1.0 GENERAL
1.1 Purpose of the Installation Guide
This Installation Guide is provided to Alliance Steel,
Inc. (“Alliance”) customers and their erectors as the
recommended procedure for the correct assembly of the
AllianceLok 16 Roof System.
This guide is intended to be used in conjunction with the
project’s Erection Drawings to help plan and organize
the installation of the AllianceLok 16 Roof System. The
Erection Drawings identify the applicable roof conditions
and govern specic part arrangements. This Installation
Guide will help you identify parts, establish the installation
sequence, demonstrate correct assembly, and point out any
areas or procedures requiring special emphasis or attention.
This Installation Guide applies to the standard AllianceLok
16 Roof System. Custom roof conditions, including custom
details and instructions, will be covered by the Erection
Drawings. In case of conict between this Installation
Guide and the Erection Drawings, the Erection
Drawings will have precedence.
1.2 Customer’s Responsibility
The customer is responsible for proper installation of the
roof in accordance with the Erection Drawings and this
Installation Guide, and in accordance with good engineering
and construction practices.
The customer must take the responsibility for selecting
a competent erector, insist that the work be performed
by qualied and experienced standing seam metal roof
installers, insist that the erector take time to study and
understand this guide, then assure that the erector correctly
follows the guide’s instructions.
Alliance does not guarantee and is not liable for the quality
of erection. Alliance is not responsible for building defects
that may be attributed to improper erection or the negligence
of other parties.
Clarification concerning the AllianceLok 16 roof
installation should be directed to the Alliance Customer

GENERAL
1.3 Weather Tightness Warranty Requirements
(if applicable)
Depending upon the type of warranty, Alliance may
require the roof installer to be certied by the manufacturer.
Warranty requirements should be veried on contract with
Alliance.
Alliance must approve in writing all roof penetrations prior
to installation. This includes but is not limited to; Roof Curbs,
Vent Pipes, & Mechanical Equipment. Submittals should
be forwarded to Alliance for review.
It is the customers responsibility to coordinate warranty
inspections with the Alliance warranty department.
Any special applications with regards to the weather
tightness of this roof system should be brought to the
attention of the warranty department at Alliance.

2.0 SAFE ROOF INSTALLATION
2.1 Erector’s Responsibility
The erector of the roof system is responsible for the safe
execution of this Installation Guide. These instructions are
intended to describe the sequence and proper placement
of parts. They are not intended to prescribe comprehensive
safety procedures.
If the erector cannot safely assemble the roof in accordance
with these instructions, it is the responsibility of the erector
to stop the work and contact Alliance to determine alternate
assembly procedures.
2.2 OSHA
The Occupational Safety and Health Act (OSHA) has
promulgated many regulations applicable to the
installation of this or any other roof system. These
regulations, identied as Part 1926, Safety and Health
Regulations for Construction, are available from any
government bookstore. The objective of the OSHA
standards is to protect the worker from injury or illness.
These OSHA regulations should be recognized as job site
requirements and be fully complied with.
Failure to do so may result in substantial nes in the event
of an OSHA inspection. Safe installation practices may
be further dened and made mandatory by state or local
ordinances.
Maintaining good housekeeping on the jobsite is
recognized as being important to both OSHA compliance
and to successful job completion.
2.3 Walking & Working on Roof Panels
Do not walk on the last installed panel run, as the
unsecured edge could collapse under a person’s weight.
When installing clips or making endlap connections, etc.,
stand where the Roof Structural will support your weight.
An approved and safe walking platform should be used
in high trafc areas to prevent the Roof Panel from being
deformed, scratched, or scuffed.
A. PLACING PANELS ON THE STRUCTURE
Do not place bundles of panels on the Roof Structure
without rst verifying the structure will safely support the
concentrated weight of the panels and the weight of the
installation crew. Some Roof Structures may not be
designed to support the weight of a full panel bundle without
additional structure support.
B. WALKING ON ROOF PANELS
Do not use a Roof Panel as a working platform. An
unsecured panel could collapse under the weight of a
person standing between purlins or at the panel end.

