How to Make a Decorative Window Cap Flashing
A few additional bends of your copper piece turn this functional window cap flashing into a decorative detail.
In a recent “Building Skills” department and companion video, John Mahan demonstrated the basics of how to solder and shape copper cap flashing. This flashing is installed on top of a window’s head casing and serves as the first line of defense against water infiltration, thereby preventing mold, rot, and insects. In this Members Only video, Mahan goes beyond the basics to show you how a few additional bends on the sheet-metal brake turn this functional flashing element into a decorative one as well.

This man has some serious skills. :)
I did this with Aluminum and it came out really sharp.
Customer loved it
I needed 6 rolls of 8" x 10' 16 ounce copper slit down to 4" x 10' and then bend 13 individual caps for my windows. I'm replacing my vinyl siding with red cedar shingles as well as all the original trim on my 1920 bungalow. Tough to find a metal break for rent and available. Home D rents but it's always out. Called a guy. He wanted $490 for an hours work bending. Ended up renting the brake for $60. Followed John's videos and PDF's and made the caps myself. Couldn't have come out any better. Time to solder. Thanks John!
