie in their design, appearance, and functionality:


  • K-Style Gutters: K-style gutters have a distinctive shape that resembles the letter “K” when viewed from the side. They have a flat bottom and two curved sides, resembling the crown molding on homes.
  • Box Gutters: Box gutters have a more enclosed, rectangular or square cross-section, forming a box-like shape. They often run along the inner edge between two roof slopes.

Mounting and Visibility:

  • K-Style Gutters: K-style gutters are typically mounted on the exterior edge of the roof. They are more visible from the ground as they extend along the roof’s edge.

Box Gutters: Box gutters are often integrated into the roof structure. They are less visible from the ground, providing a more discreet appearance.


  • K-Style Gutters: K-style gutters are known for their efficiency in handling moderate to heavy rainfall. They are available in various sizes to accommodate different water runoff needs.
  • Box Gutters: Box gutters often have a larger capacity for water runoff compared to K-style gutters. They are suitable for areas with higher rainfall or larger roof surfaces.

Aesthetics and Style:

  • K-Style Gutters: K-style gutters are popular for their decorative appearance and are commonly used in residential settings. They come in various materials and finishes to complement the architectural style of the home.
  • Box Gutters: Box gutters may have a more utilitarian appearance and are often used in commercial or industrial buildings. They may be concealed within the structure for a cleaner look.

Ultimately, the choice between K-style gutters and box gutters depends on factors such as the building’s design, aesthetic preferences, local climate, and the required capacity to handle water runoff. Each type has its advantages and is suitable for different applications.
