PREPARATION REQUIREMENTS & RECOMMENDATIONS
his detail & installation manual has been provided to serve as a basic guideline for installing the Mueller CF panel roof system.
T
This manual should be used in conjunction with the erection drawings to help ensure proper installation of this roof system.
In case of discrepancies, the erection drawings will govern over this installation guide.
It is the customer’s responsibility to ensure that a competent and experienced erection crew is chosen for the installation of
this roof system. It is also the customer’s responsibility to ensure the erection crew understands and follows this installation
manual and the erection drawings.
Mueller, Inc. is not responsible for any problems or defects caused by improper erection techniques. Any questions in
regards to clarifying the intent of this manual or the erection drawings should be directed to Mueller’s customer service
department at the address and phone number shown on the back cover.
Warning: CF Panels should not be installed on a roof that is less than a 3:12 pitch. When this panel is
installed on pitches less than 3:12, heavy rainfall may lead to water accumulation and possible leaks.
Note: It is important that the roof be properly prepared before installation begins.
Decking
Mueller, Inc. recommends our metal roofing systems be installed over CDX plywood wooden roof decking with a minimum
thickness of 15/32”. Note: If using treated lumber, special corrosive resistant screws are required. Ask your sales
representative for more information.
Stripping
The removal of existing roofing and the associated fasteners is generally necessary. This does not damage, and typically
improves, the structural capacity of wood decks. During removal, many shingle fasteners may remain embedded in the deck.
These fasteners can be pulled out or hammered flush with the deck.
Repairs
Deteriorated areas should be removed and replaced with material to closely match the existing thickness. The deck should
be sound and smooth, with fasteners flush with the surface, prior to the installation of the metal roof. New wood decking,
whether boards, planks, CDX plywood, or equal, should be the same thickness and have similar strength characteristics
and span ratings to that of the area being replaced. Deck fasteners that have backed out should have a new fastener installed
adjacent to it and the existing fastener should be removed. Loose or lifted boards, planks, plywood, and corners should
have additional fasteners installed to secure the existing deck in place.
Holes in wood decks that are 10" wide or less can be covered with 20-gauge steel. This steel plate should be galvanized
and must overlap the wood roof deck 4 inches minimum and be secured with fasteners 4 inches on center.
Fascia boards should be straight, level and in good condition. Any rotted or deteriorated boards should be replaced. All roof
framing and decking abnormalities will be transferred to the new metal roof if not corrected before sheeting begins.
Underlayment
New underlayment must be immediately installed over prepared roof decking. Mueller recommends Titanium or a minimum
30# felt. This underlayment should be installed with a minimum of a 2" side lap and a 6" end lap. Underlayment temporarily
protects the roof decking against water penetration. It should be installed using galvanized tin caps (not plastic caps). The
underlayment should be fastened to the deck with galvanized roofing nails with tin caps 12" on center in the field and 6" on
center at the sidelaps.
3
Flashing
Re-roofing projects incorporate metal flashing and metal counter-flashing. Some counter-flashing are embedded, such as
a masonry wall, or are installed behind existing siding. This metal, if not deteriorated, may be reused. The existing metal
can be cut, leaving approximately a minimum of 2" of flashing exposed, and new counter-flashing can be fastened to the
backside of the existing metal. Counter-flashing must be slightly higher than the top of the rib on the sheets to be installed.
SAFETY CONSIDERATIONS
s with all major construction projects, safety should be a primary concern. The erector or contractor should be sure
A
hat all OSHA safety rules are followed and that job safety is strictly adhered to.
t
The following safety equipment is highly recommended when installing metal roofing:
1. Safety rope and harness
2. Hand protection
3. Eye protection
4. Hearing protection
5. Soft rubber soled shoes
Metal roofing presents several specific safety issues:
1. Metal roofing is extremely slick and does not provide firm footing. Extreme care should be taken when:
A. Working on roofs with very steep pitches.
B. Working on roofs when moisture is present.
C. Working on roofs when high wind is a factor.
4
D. Working with long panels.
2. Metal edges are very sharp and should be handled with care.
3. Care should be used when lifting panels due to their weight.
4. Always check for overhead electrical lines and exercise care not to have metal sheets come in contact with them.
5. All electrical tools should be inspected regularly for damaged cases or frayed electric cords. Extension cords should
be inspected for damaged or frayed insulation. Tools which do not meet good safety standards should not be used.
CAUTION: Care should be taken when cutting sheets. Eye and hearing protection are important.
Panels may be slick!
Because of the demands of the manufacturing process, oil has been applied to the coil stock to protect the coil, as well as
the finished panel during manufacturing, shipping and storage. Metal panels must be wiped clean prior to panel installation.
NOTE: Always wear rubber soled work boots. When on the roof, use OSHA approved protection devices such as safety lines,
safety nets or catch platforms.
Unsecured Panels May Slip If Stepped On!
Never step on a single unsecured roof panel, or a stack of roof panels laying unattached on the roof. Secure each end of
the panel with clamps or appropriate fasteners and place walkboards of adequate size and strength in the flat of any
panels not fully secured to the roof and supported by panels on each side. Walkboards should run the full length of the
panel and be fastened together by drilling a hole near the end of each board and tied with rope to the next board. Cut a
groove in the bottom of each board so the board will lie flat and not tip back and forth because of the rope.
CARE AND HANDLING OF MUELLER SHEET METAL
elivery: Mueller takes every precaution to ensure that material is delivered to the customer damage-free and fully protected from
D
the elements during shipment. When the material is delivered to the customer it then becomes the customer’s responsibility to
protect the material from the elements, possible theft, and other damage. The following guidelines are recommended:
HANDLING: Proper care is required in unloading and handling panel bundles in order to prevent damage.
1. Bundles should remain banded (if possible) during the unloading process. Bundles should never be lifted by the
banding material.
2. Lift each bundle as close as possible to its center of gravity.
3. If the bundles are to be lifted with a crane, use a spreader bar of appropriate length and nylon band slings (do not
use wire rope slings as they will damage the material).
4. Depending on the panel length, some bundles may be lifted by a forklift. When using a forklift, the forks should be
spread to their maximum spacing, and the load centered on the forks. Sheets over 25' long require two forklifts.
5. After panel bundles are opened, individual sheets must be handled carefully to prevent panel buckling or damage to
the panel coating. When removing a sheet from a bundle it should be rolled off the bundle to prevent scratching of
the next sheet. Never drag or slide one sheet over another sheet. Sheets should not be picked up by the ends. Instead,
lift the sheet along its longitudinal edge and carry in a vertical position. For sheets over 10' long, two or more people
may be required to carry the sheet.
5
Wall and Roof Panels
Mueller’s wall and roof panels, including color coated, galvalume and galvanized, provide excellent service under widely
varied conditions. All unloading and erection personnel should fully understand that these panels are quality merchandise
which merit cautious care in handling.
Under no circumstances should panels be handled roughly. Packages of sheets should be lifted off the truck with extreme
care taken to ensure that no damage occurs to ends of the sheets or to side ribs. The packages should be stored off the
ground sufficiently high to allow air circulation underneath the packages. This avoids ground moisture and deters people
from walking on the packages. One end of the package should always be elevated to encourage drainage in case of rain.
All stacked metal panels are subject, to some degree, to localized discoloration or stain when water is trapped between their
closely nested surfaces. Mueller, Inc. exercises extreme caution during fabrication and shipping operations to ensure that
all panel stock is kept dry. However, due to climatic conditions, water formed by condensation of humid air can become
trapped between stacked sheets. Water can also be trapped between the stacked sheets when exposed to rain. This
discoloration caused by trapped moisture is often called “wet storage stain.”
The stain is usually superficial and has little effect on the appearance or service life of the panels as long as it is not
permitted to remain on the panels. However, moisture in contact with the surface of the panels over an extended
period can severely attack the finish and reduce the effective service life. Therefore, it is imperative that all panels be
inspected for moisture upon receipt of the order. If moisture is present, dry the panels at once and store in a dry,
warm place.
STORAGE
Storage: I
nd out of the elements if at all possible. If sheets are to
a
e stored outside, the following precautions should be
b
observed:
1. The storage area should be reasonably level, and
2. When stored on bare ground, place plastic ground
3. Store bundles at least 12 inches above ground level
4. Elevate one end of each bundle slightly to permit

