What's in this manual? It's 50 pages long ... do I actually need to read it? What is this document for?
All fair questions. We hope this manual will be useful if you are curious about any of these questions.
What kind of products does Gulf Coast have? What metal and color choices are available?
See Product Selection (see page 3).
What should I be thinking about when I am designing or -specifying a metal roof (as a property owner,
a designer, and/or an installer)? What are some important considerations to keep in mind?
See Roof System Design (see page 5).
How does a metal roof get installed? Can I do this myself? See Installation (see page 8).
How can I figure out how much material I need (and how much will it cost)? See Estimating Materials (see
page 11).
What about trim? What kind of trim do I need and how is it installed? See Trim Details (see page 13).
How many fasteners do I need? What spacing should I use? How can I be sure my roof won't blow away? See Load
Tables (see page 18).
What about building codes? See Appendix B (see page 31).
What is the HVHZ, and what do I need to know about it? Short answer: if you're not in Miami -Dade or Broward
counties in Florida, you can ignore this. If you are working those two counties, see Appendix C (see page 34).
Even with 50 pages, it's just not possible to fit everything in one manual. Please check out our website at

Product Lineup
Gulf Coast Supply & Manufacturing produces the following four exposed fastener panel profiles:
GulfRib' is a panel made popular initially by its use in agriculture
applications. GulfRib'n' has a 3/4"tall rib spaced at 9" and a total panel
coverage of 36" This panel has also gained popularity in residential and light
commercial construction and is available in 29ga steel, making it a very cost-
efficient profile.
5V Crimp is the timeless old Florida look that is most common in residential
settings but is also suitable for light commercial applications. 5V Crimp has a
r46"tall rib spaced at 12'; with 24"of panel coverage. Double ribs on the panel
edges create the classic 5V look.
GulfPBR'' is a typical R-Panel and is commonly used for residential and
commercial applications. GUIfPBR'' has a 1-Y4" rib at 12'; with a panel
coverage of 36" The taller rib creates a stiffer panel for longer open spans (up
to 5') and provides better resistance to flooding of the rib.
GulfWave' is a classic corrugated panel. It is used in residential and light
commercial roofs but is also commonly installed as wainscoting, interior
accents, and other architectural uses. GulfWave'' has a corrugation depth of
3/4" (from peak to trough), with peaks spaced at 8"and a total coverage of 29".
Most profiles are available with striations (as seen in 5V Crimp above), mini ribs (as seen in the GulfRib' above), or
flat.
Panel Materials
Gulf Coast Supply produces roofing panels in 55%aluminum-zinc alloy coated 29ga, 26ga, and 24ga steel. Some
panels are also available in 0.032 and 0.040 aluminum as well as stainless steel and pure copper. Depending on the
project specifics, additional materials may be used for limited production runs. Not all panels are available in all
materials —typically exposed fastener panels are produced from steel.
Paint Options
Most panels are offered in three paint options. The Kynar500e/ Hylar® 5000' 70% polyvinylidene fluoride (PVDF)
is the highest performing paint available, with superior UV resistance and outstanding color retention. The PVDF
resin provides excellent chalk resistance while mostly ceramic pigments hold color well over time. The silicone
modified polyester (SMP) chemistry has improved vastly over the years, but still lags the PVDF resins in chalk and

t
color performance. SMP paints are harder and can offer more scratch/abrasion resistance, but the hardness can
also make them brittle. Finally, a mill -finish, bare/unpainted steel is available with an acrylic fin ish.The mill finish
metal has a hot dip AZ55 aluminum -zinc coating (generally superior to galvanization and sometimes referenced
by the tradename Galvalume®). Note that the mill finish will oxidize and darken over time and may not occur
evenly. The mill finish is also susceptible to smudges or other markings during installation.
Warranties
Gulf Coast Supply & Manufacturing offers warranties for both corrosion of the base metal, as well as paint
performance (chipping/peeling/cracking, chalking, and fading). Please refer to www.gulfcoastsupply.com or
contact a sales representative (888-393-0335) for the most recent warranty information.
Life -Cycle Costs
A common objection to metal roofing is the perception that it is more expensive. This is really only a high "initial
cost" —when considered over the life of the facility, the total "life -cycle cost"of metal is often lower than other roof
options. The life -cycle cost considers the total expected cost to maintain and repair a building system over the
entire life of the building. For example, a shingle roof might be expected to last 20.years while a metal roof may be
expected to last 40 years. This means the property owner would have to purchase two shingle roofs but only one
metal roof over 40-year period. When considering life -cycle costs, the durability of metal roofing often results
in a lower total cost of ownership than shingles, despite a -higher initial cost. See the "Metal vs Shingles" page at
www.gulfcoastsupply.com, which links to an ongoing study that projects 60-year life expectancies for some metal
roofs.

