Installation Guide
The Dutch Seam roof panel, with integral seam, is available in
three widths with seam spacing of 11”, 15”, and 19-1/4” o.c.
The panels are roll-formed from 16 oz. copper, .032 and .040
aluminum and 24 ga. Metallic Coated steel, smooth or stucco
embossed, with or without stiffening ribs. 22 ga. Metallic
Coatedsteel is available, subject to minimum quantity. The
material has a KYNAR 500
®
or HYLAR 5000®quality finish,
in 30 standard colors. The minimum panel length is 2’-0”, the
maximum is determined by shipping considerations. Minimum
recommended pitch is 2:12 depending upon geographical
location and/or roof geometry..
“RAISED” ANCHOR CLIPS
MRS901 - 24 ga. galvanized steel
MRS991 - 22 ga. stainless steel
NOTE: When utilizing the raised clip, all roof edge areas (ridges, valleys, eaves, gables, etc.) must be shimmed 1/4” so trim pieces are on
the same plane as the panels. The raised clips allows for use of hex
head type fastners.
“FLAT” ANCHOR CLIPS
MRS903 - 22 ga. stainless steel
MRS904 - 24 ga. galvanized steel
Clips designed for use with wafer (pancake) headed screws.
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. A TAS cannot assume any responsibility for
the actual selection and/or installation of materials. The
panels, flashings and trim shown in this guide are
illustrated over solid and plumb substrate. It is assumed
that the structure has been designed and prepared in
accordance with local building codes.
Published panel width dimensions are to be considered as nominal
dimensions. Variations in overall coverage may occur at installation due to
typical manipulating of panels during attachment to the roof assembly.

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 (cut) seam and water leg back to allow for
turn down. Install panel by sliding lower flanged
edge over drip edge.
5. Optional end closure is to pop-rivet cap in
place as shown in sketch.
General Note: Before any installation be sure to lay
ATA-Shield**in all areas where ice & water can
occur. ATA-Guard or appropriate underlayment
should be installed over the entire roof. When
asphalt based felt underlayment is used install a slip
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, cut panel to appropriate width to
allow room for clips at gable end. If panel cut off is
3” or wider install cut off portion of panel
underneath last panel w/ butyl tape applied in
between the two panels and install clips before
installing gable assembly.
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 sides 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.
Fasten with clips at 2’-0” o.c.
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 39-3/8” rolls (200 sq. ft. per roll).
Underlayments: ATA-Guard* is a polyolefin based, 100%
asphalt free, high strength reinforced roofing
underlayment for use beneath metal roofing on steep
slope applications. 1000 sq. ft. per roll at 48” wide.

Hip and ridge applications are handled in the same
manner.
1. Cut “Z” closure to fit between seams and install
in butyl tape.(Use 3 fasteners on 11” panel, 4 on
15”, 5 on 19 1/4”)
2. Seal neoprene strips into “Z” closures (formed
neoprene for ridge; straight neoprene for hip).
3. 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 one
location to control thermal movement.
* Unless otherwise specified, all fasteners for trim
components should be spaced 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. Fasten “Z” closure in bed of sealant at top of
panel. Seal formed neoprene closure into place
in “Z” closure.
3. Install headwall transition over “Z” closure.
4. Apply counterflashing over the headwall trim,
as required.
1. Install metal panel up to the roof peak.
2. Fasten “Z” closure in bed of sealant at top of
panel. Seal formed neoprene closure into place
in “Z” closure.
3. Fasten starter cleat to face of trim boards at
2” below ridge line.
4. Install shed ridge cap trim over “Z” closure
and starter cleat.

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/butyl 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
as shown.
3. Fasten sidewall trim over
“Z” closure to face of sidewall.
4. Apply counterflashing over
the sidewall trim, and seal
into reglet.
NOTE: Trims should be fastened
to substrate and sidewall using a
#12 x 1” wafer head screw.
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. 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.
