Light Gauge Metal Roof and Wall Panels
Installation Guide for Delta Rib™, Delta Rib™III, Nor-Clad®, Strata Rib®& 2½Corrugated
In addition to weather tightness, long life, good looks
and economy, ASC Building Product’s Light Gauge Roof
and Wall Panels are designed with ease of installation
as a primary consideration. This guide is intended to
help the installer achieve a high level of quality in the
finished product. Please do not hesitate to contact an
ASC Building Products representative for assistance.
Important Notice
Be sure to read this manual in its entirety before
beginning installation.
This manual is provided to the customers of ASC Building
Products as a guide to assist in the installation of Light
Gauge Metal Roof and Wall Panels. Use for any other
purpose is prohibited. This manual remains the property of
ASC Building Products.
These instructions contain suggested application
procedures only and cannot replace the need for good
common sense and experience. Responsibility for
conformance to state and local building codes, as well as
any other applicable project requirements rests with the
installer, as does the responsibility to observe reasonable
safety procedures.
ASC Building Products assumes no responsibility for
any problems which might arise as a result of improper
installation or any personal injury or property damage that
may occur with the product’s use.
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:
1⁄16"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.
Blind Rivet Hand Tool:
Used for miscellaneous flashing and trim applications.
Marking Tools:
Indelible markers, pencils, or scratching tools.
Minimum Recommended Tools
& Equipment
Note:
• It is recommended that Light Gauge Roofing be applied
on roofs with a minimum slope of 3 inches per foot (3:12).
* The details contained in this guide are shown over a ply-
wood substrate. Details remain the same for either a solid
substrate (plywood or steel), spaced framing or intermit-
tent support condition with only the fastener type chang-
ing. Where spaced framing is used, perimeter supports
for flashings must be considered.
** Each flashing part in this guide has been assigned a part
number. Each part number contains one or two letters
followed by one or two numbers, for example: (EW17).
These part numbers have been provided for you to make
ordering these flashing parts quick and easy.

Minimum Recommended Tools & Equipment (Con’t)
Scratch Awl:
Used to mark the steel.
Utility Knife:
Used for miscellaneous cutting.
Electric Drill:
Used to drill holes such as those required for rivet
installation.
String Line:
Used for general alignment and measuring.
Tape Measure:
25 foot minimum (another 50 ft. is handy).
Locking Pliers:
Standard and “Duckbill” style for miscellaneous clamping
and bending of parts.
Delivery, Handling and Storage
• Always check the shipment upon delivery. Check
for damage and check material quantities against
the shipping list. Note any damaged material or
shortages at the time of delivery.
• Handle panel bundles and individual panels with
care to avoid damage. Longer bundles and panels
may require two or more “pick points” properly
spaced to avoid damage that can result from
buckling and/or bending of the panels. Request a
copy of the Long Length Handling Instructions and
diagrams from ASC Building Products customer
service as required.
• Store the panels and other materials in a dry, well
ventilated area and away from traffic. Elevate one
end of the bundle so that any moisture that may
have accumulated during shipping can run off. Be
sure that air will be able to circulate freely around
the bundles to avoid the build-up of moisture. Never
store materials in direct contact with the ground.
• Wear clean cotton gloves when handling unpainted
ZINCALUME®-coated panels or flashings to avoid
discoloration. Rollforming die marks (which appear
black), particularly at bends, will be visible.
• Wear clean, non-marking, soft soled shoes when
walking on the panels to avoid shoe marks or
damage to the finish. Do not step on the panel
seams or ribs. Step only in the flat area of the panel.
Safety Considerations
• Never use unsecured or partially installed
panels as a working platform.
Do not walk on panels until they are in place on the
roof and all of the fasteners attaching the panels to
the roof have been installed.
• Metal roofing panels are slippery when
wet, dusty, frosty or oily.
Do not walk on a metal roof when any of these
conditions are present. Wearing soft soled shoes will
help minimize slipping and help prevent damage to
the painted surfaces.
• Do not walk on the panel seams or
major ribs.
When walking on the fully installed roof panels, be
sure to step only in the flat areas of the panels.
• Always be aware of your position on the
roof relative to your surroundings.
Take note of the locations of roof openings, roof
edges, equipment, co-workers, etc.
• Always wear proper clothing and
safety attire.
Wear proper clothing when working with sheet
metal in order to minimize the potential for cuts,
abrasions, and other injuries. ASC Building Products
recommends safety glasses and gloves.
• Use care when operating electrical and
other power equipment.
Observe all manufacturer’s safety recommendations.
• Roof installation on windy or stormy days
can be dangerous.
Avoid working with sheet metal products on windy
or stormy days.

