Step flashing is a rectangular piece of flashing bent 90 degrees in the center.
The base flashing or apron flashing is the bottom piece.
It is used for roof to wall flashing.
It is a solid sheet that is pre formed to fit under the shingles and over the gutter underneath the roof line.
Gutter aprons take on an additional role by hanging down an inch or so into the back of the gutter to prevent water from dripping or splashing behind the gutter.
The gutter flashing comes in various widths and 12 foot lengths.
Placed opposite to base flashing or above base flashing counter flashing completes the two part team.
