Overlapping Metal

The eyebrow window is made of several pieces of zinc-coated copper that hook together with metal tabs. Rosin paper is placed over the existing metal to keep it scratch- and dent-free.

The edge of the zinc-coated copper sheets is folded over and underneath the drip edge to lock it in place.

After bending the metal over the drip edge, the excess will be trimmed with shears.

To keep the metal bent in place, Jason hits the metal to make a square mark, in a meticulous hand-done process called tin knocking.

Crimping the Metal

The overlapping fold creating the drip edge is finished with the use of a metal crimping tool.

Here, Jason is soldering the joint closed. This project took one day to template, one to fabricate in the shop, and a third day of installation, according to builder Jeff Sweenor.