Design Philosophy
The instructions and details presented in this manual are the manufacturer's recommendation for a quality
installation of metal roofing products produced by Gulf Coast Supply & Manufacturing. The manufacturer
recognizes there are multiple acceptable methods of installation and that design and construction practices can
vary widely by contractor, designer or locale. Furthermore, the recommendations contained herein are intended
for a typical roof; the specifics of any installation may drive different requirements.
The design of a facility falls along a
spectrum which must balance cost and
risk. An attempt to completely eliminate Some Ma
risk would result in a cost -prohibitive
design that is overly conservative Overly
Uystem Failure)
(refer to image). On the other hand, a (System failure) _~ conservative
design which accepts too much risk (Too Costly)
may fail and cause property damage,
serious injury, or death. It is the responsibility of the designer to specify a design which establishes a balance
between cost and risk that is acceptable for the intended facility use. Even an outstanding design will still
require some maintenance and/or repair throughout the lifespan of the facility.
The minimum standards in this manual provide a low cost, generally low -risk installation. Recommended
components or design standards will further reduce the risk of water intrusion, wind damage, or other
maintenance/repair needs.
Water Tightness:
Pipes and other penetrations are common areas for leaks to develop. When these penetrations are necessary,
take extra care to flash and seal properly.
Installing the proper trim items and panel closure strips will reduce the risk of water intrusion at roof edges
and transitions, which are high -risk areas for leaks to develop.
Use of a quality underlayment on the decking beneath the metal panels provides an important secondary
water barrier. Underlayment is required by code in many areas, and Gulf Coast Supply recommends it in most
scenarios. Generally speaking, a synthetic self -adhering (peel and stick) underlayment provides the highest
level of protection, synthetic through -fastened underlayment provides a mid -level water barrier, and asphalt
roofing felt provides the minimum performance required by code (when applicable).
Gulf Coast Supply highly recommends use of full length panels that run from ridge to eave in order to
eliminate end laps (another common source of leaks).
Exposed fastener panels (panels fastened directly through the panel) will have hundreds of holes where the
fasteners are installed. The use of properly installed roofing screws with sealing washers should effectively seal
these penetrations. A hidden fastener system (sometimes referred to as a standing seam roof) can virtually
eliminate the risk of water intrusion at the fastener.
Metal on metal connections are typically not watertight unless a sealant (butyl tape or caulk) is applied
between the metal pieces. Therefore, it is critical that sealant be used when watertight connections are
required. Some examples of metal on metal connections are panels attached to trim, trim attached to trim,
and panels attached to panels.

Wind Performance:
The wind load which a roof experiences is based on location and
dimensions of the building. Discontinuities, or areas where the roof
changes direction/slope, will be exposed to higher pressures than
the field of the roof. Typically roof pressures are described in three
zones: zone 3 consists of corners, zone 2 includes edges (ridges,
eaves, & gables), and zone 1 represents the field.
In most cases, exposed fastener roof systems fail when the
fasteners pull out from the decking. Therefore, ensuring proper
installation of fasteners is critical to achieve the desired wind
performance. Gulf Coast Supply provides load tables which
indicate the required fastener spacing for each roof zone in

