TechnoTile Panels
Installation Guide
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 accordance with local building
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 the information regarding suitability 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.
For panel lengths over 15’ consult factory for proper
panel installation procedures.

1. Start by stitching panels together from right to left, using fastener (x). Locate fasteners just below step, at high point of profile. Do not
fasten to substrate until 3 panels are stiched together.
2. Align 3 panel assembly along eave, allowing for 1/4” to 1/2” space within “J” receiver. Locate fasteners (X) in low point of panel.
3. Fasten panel at ridge line with fastener ( O ).
4. Fasten panels to substrate with fastener (O) at location shown.
5. Stitch subsequent panels to previous panel using fastener (X). Install panel at eave and ridge with fasteners (X). Fasten panel to substrate
using (O).
**During installation DO NOT stand on or over fastening point.
Note: For ease of installation, pre-drill the panels at ground level.
NOTE: Use extreme care not to overdrive the fasteners in the main field of the panel.
In high wind zones, additional fastening may be required. Consult governing codes.

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”
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. (2000 sq. ft. per roll).
Hip & Ridge Detail
Hip Cap
Hip Closure
Hip and ridge applications are handled in the same
1. Install panels to meet the Hip/Ridge.
Techo Tile
2. Fasten top closure angle and neoprene closure
(optional) to panel using #12 x 1” pancake screw.
3. Apply butyl tape to top of closure angle, set
ridge/hip cap in place, fasten with stitch screw.
4. Prior to installing the last ridge cap, cut it to size and
fasten the end plug to the ridge cap before installing.
At the Hip:place a hip base over the hip, fasten with
clip (HPC903). Install the panel to the center of the hip
base. Install closure angle, put sealant at the edge of
the panel. Install hip cap.

Note: Do not cut any metal over an installed metal
roof. Do not use an abrasive saw for cutting metal.
When cutting the panels on the hips use a nibbler or a
Tenryu steel - pro blade for ferrous metals or equal. To
prevent metal particles from falling on the panel, turn it
upside down when cutting. Remove all chips and dust
immediately from roof panels.
Top Angle
Headwall Detail
Install appropriate underlayment to the edge.
1. Depending on the wall treatment, cut a reglet in the
2. Install panel to headwall.
3. Fasten top closure angle and neoprene closure
(optional) on the panel.
4. Install headwall trim over the panel while insuring that
the perpendicular section is flush to the wall.

4. Install sidewall flashing prior to wall treatment or
cut a reglet and install counter flashing (not shown).
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.
Pipe Detail
Step 1
Cut on the proper pipe
diameter marked on the
Step 2
Position over pipe and
slide down the pipe.
Step 3
Apply polyurethane
sealant to the bottom of

Step 4
Mold the flexible base
to the panel contours.
Step 5
Fasten with 1/4” x
1-1/8” drilling
fastener every 1-1/2”
around the base.
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
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.
