Any kind of business need a perfect roof for their business, Royal Roofing Ltd Calgary provides all kind of roofs and metal sheets for commercial roofs.

1. COMMERCIAL AND INDUSTRIAL ROOFS
LOW-SLOPE ROOFS
Commercial and industrial roof systems are generally low slope (flat) systems that require extreme care and skill
during installation in order to be trouble-free. “Low-sloped roofs are defined as those roofs with a slope less
than or equal to 3:12 (25 percent). However, with the exception of metal roofs, most low-slope roofs have a
slope of about ¼:12 (2 percent). Steep-slope roofs are defined as those roofs with a slope greater than 3:12 (25
percent)”. (www.wbdg.org).
SINGLE-PLY REVOLUTION
“The introduction and rapid acceptance of single-ply membranes into the U.S. roofing market in the 1970s was
likely the most significant roofing industry change in twentieth century. Another notable development in the
1970s was the widespread acceptance of rigid foam roof insulations, although this pales in comparison with the
development of single-ply membranes. It is doubtful that another issue will be as revolutionary as the
introduction of the single-plies. Since the single-ply revolution, changes in the roofing industry have been
primarily driven by environmental and worker health issues and the pursuit of methods to reduce the amount of
labor needed to install roof systems.” (www.wbdg.org)

2. COMPONENTS OF A MEMBRANE ROOF SYSTEM
Royal Roofing Ltd. specializes in commercial and industrial roofs and in the application of single-ply
EPDM and TPO membranes manufactured by Firestone Building Products of Canada with 25 to 30 year
warranties. The information shown below is from www.firestonebpco.ca.
RubberGard EPDM Roofing Systems
Since its introduction in 1980, Firestone RubberGard EPDM has dominated
the single-ply roofing market through its proven performance, durability and
flexibility over a wide range of building types. RubberGard has delivered
more than two decades of commercial roofing success by building upon a
heritage of innovation in rubber polymer technology for the rubber
compounding and tire industries. Based on ethylene propylene diene
monomer, the versatile membrane offers a variety of installation options
including fully adhered, ballasted or mechanically attached, that deliver
superior long-term weatherability and exhibit exceptional wind uplift
resistance.

3. Platinum EPDM Roofing Systems
Firestone RubberGard Platinum delivers the commercial roofing industry’s
first 30-year warranty covering incidental punctures, high winds and hail
up to two inches in diameter. Platinum combines the strength of 90-mil
RubberGard EPDM with Firestone HailGard composite insulation for
outstanding thermal performance and puncture resistance. Seamed with
Firestone QuickSeam Tape, Platinum offers watertight seams with
increased strength.
UltraPly TPO Roofing Systems
Firestone UltraPly TPO is a flexible, hot-air welded thermoplastic
polyolefin roofing membrane available in both 8’ and 10’ widths. Suitable
for a variety of low slope applications, UltraPly TPO features a white, tan
or gray reflective surface that can help reduce a building’s cooling
requirements.
Platinum TPO Roofing Systems
Firestone UltraPly Platinum TPO is the industry’s first thermoplastic
roofing system backed by a 30-year warranty. Comprised of a durable,
80-mil-thick scrim-reinforced membrane, UltraPly Platinum can be either
fully adhered or mechanically attached to Firestone HailGard insulation
and fastened to a wide range of deck substrates. The reflective surface
of UltraPly Platinum meets EnergyStar standards for energy savings in
warm climates, making it an exceptional long-term roofing value for
building owners.