different wind speeds.
Roofs are typically designed primarily for"uplift" loads —the effect of a strong wind will essentially pull the
roof upwards. Therefore, it is important to think of wind performance as a continuous"load path"When the
wind pulls upward on a roof, that force is transmitted by fasteners to the roof deck, which transfers the force
by fasteners to the rafters/roof structure, which further transmits to the walls, and on to the foundation.
The weakest link along the load path will cause the system to fail, even if all other components perform
satisfactorily. A metal roof panel may be able to resist hurricane force winds, but if the fasteners have been
overtightened and stripped out the plywood decking, the system may not perform as desired. Structural
assessment and design can be a complicated endeavor, and the services of a qualified entity may be helpful/
necessary.
Oil Canning:
Oil canning is a visible waviness in the flat areas of a roofing panel. It is an intrinsic aspect of cold formed, light
gauge metal panels but is typically an aesthetic issue only. Oil canning is not a defect and is not a reason for
rejection.
The risk of oil canning can be reduced by selecting heavier gauge metals, specifying striations (large, flat
areas are most prone to oil canning), ensuring a completely flat/square/level deck (deck imperfections will
reflect through the panels), properly driving fasteners (over driving creates stresses in the panel), and ensuring
proper handling and storage during construction (twisting/bending panels will introduce internal stresses).
Dissimilar Metals E Galvanic Corrosion
Dissimilar metals in contact are at risk for galvanic corrosion. To avoid this, a roof system must be properly
designed and specified to ensure that dissimilar metals are not in contact with roof panels or located upstream
of roof panels. Copper and lead present a particularly high risk of galvanic corrosion, and materials containing
copper and/or lead must not be installed in contact or upstream2 of metal roof panels. Damage due to galvanic
.corrosion is NOT covered by warranties. Note that most treated lumber contains copper -based substances —metal
roof panels installed in contact or downstream from treated lumber are at increased risk of galvanic corrosion and
rust -staining.
' Since virtually all metals will leach some particles into rainwater, any case of dissimilar metal installed such that rain runoff will travel from
the dissimilar metal before contacting a metal roof panel is considered "upstream,"and presents an increased risk of galvanic corrosion and
rust staining.

Roof Slope/Pitch
All Gulf Coast Supply roofing panels can be installed on slopes of 3:12 and
greater (3"of vertical rise/drop for every 12"of horizontal run). For low slope
installation below 3:12, please contact Gulf Coast Supply. Most panels can be
installed to 112 slope if the side laps are'sealed, and even lower slopes may be
permitted on a case -by -case basis.

Storage and Handling
Metal roofing panels are designed to shed water, not to hold water for
an extended period of time. Thus, it is important to store panels dry— uW Ely..aOH&l
/ fopennit9,ibw)
position a stack of panels away from standing water, elevate one end
to allow water drainage, and cover loosely with a tarp as shown in the
image. Storing panels under cover or indoors is recommended. Panels
must NOT be stored in vicinity of: saltwater, corrosive chemicals, P°"eIF
aevafeem or PAX"u
pressure treated lumber, fertilizer, or other chemicals. When handling
panels, be sure to support the panel to avoid damage from bending
of the panel. In general, no more than 1 /3 of the length of a panel should be unsupported.
Preparing the Roof Deck
In most cases, the rafters or roof trusses will be covered with a sheathing material (plywood, OSB, etc.) which is
then covered with underlayment.The design and construction of the roof structure and decking is outside the
scope of this document. However, it is important to note that a poorly prepared roof deck will likely result in a
poorly installed metal roof. The roof panels will generally match the shape of the roof deck —if there are ridges in
the underlayment, uneven decking or other high areas, these imperfections will likely show through the metal
panels.
Order of Installation
Typically, eave drip, valley trim, and transition trim are installed with the underlayment during dry -in: Metal panels
are installed next. Finally, ridge/hip caps, gable trim, and end/side wall trim are installed last. (Note that not all
trims will be required in all cases.)
Installing Metal Panels
Start atthe gable end opposite the prevailing rain -bearing wind. (If
there is not a prevailing wind direction, start at either gable end.)
Install the first panel with the overlap side along the gable. It is
common to measure one panel width along the ridge and the eave,
and to chalk a line between these points. (See images) Aligning the
panel edge with this line will help set the first panel. It is extremely
important to set the first panel square; any deviation will ripple
across all of the remaining panels.
GulfRib', 5V Crimp, and GulfPBR"A panels have a specific underlap
side and an overlap side.The underlap side must be installed towards
the field of the roof and the overlap edge of the next panel installed
above the underlap edge of the previous panel. This places the
bearing edge of the underlap on the decking or purlins, and ensures
that the anti -siphon channel performs properly. Please refer to the
schematics below to identify the over and underlap edges. Note that
Gulf Wave' does not have a specific underlap or overlap side.

