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, aethetics 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 and/or installation of
materials. The panels, flashings and trim shown in this
guide, illustrated over solid and plumb substrate, assume
that the structure has been designed and prepared in

Eave Detail
Gable Detail
Valley Detail
1. In re-roofing applications: cut back and remove
existing shingles and drip edge to be flush with the
eave and gable lines, or as required to install
underlayment.
2. In all applications: apply ATA-Shield** along eave
and up the roof to a point at least 24” beyond
outside face of exterior wall.
3. Install drip edge against fascia trim.
Lay ATA-Guard over eave trim.
4. Trim panel and water leg back to allow for turn
down. Install panel by sliding lower flanged edge
over drip edge. Place clips at water leg.
5. Snap seam or batten over clips after two adjacent
panels are in installed
General Note: Before any installation be sure to lay
ATA-Shield** in all areas where ice & water can occur. 30#
felt or appropriate underlayment should be installed over
the entire roof5When asphalt based felt underlayment is
used install a seperate sheet, such as rosin paper, to
minimize friction.
1. At gable start detail, install gable trim starter
cleat with appropriate fasteners at 2’-0”
into fascia board.
2. At end gable, install cut panel at end with clip.
Bring other panel in and overlap under clip
(see sketch). Be sure to butyl tape panel
end at overlap.
3. Apply double-faced butyl sealant as circled in
sketch. Fasten “Z” closure to panel with pop-rivets.
4. Install starter cleat at end detail same
as start detail.
5. At both ends snap gable/rake trim over starter cleat
and “Z” closure to lock into place. Pop-rivet these
two pieces together with one pop-rivet
per trim length.
1. Install ATA-Shield** approximately 18” up both side
of the valley line.
2. Lay valley pan in valley center. Locate joggle cleat
at 4” to 6” from valley center.
3. Install joggle cleat. Fasten 6” o.c. through butyl
tape and pan into substrate.
4. Turn under edge of panel to slide into joggle
cleat.Place clips at water leg.
5. Snap seam or batten over clips after two adjacent
panels are in installed.
Underlayments: ATA-Shield** is the recommended self adhesive underlayment
for eaves, sidewall and any critical areas exposed to ice damming and
extensive water run off.
Available in 65’-8” x 3’ 3-3/8” rolls (200 sq. ft. per roll).
Underlayments: ATA-Guard* is a polyolefin based, 100%
asphalt free, high strength reinforced roofing underlayment
for use on steep slopes beneath metal roofing.
1000 sq. ft. per roll at 48” wide.

Hip & Ridge Detail
Headwall Detail
Shed Ridge Detail
Hip and ridge applications are handled in the same
manner.
1. Cut “Z” closure to fit between seams and install
in butyl tape.
2. Fasten “Z” closure in bed of sealant at top of
panel. (Use 3 fasteners on 11 1/4” panel,
4 on 12 5/8”, 5 on 15 1/4”)
3. Seal neoprene strips into “Z” closures
4. Snap hip/ridge cap over “Z” closures for it to lock
into place. Pop-rivet one side only to allow for
expansion and contraction.
Notes:
* Trim must be pop-riveted to Z in at least
(1) location.
* Unless otherwise specified, all fasteners for trim
components at 2’-0” o.c.
* Install splice plates at ridge cap joints. Pop rivet
splice to one end of ridge cap to allow for
expansion and contraction.
Install appropriate underlayment to the edge.
1. In standard headwall situation (without venting),
run underlayment from roof plane up headwall.
Install panels up to headwall.
2. Cut “Z” closure to fit between seams and install
in butyl tape.
3. Fasten “Z” closure in bed of sealant at top of
panel. (Use 3 fasteners on 11 1/4” panel,
4 on 12 5/8”, 5 on 15 1/4”)
4. Seal formed neoprene closure into place in
“Z” closure.
5. Install headwall transition over “Z” closure.
6. Apply counterflashing over the headwall trim,
as required.
1. Install metal panel up to the roof peak.
2. Cut “Z” closure to fit between seams and install
in butyl tape.
3. Fasten “Z” closure in bed of sealant at top of
panel. (Use 3 fasteners on 11 1/4” panel,
4 on 12 5/8”, 5 on 15 1/4”)
4. Seal formed neoprene closure into place in
“Z” closure.
5. Fasten starter cleat to face of trim boards at
2” below ridge line.
6. Install shed ridge cap trim over “Z” closure
and starter cleat.

Step 4
Mold the flexible base to
the panel contours.
Step 5
Fasten with 1/4” x 1-1/8” drilling

Tools and Rules:
Basic Equipment Required:
Tie-off ropes, safety harness, long level, ladders, scaffolding with
approved planking, extension cords with approved
ground plugs and services.
Additional Tools:
Metal folding tool, hammer, chalk line, measuring tape, metal cutting
tools - nibblers, drills, hacksaw, utility knife, pop-rivet gun, caulking
guns, layout and combination square, C clamps, sheet metal shears
(including RH, LH, straight and overhand). Power driven screw gun
with proper bits, depth setting nosepiece, variable speed.
Choose the correct equipment and tools to do the job in a safe
manner. Wear safety gear and follow OHSA requirements.
Follow of few simple rules:
1. Never cut the panels with an abrasive cut-off wheel or torch, as
this will damage the finish.
2. Do not weld the trim or panels.
3. Remove any small burrs left by cutting, screwing or drilling.
4. Remove protective masking immediately after trim is installed.
5. Caution should be taken when unloading the panels to prevent
damage.
6. Use appropriate screws for the type of underlayment and long
enough to fully penetrate and secure the panel.
7. The stored materials should be kept dry.
8. Do not cut on finished roof. Remove all drill spirals, chips and
dust immediately.
9. Seal neoprene closures and soft cell foam by applying appropriate sealant to both surfaces.
10. Put appropriate sealant/butyle tape between overlapping trims.
11. Overlap trims in a manner not to impede the flow of water.

Sidewall Detail
1. Install metal panel up to within 1”
of the sidewall.
2. Fasten “Z” closure in bed of butyl
sealant at top of panel with
pop rivets.
3. Fasten sidewall trim over “Z”
closure to face of sidewall.
4. Apply counterflashing over the
sidewall trim, and seal into reglet.
Note Regarding Trim Details
The applicaiton of flashing and trim requires a detailed approach. Consideration should be given to the roof’s geometry and course it
creates for water run-off. Location of gutters and the use of snow retention systems should also be considered. Proper planning
regarding the sequence of material overlap is critical. Sealants, such as butyl tapes and tripolymers, should be used at overlapping
trim edges, in conjunction with exposed fasteners, and to seal flashings and other ancillaries. All fasteners should be properly
tightened and not overdriven at an angle. Fasteners that are too loose can “back out” over time. An overdriven fastener may cause a
depression in the material, which becomes a collection point for standing water.
