This guide has been prepared as sug-
gested details to particular design condi-
tions. Each condition has certain limitations to perform-
ance, aethetics or economics. Professionals qualified to
assess this information for a specific project, should deter-
mine 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, illus-
trated over solid and plumb substrate, assume that the
structure has been designed and prepared in accordance
with local building codes.

PANEL INSTALLATION - In environments where ice and water may dam, apply ATA Shield ** underlayment over entire substrate. Begin installation
over solid deck by applying ATA Shield * around perimeters of roof with a minimum of 36” coverage. Then apply ATA Guard * or appropriate underlay-
ment over roof deck. Snap a vertical and horizontal line to square up the plane with the eave line. 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 below for stagger methods of installation. Fasten
panels to solid substrate with galvanized steel clips using a minimum of three (3) to a panel. Manufacturer recommends the use of 1” wafer head
screws.
