TRIM CONSIDERATION:
Minimum 1" trim thickness is needed as Panels stack at a depth of roughly 15/16" for the 7"
reveal. If additional trim depth is desired, you can place a spacer under the trim (Fig. 8C & 8D).
GABLE INSTALLATION:

Because of the volume of water that can pour down
a sloped roof, one of the most critical flashing
details occurs where a roof intersects a sidewall.
The roof must be flashed with step flashing. Where
the roof terminates, install a kickout to deflect water
away from the siding.
It is best to install a self-adhering membrane on the
wall before the subfascia and trim boards are nailed
in place, and then come back to install the kickout.
Figure 7, Kickout Flashing To prevent water from
dumping behind the siding and the end of the roof
intersection, install a "kickout" as required by IRC code R905.2.8.3 : “…flashing shall be
a min. of 4” high and 4” wide.” James Hardierecommends the kickout be angled between
100° - 110° to maximize water deflection

Installation over sheathing is recommended (Required for Individuals) for gables.*
1) Find the center stud of your of your Gable and snap a caulk line down
2) Measure out 16”* to both the left and the right of the center line and snap a caulk line
3) Measure up 2” if you are off a roof line or ¼” if you are starting above a band board
4) Set the bottom of your 1 ¼” starter strip at that line
5) Place your 8 ¼” Starter Course -bottom level with the bottom of the starter strip
6) Set your first row of Shingle - starting the first piece at the vertical line left of center
(If you are using staggered edged shingles Trim down the first row to the shortest shingle length)
7) Drive nails approximately ¼” above Key ways 5 per full panel Center Nail can be either one of the keyways.
(Stay by keyway to avoid shiners) (EX1) Blue Dots show nail placement
8) Measure up 7” with straight and 6” with Staggered edge and snap a caulk line to get your proper exposure
9) The second row will start at the center line
10) The Third row will start at the line right of center
11) As you work your way up the gable make sure you Keep your Cut Pieces you will use the pieces on the edges of the gable (EX2)
12) Edges Gable butting into trim leave a 1/8” Gap (for house movement and Caulking)
13) Make sure to sure siding nails on the small pieces on the edges (Do not use a trim nail to install!)

*Panels can also be installed direct to stud up to 24"OC.
Note: Snapped chalk lines help guide installation, when installing straight edge panels or Individual shingles use a straight edge on bottom edges if uniform straight edge is desired.
BLOCKED PENETRATIONS
Penetrations such as hose bibs and holes 1 ½” or
larger such as dryer vents should have a block of
trim around point of penetration.
