IMAGINATION, FLEXIBILITY
AND SPACE
There’s nothing conventional about a Ritek® roof
A Ritek® roof has great potential for creating new design concepts. For
over 100 years, corrugated iron has provided shelter for Australian
homes. Today, through smart design, Ritek® has preserved the unique
Australian characteristic of corrugated iron and added insulation (EPS
core) to create a high strength roofing system that can achieve industry
leading spans of up to 11 metres, cantilevers of up to 4.2 metres and is
close to 50% faster to install than a conventional roof.
Available in straight, curved or multi-curved configurations, the roof is
flexible in structure and allows designers to manipulate the design
outcomes, by breaking the rules of conventional roof systems. The roof’s
contemporary Australian hallmark creates permeable boundaries
between the concepts of interior and exterior spaces while providing the
building’s occupants with high thermal comfort of up to R5.05.
When compared to a conventional roof system, a Ritek® roof can be
installed in one quick and easy operation, can reduce trades and
on-site labour components and can help eliminate the need for:
- Obtrusive, expensive roof structures
- Eave linings, plasterboard, internal painting, battens and insulation
MADE IN AUSTRALIA and ideally suited to Australia’s harsh, cyclone
prone environments, Ritek®’s insulated COLORBOND® roof systems
offer an entirely Australian finish to any building project.
Ritek® combines over 25 years of construction expertise with solid
business values, our roof systems can be customised to your needs and
are available in the full range of COLORBOND® colours, making it
easy to match to existing buildings. Our roof products are proven and
tested, supported by design tools and superior customer service to help
you turn your visual concept into reality.

RITEK® ROOFING - OUR BRANDS
Ritek® Custom Roof Panel
Design without boundaries. Imagine creating a sense of space in a building,
allowing uninterrupted views, keeping them free from columns and allowing
unimpeded internal space to evolve.
The flexibility of design of the Ritek® Custom Roof Panel starts with standard
Custom Orb COLORBOND® sheeting, bonded to both sides of profiled EPS.
The result is a high strength and distinctly unique Australian contemporary design
that seamlessly integrates the exterior with the interior.
The Custom Orb provides the finished ceiling so there’s no need for internal
ceiling plastering or painting, can be customised to your needs and is available
in curved, straight, multi-curved or bull-nose configurations.

Roof Panel.
has been
engineered without compromise to create a superior low pitch (2 degrees)
capability. You can maximise investment by reducing the height of a building and
add an extra floor, increasing saleable floor space.
The ecotekdroof panel consists of a Trimdeck profile upper sheet with a lower
sheet of COLORBOND® corrugated iron, bonded to a polystyrene core
available in a range of thicknesses.
Ritek® Lifesaver
Ritek’s New Corrosive Environment Roofing Solution with 15 Year Warranty.
No matter how close to the ocean you may build, Ritek’s anti corrosive roofing
solution is a lifesaver! The anti corrosive roof sheeting’s weather side has an
advanced tough polymer rich paint coating which is superior to the industry
benchmark PVF2 finish and is 8 times thicker than the standard in Australia.
The performance of Ritek’s anti corrosive roof sheeting is proven in use at 28 test
sites world-wide and has been the subject of CSIRO testing in Australia’s Port
Fairy, one of the most aggressive coastal environments in Australia.
Pay half the price of stainless! Historically to obtain any sort of warranty in a
severe marine environment stainless steel products are generally specified. With
Ritek’s new anti corrosive roofing solution, you can obtain a manufacturer’s
warranty for 15 years, no matter how close to the ocean you may be and you will
pay less than half the price of painted stainless steel.
Achieve your all-in-one roofing solution. Increase your roof warranty period to
25 years when used in a non-corrosive application. Conditions Apply.

“Use every weapon within
the rules and stretch the rules
to breaking point, I say.”
RESIDENTIAL / MULTI RESIDENTIAL
The desire to express identity through a home is
very powerful and sometimes rules need to be
broken.
Ritek’s award winning all-in-one insulated roof systems, provide high
yield strength to any building through our industry leading unsupported
spans of up to 11 metres and cantilevers that break all the rules, of up
to an unrivalled 4.2 metres - unsupported.
Our roof systems provide design flexibility and are available straight,
as curves or even multi-curves to provide unobstructed views that allow
internal space to evolve while greatly reducing the need for obtrusive
and costly supports such as beams, posts and trusses. Protection from
glare through our roof panel’s brilliant cantilever capability, allow
designers with unlimited applications to maximize openings for
windows for natural light.
Make the most of local climatic conditions, capture cool breezes and
improve interior space ventilation. Incorporating a Ritek® roof in your
next project will reduce the need for air-conditioning by helping
maintain temperatures for a higher level of thermal comfort, therefore
reducing associated high energy costs and the building’s carbon
footprint.
The light weight architectural roof panels are long life and low in
maintenance. They can be installed quickly and easily at a fraction of
the time of conventional roofing construction methods, ensuring that a
homeowner can move in sooner.
A Ritek® roof system removes the boundaries and limitations that
constrain conventional roof design. In order to create a uniquely
Australian home design as individual as you are, you need to
break the rules.
“Imagination
has rules, but
we can only guess
what they are.”
PROJECT: WATTLE STREET BUILDING DESIGN: KIDD + CO www.kiddco.com.au
COMMERCIAL
Good commercial building design enables us to live and work more efficiently,
comfortably, profitably, securely and enjoyably in a more aesthetic and productive
environment.
A Ritek® roof provides high level thermal comfort for a building’s occupants and reduces the need for air-conditioning or
heating requirements and therefore the size of a building’s carbon foot print. Improved thermal performance supports staff
comfort and can potentially increase productivity in commercial premises.
Our roofing systems are not only functional, they provide designers with flexibility through our high yield strength roof systems
and can be fully customised to meet your commercial needs. A Ritek® roof is cyclone tested, has a Group 1 fire rating, is fully
warranted for up to 25 years and BCA Part J compliant.
For a commercial building that is not limited by conventional roof building constraints, make your commercial buildng a
signature of your business image with a Ritek® roof.

