What Is a Mitered Corner?
A Mitered Corner is a shaped gutter section that joins two gutter runs at a roof corner. The section follows the corner’s angle and directs rainwater around the building. A sealed joint helps keep water inside the gutter. Mitered corners are common on homes with outside roof corners.

Key Takeaways About Mitered Corner
- It joins gutter runs at an outside roof corner.
- The joint must match the roof angle.
- It isn't the same as an inside corner.
How Mitered Corner Works

A Mitered Corner connects two gutter sections where roof edges meet at an outside angle. The gutter pieces are cut to fit the corner. Their edges meet to form a continuous path for rainwater.

The corner is secured to the gutter system and sealed at the joint. The seal helps stop water from escaping through the connection. The corner must line up with the roof edge and the gutter pitch, which is the slight slope that moves water toward an outlet.
How We Use It
During seamless gutter installation, AGM Gutters checks the corner shape before fitting the section. A home with several roof angles may need more than one mitered corner. An inside roof corner uses a different part and should not be confused with this one.

From the AGM Gutters team
When we install a mitered corner, we check the roof angle and gutter line before sealing the joint. Our team also checks that the gutter pitch carries water toward the outlet. A clean fit helps reduce leaks at the corner.
Mitered Corner in Practice: A Real-World Example
A home has an outside roof corner where two eaves meet. During seamless gutter installation, a mitered corner joins the gutter runs and carries rainwater toward the downspout.
