Things You'll Need
- 16-inch-wide roof flashing
- Measuring stick
- Marker
- Tin snips
- Needle-nose pliers
- 1-inch self-starting screws
- Hammer
- Awl
Instructions
Draw a trapezoid on the flashing. Draw the first side 24-1/4 inches long. Measure 8-1/2 inches from each end of this line and make a mark.
Measure 16 inches perpendicularly from the first line at each of the marks and make a second set of marks. Draw a 12-inch line between the second set of marks.
Draw a line from the right endpoint of the 12-inch line to the right endpoint of the 24-1/4-inch line. Draw a line from the left endpoint of the 12-inch line to the left endpoint of the 24-1/4-inch line. This is your trapezoid.
Cut the trapezoid out using the tin snips.
Roll the flashing into a cone, overlapping the edges by one inch. The narrow opening of the cone will be the short 12-inch side you drew, and the wide opening of the cone will be the 24-1/4-inch line.
Roll the top of the cone over to the outside by gently tapping with a hammer or bending with needle-nose pliers.
Attach the rolled-up cone to a 6-foot two-by-four, narrow opening down, 4 feet from the bottom. Place the overlapping seam line over the board and screw through both layers of metal in the 1-inch overlapping area and into the wooden board below, using a stubby Phillips screwdriver and 1-inch self-starting screws. Start the screw hole using a hammer and an awl. Attach the cone in at least two places.
Dig a narrow 1-foot hole and set the two-by-four in it. Fill back around the board to hold it upright.
