Expert Verdict Reviewed by the SuperArbor Pro Desk

Match the miter finish to the gutter color and order inside and outside miters together once the gutter layout is laid out. Lap the miter over the gutter ends and fasten plus seal the joint to prevent corner leaks, the most common failure point on strip-mitered systems. For heavy-exposure corners, consider a box or custom miter instead.

Use ladder safety practices and wear gloves when handling and fastening metal gutter miters.
