01 / FIELD NOTE

The before photo is the corner from below.

The before photo looks up at the inside corner. Green and white staining runs along the seam and down the gutter face. Old sealant at the joint is cracked and has pulled away from the metal. Brown perforated soffit surrounds the corner. The photo does not show an address or how long the seam had been leaking.

02 / FIELD NOTE

The after photo is the same corner, clean at the seam.

The after photo shows the same corner with a clean seam. The gutter face is an even brown, and the green and white staining on the metal is gone. Blue sky shows past the soffit. That brown is touch-up paint on the gutter, matched to the color already there. The soffit was already brown. PrimeFlow did not paint the soffit, the wall, or the house, and it does not offer house painting or stucco.

03 / FIELD NOTE

Why an inside corner can leak.

A seamless gutter is formed as a long run, so the straight length is one piece. An inside corner is still a joint: two pieces meet at a miter and are sealed so water stays in the trough. When that seal no longer bridges the seam, water can leave at the corner. Dried sealant, a little movement, or water sitting in the corner are ordinary reasons a crew finds a drip there. A photo cannot say which of those happened here. Building America treats the gutter and the downspout as one roof-runoff plan. One leaking corner is a break at that joint, not proof the rest of the system has failed.

04 / FIELD NOTE

Signs worth a look from the ground.

None of these proves the cause. They are a reason to have the corner checked, not a reason to worry about the whole roof. Stay on the ground. Do not climb to inspect a stain.

  1. Staining on the gutter face under a corner, including green or white marks like the before photo.
  2. Sealant along the seam that is cracked, missing, or pulled back from the metal.
  3. A drip at that corner during rain, while the rest of the run looks quiet.
  4. A stretch of the gutter face whose color no longer matches the rest of the run.
05 / FIELD NOTE

What this repair included.

The crew resealed the inside corner and applied touch-up paint on the gutter so the brown matches the existing color. PrimeFlow installers don’t play when it comes to installation. On this small corner, that meant the seam was resealed and the gutter face was brought back to the brown already on the metal.

What to do if a corner looks like this.