Fastener withdrawal or fastener pullout is the most likely failure mode for an exposed fastener roof system.
Furthermore, fasteners are a high -risk area for leaks: Therefore, correct installation of fasteners is critical to
ensure performance of the roof. Overtightening can strip out the plywood decking (or similar) and create a
depression in the panel, while under -tightening will not provide a watertight seal (refer to image). Ensure that
fasteners are driven straight and that the washer is compressed slightly without creating a depression in the panel.
Use drill/drivers, screw guns or similarwith
maximum RPM of 2,500. Depth -sensing
nose pieces
are recommended to ensure consistent tightening of
fasteners. Impact drivers are not recommended as they Good Under- Over -
may overdrive or damage the fastener. Tightened Tightened
Install the number and spacing of fasteners as required by the load tables contained in the product approvals and
this document.
Remove metal shavings/fragments that are produced at each screw hole and cut edge. Failure to brush off
or otherwise remove all of these metal shavings will result in rusting.
Field Cutting Metal Panels
Tin snips or electric nibbler/shear tools are recommended for field cutting panels. Cutting a metal panel with any
device will create small slivers of metal that must be removed from the panel to avoid rusting or damage to the
panel. The use of circular saws or other abrasive cutting tools is not recommended as these tools will create
significant heat which can burn the panel coating and may produce tiny, hot metal particles which can become
embedded in the panel finish. Both of these conditions are likely to result in premature rust and corrosion of the
panels.
Care and Maintenance
Gulf Coast Supply recommends that a metal roof be assessed annually to check for any damage or deterioration.
This can be done from the ground in most cases (binoculars may be helpful). Consider visually assessing the
following items:
a. Look for water stains both outside and inside the building (if possible) that may indicate a leak.
b. Check for missing, loose, or deteriorated fasteners. Thermal expansion and contraction of the metal,
foot traffic, and wind -induced movement may back fasteners out or otherwise compromise the fastener
performance. Overtightened/over torqued fasteners are especially susceptible to back out over time.
(888) 393-0335 1 www.gulfcoastsupply.com m (888) 393-0335 1 www.gulfcoastsupply.com U
Tighten or replace fasteners as needed.
c. Assess condition of any visible sealant. Metal roof longevity studies indicate that sealants are often the first
component to fail. Replace cracked or peeling sealant.
Remove loose debris and clean the roof as needed. Mild biodegradable cleaners, household ammonia, or
household bleach may be used when necessary (dilute 1/2 cup of 5% bleach in 1 gallon of water). Consult the
warranty information or contact the manufacturer for more information on your specific system.

Panel Length
Panel lengths can be determined by measuring the distance from ridge to eave, or
estimated via the following method:
Divide the building width in half and multiply by the appropriate slope factor
shown. Add 1 "-2" as desired for overhang at the eave, and take off 1/2" to 2" gap at
the ridge (if desired). For example, a 30'wide building at a 5/12 slope would be:
30' divided by 2 is 15; times 1.083 is 16'-3" (round to nearest inch). Add 2" for eave
overhang and subtract 1"for a gap at the ridge for a final panel length of 16'-4".
Plumber of Panels
Each panel has a specified "coverage" The actual panel width will be greater than
the coverage, however part of each panel will be overlapped by the adjacent
panels, so the net exposed width is the coverage. To determine how many panels
will be required, divide the eave or ridge length by the coverage. Round up to the
nearest whole number. For example, a 30'-6" ridge length with GulfRibre panels
(36"coverage) would need: 30'-6"divided by 36"for 10.17 panels, which is rounded
up to 11 panels. It is often a good idea to order one or several extra panels.

The number of fasteners depends on the panel selected, the fastener pattern in use, and the fastener spacing. The
table below can be used to determine the number of fasteners by multiplying the square feet or linear feet by the
factor shown. For example, consider a 525-square foot roof with the GulfRib' panel using one fastener per rib, at
24" on center (o.c.). This is pattern A for GulfRib", and will require 525 square feet times 0.67 fasteners for 351.75
fasteners, which will be rounded up to 352. Most fasteners are sold in bags of 250, and it is a good idea to order
10-15% extra fasteners just in case.