Light Gauge Metal Roof and Wall Panels
Installation Guide for Delta Rib™, Delta Rib™III, Nor-Clad®, Strata Rib®& 2½Corrugated
Roof Preparation
ASC’s Light Gauge Roofing can be used in both
new construction and retrofit roofing applications. We
recommend the installation of Light Gauge Roofing over
a continuous rigid substrate such as plywood, wood
decking, or over intermittent supports. Contact ASC for
additional information.
The following steps need to be taken to prepare the roof
for installation of Light Gauge Roofing panels:
New Roofs:
1. Make sure there are no nails or other objects
protruding from the substrates that might puncture the
underlayment or the roof panels. Clean all debris from
the roof.
2. Check all details for possible roof penetrations
which must be added to the deck prior to roof panel
installation.
3. Cover the entire roof deck with a minimum of 30
lb asphalt-saturated felt paper. Some synthetic
underlayments may be used in place of felt with our
roofing. Installer must ensure they meet the minimum
standards of 30 lb felt and that the manufacturer
has approved them for use with metal roofing. For
applications over spaced framing other types of
moisture barriers may be required. Begin at the eave
and roll the felt horizontally (parallel to the eave).
Allow each consecutive course to overlap the previous
one 3 inches. Overlap the end a minimum of 6" when
starting a new roll of felt. Areas of felt paper that have
been torn or cut should be replaced or repaired prior
to installation of the metal roof. (See illustration #1).
4. Place an alignment line along the gable end where
the first roof panel will be installed. This line must
be parallel to the gable edge of the roof deck
and square with the eave line. Check the roof for
squareness by making a 3' line across the eave. (See
illustration #2).
Completing the 3' x 4' x 5' triangle should place the 4'
edge of the triangle parallel with the gable. The first
roof panel will be placed parallel with this line. Slight
variations or out-of-square conditions up to 3" can be
covered by the gable trims shown on page 18.
5. It is very important to measure the entire length of
the roof from gable to gable. Correct placement
of the panels will allow the panel’s ribs on each
side to be covered by the gable flashing shown on
page 18. This will create a symmetrical appearance
on both gables. Should this be impractical, the
adjustable gable detail on page 29 can be used.

Note:
In areas where snow, ice, and heavy rain conditions exist,
a high temperature cold-applied rubberized underlayment
should be used in lieu of felt in the valleys. Felt on the
remainder of the roof will lap over the membrane where
the two meet. See Valley page 13.
Existing Roofing:
Some jurisdictions will allow reroofing over existing roofing
without the need for tearoff. Check with your local codes
or building department for your specific requirements.
For best results, Light Gauge Roofing requires a relatively
smooth and flat substrate. Application over rough and/or
uneven surfaces is not recommended, for example, wood
shingles.
If the roof is to be stripped down to the existing decking,
follow the procedures for new roofs on page 4. Be sure to
check the existing roof and repair any damaged areas prior
to installation of the new roof system.
Note:
Do not apply Light Gauge Roofing over roofs with
structural damage or trapped moisture.

