1.Enviroment Friendly:The light weight nature of the tiles means
that less timber is used in the roof stucture as compared to
traditional roof tiles.Water harvested is safe for consumption.
2.Cost effective:It is so far the most economical roof age,for it
is waterproof,freezing tolerance,fireproof,aging-resistant,and
Up to 40% less timber is used on the roof structure and no
polythence or iron sheet underlay is required for roof pitches
between 5 and 60 degrees.
3.Maintenance Free:The tiles have up to 30 years warranty thus
4.Security:The tiles are nailed into the battens using serrated
nails thus providing burhlar proofing.
5.Structural Strength:No bending of tiles during installation
6.Heat and sound insulation:Compare to the galvanized
sheet,aluminum-sinc is more durable,heat-resisting,heatproof and
anti-corrosion.It is genenrally believed that steel roofing sheet
can guarantee 30 more years without being rusted or eroded in
FAQ’s About Stone-Coated Steel
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
for close to 60 years, but the product technology today bears
little resemblance to early practices due to advances in the
chemistry of coatings.
Will a Steel roof make my home hot?
No. A properly vented steel roof system moves air both between the
shingles and the underlying deck as well as moving air from vents
under the decking. Heated air is allowed to dissipate through the
ridgeline as cooler air is drawn through eave vents. Reduced energy
bills can result from airflow both under and over the decking.
Can you walk on a steel roof?
Yes. Some care must be exercised while walking on the roof, but
note that roofers walk all over the shingles during the
Is a steel roof noisy in the rain?
The roofing system is quiet. The combination of dead air space and
the stone coating minimize outside sounds. One rural couple
standing directly under a stone coated steel roof observed that
they could hear the rain striking a metal building about 50 feet
from where they were standing, but couldn’t hear any noise from the
stone/steel roof directly over their heads.
How wind resistant is a steel roof?
The roofing system has been proven to resist wind speeds in excess
Will a steel roof rust?
The steel substrate is protected from corrosion by layers of
metallic and polymer coatings. Metro utilizes an advanced metal
composite developed by BIEC International and introduced in 1973 as
aluminum-zinc coated steel. The composite improved earlier metallic
coatings by applying an aluminum-zinc alloy to the steel in a
continuous hot dip process. The aluminum creates an inert barrier
coat while enhancing the long-term performance of zinc and its
ability to protect breaks in the coating.
Galvalume coated steel has repeatedly been shown in industry
studies, conducted over the last 20 years, to outperform the
corrosion resistance of other coated metals. This is why the roof
system is referred to as "The final Roofing System", and is backed
up with a 30 year limited warranty.
Does the color fade?
Though sized more precisely, uses the same stone granules used by
asphalt shingle manufacturers for over 50 years, so history
demonstrates that fading is not a problem. 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.
How long does it take to install a steel roof?
Usually only a few days. The complexity of the building’s roof
space is the primary factor in determining the time required.
Complex roofs require more time than basic designs.