Appendix E, Section 2 (ASTM G 85), and shall be product control listed. All cartons or carton labels of"tin caps;'
"cap nails" or prefabricated fasteners with integral heads shall be labeled to note compliance with the corrosion -
resistance requirements.
FBC 1517.E Metal Roofing Accessories
All metal accessories for roofs shall be not less than 26 gage G-90 galvanized or stainless steel, 16 ounce copper,
0.025-inch (0.6 mm) thick aluminum, lead sheet with a minimum 2.5 pounds per square foot (12.2 kg/mz) or
equivalent noncorrosive metal alloys or composite materials manufactured for use as roof termination. All
composite and nonmetallic flashing materials shall have a product approval.
FBC 1517.6.1
Metal accessories may be of a manufactured, shop -fabricated or field -fabricated type, providing the materials
and fasteners are in compliance with the minimum requirements of this code and shall be sized, designed and
installed in compliance with methods set forth in RAS 111.
FBC 1517.6.2
Gravel stop or drip edge profiles shall be as follows.
FBC 1517.6.2.1
The vertical face shall be a minimum of 1 % inches (38 mm) and shall extend down not less than 1/2
inch (12.7 mm) below the sheathing or other member immediately contiguous thereto. In all cases, the
deck flange shall be not less than 2 inches (51 mm) in width. Gravel stop or drip edge shall be sized,
designed and installed in compliance with RAS 111.
FBC 1517.6.2.2
Gravel stop or drip edge shall be designed so that the bottom (the kick of the metal) of the drip
edge shall have a minimum of r/2-inch (12.7 mm) clearance from the structure.
Metal trim (referred to interchangeably as trim or flashing) is a critical component to provide a watertight roofing
system and is required by code in specific areas. Flashing/trim consists primarily of specifically formed metal
pieces to provide watertight details around corners, edges, penetrations, and other areas of the roof which are
likely to leak. Some building codes may require more stringent or different standards than those contained
herein —the more stringent requirement always takes precedence. Consult the applicable building code for
each project to ensure code compliance. Gulf Coast Supply maintains a number of Florida Product Approvals
(FPAs) that indicate code compliance with the Florida Building Code (FBC)3 and the High Velocity Hurricane Zone
(HVHZ, defined as Miami -Dade and Broward counties)'. These products must be installed per the requirements of
the FPA and this detail manual.
Because intended uses of a structure and the design thereof will vary widely, it is not possible to prescribe a single
standard that is suitable in every situation. Therefore, the owner, designer, and installer must develop and agree
on the appropriate details and specifications to employ. For example, consider an unoccupied, 100 square -foot
shed that is not located in a hurricane prone region. A much lower quality roofing system may be acceptable and
appropriate for this use. Conversely, a large multiple story, multiple family residence on the beach in south Florida
will have a much greater requirement for watertightness, structural performance, and resistance to wind driven
rain.
The details and commentary in the following pages are intended to provide a baseline, minimum standard that
is acceptable for a low -end application (e.g. the shed described above). It is ultimately the owner's responsibility
(often delegated via contract to a designer and/or installer) to determine and select the details and specifications
that are appropriate for each project. As the requirements of each project will vary, Gulf Coast does not
warrant the fitness or suitability of any details or design for any specific projects. Gulf Coast Supply may
provide advice on design and details; however this is strictly limited to a manufacturer's recommendation, and
does not guarantee code compliance or fitness for use with a specific project. The services of a design professional
should be employed if this is required.

Eaves
The bottom edge of the roof, or the eave, is protected with eave drip
to provide a continuous metal surface for water to runoff from the
roof to the ground. Fascia trim is recommended below the eave drip
to fully cover the structural member. Except in unique cases, eave drip
is installed before the panels.
4" overlap (minimum) recommended in Florida. I" overlap
in other locations. Sealant (caulk or butyl tape) to seal laps is
recommended, but not required.
Fasten into roof deck with low profile fastener (or other fastener)
to match panel fastener spacing along eave.
Fastening of exposed face is not required for faces less than 4" If desired, fasten through the exposed face
using fasteners with sealing washers.
Closures may be omitted if owner, designer, and installer agree. However, the resulting assembly will NOT be
protected from wind driven rain. Insects and other foreign matter may also access these openings.
If closures are installed, drive panel fasteners through the closures orjust above the closures.
Ridges
The top of the roof, or the ridge, is made watertight with a ridge cap.
There are a variety of styles, sizes, and method of attachment, but
the concept is the same. Butyl tape (or sealant) and foam closures are
recommended to provide watertightness and protect against wind
driven rain. Ventilated closures are available for most panels and
should be used if ventilation is desired.
4"overlap (minimum) recommended in Florida. 1"overlap
in other locations. Sealant (caulk or butyl) to seal the laps is
recommended, but not required.
Drive fasteners with sealing washers through both sides of the ridge cap and into the roof deck. Use fasteners
which are long enough to reach the roof deck or structure below the panel and match the fastener spacing
used for the panel at the ridge. It is typically best to fasten through the panel rib to avoid deforming the ridge
cap.
Closures may be omitted if owner, designer, and installer agree. However, the resulting assembly will NOT be
protected from wind driven rain. Insects and other foreign matter may also access these openings.
If closures are installed, drive ridge cap fasteners through the closures orjust above the closures.
Box off the end of the ridge cap and use sealant and rivets as needed to secure.
Vented closures are available for most panel types and may be used in place of traditional closures.
Hips
Hips are similar to ridges, in that it is a high point where panels meet. Where hips differ is that a hip is sloped while
a ridge typically maintains a constant elevation. Hips are made watertight with ridge cap as described and shown
above, with the following additional notes:
Vented closures are not recommended for hips unless the ventilation design prescribes it. Ventilation design
typically recommends that exhaust points be located at the same elevation.
Hip closure tape (e.g. "Peel and Seal") may be used in place of other closure methods.
Install from eave to ridge (bottom to top) so that runoff does not feed into an overlap.

