This document discusses how metal roofing can help protect homes and buildings from extreme weather in different parts of the United States. It provides examples of areas that experience intense heat, cold, snow, winds and other weather where metal roofing is beneficial. Metal roofing can withstand high winds up to 140 mph and resist snow and ice better than other materials. It is also very durable and can last 40-60 years or more before needing replacement. The document then describes a project where a historic home in Washington was renovated and given a new metal roof made to look like wood shakes, providing protection from the heavy rain and winds common to the Pacific Northwest region.

Anything can happen in
the United States weather-
wise. Here are some specific
examples of areas where
metal roofing can help.
Weather: How Metal Roofing
Can Help
By Sharon Glorioso
E
xtreme weather is rampant across
the United States. From Arizona’s
intense heat to Minnesota’s frigid
winters, not to mention Colorado’s deep
heavy snow, metal roofing can be the
perfect answer to protect your home or
commercial building from a wide variety
of inclement weather.
According to Semper Fi Roofing and
Stone Flooring, based in Waukesha,
Wisconsin, extreme weather is one
of many reasons why their clients are
choosing to go with metal.
“There are a lot of reasons for home-
owners to select a metal roof over tra-
ditional asphalt roofs,” says Ryan Boss,
production manager with Semper Fi
Roofing.
Just in August, Wisconsin hit over 90
degrees Fahrenheit and this winter, it
won’t be surprising if in February it is
-40 degrees below Fahrenheit. It is areas
like this where clients are choosing to use
metal to get the most out of their roofs.
According to the Metal Roofing
Alliance (MRA), a metal roof can with-
stand decades of abuse from extreme
weather like high winds, heavy snow,
hailstorms and even wildfires, such as
in California. “Metal roofing has a 140-
mph wind rating, meaning it can with-
stand wind gusts up to 140 miles per
hour,” says MRA officials.
Under high wind conditions, says
architect Jim Mitchell, “Metal roofing
systems have wind resistance and uplift
resistance that is above the new building
code requirement. That gives us a sense
of relief in that we can use the best mate-
rial to meet those criteria.”
In locations that see heavy snow, metal
roofing has been the choice of home-
owners for years, according to the MRA.
It sheds snow fast, which protects the
structural integrity of the roof. And it
can eliminate ice damming at the eaves,
so water can’t back up and collect under
the roof then leak into your home.
Does Not Decompose; Lasts
So Much Longer
You can expect a metal roof to last at
least two to three times longer than a
non-metal roof. In general terms, count
on a metal roof lasting 40 to 60 years and
beyond.
To put it in context, the average life
span of an asphalt roof is 12 to 20 years.
That lifespan can be shorter depending
on the pitch of your roof and the climate
in your area. Made of oil impregnated
paper or fiberglass, asphalt begins to
deteriorate as soon as you expose it to
normal weather. A metal roof, however,
will never decompose.
Other roofing materials like wood
shingle, shake and tile have varying
degrees of weather-related problems
that lead to breakdown. Wood shingle
and shake roofs often need replacement
before 20 years. Concrete tile roofs can
crack and warp in the freeze/thaw cycle
of more northern climates.
All of the above roofing materials are
well-outlasted by metal roofing, which
retains its good looks and durability
decade after decade after decade.
In the following pages, several project-
specific examples highlight how metal
roofing is out-performing any area of
extreme weather.

