Introduction
Screw Gun:
Clutch type screw gun with depth locating nose piece
allowing variable torque settings is recommended to
insure proper installation of the screws. The following
sockets will be required:
1
⁄4" and/or
5
⁄16" hex.
Snips:
For miscellaneous panel and flashing cutting
requirements. Three pairs of snips will be required for left
edge, right edge, and centerline cuts.
Electrical Metal Shears:
Used for general metal cutting, such as at the hips and
valleys
Note:
Some erectors prefer to use circular power saws with
metal cutting abrasive blades. While the use of power
saws may be faster, there are some disadvantages
that must be considered:
(1) The edges of metal that have been saw cut are
jagged and unsightly, and are more likely to rust
than sheared edges.
(2) Saw cutting will leave small particles of metal on
the panel surface that will rust and damage the
panel finish if not completely removed.
Chalk Line:
Used to assist in the alignment of panels, flashings, etc
Neoprene Mastic Tape:
1
⁄16" x
1
⁄4" roll of tape used for installation of inside and out-
side profile closures and panel side laps.
Butyl Mastic Tape:

⁄16" x
1
⁄2" roll of tape used for prevention of water infiltra-
tion in flashing to sheet metal applications.
Caulk:
Butyl or urethane sealant used to inhibit water infiltration.
Caulking Gun:
For miscellaneous caulking and sealing to inhibit water
infiltration.

Indelible markers, pencils, or scratching tools.
