Tin roofs over 1x4 slat boards is where the "noisy"
sounds of the rains pull through. Todays
construction standards have eliminated noise
Is a metal roof
damaged by hail?
Metal roofs are very tough and highly resistant to
hail damage... much more so than asphalt/fiberglass
shingles. In fact, many metal roofing products have
the highest impact resistance and hail rating
granted by the insurance commissions in the hail
belt regions of the U.S. Some insurance companies
even provide a reduced rate for metal roofs.
The Texas Experiment
State insurance authorities in Texas are
attacking the issue of hail damage by requiring
premium discounts for consumers who install
impact-resistant roofs. In January 1998,
Insurance Commissioner Elton Bomer ordered
homeowners insurance companies in the state to
discount premiums up to 46 percent in some areas
for policyholders who replace old roofs with
certified impact-resistant roofs. All insurers
subject to Texas rate regulations must offer the
How about resistance

Many styles have been tested to withstand hurricane
force winds; and wind warranties can be as high as
Is a metal roof fire

a Class "A" rating - the highest rating given.

a metal roof compare to other types of roofing?

Typically they weigh less than one-third the weight
of asphalt/fiberglass shingles; and are as much as
75% lighter than clay, concrete or slate.

Does the color fade?
Metal roofs are painted with high-performance
polymers that have exceptional weathering
properties. Over time you might notice a slight
change in color due to the settling of airborne
contamination, but occasional rain or washing the
roof with a garden hose (from the ground) will keep
the roof looking like new.

Will a metal roof make
my house hot?
Actually, a metal roof can save you money on your
a/c costs because it has a higher heat reflectivity
than other roofing products like asphalt/fiberglass
shingles, wood, tile, etc. During the summer it
makes buildings cooler by efficiently reflecting
away sunlight and reducing the amount of heat
transmitted into the building. Likewise, it makes
buildings warmer in the winter by reflecting inside
heat from the underside of the roof back into the
building. This good thermal reflectivity translates
into energy savings by reducing cooling costs in the
summer and heating costs in the winter.
What is Galvalume?
Galvalume is 55% Al-Zn (aluminum - zinc) coated
sheet steel that is ideally suited for most types of
roofing applications. An estimated 40 billion square
feet of Galvalume now covers buildings in all kinds
of climates and environments throughout the United
States, Canada and Mexico, as well as Europe, Asia
and Australia. Galvalume is an ideal material for
roofing because of its extraordinary outdoor
corrosion resistance and resulting long life. It is
extremely popular due to its versatility, ease of
use, aesthetics and long-term performance.
