D. Fold down top flap of water resistive barrier (3D).
E. Apply flashing tape to diagonal cuts. Cut
pieces of flashing tape at least 1" longer than the
diagonal cuts in the water resistive barrier. Apply
the tape covering the entire diagonal cut in the
water resistive barrier at both upper corners of
the window. If vertical cuts were also made, apply
flashing tape to them in the same manner.
Note: The top tape must overlap the tape below
it to divert water properly. Be sure to overlap
the top corners (3E).

C1. Apply top flashing tape to circle top windows. Several pieces of flashing tape
will be needed to cover the top fin. Start taping from the sides of the window
working toward the peak. To determine the length of cuts, hold the tape along the
radius, and cut the tape just past where it leaves the top fixed extruded fin or for the
flexible fin, just past the flexible weather strip. The top tape must overlap the one
beneath it in order to divert water properly. The sharper the arc of the window, the
shorter the pieces of tape will be.

C2. Apply top flashing tape to an angle top window 1/2" up onto the frame
cladding, over the top fin onto the sheathing. On the short side of a trapezoid
window, do not allow the side flashing tape to extend higher than what the top
tape will cover. Fold the overlapping tape down, and press all tape down firmly.
