Installation Instructions
Building Design and Construction
In order to ensure the anticipated performance and longevity,
protect metal panels from potentially corrosive situations and materials.
When treated lumber will be in direct contact with metal panels or flashings please note the following: Galvanized steel is compatible with the
CCA (Chromated Copper Arsenate) pressure-treated lumber that was
predominantly used before 2004, but not with the older Penta treated
lumber or the new ACQ (Alkaline Copper Quartenary), CA (Copper
Azole), or CBA (Copper Boron Azole). Stainless steel or other special
treated fasteners should be used into these non-compatible pressure
treated lumbers. Aluminum must be separated from contact with all
treated wood since the soluble copper in the preservative is corrosive to
aluminum. Likewise, dissimilar metals also require a protective barrier
between them to prevent galvanic corrosion. Request FABRAL Technical Bulletins #803, 106, and 107 for more information on treated lumber
and dissimilar metals.
Plastic, builders’ felt, bituminous paint, caulking, or gasket material may be used to separate panels from treated wood
and dissimilar metals. When using aluminum panels in direct contact
with steel, use a separator as described above and fasten with Stainless Steel screws.
Fertilizer, lime, acids, feeds, manure, soils, and many other
compounds also cause corrosion in metal panels. Contact between
metal panels and any potentially corrosive materials should be prevented.
Porous insulation materials may absorb and retain moisture,
and should not be used in direct contact with metal panels. Use a vapor
barrier such as polyethylene plastic or 30-lb felt to prevent moisture
from contacting both the insulation and the metal panel.
FABRAL’s translucent panels are intended for siding applications only. In all situations, foot traffic should be avoided on translucent
panels. Translucent panels used in roofing applications will break down
in a short time and cause staining and premature corrosion of the metal
panels below. If used on roofs, apply butyl caulking to separate the
fiberglass panels from the metal. Translucent panels should be cleaned
and sealed regularly, as recommended by the translucent panel manufacturer.
Purlins, Girts and Roof Deck
The substructure to which the metal panels are fastened must
be properly spaced and sufficiently thick to provide a roof or wall system
able to meet required design loads.
A 2” nominal lumber thickness provides the maximum pullout
values for both screws and nails
when the fasteners penetrate a
minimum of 1” into the wood. Since 1” nominal lumber and solid decking
are thinner, they provide somewhat lower pullout values. When using
purlins, FABRAL recommends a maximum spacing of 24” on-center
(note that 5V requires solid decking). Pullout values decrease if the
fasteners protrude completely through the purlins. Kiln-dried softwood
is recommended for purlins or decking (pine, fir, hemlock, and spruce).
Hardwoods are difficult to fasten into without splitting and contain tannic
acids that are corrosive to metal panels. Green (non-kiln-dried) lumber
may warp, twist, and shrink as the wood seasons fully, causing waviness in the panels as well as loosening and leaking of the fasteners.
Solid decking is highly recommended for all residential applications. When usingsolid decking or sheathing, always use 30-lb felt
or underlayment and plan on using closer

fastener spacing and larger diameter #14 screws. (Refer to the tables
on page 31).
On re-roofing projects where the condition of the old decking
is in question, or where existing shingles will be left in place, new 2x4
purlins should be fastened through the decking and into the rafters. This
will provide a solid framework for attaching the metal panels. For more
detailed information on Re-roofing applications, consult FABRAL Technical Bulletin #721, Re-Roofing With Metal. Load tables are available for
all FABRAL panels; contact FABRAL for additional information.
Roofing

