Installation of Panels
Roof Pitch
Gulf Coast roofing panels require a certain degree of pitch to ensure proper water drainage.
Florida Building Code allows a minimum pitch of 2/12 for Gulf Rib®panels as long as lap screws
and sealant are applied to the laps to prevent water from siphoning over the ribs(see Fig. 5 on p.4).
Lap screws and sealant are optional when the pitch is 4/12 or greater(4/12 pitch means that there is 4
inches of rise for every 12 inches running horizontally). As a general principle,the less steep the roof,
and the more necessary also that sealant be used at all side-laps. Consult our representative for
recommendations for your particular roof pitch, and about roofing options if you have less than a 2/12
pitch.
Roof Preparation
Oil-canning is a wave-like,rippled appearance extending up the length of the panel after it has
been installed on the roof. Any irregularities in the roof,including uneven plywood joints,warped
plywood, uneven trusses,poor application of underlayment,the use of button caps with felt paper,etc.,
can promote oil-canning. Care should be taken to provide a flat,uniform surface on which to attach
the panels. See page 6 for more details.
Roof Application
Panel installation should begin at the gable end of the roof opposite the prevailing rain-bearing
wind(this will provide added assurance against wind-driven rain being forced under the laps). Measure
one panel width in from the roof edge. At this point chalk a line from ridge to eave. Place the leading
edge of the first panel along this line. It is extremely important that this panel be laid square to the eave
and ridge so that the remaining panels will line up square on the roof frame.It is wise to have a person
at the eave and at the ridge to ensure that the proper panel coverage is being maintained across the roof.
Also be sure that the panels are properly side-lapped(see fig. 7 on page 7).
In applications where end-lapping is necessary,the upper panel on the slope should lap over the
panel that is lower on the slope by about 12 inches. Lesser roof pitches require a greater amount of
panel overlap. All end-lap applications should use two horizontal rows of butyl sealant tape across the
panel and proper fastening to provide a maximum water seal.
An overhang of 2 to 3 inches on the eave is recommended to provide a drip edge,while only 1
inch overhang is necessary where gutters are used. The open panel ribs at the eave can be sealed with
inside closures. For maximum weather-tightness, a row of butyl tape can be applied above and beneath
closure material.
Trimming and Cutting Steel Panels
The best device for cutting steel panels across the profile is either hand snips or a nibbler.
Nibblers, and especially Carborundum blades on electric saws,however,do have a tendency to either
leave hot metal particles that can burn paint surfaces or to leave rust marks on panels and trim. The
same is true of any filings left on the roof caused by the application of screws. Care should be taken to
brush all such particles from roof surfaces after application.
To cut panels lengthwise: Note carefully where the panel is to be cut,and, using a straightedge,
score deeply down the length of the panel with a sharp-pointed utility knife.Folding the panel along the
score mark,and bending back again if necessary,should produce a clean break in the panel.
CAUTION! clean all metal shavings and particles off of roof to avoid unsightly rust stains

Ordering Roof Panels and Screws
Care should be taken to order panels of the correct length to avoid having to make
corrective measures after purchase. Panel lengths should fall 2 to 3 inches short of the ridge when
a vented ridge is desired, and should extend 2 to 3 inches past the eave to allow a sufficient drip
edge (except as noted on pg. 3 concerning gutters). When a roof transition is involved, panels of
the upper portion should be ordered short to allow placement of the transition flashing(see
diagram on p. 10). The Gulf Coast sales personnel are ready to assist customers with information
specific to their particular roof.
Specially-washered screws applied through the flat of the metal is the most recommended
method used to attach roofing panels. 1-inch screws can be used if penetration of only 3/4 inch is
either necessary or desired; otherwise, 11/2 inch screws are usually recommended. 21/2 inch screws
are also available, and are often used by those who adhere to through-the-rib fastening, and for
ridge-cap application. See pages 6 and 7 for more information on screw spacing and ordering.
Ordering and Applying Trim
The most common flashing for metal roofing is the ridge cap,which is used at the peak of a
roof where two opposing roof slopes join. Other flashings include transition flashing,end wall
and sidewall flashings, and valleys(see diagram on right for application). Eave trims include
gable flashing and eave drip, either of which are often applied above fascia trim. When roof pitch
exceeds 5/12 (a 5 inch rise in 12 inches), the slope of the roof should be mentioned when ordering
ridge caps, endwalls, and eave drip. When a steeper roof slope meets a lesser slope,both slopes
should be mentioned when ordering transition flashing.
At the gable edge the use of gable trim adds to the appearance of the structure and protects
the fly-rafter, and sidewall flashing is used where the side of a panel butts up against an adjacent
wall. In either case,the installer should be careful to seal between the gable rake or sidewall and
panel with butyl sealant tape, and to fasten the rake every 6" to 12" up the slope of the roof with
the appropriate screws. If eave drip is used on the gable, the number of 90 degree eave drip
should be specified separately from that used on the drip edge when ordering.
To prevent penetration of water, insects, and debris at the ridge, outside closures should be
inserted between the ridge cap and the top end of the panel. Screws are applied through the ridge
cap, closure, and rib in at least every other rib of the panels.At least a 1%2" (or preferably 21/2")
screw should be used for attaching ridge caps. Self-drilling lap screws can also be used to attach
ridge caps.
Keep Materials Dry!
Paint and finishes of Gulf Coast panels and trim are designed to withstand severe rain and
wet weather conditions. Neither paint, galvanized, or Galvalume finishes,however, are designed to
be in continuous contact with water for long periods of time. Damage will result if uninstalled
panels or trim are allowed to remain wet in storage. Be sure to store material that will not be
installed immediately in a dry location. Wet material should be air-dried and re-stacked if
installation is not planned right away.

Codes allow re-roofing over shingles without the use of battens calculation chart
provided the roof has been checked by a licensed roofing contractor to insure levelness and pullout integrity.
Gulf Rib metal roofing can be separated from the moisture barrier by minimum,nominal 1"x3"yellow
pine battens spaced on maximum 24"centers, or according to ASCE calculations where applicable. Since
direct contact between pressure treated lumber and metal roofing must be avoided in order to prevent
potential corrosion, Gulf Coast Supply sells only untreated battens.
CAUTION: Battens must be fastened to the roof deck with minimum#6 screws at 12" on-center, or two
minimum 8d common or pneumatic nails spaced 8" on-center, or one every 4" on-center(or by applicable
calculations according to ASCE 7-98). Battens must be installed to support the entire width and length
of ridge, cave,hip,valley,and gable-end trims.
For solid decking, at least 15/32-inch structural plywood supported on rafters at a maximum of 24"on
center is required.
If care is taken,metal roofing application can be aided by pre-drilling panels, allowing screws to go
quickly and accurately into the desired spacing. Pre-drilling will work provided that pilot holes are placed
accurately in the proper locations on panels. Purlin spacing must be uniform and carefully measured.
For panel lap details,see Figure S on page 4.

The TRANSITION FLASHING prevents
leakage at the point where two different roof