2.0 SAFE ROOF INSTALLATION
2.3 Walking & Working on Roof Panels (Continued)
C. SAFETY EQUIPMENT
The use of safety equipment for the Roof Panel installation
is recommended at all times during the installation process.
However, when using lanyards, ensure that the clasp, belt
hooks and wire cables are covered in such a manner that
they will not scratch the panel surface if accidentally dragged
along the panel.
D. CREW SIZE
The length of the individual Roof Panels should be
considered when determining the crew size. It is
recommended that under normal conditions, there be
one person for every ten feet of panel length, plus one.
E. PANEL OVERHANG
Do not stand on the end of unsupported (cantilevered)
panels at the eave or ridge. Standing on the cantilever
portion may result in panel collapse.
F. POINT LOADS
When properly supported by the structurals, panels are
designed to support uniform loads, which are evenly
distributed over the panel surfaces. Point loads that occur
in small or concentrated areas, such as heavy equipment,
ladder or platform feet, etc., may cause panel deformation
or even panel collapse.
G. SLICK SURFACES
Panel surfaces and structural steel surfaces are hard,
smooth, and nonabsorbent, which causes these surfaces
to be very slick when wet or covered with snow or ice.
Even blowing sand or heavy dust can make these surfaces
difcult to walk on without slipping.
Unpainted panel surfaces are often coated with oil to
accommodate the panel-fabrication process. Although
designed to wash away or evaporate during normal weather,
the oil on new panels can be extremely slick, especially
during periods of light rain or dew.
Caution must be exercised to prevent slipping and falling
onto the roof surface or even sliding off the roof. Non-slip
footwear is a necessity and non-slip working platforms are
recommended.
H. ELECTRICAL CONDUCTANCE
Metal panels are excellent electrical conductors. A common
cause of injury is the contact of metal panels with power
lines during handling and installation. The location of all
power lines must be noted and, if possible, agged. The
installation process must be routed to avoid accidental
contact with all power lines and high voltage services and
equipment. All tools and power cords must be properly
insulated and grounded and the use of approved ground
fault circuit breakers is recommended.
I. FALSE SECURITY OF INSULATION
Blanket and board insulation blocks the installer’s view of
the ground below the roof. Serious injury can occur when
the installer gets a false sense of security because he
cannot see the ground and steps through the insulation.
J. SHARP EDGES
Some edges of panels and trim are razor sharp and can
cause severe cuts if proper protective hand gear is not
worn. Be careful not to injure others while moving panels
and trim.
2.4. Handling Roof Materials in Strong Winds
Do not attempt to move panels in strong winds. Wind
pressure can easily cause a man to lose balance and fall.
Strong wind uplift on a panel can lift the weight of the man
carrying the panel.
Loose, wind borne panels are very dangerous and can
cause severe injury and damage.
Secure stacks of panels with banding or tie-downs, so
wind will not blow the panels off the roof. Clamp individual
unsecured panels to the Roof Structurals. Clamp or block
panel bundles and accessory crates to prevent them from
sliding down the roof slope.

