SIDEWALL FLASHING INSTALLATION
Installations apply to both R & U-Panels. R-Panel shown in illustration.
1. Install the butyl tape to the top of the roof panel. Make sure the tape is running parallel to the panel ribs and
is in the correct location to line up with the extended flange of the roof transition trim.
2. Insert the sidewall flashing behind existing counter-flashing with the extended flange centered over the butyl tape.
3. Attach the transition trim with #9 x 1” woodgrip screws @ 12“ O.C.
4. If there is no existing counter-flashing, install counter-flashing to wall with appropriate fasteners.
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.