The following excerpts are from the 2017 Florida Building Code (FBC), which is publically available here:
https:/Icodes.iccsafe.org/public/collections/FL.
These excerpts are provided as a courtesy reference only, always consult the local building department and a
complete copy of the applicable building codes.
Key Requirements:
Underlayment shall be installed, and shall have an approved HVHZ product approval or Miami -Dade Notice of
Acceptance (NOA). (Per requirements ofTAS 100 testing.)
Roof deck shall meet the requirements of PS1, PS2, or ANSI/APA PRP 210. (FBC 2303.1.4)
Maximum on center fastener spacing perpendicular to rib shall be 12" in the field and 8"at the ends of a panel.
Maximum on center fastener spacing parallel to rib shall be 12"These spacing supersede the values listed in
the load tables. (FBC 2222.4.2, 2222.5.1)
Fastening shall be sufficient to provide resistance for lateral movement as required by rational analysis. Note
that in most cases the roofing deck should be designed to provide all necessary lateral resistance; diaphragm
design is excluded from Gulf Coast product approvals.
Edge metal and flashing shall be installed in accordance with RAS 111. (FBC 1514.4.2)
Minimum slope:2:12. (FBC 1515.2.2)
FBC 2222.4.2 Structural Sheets

2222.3.1 and as required by rational analysis, and/or tests, but not less frequently than the following maximum
spacing:
1. One fastener shall be placed near the corner of each sheet or at overlapping corners of sheets.
2. Along each supporting member, the spacing of fasteners shall not exceed 8-inches (203 mm) on centers at
ends of sheets or 12-inches (305 mm) on center.
3. The spacing of edge fasteners between panels, and between panels and supporting members, parallel to the
direction of span, where continuous interlock is not otherwise provided shall be not more than 12-inches (305
mm) on center.
4. Fastening shall be by bolting, welding, or other approved fastening device that provides a resistance to lateral
movement as required by rational analysis or by test, but not less than 400 pounds per lineal foot (5838 N/m).
FBC 1514.2 Flashings
All roof flashing and terminations shall be designed and installed to resist the windload requirements of Chapter
16 (High -Velocity Hurricane Zone) of this code, and shall be in compliance with the provisions set forth in RAS 111.
Gables
The open sides of a roof, or gable ends, are protected with gable trim.
There is a variety of styles, sizes, and methods of attachments, but two
primary designs. An eave drip (or similar) can be installed underneath
the panels, or a gable rake (or similai)can—be installed over the panels.
In either case, the use of butyl tape or sealant is recommended to
ensure a watertight seal between the roof panel and the trim. Fascia is
recommended to fully protect the structural member.
4"overlap (minimum) recommended in Florida. 1"overlap in other
locations. Sealant (caulk or butyl) to seal the laps is recommended,
but not required.
Install from eave to ridge (bottom to top) so that runoff does not feed into an overlap.
Fasten into the panel/roof deck and into the exposed face on the gable side with the same panel fastener
spacing used along the gable. Use fasteners with sealing washers.
Box off the end of the gable and use sealant and rivets as needed to secure.
If an eave drip trim is used underneath the panel vice the gable rake trim over the panel, the fastener in the
exposed face on the gable is optional. Follow the eave requirements described previously.
Valleys
Valleys are low points where two slopes meet. Valleys are high risk
areas for leaks, and must be carefully flashed and installed. Valley
trim is installed before the panels so that the panels can overlap and
provide an uninterrupted drainage plane.
12"overlap (minimum). Sealant (caulk or butyl tape) to seal the
laps is required.
Expanding foam and sealant (caulk or butyl) is required to seal the
exposed ribs.
Install from eave to ridge (bottom to top) so that runoff does not
feed into an overlap.
The valley should be designed to keep the depth of water from the design rain storm from flooding the ribs.
Transitions
Some roof designs will include roof sections at different slopes. Where
