Review and understand complete
guide before beginning installation.
This guide has been prepared as
suggested details for particular design
conditions. Each condition has certain
limitations to performance, aesthetics or
economics. Professionals qualified to assess
this information for a specific projects 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, flashing and trim shown in this

to ice damming and extensive water run off.
Available in 65’-8” x 39-3/8” rolls (200 sq. ft. per roll).
Underlayment
s: 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. Install panel to hip/ridge line. Cut panel to size.
Install “Z” purlin at ridge of roof. Overlap and
fasten cut panel section to “Z”.
2. Seal panels at hip/ridge line using
Adhesive Closure Roll between panels.
3. Attach Ridge/Hip Cap to panels with Stitch
screws at 15 3/4” o.c. Fasten the side of ridge.
1. Install panels to headwall area. Cut panel to
size. Install “Z” purlin at wall. Overlap and fasten
cut panel section to “Z”. Lap is required to allow
proper fastening of “Z” purlin at top panel.
2. Seal top with neoprene closure to panel, set in
sealant. Be sure headwall trim will
cover neoprene.
3. Place headwall trim to wall. Stitch fasten to
top of panel at 15 3/4” o.c.
4. Install counter flashing into reglet over headwall
transition. Seal into reglet with appropriate
sealant or place wall treatment over
headwall trim.
1. Install panels to peak. Cut panel to size.
Install “Z” purlin at wall. Overlap and fasten cut
panel section to “Z”. Lap as required to allow
proper fastening of “Z” purlin at top panel.
2. Seal top neoprene closure to panel. Be sure
shed ridge cap will cover neoprene.
3. Fasten Starter Cleat at peak. Fastener spacing
to be 12” o.c.
4. Place shed ridge cap to wall. Stitch fasten to
top panel at 16” o.c.

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 these 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 ATA-Shield (self adhesive underlayment)
along roof plane and up sidewall.
2. Install a 2 x 4 flat on roof plane and tight against
entire length of sidewall.
3. Cut panel to desired length leaving 1/4” to 1/2”
space away from sidewall to allow for
thermal expansion.
4. The built-in purlin must be notched 1-1/2” in height
and 3-1/2” in length in order for the top surface of
the panel to rest on top of the 2 x 4.
5. Install step flashing to each panel tight against
sidewall and on top of 2 x 4 making sure step
flashing is on top of lower panel for
proper draining.
Note Regarding Trim Details
The application of flashing and trim requires a detailed approach. Consideration should be given to the roof’s geometry and the 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 flashing. All fasteners should be properly tightened, over tightening creates a dimple in the material, which becomes a
collection point for standing water and damage the weather seal on the fastener.
