What are the Tilcor Performance Guarantees?
Tilcor Steel Roof Tiles achieve the highest UL 2218 rating for hail impact resistance in the United States.
High Wind Resistance
Tilcor Steel Roof Tiles are engineered to withstand high wind
uplift forces and perform well in the “Very High Wind Zones” (VHWZ) of
coastal New Zealand.
Tilcor Steel Roof Tiles are a lightweight interlocking roof system, with uncompromising strength.
Tilcor Steel Roof Tiles are classified as a “Class A” Fire Rated, non combustible roofing material in the United States.
Tilcor Steel Roof Tiles are an interlocking roof system. The tiles are individually fixed and are less likely to fall through the ceiling during an earthquake.
Tilcor roof tiles are suitable for all marine environments and are backed by our warranty.
Protection from the Sun
Tilcor Roof Tiles incorporate “state of the art” acrylic coating
technology and have been tested in one of the most severe UV climates in
the world – New Zealand.
Engineered from high grade Zincalume coated steel, a Tilcor roof
is one of the most recyclable and sustainable building products in the
70 Years Roofing Experience
As a family business Tilcor’s growth has come from ownership, accountability, knowledge, research and hard work.
Weather Security Warranty
Full 25 year weatherproof warranty plus a diminishing pro-rata weatherproof warranty for the subsequent 25 years.
How long has Stone-Coated Steel roofing been around?
Stone-coated steel roofing occurred during World War II when tar and
sand were used to cover galvanized steel bunkers. After the war, the
practice was commercialized and the first roofs were produced. Stone
coated steel roofs have been protecting buildings since then, but the
product technology today bears little resemblance to early practices due
to advances in the chemistry of coatings.
Can you walk on a steel roof?
Yes. Though some care must be exercised while walking on the roof and
you should only place your foot on the flat section on the nose of the
tile,roofers walk all over the roof during the installation process.
Is a stone-coated steel roof noisy in the rain?
No. The modular tile system and the dead space between the steel
roofing panel and the underlay minimize exterior noise even in a
rainstorm. The stone-coating also reduces the noise of the rain when it
hits the tiles.
How will a Tilcor roof stand up to extreme weather?
A Tilcor roof can withstand decades of abuse from extreme weather
conditions including wind, heat, humidity and rain. Tilcor has many
international test reports and actual field results confirming their
products are earthquake, fire and freeze/thaw resistant and can
withstand hurricane-forced winds of up to 193kph. With a minimal amount
of periodic maintenance a Tilcor roof will provide years of lasting
How do the granules stay bonded to the steel?
An acrylic primer is applied to the Zincalume coated steel substrate
by the steel mill. Graded, non-oiled stone granules are then embedded in
a thick UV resistant water base acrylic polymer. A final layer of
acrylic over-glaze is applied on top of the stone before the tiles are
cured in an oven at a temperature of 120 degrees.
Will a steel roof rust?
The ZINCALUME coated steel has been formulated to give a
significantly longer service life than a galvanized coating. The
ZINCALUME steel coating combines the corrosive protection of aluminium
with the sacrificial protection of zinc, giving the advantages of both
metals. The resulting alloy coating enhances corrosion resistance,
making it ideal for such applications as roofing. This is why the Tilcor roof system is referred to as “The final Roofing System”, and
is backed up with a 50 year limited warranty.
Does the color fade?
The history of Tilcor’s products demonstrates that fading is not a
problem. Tilcor uses either naturally colored or ceramic coated
stone granules on their tiles. The natural stone cannot fade and the
ceramic coated stone is manufactured with the highest quality pigments
and fired at temperatures above 700 deg Celsius. Over time, a slight
change in color may occur due to settling of airborne contaminants.
However periodic rain or washing the roof with a garden hose will keep
the roof looking new.
I’m concerned about the environment. Is the roofing material recyclable?
Yes, over sixty percent of most metal roofing materials are
recyclable. Other roofing products are made of non-recyclable material.
Is a steel roof fire safe?
Steel roofing is classified as a non-combustible roofing material
(Class A). In new construction and in many re-roofing applications the
metal roofing system is a Class A non-combustible roof assembly. That
means it is the most resistant to fire.
What about energy efficiency?
Metal roofs have a high reflectivity, which contributes to the overall energy efficiency of your home.
Can I drink water from my roof?
Yes, rainwater collected from Tilcor roofs is safe to consume.
After your new roof has been installed you need to wait for two good
rainfalls before beginning collection.
What is the installed weight of a steel roof in comparison to other products?
Tilcor Steel Panel
Standard (3-Tab) Asphalt Shingles
Clay / Concrete Tiles*
*Note that the weights for clay and concrete products are for dry
weights and that the weight of these products increases when wet.
Are steel roofs more susceptible to lightning strikes?
Steel roofing is no more susceptible to lightning than other roofing
materials. It has been demonstrated that lightning strikes most
frequently the highest points of terrain. Where concerns exist,
lightning rods can be installed on roofs that are the highest point of
Does Tilcor offer a warranty?
Yes, when installed to the required standards and with the required
maintenance Tilcor roofs can carry a warranty of up to 50 years. A
five year installation warranty is also offered by the installers.
