along the cut edge every 6" so the raised tab is on the outside face. Install undersill trim under the window, as a receiver for the cut siding. Undersill trim is used any time the top lock has been removed from the siding. Furring may be needed to maintain the face of the panel at the desired angle. Install the siding panel, making sure the tabs (from the snap lock punch) lock into the -undersill trim. Sidewall Flashing at Roof Lines Install the siding panel, making sure the tabs (from the snap lock punch) lock into the undersill trim. Run the siding until the last full course under the roof area. Cut a diverter from aluminum trim sheet, making sure it sits on the nail hem of the last full course. Also make sure to slip it behind all J-channels and roof flashing (similar to flashing the bottom of window detail). As an alternative to the diverter, create a "kickout" from metal flashing. Cut the next piece of siding, making sure the vertical lap falls behind the roof flashing and roof J-channel. Cut a small piece of siding that will be placed on top of the previous piece of siding and sits in the roof J-channel. Install the remaining course of siding. Water running behind the panel will be directed by the diverter into the butt of the panel, draining out in the weep holes. Note: "Kick-out flashing" is an additional flashing strip that extends beyond the edge of the
