What Is an Inside Corner?
An inside corner is the inward angle where two roof edges meet and gutter runs change direction. Gutter sections need a fitted corner piece at this point to guide rainwater around the roofline. The piece must match the roof angle and connect tightly with both gutter runs to help prevent leaks.

- An inside corner isn’t the same as an outside corner.
How Inside Corner Works
Inside corner work starts at the point where two roof edges form an inward angle. A gutter installer checks the roofline and marks where each gutter run ends. The corner piece then joins the runs and guides water through the turn.

The corner needs a close fit at both seams. The installer cuts or positions the gutter sections so their edges meet the corner cleanly. Mitered corner pieces are often used for this change in direction. Sealant helps close the joints and limit water leaks.
The corner also works with the roof’s drainage path. The installer checks the gutter pitch on both sides so water moves toward the proper outlet. A poor fit can leave gaps, block water flow, or cause water to spill over the gutter edge.
From the AGM Gutters team
When we install seamless gutters, we check each inside corner against the roofline before securing the runs. We look for a clean fit, steady water flow, and sealed joints. Our team also checks nearby fascia for damage that could affect the corner connection.
Inside Corner in Practice: A Real-World Example
A home has two roof sections that meet at an inward angle above a porch. During seamless gutter installation, the gutter runs meet at that point with an inside corner piece that directs rainwater toward the downspout.