3.0 CHECKING THE STRUCTURE
3.1 Completed and Braced
Before placing materials and workers on the Roof
Structure to start roof installation, it must be conrmed that
the structure is designed to accommodate the material and
erection loads as well as the appropriate live loads and
wind uplift loads.
It also must be determined that the structure is complete
and structurally sound with all structural connections and
bracing in place and secure.
3.2 Lateral Stability
The sliding clip method of attaching the Roof Panels to the
Roof Structurals provides only limited lateral stability and
diaphragm bracing to the Roof Structurals.
Before placing materials on the roof and starting the roof
installation, conrm that the necessary roof bracing and
sag angles, strapping or bridging is in place and secured.
3.3 Alignment
Prior to installation, Roof Structurals should be checked
for overall dimensions and evenness of plane. The Roof
Structurals should also be checked to verify the roof system
can be installed without interference. Also, Roof Structurals
nearest the panel endlaps, ridge or high eave should be
checked for correct location to properly accommodate the
roof components.
A. TOLERANCES
To assure the roof system’s correct t-up and designed
weather tightness, the structure must be aligned within the
following tolerances:
Out of Square — The roof system can accommodate
1/8” of sawtooth of the Roof Panel ends at the eave, ridge
and panel splices. This means the allowable out of square
of the rake line relative to the eave line and ridge line is 1/2”
for each 10’ of rake run.
Structure Width and Eave Straightness — The roof
system is designed to accommodate ±2” of overall structure
width error, or ±1” of eave straightness error at each eave.
To assure that the accumulation of the structure width
error and eave straightness error does not exceed the roof
system’s tolerance, the structure width should be measured
from eave line to eave line at each rake, at the rst frame
line from each rake and at each point where there is a
signicant error or change in eave straightness (this usually
occurs at a frame line or at a wind column).
Structure Length and Rake Straightness — The roof
system is designed to accommodate ±2” of overall structure
length error, or ±1” of rake straightness error at each rake.
To assure that the accumulation of structure length error and
rake straightness error does not exceed the roof system’s
tolerance, the structure length should be measured from
rake line to rake line at each eave, at the ridge and at each
point where there is a signicant error or change in rake
straightness (this usually occurs at an end rafter splice).
B. MEASURING
Structure length and width may be measured with a
steel Measuring Tape from the face of the eave or rake
member to the face of the opposite eave or rake member.
The Measuring Tape must be parallel to the relative eave
or rake line and must be stretched taut.
Eave and rake straightness may be determined by
measuring deviations from a string line, which is stretched
taut along the eave or rake line.
C. AESTHETIC ACCEPTANCE
Although these structure alignment tolerances will allow for
reasonable roof component t-up and ease of installation,
the extremes of these tolerances may be aesthetically
objectionable and should be conrmed with the customer
before starting the roof installation.
D. CORRECTIONS
Any structure alignment error, which exceeds the above
stated tolerances, must be corrected before roof installa-
tion can begin. If it is decided that the structure alignment
errors cannot be corrected, alternate roof details may
have to be developed. The alternate details may require
additional materials, modied parts (with additional cost,
fabrication and delivery time) and additional installation
time. Alliance cannot assure the performance of such
alternate details.

4.0 RECEIVING & HANDLING ROOF MATERIALS
4.1 Material Inventory
Your material is carefully inspected and crated before
leaving the plant and accepted by the transportation
company as being complete and in satisfactory condition.
It is the carrier’s responsibility to deliver the shipment intact.
It is the consignee’s responsibility to inspect the shipment
for damages and shortages when it is delivered.
Conducting a material inventory at the time of delivery
is essential. By conducting the materials inventory,
the erector is able to identify any material shortage or
damage and avoid stopping installation later because of
such shortage or damage.
It is imperative that any shortages or damage of the
delivered materials be noted at once and clearly marked
on the bill of lading before signature of acceptance. Notify
Alliance immediately of any conicts. Alliance will not be
responsible for shortages or damages unless they are
noted on the bill of lading.
In the case of packaged components (such as clips,
fasteners and sealants, etc.), the quantities are marked on
their container and should be checked against the bill of
materials. Alliance must be notied of any shortages or
concealed damage within 15 days of delivery.
4.2 Equipment For Unloading and Lifting
Hoisting equipment is necessary to unload and position
the panels and accessory crates for site storage and
installation. The equipment must have sufcient capacity
and reach to place the material where it is required for
efcient installation.
Slings will be required to minimize panel damage. The
recommended slings are nylon straps of 6” minimum width
and of sufcient length to accommodate the panel bundle
girth.
A Spreader Bar will be required for the longer panel crates
to assure correct sling spacing and uniform lifting. The
Spreader Bar must be large enough to handle the maximum
panel bundle weight and length.
A Forklift is handy for unloading and placing shorter panel
and accessory crates.
4.3 Lifting Roof Panel Bundles
Under normal conditions, panel crates less than 35’ long
can be lifted with two slings spaced at third points. Panel
crates longer than 35’ can be lifted with three or more slings
located at quarter points using a Spreader Bar to achieve
correct sling spacing for uniform lift.
Slings should be located under the cross boards. Loads
should always be checked for secure hook-up, proper
balance, and lift clearance. Tag lines should be used if
necessary to control the load during lifting, especially if
operating in the wind.
Panel crates less than 25’ long may be lifted with a Forklift
only if the forks are spread at least 5’ apart and blocking
is used to prevent panel damage by the forks.

