All Valley flashings must be installed prior to panel installation. If two or more valley flashings are required, valley must
be installed working from eave to peak. It is recommended that ice and water shield be installed under valley flashing for
added moisture protection.
1. Install Valley flashing against substrate. To hold Valley flashing in place, fasten to substrate with #10-12 x 1" Pancake Head
fastener 4'-0" o.c.
2. Apply a row of Double Bead Tape Sealant across both sides of Valley flashing approximately 5" from center of valley.
3. Properly align and install Offset Cleat on both sides of Valley flashing to accommodate panel hem and fasten to substrate with
#10-12 x 1" Pancake Head fastener 1'-0" o.c.
4. Install panel by engaging field hemmed end of panel (see page 18) to Offset Cleat (see pages 20-21 for panel installation).
5. If two or more flashings are required, lap the flashing over the previously installed flashing by a minimum of 2", placing a bead
of Tube Sealant between the flashings and securing with (2) Pop Rivets in the 1" water diverter.