prevent damage from rising water.
runoff of moisture from the top of the bundle or
from between sheets. A waterproof cover should be
placed loosely over the bundles to allow for air

or punctures in the waterproof cover.
Checking order at time of delivery:
heck each order carefully, as it is unloaded. Report any
C
bvious damage or shortages to the carrier immediately. If
o
damage or shortages are noted after delivery (at time of
unpacking) notify your Mueller representative immediate-
ly. Have invoice numbers and detailed descriptions of the
damage or shortage available. These procedures are for
your protection. A shortage or damage discovered later
can be caused by theft, misplacement, mishandling or
other causes and is not the responsibility of Mueller, Inc.
Underlayment: The underlayment should be one layer
of Titanium or 30# felt. The Titanium should have a 2"
side lap and a 6” end lap. The underlayment should be
fastened to the deck with galvanized roofing nails
with tin caps 12" on center in the field and 6" on
center at the sidelaps.
6. Re-cover opened bundles at the end of each work
day to prevent subsequent moisture damage.
Never Install Material if the Quality is in Question!
TOOLS REQUIRED
The following list of tools is recommended when installing metal roofing:
1. Aviation snips - left, right, straight 6. Square 11. Broom 16. Fire extinguisher
2. Screw gun 2500 RPM with appropriate nut drivers 7. Straight edge 12. Extension cords 17. Saw horses
3. Tape measure 8. Chalk line 13. Ladder 18. First aid kit

