What happens here

When installing shingles adjacent to a vertical wall, 'Step Flashing' is crucial. Position a piece of 'Step Flashing' over the top edge of a shingle, ensuring it extends up the vertical wall. Then, install the next shingle over the 'Step Flashing'. When you nail this shingle down, the nail will also pass through and secure the 'Step Flashing' underneath. This process is repeated incrementally up the roof, creating a weather-tight seal. The vertical portion of the 'Step Flashing' will eventually be covered by siding or another piece of cap flashing.

Goal: Waterproof roof-to-wall intersections.

Tools and materials

  • Hammer — Driving nails
  • Nails — Securing both the shingles and the step flashing
  • Shingles — The shingle courses being installed concurrently with the flashing
  • Step Flashing — Waterproofing roof-to-wall intersections by layering with shingles

What they say

Shingles get installed with galvanized nails. They come in coils for guns like this or you can buy hand nails like this. As we work up the roof, we need to add step flashing. Step flashing gets installed as you install your shingles. Install your shingle on top of that. When you nail down your shingle, it'll also go through the flashing. This process continues as you go up the roof. Either your siding will sit over the top or another piece of flashing will go over top of that. When your starter strip gets nailed low here and this tar adheres to the shingles, it holds these