4.0 RECEIVING & HANDLING ROOF MATERIALS
4.4 Field Storage of Roof Materials
Upon acceptance of the shipment, the customer or his
representative is responsible for proper handling storage
and security of the roof materials. Alliance is not liable for
damage or loss of materials at the job site.
The Roof Panel bundles should be stored on the job site
in accordance with the following recommendations:
a. Store panels in a protected area, out of standing
water and drifting snow, etc.
b. Elevate panels with blocking to allow air circulation
under the bundle.
c. Slope panels for drainage of moisture from the
panels.
d. As necessary, cover panels with waterproof tarp,
allowing for air circulation (do not wrap tarp under
panel crate or restrict air movement).
e. Inspect panels daily for moisture accumulation.
f. If panel bundles contain moisture, the panels should
be dried and re-stacked. Use care in re-stacking
to avoid damage to panels.
g. Opened or re-stacked panel bundles should be
secured to prevent wind damage.
When moving panel bundles, extreme caution should be
taken to prevent damage to the panel edges. Uncrated
panels should be supported at each end and at 10’ spaces.
All bundles or loose panels on the roof should be banded
to the Roof Structurals at the end of each workday. On
steep roofs, provisions should be taken to prevent panels
and panel crates from sliding off the roof. Be sure to set
panel bundles on the roof in the proper direction for the
installation sequence.
Trim and accessories should be stored in a secure area
and protected from damage, weather, and theft. Fasteners,
sealants, closures, etc. should be stored out of the weather
and protected from contamination.

4.0 RECEIVING & HANDLING ROOF MATERIALS
4.5 Handling Individual Roof Panels
To lift individual panels, lift one side of the panel by the
seam letting it hang naturally to prevent buckling. Pick-up
points should not be more than 10’ apart. Do not pick-up
panels by the ends only, or in a at position.
If the individual panels are to be lifted to the roof by hand
line, the common method is to use the Vice Grip “C” clamps.
Position the clamps on the at of the panel as close as
possible to one edge so the panel is lifted in a vertical
position. The jaws of the Vice Grips must be padded to
prevent damage to the panel surface. The clamps should
be uniformly spaced, no more than 10’ apart and the hand
lines must be pulled in unison so that uneven lifting does
not buckle the panel. Be sure the clamps are tight on the
panel and the line is secure to prevent dropping the panel
which can result in personal injury and property damage.

5.1 Proper Tools
Before starting paneling, be sure that the proper equipment
and tools are on hand. The tools must be in good operating
condition and operators should adhere to safety precautions
at all times.
Improperly operating tools, too few tools, inadequate
power source, or other equipment deciencies slow down
the installation process. The cost of inefcient working is
usually greater than the cost of providing good equipment.
5.0 ROOF INSTALLATION BASICS