Oil Canning Reduction Trim on CF Panel
IMPORTANT INFORMATION
OIL CANNING
What is Oil Canning?
Oil canning is described as a wavy appearance often
occurring in the flat areas of formed metal products,
such as metal roofs. The structural integrity of the metal
is not affected by oil canning – it’s simply an aesthetic
issue. The term oil canning is an industry standard used
to describe this occurrence and is not a reason for
rejection.
Things to Expect
• If the deck is bowed up or has a belly, the new
sheets will oil can.
• High temperatures are often a factor when
waviness occurs. Once it gets cooler, the effect
will likely diminish.
• Changes in light – including overcast days, shade,
and intense sunlight – can affect the appearance
of oil canning. Oil canning will seem less
prominent in the shade but will be more
noticeable in brighter light.
0.50”
0.35”0.35”
0.85”
• The color of the metal panel can also affect the
appearance of oil canning. For example, oil
canning is more evident on galvalume, copper or
other metallic colors.
INSTALLATION
The purpose of this application is to reduce the effect of oil canning on the Mueller CF panels. It will not completely eliminate
oil canning on these panels. The strip must be applied down the flat section of the panel.
1. Prior to applying the panel, the oil canning reduction
trim should be positioned on the decking so that the
trim is centered in the flat section between the ribs of
the panel when it is applied.
2. The trim should be positioned to start 3’ from one end
and stop 3’ from the other end of each panel.
13
3. The trim should be held in place by screwing through
the trim into the decking at each end of the trim piece.
4. Reduction trim sections are 12’. These should be field
cut to length as needed. All joints should be butted not
lapped. Drops need to be utilized.

STANDARD ADJUSTABLE GABLE & STRIP INSTALLATION
. Starting at the corner, install the adjustable gable trim along the sloping gable,
1
placing it on top of the underlayment.
2. Attach with wafer head screws 5’ on centers (adjustable strip applied after valley trim).
3. Slide gable trim over eave trim at corner.
4. At the peak, one gable trim should be cut vertical to the ground
and overlap at the junction of the two gable trims.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
1. If valley trim is intersecting the gable, the valley must be installed first.
2. Pre-drill 1/8” holes on 12” centers along the length of adjustable gable strip #1476.
3. Butyl tape should be applied to the bottom of the strip covering pre-drilled holes. Place the strip
the desired distance from the outside edge of the gable trim (optimal distance 2”), making sure it
is aligned parallel to the gable, perpendicular to the eave line and between the open hem at the
edge of the adjustable gable trim and the outside of the trim.
4. The adjustable strip is attached to the roof with wafer head screws on 12” centers from eave to
ridge using pre-drilled holes, making sure the screws are applied through the butyl tape. This
condition exists in both Starting Panel and End Panel Installation.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.

HIGH SIDE RESIDENTIAL EAVE TRIM INSTALLATION
. Attach the high side trim (#0803) to the fascia with woodgrip screws on 5’ centers. Make sure the 6” side of the
1
trim is on the rooftop with the receiver hem resting on the highs.
2. Cap the ends of the trim by cutting and folding a tab that attaches to the gable trim. The hem must be removed
before a fold is made. Capping is usually easier to do before the trim is installed. If done after the trim is installed,
be sure and leave 6” of the trim overhanging to allow enough material for cut and folds.
3. Field cut enough metal closures (#0322) to complete the job.
4. Slide the 5/8” lip of the field cut metal closure into the receiver hem of the eave trim and position the closure on
the sheet.
5. Attach with one woodgrip screw, centered between each rib, through the hem of the ridge roll and metal closure,
into the decking. Care must be taken not to over-tighten the screws, as this will distort the trim and closures.
The screw hole can be pre-drilled, if desired.
6. All end laps should be at least 4”. Remove 4” of the hem on the overlapping piece and secure it to the overlapped
piece with caulk and stitch screws.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
NOTE: To comply with Texas
Windstorm Certification Testing,
#12x11 SDT Type A screws must
be used in place of the #9
Woodgrip screws.

VALLEY PANEL AND TRIM INSTALLATION
. Start at the low end, trim and place the valley flashing. The valley end should overhang the eave trim 1”.
1
2. If there is an end lap required in the valley pieces, caulk and lap at least 8”.
3. Use wafer head screws on 5’ centers to secure the valley in place along the outside edge.
4. Hem the edges of the valley over the eave trim, after trimming the center “V” back 1” to align with the
edge of the eave. Leave a tab to bend and cover the exposed opening of the center “V”.
5. Place butyl tape on the upper surface of the valley 6” up slope from the “V” of the valley trim,
before applying intersecting panels.
6. Field cut the panels that intersect the valley holding the end of the panel 4” back from the “V” of the
valley trim and parallel to the “V” of the valley.
7. Attach panel at valley using eave screw requirements for panel being installed.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.

