What is the difference between concrete and
Concrete tiles are one of
Australia's most popular roofing materials. They offer
value for money and a wide choice of colours. Terracotta
tiles have been used for thousands of years and offer
natural durability in both colour and quality. Made to
Australian Standards, terracotta and concrete tiles are
manufactured to withstand harsh climatic conditions and
marine environments. All roof tiles manufactured to
AS2049 are salt-safe and frost resistant, making them
suitable for any location, including coastal areas. Are
roof tiles more durable than other roofing options?
Tiles outlast most other roofing options. Roof tile
manufacturers generally offer warranties of 50 years,
while some metal roofing products are only covered by
warranty for 30 years.
What is the best roofing material to endure
Terracotta and concrete roof tiles
offer more resistance to wind suction than lighter
weight materials such as metal sheeting. When damage is
sustained during a storm, you only need to replace the
individual damaged tiles. When a metal roof is damaged,
entire sheets need to be replaced, which makes for a
more costly repair bill.
Which roofing material is better at blocking
The density of tiles helps
reduce external sound, such as aircraft and road noise
and particularly rain and hail. A tiled roof has a sound
reduction potential of 30 decibels compared to only 12
decibels for steel sheeting. Also, tiled roofs won't
creak and groan in reaction to changing
I live near the coast. What is the best
roofing solution for coastal conditions?
Concrete or terracotta roof tiles are ideal
for coastal regions as most products are suitable for
marine environments and their high salt content. In the
absence of rain, metal roofing requires frequent hosing
down in high salt concentration areas, which can pose
difficulties with water restrictions.
Different styles and
colours can create a mood or make a statement, help you
stand out in the crowd or blend in with the streetscape.
It's an entirely individual choice. In many cases, the
design determines your roofing material selection. With
our wide range of traditional and contemporary tiles and
extensive choice of colours, you can combine different
finishes and shades to create a roof that is as subtle
or dramatic as your design. Because choosing the right
tile can be a time consuming process, expert product
consultants are on hand at our display centres to assist
in finding the style and colour that will best create
that individual look. Once tiles are installed there is
little or no maintenance. Should a section of the roof
ever be damaged, there is the added advantage of
individual tile replacement over large steel sheets. The
use of a flexible pointing material to fix ridge capping
enhances security in high winds.

Standards. Terracotta has been used for thousands of
years both for its incredible durability and its beauty.

This absorption does not affect the tile's

I have a problem with my roof tiles. Who
should I contact?
In the first instance you
should contact the installer/supplier of the roof tiles
to report the issue. For ongoing matters of complaint,
contact the relevant Fair Trading Office in your
How do I get a job as a roof tiler?
Roof tilers undergo an apprenticeship to
become fully qualified in their trade, which generally
lasts 3 to 4 years, depending on state requirements. To
find out more about apprenticeships, visit www.australianapprenticeships.gov.au.
How do I best maintain my roof?
Maintaining tiles requires minimal effort.
However if your roof is old or you'd like to get it
checked after storm damage, we recommend contacting a
roof maintenance specialist who understands the correct
safety procedures to inspect your roof.
What is lichen?
Lichen or moss
can start to grow on tiles after long periods but does
not in any way indicate deterioration or affect the
performance of tiles. It can be easily removed with a
high pressure cleaner by a professional cleaning
Can you respray tiled roofs?
Depending on the material and method used
it is completely acceptable to spray concrete roof
tiles. However never spray terracotta as it would
interfere with the natural quality of the clay and over
time will peel away from the glazed surface.
How expensive is it to re-roof?
Bring your plans to one of our members and
they can provide an accurate cost estimate. There may be
surprisingly little difference between the cost of
respraying and installing new roof tiles.
Why is concrete not as colour-fast as
Concrete tiles are not glazed so
like all exterior building materials they are subject to
UV radiation and atmospheric pollutants. As a result
they will weather with age to a matt finish and will
lose some colour over time. Terracotta tiles are
kiln-fired with a vitreous coating that makes these
tiles resistant to harsh UV exposure and
What are the white streaks apparent on some
Sometimes the natural mineral salts
in concrete can migrate to the surface in the form of a
whitish grey discolouration called efflorescence. This
is not harmful, has no impact on the performance of the
tile and will weather away over time. This article
