  • Maximum pitch angle: 45 degrees.

Flashing Installation Steps:

  1. Sill Flashing: Secure the bottom flashing piece with roofing nails and cover with shingles.

  2. Step Flashing: Install L-shaped flashing starting from the bottom, overlapping with each layer.

  3. Counterflashing: Fit over the step flashing to prevent water ingress.

  4. Saddle Flashing: Install at the top under shingles, securing with roofing nails.