*These tools are specically designed for the AllianceLok
16 Roof Panel and are available from the Alliance.
5.3 Sealants
A. TEMPERATURE EFFECTS
Temperature extremes must be considered during
installation of the roof due to the sensitivity of sealants.
The recommended installation temperature range is 20º
F to 120º F. At colder temperatures, the sealant stiffens
resulting in loss of adhesion and compressibility. At hotter
temperatures, the sealant becomes too soft for practical
handling. On cold but sunny days, the panel’s surface may
become warm enough to accept the application of a heated
sealant even though the air temperature is below 20º F.
When overnight temperatures fall below freezing, the
sealant should be stored in a heated room so it will be warm
enough to use the following day. On hot days, the sealant
cartons should be stored off the roof in a cool and shaded
area. While on the roof, sealant rolls should be kept shaded
until actual use.
In very cold weather, it is recommended that the fasteners
be tightened slowly and only tight enough that the sealant
is in full contact with the panel or trim. Then on the next
sunny day, complete the tightening process after the sun
warms the panel and trim surfaces.
B. CONTAMINATION
To assure proper adhesion and sealing, the sealant
must have complete contact with adjoining surfaces.
Contaminants such as water, oil, dirt and dust prevent
such contact. The panel and trim surfaces must be dry
and thoroughly cleaned of all contaminants. Before
applying Tape Sealant, the sealant should be checked for
contaminants. If the sealant surfaces are contaminated, it
must not be used.
During cool weather, condensation or light mist can
accumulate on the panel and trim surface and not be easily
noticed. It is recommended that sealants always be kept
under protective cover and that the panel and trim surfaces
be wiped dry immediately before installation.
Tape Sealant is provided with a protective paper to
reduce contamination. Incomplete removal of the
protective paper will prevent the sealant’s adhesion to the
panel or trim surfaces. Always check that the protective
paper is completely removed. Do not remove the protective
paper until immediately before the panel or trim is installed
over the sealant.

5.0 ROOF INSTALLATION BASICS
5.3 Sealants (Continued)
C. COMPRESSION
To assure proper adhesion and seal, the Tape Sealant must
be compressed between the panel and trim surfaces with
rm and uniform pressure. In most cases, the required
pressure is applied by the clamping action of screws
pulling the adjoining surfaces together. However, the Tape
Sealant’s resistance to pressure becomes greater in cold
weather.
During cold weather, the fasteners must be tightened
slowly to allow the sealant time to compress. If the
fasteners are tightened too fast, the fastener may strip out
before the sealant compresses adequately, or the panel
or ash may deform in the immediate area of the fastener,
leaving the rest of the sealant insufciently compressed.
D. INSIDE CORNERS
An inside radius, such as where the panel at meets a
rib, is usually the most critical area to seal. A common
mistake for the installer, is to bridge the sealant across the
inside radius. When the lapping panel or trim is pushed
into place, the bridged sealant is stretched and thinned.
The sealant may then be too thin to adequately seal this
critical area.
When Tape Sealant is applied at an inside radius, it is
recommended that the sealant be folded back on itself,
then push the sealant fold into the radius.
5.4 Fasteners
A. SCREW GUN
Use torque control Screw Guns for driving self-drilling
screws. 2000-2500 RPM Screw Gun speeds are necessary
to attain efcient drilling speeds. High tool amperage (4 to
7 AMP) is required to achieve the proper torque for secure
fastening.
B. SOCKETS
Use good quality Sockets. Good tting Sockets reduce
wobble and stripping of the screw heads, especially the
alloy and capped heads. They also minimize objectionable
paint chipping and scufng on colored screws and minimize
damage to the protective coating on unpainted screws.
Magnetic Sockets collect drill shavings, which will build up
and eventually prevent the Socket from seating properly
on the screw heads. One method of removing the drill
shavings is to roll up a ball of Tape Sealant and push the
Socket into the sealant.
When the Socket is removed from the sealant, most of the
drill shavings will remain embedded in the sealant thereby
cleaning the Socket. This process should be repeated as
often as needed to keep the Socket clear of drill shavings.
C. SOCKET EXTENSION
A 4” or 6” Socket Extension is recommended for installing
the Panel Clip screws. With the extension, the screw can
be driven straight down without tilting the screw gun to
clear the panel or clip. Since Socket Extensions are slow
to wear out, it is usually more cost effective to purchase
Socket Extensions and good quality Sockets rather than
purchase Sockets with built-in extensions.
D. INSTALLATION
Before starting the screw, the materials to be joined must be
pressed together with foot or hand pressure. The pressure
must be maintained until the screw has drilled through all
the materials and the threads have engaged.

