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.
