What Is Metal Roof Transition Flashing?
Metal Roof Transition Flashing prevents leakage at the point where two different roof pitches meet. Flatter transitions require more flashing on lower side.

Even after storm damage, flashing continues to protect the transition and prevent water from going under metal.

Key Features
- Water & Wind – Keeps rain run-off above metal. Keeps wind-driven rain & snow out of sensitive areas.
- Considerations – Angle of transition determines technique & size. Valleys & Ridges require special flashing solutions.
- Maintenance – Over time, may need to be resealed. Check after heavy storms.
