Review and understand complete guide before beginning
installation. This guide has been prepared as suggested
details to particular design conditions. Each condition has
certain limitations to performance, aesthetics or economics.
Professionals qualified to assess this information for a
specific project should determine that the selection and
installation are made to their requirements.
ATAS cannot assume any responsibility for the actual
selection, use and/or installation of materials. The panels,
flashings and trim shown in the guide, illustrated over a
solid and plumb substrate, assume that the structure has
been designed and prepared in accordance with local
building codes. Care should be taken during installation
not to damage panels and finish. May void product
warranty.
Published panel width dimensions are to be considered as
nominal dimensions. Variations in overall coverage may
occur at installation due to typical manipulation of panels
during attachment to the roof assembly.
Permashake II panels are simulated wood shakes
manufactured from 29 gauge steel with a Kynar 500® PVDF
or Hylar 5000® PVDF nish. They are available in 6 colors.
Panel coverage is 12” x 36”. Minimum recommended roof
pitch is 4:12.
There are twelve (12) Permashake II panels packaged per
carton. Approximately thirty-four (34) panels equal a square.
Panels are always installed left to right and should have a
minimum of four (4) top anchor clips and one (1) side anchor
clip.
PANEL INSTALLATION - In environments where ice and
water may dam, apply self-adhered roong underlayment in
accordance with local building codes. Then apply appropriate
underlayment over balance of roof. Snap a vertical and
horizontal line to square up the plane with the eave. Start
at the bottom left hand corner of the roof plane with a full
length panel. Install shingles in a left to right manner from
eave to ridge. See right for stagger method of installation.
Fasten panels to solid substrate with galvanized steel clips.
Manufacturer recommends the use of exterior grade #10-16 x
1 ½” wafer head screws.

CHANNEL TRIM
1. When applying a re-roof application, cut back existing
shingles and drip edge as required to apply appropriate
underlaments.
2. Apply self-adhered roofing underlayment on roof deck
areas where ice & water damming can occur. Extend this
underlayment over fascia board. Install drip edge as tight as
possible against the fascia trim. Space fasteners at maximum
of 12” o.c. Overlap eave trim pieces a minimum of 3”.
3. Lay full width of underlayment (roofing felt or equivalent)
on top of the drip edge. Apply butyl tape on top of drip edge
and fasten starter cleat through butyl tape and eave trim into
substrate with front face up as shown at right.
4. Install panel only after the gable closure is installed (see
below). Install by sliding lower flanged edge between starter
cleat and drip edge. Square the panel in the J channel at the
gable edge and fasten with clips and exterior grade #10-16 x
1 ½” wafer head screws.
Gable Detail
1. Install drip edge over underlayment. Overlap on
top of drip edge at the eave.
2. Apply butyl tape along drip edge as shown to
the right. Lay the channel trim along the gable
edge. Overlap channel at a minimum of 2” to 4”
working upward from the eave. Fasten channel as
shown at right.
3. Align the first shingle into the J channel and
snap a line across the roof plane. (See panel
installation section)
Headwall Detail
1. Install metal shingles up to the headwall. Shim the last
row of panels if necessary as shown at right.
2. Lay headwall trim over the shingles while insuring that the
vertical section is flush against the headwall. Use double
sided butyl tape between the panel and trim assemblies.
3. Fasten through butyl tape and shingle into solid substrate.
Use #10 x 2” long gimlet point screw with 5/16” cast zinc
color matched hex washer head and EPDM washer at 24” o.c.
4. Apply wall covering over the headwall trim as required, or
install wall paneling.
