PREPARATION REQUIREMENTS & RECOMMENDATIONS
his detail & installation manual has been provided to serve as a basic guideline for installing the Mueller R & U-Panel
T
oof system. This manual should be used in conjunction with the erection drawings to help ensure proper installation
r
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 sales department at
the address and phone number shown on the back cover.
Warning! When these panels are installed on roofs with less than recommended pitches (R-Panel recommended
minimum pitch is 1/2:12, U-Panel recommended minimum pitch is 1:12), heavy rainfall may lead to water accumulation and possible leaks.
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” or equal. 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 optional with R & U-Panels. 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 sidelap.
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
A
primary concern. The erector or contractor should be sure that
all OSHA safety rules are followed and that job safety is strictly
adhered to.
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
earing protection are important.
h
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.
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 sidelap.
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
4. Caulking gun 9. Vise grips 14. Hammer 19. Tarp
5. Safety equipment: goggles, hard hat, 10. Gloves 15. Drill bits 20. Electric shear or nibbler
and soft rubber soled shoes
CAUTION: Whenever using any type of power equipment, it is important to follow the manufacturer’s recommendation
for use. Always be aware of the danger involved when using electric or air powered equipment.
Never Install Material if the Quality is in Question!
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.
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.”
5
WARNING! Mueller trim comes with a protective film
coating to aid in the prevention of scuffing. Do not
allow this film to be exposed to the sun. Exposure will
bond the film to the metal making removal difficult.
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: It is recommended that sheets be kept covered and
out of the elements if at all possible. If sheets are to be stored
outside, the following precautions should be observed:
1. The storage area should be reasonably level, and located so
as to minimize handling.
2. When stored on bare ground, place plastic ground cover
under the bundles to minimize condensation on the sheets
from ground moisture.
3. Store bundles at least 12 inches above ground level to allow
air circulation beneath the bundle, and to prevent damage
from rising water.
4. Elevate one end of each bundle slightly to permit 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 circulation under the cover.
5. Inspect stored bundles daily and repair any tears or
punctures in the waterproof cover.
6. Re-cover opened bundles at the end of each work day to
prevent subsequent moisture damage.

Checking order at time of delivery:
Check each order carefully, as it is unloaded. Report any
obvious damage or shortages to the carrier immediately. If
damage or shortages are noted after delivery (at time of
unpacking) notify your Mueller representative immediately.
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.
Note: Always remove metal filings from surface of
panels at the end of each work period. Rusting filings
can destroy the paint finish and void warranty.