Panel sidelaps should face away from wind driven rain. To
accomplish this, begin by installing the first sheet square with the
eave and gable at the down wind end of the roof, farthest away from
the source of prevailing winds.
In applications requiring a panel endlap, please refer to the
detailed instructions in this booklet. For best results, lap panels as
shown and install in the indicated sequence. All endlaps require sealant. When weather-tightness is critical, use sealant tape in all sidelaps.
To provide a drip edge, allow an overhang of 1 to 2 inches at
the eave. At the gable edge, use a gable or sidewall flashing. This will
keep weather out, prevent lifting in high winds, and provide a neat, finished appearance. The trim and roofing sheet should be fastened every
12 to 24 inches along the gable edge.
Roof Pitch
The metal roofing panels shown in this manual require a minimum slope of 2½” per foot to ensure proper drainage. Refer to the raincarrying table in this booklet for the maximum allowable panel length per
slope that will provide adequate drainage. For longer slopes and lower
roof pitches, contact FABRAL for other suitable profiles.
Bending and Bowing
Aluminum roofing and siding sheets are rollformed from hardened, tempered metal for maximum strength. If a sheet must be bent,
a gentle 90-degree bend is the maximum recommended. Metal should
not be re-bent once it has been formed, nor should it be folded back on
itself. When a metal roofing sheet must be installed on a curved roof,
screws should be installed at every overlapping rib at the sheet ends
to resist the natural tendency of the metal to spring back. The standard
fastening pattern is permitted over the rest of the sheet. When installing
the metal panels shown in this booklet over a curved arch, the minimum
radius of the arch is 18’ for aluminum panels and 24’ for steel panels.
Use sealant tape or butyl caulking at all sidelaps and endlaps.
Additional care and fasteners must be provided when securing the top
and bottom purlins on an arched rafter building to prevent the curved
panels from pulling the purlins loose from the rafters. Ring-shank pole
barn nails, heavy wood screws, lag screws, or bolts are often used for
attaching these purlins.
Siding

Siding should be installed using the standard fastening and
overlap patterns to ensure optimum performance. For strong, neat corners use hemmed corner flashings. Do not run siding sheets all the
way to the ground. Instead, provide a protective base of concrete,
masonry, treated wood, or similar material and terminate the siding
sheets 6” above grade.

Installation Instructions
If siding sheets are installed horizontally, use sealant tape or
butyl caulking at the vertical laps to ensure weather-tight joints. Install
panels from the bottom up so that water is directed away from, and not
into, the lap joints.

Refer to the SMACNA Architectural Sheet Metal Manual
for additional information about detailing and installing
flashings.

Fastening
FABRAL can supply either screws or nails for fastening into
dimension lumber, with screws offering better pullout values. Always
use screws with solid sheathing. Screws for use with steel panels are
galvanized and then coated with an organic polymer for optimum corrosion resistance. For best results with aluminum panels, use #300
series stainless steel screws.
The FabrOseal® galvanized ring-shank nail, with its premium
long-life silicone rubber gasket, assures a lasting seal and is the best
nail available for steel panels when screws are not desired.
The correct way to fasten steel panels with nails is to drive
the nail through the top of the rib so the washer is compressed securely
against the metal. Nail placement must be in the ribs for roofing applications to minimize the potential for roof leaks. Over-driving the nail
can split the washer and dimple the metal, causing leaks.

Always work safely when installing metal products and use
extreme caution on the roof at all times. Wear gloves and safety glasses to reduce the risk of injury, and use hearing protection when operating power tools. Always be sure that ladders are safely positioned and
properly secured. Safety harnesses or other special equipment may
be required; be sure to Consult OSHA guidelines for compliance with
all safety requirements.
Do Not walk on panels until all the fasteners are installed.
Metal roofing panels are slippery when wet, dusty, frosty, or oily -- Do
Not attempt to walk on a metal roof under these conditions. Wear softsoled shoes to improve traction and to minimize damage to the paint
finish. Always be aware of your position on the roof relative to any roof
openings, roof edges, co-workers, and penetrations. Installing metal
panels or flashings on a windy day can be dangerous and should be
avoided if possible.

Correct

Under-Driven

Over-Driven

Wood screws with combination metal and neoprene washers
should be installed in the flat area of the panel adjacent to the ribs, and
tightened such that the washer is compressed as illustrated above. This
will ensure a lasting, leak-proof seal. Remove any metal filings created
by the drilling action of the screws to avoid rust staining on the panel
surface. Refer to the fastening schedules in this booklet for the correct
fastener locations.
Flashing and Trim
Always begin flashing installation from the bottom and work
up, so that upper flashings are lapped on top of lower flashings. This will
prevent moisture from leaking under the flashings and into the structure.
Endlap flashings a minimum of 6” and seal the lap joints with sealant.
Extend flashings 4-6” beyond the building, cut along the bend lines, apply sealant, and fold the side flaps in and the top flaps down to cap off
the ends. Secure with pop-rivets or stitch screws.
Some roof conditions, such as valleys, may require a longer
endlap and/or a larger flashing to properly drain moisture from the roof.
Factors that influence flashing size, shape, and endlap requirements
include roof pitch, roof geometry, slope length, and climatic factors (such
as heavy snowfall or rainfall).
Whenever possible, begin trim installation at the downwind
end of the roof, farthest away from the source of prevailing winds, to allow flashing laps to face away from wind-driven rain. Refer to the details
in this book for the proper location of fasteners and sealants.
The flashings and trims shown in this book are standard parts.
Custom trims are available to meet your specific design needs. If you
need a special trim, please furnish a drawing of the desired shape, including dimensions and angles, to your Fabral dealer to obtain pricing
and availability.

