1 WORK INCLUDED

(1) Step 1

Use a standard 225 mm (9”) long step flashing and scribe the fold lines as shown on the illustration. Note that the down-slope upstand is bent at a 110-degree angle to the slope. No cutting is needed or appropriate; the flashing is formed with folds, bread-pan style.

(2) Step 2

Fold the bottom end of the flashing as illustrated, so that the bottom upstand aligns with the vertical bread-pan fold made in the next step.

(3) Step 3

Fold the back flap around and behind the main upstand, bread-pan style.

(4) Step 4

If required or desirable, cut a capillary notch in the bottom upstand (illustrated), and trim the upstand to suit the aesthetics of the roof.
