INTRODUCTION
INTRODUCTION
 Metal roofing has been around for centuries. However, the process to make the
finished roof panel has evolved greatly. Metal roof panels were originally made by
hand and the panels were bent into the proper configuration. When metal brakes
became available, they were used to bend the panels but the length of the panel
was limited to the length of the brake.
 Fixed in place Rollformers solved this problem by producing a machine that
manufactured the panel for you and provided panels at any length that could be
shipped to a project. With today’s advances, Portable Rollforming equipment is
available and able to produce multiple panel profiles at any length anywhere.
 Before we get into the benefits of Portable Rollforming, let’s first discuss how the
process works.
WHAT IS
ROLLFORMING?
WHAT IS ROLLFORMING?
Rollforming feeds a continuous sheet of material (i.e. steel, aluminum, copper) via
an expandable die-coiler through a series of rollers and Rollforming dies that bend
the material slightly at each pass to form a particular metal roof panel profile.

 Portable Rollforming is used to produce Standing Seam Metal Roof Systems
(SSMRS) in mechanically seamed, various snaplock and face-fastened panels.
 Can produce panels in steel, aluminum, stainless steel, copper and zinc.
 Produces 60 to 80 feet of formed panel per minute.
 Can have the capability to switch out forming dies to form a different type of
SSMRS.
 Can have the ability to run off a gas or electric motor.
 Can be controlled manually or used with a batch computer.

HOW PORTABLE
ROLLFORMING
This is an example of what the forming
dies in a Portable Rollformer could look
like. As the flat, metal coil enters the
machine, it passes through a series of
forming dies. These dies slowly form
the panel through each stage. Once the
metal has finished going through the
forming dies, a rigid, finished panel exits
the machine ready to be cut to the
desired length. The type of forming dies
that are installed in the Portable
Rollformer determine which roof panel
profile is made. Many Portable
rollformers have the ability to switch the
forming dies to produce a variety of roof
panel profiles.

It’s GREEN
 Besides metals’ already eco-friendly properties, Portable Rollforming allows you
to ship metal coil rather than shipping formed panels. This reduces cost and
protects the product from being damaged during transit. This also limits the
amount of trucks necessary to ship the material reducing emissions.

More control of your project
 Portable Rollforming allows the contractor to take control of the product. If a
panel is damaged on the project, it can be replaced on site with no wait. It also
allows the contractor to adjust panel length and quantity on the fly if there are
discrepancies on the project.

Getting the panels on the roof
 All panels have to get on the roof somehow. With a Portable Rollformer, instead
of craning panels a little at a time to the roof, the Rollformer itself can be lifted
and angled to shoot the panels from the machine directly onto the roof. This is
especially helpful when dealing with large projects and long panels.

UL CONSTRUCTION
As we just covered, most Portable Rollformers come with their own UL construction
numbers. So let’s talk about how a UL 90 rating is achieved.
WHAT IS
UL 90? WHAT IS UL 90?
 UL 90 is the highest of the three ratings that can be achieved during a UL 580
uplift test. It does not correlate to a wind speed but rather the test relates to
uplift pressures and loads measured in pounds per square foot.
 The test pressure for a UL 90 rating is a 105 psf. This number does not include a
safety factor which is 50% of the test pressure. In this case, the design pressure
with safety factor would be –52.5 psf.

 UL 90 is part of the UL 580 uplift test.
 UL 580 is a test procedure for the uplift resistance of roof assemblies. To better
understand how this rating is achieved, you must first understand how the UL
580 test is performed.
HOW TO HOW

To perform a UL 580 test a 10’ x 10’ test specimen is made consisting of the deck
assembly and panel profile. The specimen is then placed into a test chamber where
positive and negative pressure is applied to the test specimen to determine uplift
resistance.

 Once the test starts the specimen is
tested in three classes: Class 30, Class
60 and Class 90.
 Each class has five phases and lasts 80
minutes.
 You must pass each phase of the test in
order to move forward to the next class.
In other words, the test specimen must
pass class 30, then pass class 60, then
class 90. You cannot get a UL 90 rating
without first testing to class 30 and class
60.

UL CONSTRUCTION
 Now that we have covered how to get the UL 90 rating, we will go over a UL
Construction Number and what to look for when reading it.
 Reading a UL Construction Number is pretty basic, but there are two key factors
that need to be considered when specifying the Construction Number. Both of
these are under the deck assembly section.
UL CONSTRUCTION
NUMBERS NUMBERS
UL CONSTRUCTION
First thing to look at is how the deck is attached?
 The deck needs to be attached per the UL Construction Number in order for the
engineering to be valid.
OR
UL CONSTRUCTION
NUMBERS NUMBERS
UL CONSTRUCTION
For example:
 Most plywood decking is usually nailed to the supports using ring shank nails,
however, if the UL Construction Number calls for the decking to be screwed down,
then that’s how it will need to be installed for the engineering to be valid.
UL CONSTRUCTION
NUMBERS NUMBERS
UL CONSTRUCTION
The second thing to look at is if the decking is sealed
 For example a UL Construction Number could read: “All joints to be sealed with
one part urethane sealant feathered out from the joint.”
UL CONSTRUCTION
NUMBERS NUMBERS
UL CONSTRUCTION
For example:
 The plywood decking on a project
would have to have all the seams
caulked where the plywood butts up
to one another so no air could pass
through for the engineering to be
valid. During the UL 580 test, the
sealed joints stop the positive
pressure from coming through the
decking to get to the roof panels.

