1. Start with coil stock
Use a knife and a straightedge to cut a 12-in. by 14-in. piece of flashing from the same metal used for the roof’s step flashing.
2. Make a 90° bend
Use a straightedge to make a bend that will leave 6 in. of flashing on the roof and 6 in. going up the wall.
3. Measure the first bend
Mark the flashing 6 in. from the end to locate the approximate location of the first fold.
4. Position seamers for the next bend
Hold the seamers at an angle slightly beyond 90° in relation to the first bend so the bottom of the flashing will drain. Keep the seamers away from the first bend or the metal might tear at the corner point.
5. Bend the flashing upward
As you push the seamers forward, the metal on the other side of the bend will follow, beginning to form the dam.
6. Fold the flashing like wrapping a present
Bend the leg that will abut the house at 90° and the roof leg a bit greater than 90° to encourage drainage.
7. Flatten the bends
Use a block (and, if needed, a hammer) to make the flashing smooth and crisp.