5.0 ROOF INSTALLATION BASICS
5.4 Fasteners (Continued)
Most self-drilling screws require 20 pounds of pressure to
maintain the drilling action and to start the thread cutting
action. Also, applying such pressure before starting the
Screw Gun will usually prevent tip walking or wandering.
If too little pressure is applied, the drill point may not cut
into the metal and the point will heat up and become dull.
If the pressure is too heavy, the bottom material may be
deected away, causing a standoff condition, or the drill tip
may be broken or split.
Screws must be held perpendicular to the panel or trim
surface during starting and driving.
For proper seating of the fastener-sealing washer, the panel
or trim surface must be clean and drill shavings must be
removed from under washers before seating. The fastener
must be driven perpendicular to the panel surface so that
the washer can seat level without warping or cupping.
Do not over drive screws. Over driving can strip the threads
and/or damage the sealing washer. Use Screw Gun with
torque control set to function properly for the combination
of fastener size, hole size and material thickness.
The fastener should be driven tight enough to uniformly
compress the washer but not so tight that the washer splits
or rolls out from under it’s metal dome. The recommended
procedure is to tighten the fastener until the sealing washer
just starts to visually bulge from under the metal dome.
As a good installation practice, all roof installers should
carry approved oversized screws. Upon stripping or
breaking a screw, the screw must be immediately removed
and replaced with the appropriate oversized screw. Do not
defer the screw replacement to be remembered and xed
later, or to be found by the clean-up crew. The majority of
such screws will be overlooked until the customer complains
of leakage.
5.5 Field Cutting Panels and Trim
A. ABRASIVE SAW PROBLEMS
Abrasive Saws (circular saws with friction disks) are not
recommended for cutting Roof Panels or trim. Abrasive
Saws create high heat that may burn away the protective
cladding from the panel edge, causing the edge to rust.
Also, Abrasive Saw dust contains ne, hot steel particles,
which accumulate on panel and trim surfaces where they
rust and can cause staining and rusting of those surfaces.
Rust caused by Abrasive Saw damage or abrasive dust
particles may be excluded from warranty claims.
B. SHEARING METHODS
It is recommended that panels and trim be cut with Shears
to provide a clean, undamaged cut. On shear cut edges,
the protective cladding extends to the edge of the cut and
is often wiped over the edge to further protect the base
metal.
Whenever possible, t the material so that the factory cut
edge is exposed and the eld cut edge is covered.
When eld cutting complex shapes, it is usually easier to
cut out a 1” wide strip using both left and right hand Shears.
The 1” cutout provides clearance to smoothly cut the ats
and the clearance to work the Shears around tight corners.
When making repetitive cuts (such as cutting panels at a
hip condition) it is recommended that a template be made
from a piece of drop-off panel or trim to provide fast and
accurate marking of the eld cut. When using panel material
for the template, cut off the top portion of the panel ribs so
that the template is easily laid onto the panel being marked.
C. MARKING PANELS
Avoid marking the panels for cutting, etc., in a manner that
will leave visible markings and stains, etc., on the nished
roof surface. Use chalk or felt tip ink markers. Do not use
graphite (lead) pencils on unpainted panel surfaces, the
graphite can cause rusting of the surface.
ROOF INSTALLATION BASICS