ASC Building Products
A Division of ASC Profiles LLC
The following steps should be taken when installing
ASC’s Light Gauge Roofing over existing roofing:
1. Inspect the roof for damage and make the necessary
repairs to achieve a flat plane for the metal roof
panels. Wood shingles should be removed.
2. Secure any warped or loose roofing.
3. Make sure that there are no nails or other objects
protruding from the roof that might puncture the new
underlayment or the new roof panels.
4. Remove all moss and other debris from the roof.
5. Cut off any overhanging roofing flush with the roof
deck and remove all hips, ridge caps, and penetration
flashings.
6. Metal debris/shavings should be removed from the
roof progressively and daily to prevent immediate
corrosion and scratching of the top coat.
7. Follow the directions on page 4, #2 through #5 on roof
preparation.

Notes
• The table above shows the Light Gauge panel fasteners provided by ASC Building
Products. Refer to the panel installation, flashing details, and fastener placement
pages of this manual for specific fastener usage. See page 6 for fastener spacing.
• Panel attachment screws must be long enough to penetrate through the roof decking
at least 3⁄8", or penetrate solid lumber at least one inch.
• All screws must be coated to provide protection against corrosion.
• Exposed fasteners should have sealing washers and be the same color as the parts
they attach.
• Roofing nails will also be required, but are not furnished by ASC. They are typically
used to temporarily hold a flashing in place that needs to be installed prior to panels.
• Screws must be properly driven to ensure proper seal and holding strength. Do not
under \drive or overdrive the screws. Recommended drill speed is 2000 rpm. Use of a
depth-sensing nosepiece will aid in properly driving screws.

GENERAL
Study the details section of this manual prior to the
installation of the panels. Pay close attention to
the following:
• Flashings that need to be installed prior to the
panels include Valley, Eave, Vented Eave,
Adjustable Gable and Chalet Gable.
• Apply sealant or mastic tape to the pre-installed
flashings as shown in the detail section of this
manual.

ILLUSTRATION #3
ILLUSTRATION #4
PROCEDURE
1. Install eave trim, valley trim and inside closure prior
to panel installation.
2. Align the edge of the first panel with the alignment
line constructed along the start gable. (See page 4
item 4 and illustration #3 below). Allow the panel to
overhang the eave 1" minimum.
3. Check the downhill end of the panel. If the panel
length is correct, the panel should overhang 1"
past the eave trim as shown below in illustration
#4. Also, the panel should not extend past the
centerline of the ridge. (See page 9)
4. After the first panel is properly aligned, fasten per
the fastener placement and spacing guidelines on
page 6.
5. Lay down the second and third panels, checking
alignment, making sure they are square. This will
ensure that a sawtooth effect at the eave and ridge
is avoided.
6. Metal debris/shavings should be removed from the
roof progressively and daily to prevent immediate
corrosion and scratching of the top coat.

Procedures
• Place a second layer of 36" roof felt in the valley
center line with 18" of roof felt on each side.
• Starting at the low end, trim and place the valley
flashing so it overhangs the eaves 1". (see page 14)
• Caulk and lap the subsequent valley flashings a
minimum of 8".
• Parallel to the valley, place two rows of 1⁄2" butyl
mastic tape sealant spaced as shown.
• The polyethylene closures cannot be installed diagonally
across a panel. At mitre cuts, use emseal closures at a
right angle to the panel ribs.
• Field cut the panels holding a minimum of 4" back
from the valley as shown. Larger valleys without
the center “V”, may be required in snow country
installations.
• Attach the panels to the roof and ‘thru-fasten’ along
the bottom end using a #14 x 1" woodscrew
at 8" up from the valley aligned with the second row of
butyl mastic tape.
• When valleys are required, install sidelap neoprene
mastic tape along the sidelap a minimum of 10'-0" up
from the panel edge.
Note: In areas where snow, ice and heavy rain con-
ditions exist, panels may need to be held back more
than 4" and the valley flashing overall width must be
increased. A high temperature cold-applied rubberized
underlayment should be used extending at least 3' up
from the center of the valley on each side.