4. UltraPly TPO InvisiWeld System
The UltraPly TPO InvisiWeld system from Firestone is a non-
penetrating mechanical fastening solution that greatly reduces
labour while increasing the wind uplift resistance of the Firestone
UltraPly TPO membrane. This VOC-free system features TPO-
coated Firestone UltraPly TPO InvisiWeld Plates attached to the
UltraPly TPO membrane using an induction welding tool. The
InvisiWeld System meets or exceeds Factory Mutual (FM) approvals
and requirements. The roofing season can be extended since the
InvisiWeld System functions well in many climates, including
extremely cold environments where adhesives and asphalt are
difficult to use. Eliminating insulation seam plates and fasteners
reduces installation time and labor costs. Membrane waste is less
because a 6″ in-seam lap is no longer needed. This system requires
less material for perimeters and corners than other attachment
methods.
Metal Roofs: Warranted UNA-CLAD UC Panels
Available in copper, zinc, and 31 standard PVDF-painted aluminum
and steel colors, Firestone UC Roofing System Panels can be used
with all Firestone Roofing Systems and Firestone ISO 95+ polyiso
insulation. Firestone offers a wide selection of accessories for all metal
roofing systems. Select UC Roofing System Panels are also backed
by Firestone’s Red Shield Warranty coverage when used in an
architectural application. The UNA-CLAD™ UC-3, UC-4, UC-6 and
UC-14 metal roofing systems are also eligible for the 30-Year Platinum
Warranty.
Firestone UNA-CLAD UC-3 Roofing Panel is a factory formed double-lock, architectural standing seam metal
roof panel that provides a traditional look and utilizes mechanical seaming to enhance design needs. With its
proven high wind performance capabilities, UC-3 Roofing Panel can be curved and tapered and accommodate
complex architectural geometry. It may qualify for our 30-Year Platinum Warranty.
Firestone UNA-CLAD UC-4 Roofing Panel is a patented self-locking, architectural standing seam metal roof
panel that completely eliminates the need for clips. UC-4 Roofing Panel’s unique integral fastening flange
accommodates thermal movement, and its easy snap-together seam saves installation time and money.
Firestone’s 25-year Millennium Warranty may be available for this system as well.
Firestone UNA-CLAD UC-6 Double-Lock Standing Seam Roofing Panel utilizes the proven seaming
process of Pittsburgh Locking in conjunction with the floating action of a concealed clip assembly. This design
allows for expansion and contraction caused by natural elements to provide a virtually leak proof roof with
exceptional uplift ratings. UC-6 Roofing Panels have the ability to span open purlins. This system may qualify
for a 30-year Platinum Warranty.
The Firestone UNA-CLAD UC-14 Roofing Panel is a factory formed architectural standing seam metal roof
panel with a proven 1 3/4″ tall continuous interlocking seam that snaps together for ease of installation. The
system uses a concealed clip fastening system for added protection and is able to accommodate very long
panels and virtually unlimited thermal expansion.

5. ADVANTAGES OF METAL ROOFS
The Ducker Research Company study showed that the life cycle cost of a metal roof is significantly less than
BUR and Single Ply roofing. Steel roofing had the lowest maintenance costs and had, on average, a 17+ year
greater lifespan than the other two roofing systems. The study also concluded that building owners believe that
service life and life cycle costs are the most important factors in roofing material selection and overall, metal
roofing is by far the best option based on its lowest life cycle cost. Add to this the fact that steel roofing is 100%
recyclable, has industry leading recycled content and easily qualifies for LEED Canada certification.” Canadian
Sheet Steel Building Institute (www.cssbi.ca).
Insulation
Firestone ISO 95+ Polyiso Insulation offers high-energy efficiency
through the highest R-value ratings per inch versus other insulation
materials and is compatible with all types of commercial roofing
systems. The lightweight, easy-to-handle insulation is especially
suited for direct application on FM approved and UL classified steel
roof deck assemblies. Standard flat ISO 95+ is available in board
sizes of 4’ x 4’ and 4’ x 8’ and in thicknesses from 1” to 4″.
Firestone ISO 300 offers a closed-cell polyiso foam core laminated
to a polymer coated glass-fiber mat facer that is moisture resistant.
ISO 300 was originally designed for cold-applied modified bitumen
roofing systems, because it maximizes coverage rates of adhesives
and achieves enhanced code approvals for some assemblies. ISO
300 can be used with all Firestone Roofing Systems.

6. CERTIFIED ROOFERS
Our roofers have been certified by Firestone Building Products to install a variety of Firestone roofing systems.
As indicated by Firestone “Contractor Quality Training Seminars are designed for key field employees,
such as superintendents, crew leaders and skilled installers, who are directly responsible for
achieving quality roof installations. The seminars combine classroom activities with hands-on
training and cover the installation of RubberGard EPDM, UltraPly TPO, UNA-CLAD Metal and 2-
Ply SBS Modified Bitumen roofing systems.Participation is open to Firestone-licensed contractors
and contractors interested in becoming Firestone-licensed”.
RISK ELIMINATION
Royal Roofing does not use PVC roofing membranes because of their poor performance in North America, nor
SBS Modified Bitumen membranes because they requires a torch on application, thus increasing the risk of
fires. According to the Infrastructure Health and Safety Association (IHSA): Torch-applied operations can be
hazardous to roofers and the public. Torching can reach temperatures over 1093°C or 2000°F.
Roofers may suffer serious burns from the torch or the hot modified bitumen they are applying. In
addition, temperatures generated by torching applications have been known to start fires that may
smoulder out of sight, only to burst into flame later, well after torching is over.
EXPERTISE IN CONDOMINIUM AND RESIDENTIAL ROOFING
At the same time we work with many property management companies to re-roof or repair condominiums, and
we are experts in both low-slope and steep slope roofs. See Condominum and Residential Roofs