these slope changes occur, install a transition trim. Working from
bottom to top, install the lower panels followed by the transition
trim.The transition trim will overlap the lower panels and underlap
the upper panels to provide a continuous drainage path. Use of butyl
tape (or sealant) and foam closures is recommended to provide a
watertight connection and to protect against wind driven rain. The
upper panels are installed over the transition trim to complete the
uninterrupted drainage plane.
A gambrel style roof may change slopes several times, with steeper slopes on the lower sections of the roof. Install
gambrel flashing in the same manner as a typical transition trim.
4"overlap (minimum) recommended in Florida. 1"overlap in other locations. Sealant (caulk or butyl tape) to
seal the laps is recommended but not required.
(888) 393-0335 1 www.gulfcoastsupply.com M
(888) 393-0335 1 www.gulfcoastsupply.com
Closures may be omitted if owner, designer, and installer agree. However, the resulting assembly will NOT be
protected from wind driven rain.
If closures are installed, drive fasteners through the closures.
Use fasteners with sealing washers on both sides of the transition flashing and matching the panel fastener
spacing.
Install from eave to ridge (bottom to top) so that runoff does not feed into an overlap.
Walls
Where the peak of a roof section meets a wall instead of a ridge, an
end wall trim is used. As with most trims, many different styles, sizes,
and methods can be employed. The use of butyl tape (or sealant) and
foam closures is recommended to provide a watertight system and to
protect against wind driven rain.
Similar to the end wall trim, when the side of a roof section meets a
wall instead of a hip or a gable, a side wall trim is used. Side wall trim is
installed similarly to the end wall.
4"overlap (minimum) recommended in Florida. 1"overlap in
other locations. Sealant (caulk or butyl tape) to seal the laps is
recommended but not required.
Closures/butyl may be omitted if owner, designer, and installer
agree. However, the resulting assembly will NOT be protected
from wind driven rain.
If closures/butyl are installed, drive fasteners through the closures/
butyl.
Use fasteners with sealing washers for attachment through panels.
If fasteners attaching the wall trim to the wall are exposed, use
fasteners with sealing washers and match the panel fastening
pattern along the wall. If the fasteners will be covered by siding, low profile fasteners may be used.
Install from eave to ridge (bottom to top) so that runoff does not feed into an overlap.
Box off the end of the side wall or endwall trim and use sealant and rivets as needed to secure.
There are a number of wall flashing options —two additional methods are shown below.
manufacturer's installation instructions.
3. The minimum slope for standing seam of roof systems shall be one -quarter unit vertical in 12 units horizontal
(2-percent slope).
FBC 1507.4.4 Attachment

Roof Penetrations
Since penetrations are literally holes in the roof, and since holes in
the roof cause leaks, it is of critical importance that all penetrations
be properly flashed and sealed. Pipe boots are recommended for
pipes (e.g.-Tent-stacks), and shouldbe-insta-iled as shown. Install pipe
boots with a continuous bead of sealant and fasteners at least every
1"as needed to ensure a complete seal. Skylights and chimneys are
installed with a combination of end wall and side wall trims as shown.
Large penetrations (greater than 30"in width) typically require a
structure called a cricket to divert water around the penetration.
Use sidewall flashing on the sides, endwall on the downhill side, and typically a chimney flashing on the uphill
side. Construct from the downhill side working up so that all laps provide a continuous drainage path.
Use closures and butyl (or similar sealant) to ensure watertight connections between all metal components.
Choose pipe Slide over pipe Form to roof profile Apply sealant Fasten to complete
opening and trim
Panel Laps
Gulf Coast recommends using full length panels, with a single panel running from ridge to eave. When this is not
possible, the ends must be lapped a minimum of 12" and sealed completely with sealant or butyl tape.