STANDARD RIDGE ROLL and HIP INSTALLATION
. Lay a piece of the #0221 ridge roll or hip in position, making sure it is centered and in the correct position.
1
(Refer to step #8 for end capping instructions)
2. Temporarily fasten the ridge roll in place at one end with a woodgrip screw, positioning the screw through the hem
of the ridge roll, centered between the ribs.
3. Field cut enough metal closures (#0322) to complete the application.
4. Starting at the opposite end, slide the 5/8” lip of the (field cut) #0322 metal closure into both sides of the ridge
roll and position the metal closure on the sheet.
5. Attach with (1) woodgrip screw, centered between each rib, through the hem of the ridge roll and through the metal
closure, into the decking. Care must be taken not to over-tighten the screws, as this will distort the trim and closures.
The screw hole can be pre-drilled, if desired.
6. Continue installing the closures the entire length of the ridge or hip. Remove the temporary fastener, insert the closure,
and fasten through the existing hole as in step 4.
7. All end laps should be at least 4”. Remove 4” of the hem on each side of the overlapping piece and secure to the
overlapped piece with caulk and stitch screws.
8. Cap the end of all ridge rolls and hips by cutting and folding ends. The hem must be removed before the folds are made.
Capping is usually easier to do before the piece is installed. If done after installation, be sure and leave 6” of the ridge
roll or hip overhanging the peak or corner to allow enough material for cuts and folds.
9. Before the ridge trim is installed, if the pitch of the roof is 4:12 or less, the end of the panel that is under the
ridge or hip trim should be bent up between the high ribs to prevent moisture blow back.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.

the closure on the roof.
5. Attach using one woodgrip screw, centered between each rib, through the hem of the transition flashing and metal
closure, into the decking. Care must be taken not to over-tighten the screws as this will distort the trim and closure.
The screw hole can be pre-drilled, if desired.
6. All end laps should be at least 4”. Remove 4” of the hem on the overlapping piece and secure to the overlapped
piece with caulk and stitch screws.
7. Cap the ends of the trim by cutting and folding a tab that attaches to the gable trim. The hem must be removed
before a fold is made. Capping is usually easier to do before the trim is installed. If done after the trim is installed,
be sure and leave 6” of the trim overhanging to allow enough material for the cut and folds.
8. Before applying the upper panels, place a row of butyl tape continuously along the trim at a point where the
screws holding the lower end of the upper panel will go through the butyl tape. This is usually 4” uphill from the
bottom of the upper sheet. Use eave screw pattern.

CHIMNEY INSTALLATION
CHIMNEY FLASHING - UPHILL AND DOWNHILL
UPHILL
The uphill flashing will be 4” wider than the width of the
curb (2” on each side). Cut an 1/8” slot in the two uphill
corners of the panel slightly wider than 2 1/16”, so the
26
uphill flashing can slide through the two slots.
UPHILL
DOWNHILL
1. Trim both ends of the uphill and downhill sides of the
flashing as indicated.
2. Slide the uphill flashing into the slots of the roofing and
apply liberal amount of tube caulk.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
NOTE: To comply with Texas Windstorm Certification Testing, #12x11
SDT Type A screws must be used in place of the #9 Woodgrip screws.
Details are subject to change without prior notice.
CHIMNEY FLASHING - SIDE
1. Trim and bend the right side flashing as indicated.
2. Trim the left side in a similar fashion.
CHIMNEY INSTALLATION
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
NOTE: The left and right side flashing are mirror images of each other.
SIDE
FLASHING - VENT
Procedures:
1. Trim the opening in the flashing to 20% smaller than
the pipe diameter.
SIDE
SIDE
27
2. Slide the flashing down over the pipe.
3. Seal between the flashing and the roofing with
tube caulk and set the flashing.
4. Form the flashing to fit the profile of the roof.
5. Fasten the flashing with woodgrip screws 1” on centers.
NOTE: Alternate trim profiles are acceptable using the screw
pattern shown.
FOR PENETRATION THROUGH THE SIDELAP:
When a penetration occurs through or near the panel sidelap,
install tube caulk filling the female overlap to 12” above the
penetration and snap lock groove to 6” above to prevent
water from running downhill into the opening.
NOTE: In many cases it may be easier to locate
vent/pipe flashing in the flat area of the roof panel
(as shown) rather than have the penetration occur at a
panel rib. Determining panel layout prior to installation
often simplifies penetration flashing installation.