Safety

Cutting Aluminum Panels
To make a cut parallel to the ribs, score the panel deeply with
a sharp utility knife and bend back-and-forth along the score, breaking
the metal off cleanly. For cuts across the ribs, use straight-cut snips,
electric or pneumatic shears, a portable profile shear, or an electric
nibbler. Some installers prefer using a circular saw with a metal cutting
blade (a fine-tooth hardwood blade, or a standard combination blade
reversed in the saw works also). Light oil or soap on the blade will
make cutting easier.
Cutting and Drilling Steel Panels
Steel panels may be cut with metal snips, electric or pneumatic shears, a portable profile shear, or an electric nibbler. Some
installers prefer using a circular saw to cut metal panels. Do Not use
self-consuming abrasive blades because of the following: 1. Abrasive
blades burn the paint and galvanizing at the cut edge, leaving edges that are jagged and unsightly and rust more quickly 2. Abrasive
blades produce hot metal filings that embed in the paint and cause rust
marks on the face of the panel 3. All saw cut panels must be turned
face down and cut in a location down-wind and well away from the
building and other panels to avoid embedment of metal filings on other
panels 4. All saw cut panels must be thoroughly wiped to ensure the
removal of all metal filings. If saw cutting cannot be avoided, select a
carbide-tipped blade specially designed for cutting light-gage ferrous
metal panels. These blades are now available at many home centers
and lumber yards. Pre-drilling wall panels gives uniform alignment of
screw rows. Be sure to remove drill filings once panels are installed to
avoid rust marks from the filings.
Building Maintenance
A metal roof should be inspected annually and cleaned as necessary
to maintain its beauty and performance. Any debris or residue, including leaves, twigs, and dust should be cleaned off promptly to prevent
moisture entrapment against the metal, which may lead to finish deterioration or premature corrosion. Flashings may need to be re-sealed
periodically in order to maintain optimum weathertightness.

PERFORMANCE GUARANTEE
Fabral, a Euramax Company, Lancaster, PA, hereinafter referred to as "Fabral" or "Seller," guarantees that within the continental United States
normal outdoor atmospheric conditions (which term excludes corrosive or aggressive atmospheres including, but not limited to those contaminated
TM
with chemical fumes or salt spray) will not cause the exterior side paint on the ENDURACOTE galvanized steel roofing and siding panels sold to
you under this guarantee to:

Example Warranty Form
Other Warranties

1. Crack, check, or peel for the lifetime of the building for sidewall panels and roofing panels.
NOTE: A crack is a break in the coating sufficiently deep that the underlying surface is visible. Checking refers to shallow breaks in the coating
which do not expose the underlying surface. Peeling occurs when the coating actually comes off the metal in pieces. Slight crazing or cracking
may occur on roll formed edges or break bends at the time of forming and should be considered as standard and shall not constitute a basis for
complaint under this warranty. However, the film will not lose adhesion to the substrate when cellophane tape applied at the bend is removed.
2. Chalk in excess of a numerical rating of eight (8) for vertical siding panels or a numerical rating of six (6) for roofing and non-vertical siding
panels for a period of thirty (30) years when measured in accordance with the standard procedure specified in ASTM D-4214 (latest).
NOTE: Chalk refers to the formation of loose, removable powder evolved from the coating itself upon breakdown of its resin or binder. The test
merely utilizes dark or light colored felt rubbed against the surface to pick up a measurable amount of the chalk which is then compared to a
standard. On a scale of 10 (best) to 0 (worst), a rating of eight is considered a moderate amount of chalk, while a rating of two would represent
extreme chalk.
3. Fade or change in color in excess of five (5) units of color difference (Hunter ¨E units) for vertical siding panels or in excess of seven (7) units of
color difference (Hunter ¨E units) for roofing and non-vertical siding panels for a period of thirty (30) years when measured in accordance with the
standard procedure specified in ASTM D-2244 (latest) paragraph 4.3, on a washed test area.
NOTE: Most coated surfaces, when exposed to the sun, will fade to some degree over a period of time. Five Hunter ¨E units is a noticeable, but
not usually objectionable, degree of color change. Colors may also darken or change hue rather than fade, particularly on exposure in polluted
environments. The Hunter ¨E units are intended to apply to color change in either direction in comparison with the original or unexposed color. It is
understood that fading or color change may not be in uniform if the surfaces are not equally exposed to the sun and elements.
For purposes of determining whether an exposed coated panel meets the standards set forth in above paragraph, all chalk, dirt and other film
deposits on the area of the panel to be tested for color must be removed by washing prior to evaluation.
To wash test area, use a pad of 28/24 mesh cheesecloth and distilled water with mild soap or detergent cleaner. Wet the cheesecloth thoroughly
with the solution and rub it, using moderate hand pressure, over an area of panel approximately 4" x 4". Care must be taken to avoid any
scratching, burnishing or other physical alteration of the coating surface. After washing as described above, flush off the test area with distilled
water and allow to air dry in a vertical position.