Caution: Failure to maintain panel coverage width within
the specied tolerance can cause faulty Roof Panel seams
which can result in seaming difculty or in severe cases
reduction in roof performance specications.
For proper t-up between the panel, sealant and closures or
endlap parts, the panels must be held to the width dimension
of the panel, as designated on the Erection Drawings, within
a 1/16” width tolerance per panel.
The accumulated coverage (start panel to nish panel)
tolerance is determined by the ability to keep the panels
parallel and to correctly t and assemble the nish rake
condition.
If the roof has conditions such as xed location penetrations,
parapets, re walls, etc., the accumulated panel coverage
may require tighter tolerances for proper t-up and weather
tightness of the roof system.
6.0 ROOF PANEL LAYOUT
6.1 Sheeting Direction and Modularity
Although the AllianceLok 16 Roof System is designed
so it can be installed in either direction (left to right or
right to left), there may be roof conditions which require a
specic sheeting direction. Check the Erection Drawings to
determine if a specic sheeting direction is required.
Panels with factory swagged ends must be installed with
the swag at the downslope end. Swagged panels can only
be installed in the left to right direction.
The recommended installation sequence is to complete
each panel run from eave to ridge before starting the next
panel run. This sequence will help ensure straight runs
and allow the insulation to be installed immediately ahead
of each panel run.
During installation of the roof, considerations must be
made for maintaining panel modularity. By maintaining
panel modularity, the Roof Panel sidelap and seam can
be properly assembled, the proper roof coverage can be
obtained and the standard perimeter parts will t properly
without necessity of eld modications or reordering of
parts, etc.
6.2 Layout & Checking for Coverage
Recommended for all roofs, but a must for large or
complex roofs, is to make a layout of the actual structure
(eld measured as described in section 3.3) so that the
Roof Panel start and stop dimensions can be laid out to
accommodate any structural misalignments.
When the optimal start and finish dimensions are
determined, a string line should be set to precisely locate
the leading edge of the start panel. After the start panel is
secured and engaged with the next panel, the start panel
seam will be the reference line for checking accumulated
panel coverage.
Panel coverage is always checked at the eave, ridge,
and end splices so that non-parallel seam (or dogleg)
conditions can be detected and corrected before they
become objectionable. The coverage check should be done
with a Measuring Tape held taut and measured to the same
side of the seam and always parallel to the eave to prevent
any measuring error.
Every four to six panel runs should be checked for panel
modularity. This will assure that the panels are maintaining
a straight line and proper coverage is being maintained.
If the panels are off module, they should be corrected by
equal adjustments of the next four to six panel runs.
6.3 Appearance Considerations
Although the above stated coverage tolerance will provide
for reasonable ease of installation and water tightness,
such visible conditions as non-parallel panel seams, dogleg
of the panel seam at the end splices, non-parallel nish
panel width, and mismatch of panel seams across the
ridge, may be objectionable and should be conrmed with
the customer before continuing roof installation.

7.0 INSPECTION OF ROOF ASSEMBLY DURING INSTALLATION
7.2 Inspection List (Continued)
Check that the panel and trim surfaces are not being
subjected to exposed metal objects and materials left on
the roof such as tools, material drop-off, fasteners, wire,
staples, drill and nibbler chips, saw and le particles, etc.
In the process of rusting, these materials will absorb the
panel’s protective coating thus leaving the panels exposed
to rusting.
Check that the panels and trim are not being subjected to
long term wet conditions such as standing water, consistent
sources of steam, mist, spray, dripping or runoff, wet debris,
wet insulation or other moisture holding material.
Check that the panels and trim are not subjected to direct
contact or runoff from corrosive materials such as copper
pipes and trim, uncured cement, treated lumber anti-icing
chemicals, strong solvents or other corrosive materials.
Check that Graphite Pencils were not used to mark on
unpainted surfaces. The graphite marks can cause rusting.
Check that the roof materials are not subjected to damaging
heat such as Cutting Torches, Abrasive Saws, etc.
M. UNSPECIFIED MATERIALS
Use of the wrong materials may cause installation and
performance problems and may void the performance and
material warranties.
Check that all installed roof system materials, especially
sealants and fasteners, are only those which are provided
or specied by Alliance for your specic project and are
used only as specied on the Erection Drawings and this
Installation Guide.
Alliance cannot be responsible for the performance of roof
materials that are not provided, specied or approved by
Alliance.
N. WARRANTY CONSIDERATIONS
If Alliance is to provide a weather tightness warranty for
your project Alliance requires that the Roof Curbs be pre-
approved by Alliance.All Roof Curbs should be compatible
with the Roof Panel. The Roof Curbs should have male and
female side ribs and water diverters at the upslope side of
the Roof Curb. Contact Alliance for approved Roof Curb
manufacturers.
INSPECTION OF ROOF ASSEMBLY
All Pipe Penetration Covers must have sealant (by others)
between the top of the Rubber Boot and Vent Pipe. Secure
boot to pipe with Stainless Steel Draw Band (by others).
