ENDWALL TO ROOF FLASHING INSTALLATION
Details are subject to change without prior notice.
1. Insert the endwall flashing (#0725) behind the existing wall counter-flashing and attach to the wall using
appropriate fasteners. Make sure the receiver hem of the endwall flashing is resting on the top of the roof sheet rib.
If required, cap the ends of the trim by cutting and folding a tab. Remove the hems before making the folds.
2. If there is no counter-flashing, install counter-flashing using appropriate fasteners.
3. Field cut enough #0322 metal closures to complete application.
4. Slide the 5/8” lip of the field cut metal closure into the receiver hem of the endwall flashing and position the
closure on the roof.
5. Attach with one woodgrip screw, centered between each rib, through the hem of the endwall flashing
and metal closure, into the decking. Care must be taken not to over-tighten the screws as this will distort
the trim and closure. The screw hole can be pre-drilled, if desired.
6. All end laps should be at least 4”. Remove 4” of the hem on the overlapping piece and secure to the
overlapped piece with caulk and stitch screws.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
NOTE: To comply with Texas
Windstorm Certification Testing,
#12x11 SDT Type A screws must
be used in place of the #9
Woodgrip screws.