4. Exhibit accumulations of red rust caused by acid rain on non-vertical installations of Enduracote painted panels for a period of ten (10) years
quantities that result in discoloration clearly visible in casual observation, except that this provision shall not apply to any accumulation of red rust
which occurs within one-half inch of any portion of the coated surface which is cut or penetrated at any time after application of the pretreatment and
paint system to the substrate.
TERMS AND CONDITIONS
1. DURATION OF WARRANTY
The paint coating of Fabral roofing and siding panels is guaranteed to perform in the manner described above for the lifetime of the structure for
crack, check, or peel, or 30 years for chalk and fade, or 10 years for red rust, from the date such panels are installed by Buyer, provided installation
occurs within six months from the date of application of coating by Seller's coating facility. In no event shall the guarantee extend beyond 30 years
and 6 months for chalk and fade, or 10 years and 6 months for red rust, from the date of application of coating by Seller's coating facility.

The Energy Star® Program
The Energy Star Program promotes highly reflective roof systems that reflect
solar energy. These roof systems allow buildings to stay cooler and, in turn,
use less electricity for air conditioning; less electricity means a reduction in
power generation and a reduction of pollutants discharged at power plants.
Fabral has attained Energy Star approval for many of its Enduracote™ system colors. Ask for Technical Bulletin #724 titled “Energy Star Approval”, for
program details and a list of approved Enduracote™ colors.

Post Frame Estimating & Roof Types
Estimating Metal Roofing, Siding & Flashings
Panel lengths are to be determined by the truss top chord
or actual field measurements. Remember to add for overhangs at the eaves; subtract for a gap at the ridge. Siding should be kept up away from the ground with a skirt
board.
Number of Panels
The coverage of the panel being used will determine the
number of panels at a length (i.e.: 3’ coverage panel on a
30 ft. long building would require 10 panels on each side of
the ridge or 20 panels at the particular length.)

Gambrel Roof

Horizontal Measurment to a Roof
Divide the building width in half, then multiply by the slope
factor (i.e.: 40’ wide building with 4/12 slope. 40 divided
by 2 equals 20’ times 1.054 equals 21’-1” in slope dimension.) Allow for 1/2” to 1” gap at peak and 1” to 2” eave
overhang.

Notes For Rain-Carrying Tables

1. All values based on a 1-hour duration storm of 4"/hr. intensity.
2. Values represent the point at which the panel ribs will flood.
3. Size and frequency of penetrations can greatly reduce the amount of water removed from a rooof.
4. All panel endlaps must be caulked.
5. When weather-tightness is crtical, use sealant tape in all sidelaps.

Basics for Residential Installation
1.

Determine the thickness and type of substrate to be used to support the metal roofing.

Solid decking is highly recommended for all resdiential applications (i.e.,
plywood, OSB).
2.

Refer to the Load-Span tables to select the proper fastener and spacing to meet loads on your
structure.

Nails are NOT recommended for residential applications.
3.

Consult local building codes and restrictions to determine acceptable methods of construction
for residential applications in your area.

Solid decking with 30# felt or Pro Master® underlayment for residential applications is recom-
mended. Ice & water shield or similar self-adhesive membrane is recommended at all valleys,
dormers, chimneys, transitions, skylights and other critical areas.

When re-roofing with metal panels over an existing shingle roof, 2x4 purlins or 1x4 furring
strips run parallel with the ridge of the roof and must be securely fastened into the roof rafters
or trusses.

Request Fabral’s technical bulletins # 720 and # 721 for more details on residential roofing.