First – Increased project costs and time
 Labor is always more expensive than materials. Depending on how much extra
labor will be needed to install the substrate appropriately, project costs could go
up.
 Extra labor requires extra time which should be taken into consideration for
scheduling.

Second – Void of engineering
 Specified or not, if a roof failure should take place and the decking is not
installed per the UL Construction Number specified, then it is automatically a bad

In a perfect world, this would not be a concern, but because the deck attachment is
commonly overlooked, it is important to cover this. If anything should happen, the
person who will feel the full effect of the situation is the building owner.

UL 580 -Test for Uplift Resistance of Roof Assemblies over a solid substrate:
Scope
 1.1 The method of test specified in this standard is intended to determine the uplift
resistance of roof assemblies consisting of the roof deck and roof covering materials.
It is applicable to any type of roof assembly which is adaptable to the test equipment.
Tests to evaluate other potential hazards of roof assemblies are not within the scope
of these requirements.
 1.2 The purpose of this test is to evaluate the comparative resistance of roof
assemblies to positive and negative pressures.
 1.3 The test evaluates the roof deck, its attachment to supports, and roof covering
materials. It does not evaluate roofs adjacent to chimneys, overhanging eaves, or
similar construction, connections of the assembly to main structural supports (girders,
columns, or other supports), structural integrity of secondary supports (purlins, joists,
bulb tees, or the like), or deterioration of roofing materials.

UL 1897 - Uplift Tests for Roof Covering Systems
Scope
 1.1 The test method specified in this Standard is intended to provide uplift
resistance data for the evaluation of the attachment of roof covering systems to
roof decks by using differential air pressures. It is applicable to any type of
roofing system which is adaptable to the test equipment.
 1.2 The test evaluates the roof covering systems method of attachment,
including all components such as base sheets, ply sheets, slip sheets,
membranes, etc. and insulation, if used. Supporting roof decks are evaluated
only with respect to span conditions and physical properties such as gauge, yield
strength, grade, size and/or species of lumber and related factors which affect
fastener attachment or bond strength.
APPLICABLE
TESTING
APPLICABLE
TESTING
Scope
 1.3 This test method provides a comparative measure of the uplift resistance for
roofing systems by means of static differential pressure. The method does not
necessarily simulate the actual dynamic uplift pressures encountered by roofing
systems. Uplift pressures on a roofing system are dependent upon many factors
such as wind gusts, building shape, edge configuration, and the terrain
surrounding the building. A method to calculate the uplift pressures on roof
assemblies is contained in the Standard for Minimum Design Loads for Buildings
and Other Structures, American Society of Civil Engineers, ANSI/ASCE 7.
 1.4 The purpose of this test method is to provide data regarding the securement
of the roofing system to the roof deck based upon a short-term static load. For
information regarding uplift resistance of complete roof deck assemblies
including the roof deck and its attachment to supports refer to the subject
category Roof Deck Construction (TGKX) in UL's Buildings Materials Directory.

UL 1897
 UL 1897 is an uplift test for a SSMR installed over solid substrate. It is the
continuation of the UL 580 test after the test specimen has reached UL 90. After
successful completion of UL 90, the pressure is increased in the test chamber by
set increments until the test specimen experiences ultimate failure, i.e. panels
disengaging, clip disengaging or permanent kinks in the vertical seam of the roof
panel.

panels and anchor-to-panel attachments for roof or siding systems under uniform static air
pressure differences using a test chamber or support surface.
 1.2 The provisions of this test method are applicable to standing seam, trapezoidal, ribbed,
or corrugated metal panels in the range of thickness from 0.012 to 0.050-in. (0.3 to 1.3mm) and apply to the evaluation of uniform pressure applied to single-skin construction or
one sheet metal layer of multiple-skin construction. They do not cover requirements for the
construction of a specimen to determine the load sharing that can occur with either
composite or multiple-layer construction such as: (1) metal cladding over wood sheathing; or
(2) field assemblies of insulation sandwiched between corrugated or formed metal panels.

INSTALLATION DETAILS
Both details shown are appropriate for use on a gable installation and both would be
approved for use on a project requiring a weathertight warranty; however, Gable
Detail 1 has five extra accessories that would need to be purchased and then
installed to complete the assembly. Gable Detail 2 has less pieces to buy and install
which would bring down project costs.
INSTALLATION DETAILS
INSTALLATION DETAILS
Another way to break it down is to look at it like this:
 For Gable Detail 1, you are using 4 feet of product per linear foot plus 5 fasteners
per linear foot with 2 pop rivets every 3 linear feet.
 For Gable Detail 2, you are using 1 foot of product and 2 fasteners per linear foot.
