There are two facts that cannot
be disputed relative to the usage of metal for the roof of your home or
business. The first is that The Metal
Roofing Association (MRA) has reported that non-metal roofs last 17 years on
average, but metal roofs can last a lifetime. Though higher in initial costs,
they can boost homes’ resale value and cut homeowners’ insurance premiums in
some states by up to 35 percent. The
second is The Metal Construction Association (MCA) has produced a study that
found that certain metal roof systems can last at least 60 years, meaning they
do not require replacement during a commercial building’s service life.
What do we know about metal
roofs? Metal roofing systems do not rot,
warp, crack or break. They are also superior to conventional roofing systems in
standing up to extreme weather with great finish warranties and guarantees to
warranty in high winds-an important factor of roofing systems in
Micronesia. Metal roofs last two to
three times longer than ordinary roofs, meaning they can last 40 to 60 years or
longer, according to both the MRA and MCA.
The MCA holds that the expected service life of an unpainted 55%
Al-Zn coated steel (known by many trade names throughout the world, principally
GALVALUME® and Zincalume® in the United States) standing seam roof constructed
today in a wide range of environments using best practices can be expected to
be in excess of 60 years, a value that equals the assumed building service life
as described in the US Green Building Council’s Leadership in Energy and
Environmental Design building rating program, Version 4. The study also
confirmed that these types of metal roofs resist corrosion even in
"weak" spots, such as sheared edges and panel profile bends.
Inspections showed an absence of significant red rust after up to 35 years,
indicating exceptional corrosion resistance in areas susceptible to exhibiting
the first signs of corrosion.
While we would be the first to ask you to make the switch,
it is clear that one thing needs to be done to protect these investments over
time-maintenance. All roof systems
require a regular maintenance program to annually clean off debris and to
inspect the condition of the roof in order to achieve the kind of service lives
reported in this blog post. While steel standing seam roof systems were
projected to last up to 60 years, components such as fasteners may need to be
replaced during the roof life, but this represents significantly less than 20%
of a total roof replacement cost.