INFRASTRUCTURE, COMMUNITY
AND EDUCATION
Modern public buildings such as education and community spaces often
reflect both the physical and social needs of a community, utilise
innovation and evoke visual emotion. They help us define our identity
and are often a work of art within a landscape with most innovative
architecture currently being large Australian infrastructure projects.
Conventional roofing methods limit designers who want to create a
contemporary community space. A Ritek® roof can provide wide open
spaces, by removing some of the unsightly and costly obstructions such
as supports, is low in maintenance and provides high thermal comfort
to the building’s occupants, reducing the size of a building’s carbon
footprint. For a truly unique public space the Ritek® roof can be
customised to your needs and is available in straight, curved or
multi-curved
configurations,
providing
a
uniquely
Australian
contemporary aesthetic that seamlessly merges the interior of the
building to the exterior.
BETTER BUILDINGS
= BRIGHTER FUTURE
The time to build better classrooms for future generations is NOW!
Most students spend their days in schools that are often unhealthy,
restricting their ability to learn. Sustainable school building design
provides an astonishingly cost-effective way to enhance student
learning, reduce health issues and operational costs while increasing
school quality and competitiveness.
By incorporating sustainable materials such as a Ritek® roof for the
broader community’s 21st century building needs, you can achieve
rapid construction of your project, significant financial savings and
contribute positively to the environmental impact of a building now and
into the future.
“The Ritek® Custom Roof Panel’s sleek lines are attractive and the installation process
was smooth as the panels are prefabricated. We were afforded significant savings due
to the speed and ease of installation.”
“The brilliant cantilever and spanning features of the roof panels are a designer’s dream
as they provide the ability to use both curved and straight configurations. We are very
happy with the overall result the roof provides, which is a contemporary finish that
complements the eco-efficiency and overall aesthetics of the building.”
Award winning designer John Whittingham, Director - Allen Jack+Cottier, Sydney

ENVIRONMENTAL SUSTAINABILITY
Ritek® Building Solutions was initially borne from the need to preserve our precious natural resources. Long before
sustainability had become 'popular', our mission statement was to encourage sustainability and efficiency in the building
industry. Ritek® has dedicated over 25 years to changing market perceptions and has made significant contributions to
encouraging sustainable building practices.
Energy Conservation
Increase the efficiency of a building and utilise Ritek’s unvrivalled cantilever capability. Provide protection from glare allowing
increased window openings, enhancing natural light. Ritek® insulated roof panels can further reduce energy needs and
impact on emissions, are fibre free and help maintain temperatures for a higher level of thermal comfort. Further savings in
project and energy costs are achieved by the elimination of material and trade labour costs for paint and eave linings.
Materials Efficiency & Waste Reduction
Ritek’s roof panels are prefabricated so they are quick and easy to install, reduce construction waste going back into landfill
and allow for a safer and cleaner worksite. Ritek® roof system’s superior spanning and cantilever capability reduces the need
for expensive and obtrusive support structures such as roof trusses and beams. Our roof panel can be disassembled and used
in another building making it 100% recyclable in its entire form.
Indoor Environmental Quality
Make the most of local climatic conditions, capture cool breezes and improve interior space ventilation with a Ritek® roof. The
prefinished ceiling lining of COLORBOND® sheeting means the insulation is completely contained, clean and non-allergenic
as there are no volatile organic compounds (VOC) or Formaldehyde content on the finished product.
Durability
Our roof systems high yield strength and durability are low maintenance aside from the occasional wash down of soffits (can
also be easily repaired with paint). Each roof panel is COLORBOND® coated and proven in use, cyclone tested and achieves
a Group 1 fire rating. Ritek® Roof Systems have been certified with Group 1 fire rating in accordance with the BCA2006
Specification C1.10a, which is the highest rating under the Building Council of Australia. It has a Smoke Growth Rate Index
(SMOGRRC) <100. The Ritek® Lifesaver panel is suitable for use in harsh marine and corrosive environments.
Sustainable Projects
The Ecovillage at Currumbin, was awarded the world’s finest example of sustainable urban development and best residential
subdivision. It also won the HIA Greensmart Building of the year award using Ritek’s Custom Roof Panel in their “Living
Laboratory”. The roof was concave and was used to harvest rainwater and to provide thermal comfort to the building’s
occupants.
About EPS
From a global warming perspective, it has been estimated that the effective application of EPS can reduce carbon dioxide
emissions by up to 50% when used in insulation application (PACIA, n.d.). Furthermore, the insulation performance of EPS
does not deteriorate during its lifetime therefore the reduction in emissions lasts the full lifetime of a building. From a landfill
perspective, EPS remains inert, non-biodegradable and non-toxic.
NB: On an average, for every kg of oil used in panel manufacture, about 200kg will be saved in reduced heating demand over the lifespan of the panel.