Gulf Coast Supply maintains load tables for each product in various installation conditions. These load tables
indicate the fastening requirements for the roof zones and wind speeds shown. Because building design and site
considerations impact the wind load and response characteristics, these tables only consider a generic "typical"
installation. These tables ONLY APPLY when the indicated requirements are met. Refer to each load table for the
specific requirements.
If unique considerations exist beyond the scope of this load table, the services of a design professional may be
required. Subject to additional site -specific design fees, Gulf Coast Supply & Manufacturing is able to complete
most engineering services required or to refer a third -party design engineer.
How to use the load tables:
If the intended installation meets the requirements listed, the tables provide a prescriptive design basis for
selecting the appropriate fastener pattern and fastener spacing. Follow these steps to properly apply the load
tables:
1. Determine wind speeds. Check with the local building department to determine if the municipality has
adopted a wind speed requirement. Some municipalities permit the use of windspeed.atcouncil.org. If a
wind speed is not prescribed, there are tables in ASCE 7 and the Florida Building Code which can be used
to determine the design wind speed (see next few pages). Furthermore, some project specifications may
stipulate a different requirement. Be sure to check all applicable sources.
2. Select the page for the appropriate panel profile.
3. Find the material (e.g. 24ga/26ga/29ga steel) and the substrate (e.g. plywood, 1x4 purlins, OSB, steel deck, or
steel/wood framing) being considered.
4. Find the wind speed column for the selected material and substrate; note the fastener pattern for each zone.
5. Use the roof layout images to determine the location and extent of zones 1, 2, and 3.
6. Reference the fastener pattern images to determine the fastening details. Install the roofing panels in each
zone with the required fastener pattern and spacing.
Notes:
Fastener spacings shown are the maximum allowable spacings. Use of reduced spacing (i.e. installing more
fasteners) is acceptable and meets the intent of these load tables.
Material thicknesses are minimum values. Use of thicker material (e.g. using 26ga instead of 29ga or using
0.040 when the table lists 0.032) is acceptable and meets the intent of these load tables.
Fasteners listed are minimum diameter fasteners. Larger diameter fasteners are acceptable and meet the
intent of these load tables.
A dashed line indicates that the panel and substrate selected is NOT suitable for installation in that wind zone.
For exposure D locations, please refer to Appendix C.
Methodology:
Uplift requirements are calculated using method 1 in ASCE 7-10.
Design uplifts are calculated from uplift requirements using ASD load combinations. No downward loads are
considered as counteracting the design uplift.
Panel rated uplift capacities are reduced by factors of safety as required by FBC.
The de -rated panel capacities are compared to the ASD design uplifts calculated.

All exposed fastener systems are approved for installation over an existing single layer of shingles, provided that
the following requirements are met:
a. Five -fold criteria of FBC 1511.3 or FBC Residential R908.3 must be satisfied.
b. Fastener penetration into roof deck and/or purlins is unchanged (use longerfasteners as required).
c. Product must be installed in accordance with manufacturer's recommendation, all applicable building
codes, and the conditions of the applicable FPA.
d. Installation shall be over 1x4 battens (or similar), or over any code -approved underlayment. Metal panels
shall NOT be installed in direct contact with existing shingles.
1 X4's may either be nailed to the roof deck or screwed directly into the roof truss or rafter as noted below.
Attachment, shalI be as prescribed below.The truss/rafter connection is designed to meet exception 1 in FBC
1511.3, and transmits the roof load directly to the buildings structural system without relying on the existing roof
or roof covering for support.
Note that for 1x4 purlins on OSB decking, the 1x4 must be fastened directly to the roof truss or rafter. In all other
cases, 1x4 purlins shall be fastened to the deck.

Panel Uplift Ratings
Each panel has been tested
to TAS 125, UL580/1-11-1897,
and/or ASTM E1592 in the
various fastener patterns and
substrates shown in the table.
These ultimate uplift values
are reduced by a factor of
safety of 2.0 or as required by
the Florida Building Code.
For projects where the
wind uplift calculations
have been. completed for
a specific project, compare
the ASD/allowable design
uplift pressures to the panel
capacity uplifts shown. (Note
that the rated panel uplifts
are reduced by a factor of
safety of 2.0 or as required
by FBC—therefore these
panel capacity values may
be compared to the ASD/
allowable design uplift
pressures.)
Refer to Appendix A for 1 x4
attachment requirements.