Architects Use Metal Shake Roofing to Renovate
Historically Significant Seattle-Area Home
By Dale Walton
Renovating a historic home, especially
one designed by a famous architect, is
never an easy task. The value of preserv-
ing the original architect’s design must be
weighed against that design’s practicality
and functionality in today’s world, as well
as the preferences of today’s homeowners
and the weather where it is located.
Lochwood-Lozier Custom Homes
& Remodeling, LLC, of Redmond,
Washington, recently faced this chal-
lenge when planning the renovation of
a Mid-Century Modern home in Clyde
Hill, Washington, designed by renowned
Seattle architect Ralph Anderson.
Anderson was known for crafting
designs that blended with the landscape
of the Pacific Northwest, with broad
windows, protective rooflines, exposed
framing and an emphasis on vertical-
ity as his signature tools. The home sits
among picturesque surroundings in
Clyde Hill, perched above a nearby golf
course. While preserving Anderson’s his-
toric home design was certainly impor-
tant, gently updating the home was
equally essential. In its renovation design,
the Lochwood-Lozier team members
presented its interpretation of how they
believed Anderson would have designed
the home for today’s homeowner.
“We wanted to be thoughtful to the
original architecture, but we also needed
to make the home a more modern, func-
tional living space for a contemporary
family,” said Mike Weihe, project man-
ager for Lochwood-Lozier.
One of the most prominent updates
the home needed was a reroof. After
more than 50 years, the original wood
shake roof’s beauty and weatherability
had finally begun to fade.
“Due to the high quality of lumber still
available for wood shakes in the 1960s,
the shakes were actually not in as bad of
condition as you would have expected,”
Weihe said. “But, the roof had reached
the end of its functional life. And since
you can see a large portion of the roofli-
ne when you drive up to the house, we
needed a new roof that really popped.”
To stay true to the architectural style
of the home, Lochwood-Lozier wanted
to retain the shake-style look in the new
roof; however, they wanted to achieve
this look with an alternative material,
as the quality of lumber used for wood
shakes today is not as good as it used to
be. Plus, choosing a wood alternative over
the real thing would reduce the project’s
environmental footprint. In addition
to being environmentally friendly and
having strong curb appeal, the new roof
would need to be rugged and durable for
long-lasting protection from the frequent
rain and wind of the Pacific Northwest.
The project also required the use of new,
innovative and sustainable building
products wherever possible.
Presidio Shake Used For High
Wind, Hail Resistance
Weihe contacted CertainTeed about a
new metal roofing product line that the
manufacturer was introducing called
Presidio. The product’s deep-drawn steel
panels are shaped and distress-painted
to replicate the look of classic roofing
materials, such as wood shake, slate
and tile, but offer higher wind and hail
resistance and solar reflectance prop-
erties. Available in shake, slate and tile
profiles and a variety of colors, many of
the Presidio colors have been rated by the
Cool Roof Rating Council to have solar
reflectance values between .26 and .34,
and unlike wood, can achieve a Class
A fire rating. And, given that they are a
metal product, the product is recyclable
at the end of its useful life.
After considering its many sustainable
and aesthetic attributes, including a life-
time limited warranty, Lochwood-Lozier
found the product to be a great fit for the
roof, and specified Presidio Shake in the
color Ash.

Good Defense Against
Damaging Weather
“We have plenty of wind and rain in
our region, which causes a lot of debris
to fall from trees, and we knew metal
roofing would provide a good defense,”
Weihe said. “I like how Presidio Shake
offered that kind of protection, but with
the authentic profile and texture that
would allow us to retain the look of the
original roof. I also liked the fact that the
product would make a smaller environ-
mental footprint than wood shakes.”
Pinnacle Roofing Installs
Beautiful New Metal Roof
Lochwood-Lozier hired Pinnacle
Roofing Professionals, LLC, of
Lynnwood, Washington, a contractor
with ample experience installing stand-
ing seam metal roofing, for the reroof.
Since this was the contractor’s first
experience working with the new metal
shake product, CertainTeed representa-
tives trained the crew in proper installa-
tion. With this assistance, the Pinnacle
Roofing Professionals crew caught on
rather quickly and continued on toward
a smooth installation.
“Roofers get set in their ways and don’t
like change, so there’s always a learning

curve when we’re introduced to a new
style of roofing,” said Lenny Schwartz,
owner of Pinnacle Roofing Professionals.
“We put together a crew of our more
open-minded guys, though, and our
CertainTeed reps were always available
for support whenever we had questions.”
Before the roofing crew began,
Lochwood-Lozier’s crew removed the
original shakes and made all necessary
repairs to the framing and plywood roof
deck. The design was a common gabled
roof with a hip over the garage and an
average pitch of 5-1/2/12. Using a crew
of five, Pinnacle Roofing Professionals
first applied MetaLayment self-adhering
waterproofing underlayment along the
eaves and valleys and then nailed down a
layer of DiamondDeck high-performance
synthetic roofing underlayment as a base
for the shakes, per manufacturer guide-
lines. The crew then installed 50 squares
of Presidio Shake, along with hip, ridge
and flashing accessories. The new prod-
uct is 16 panels and 96 pounds per square.
Very Few Installation
Obstacles; Finished Early
Pinnacle Roofing Professionals
encountered very few obstacles and
finished in 12 days—far less than the
month-long time frame planned initially,
and their work received excellent feed-
back from Lochwood-Lozier. “It’s a beau-
tiful roof that definitely lends itself to the
Mid-Century Modern style,” Weihe said.
“This roof looks like it belongs on this
house, and I like that.”
Homeowners Michele and Bob
Conrad were also pleased with the roof’s
appearance, as well as the weatherability
it offers.
“We wanted a shake-style roof, but
with the modern technology to make
it last longer,” Michele Conrad said.
“Nothing can hinder our roof, now that
we have metal shakes. And to top it all off,
it looks spectacular.”
In addition to winning the praise of
its customer, Lochwood-Lozier went on
to win the 2015 Northwest Idea House
award from Seattle’s 425 Magazine for
innovative, functional home design.
Pinnacle Roofing Professionals has
gone on to complete more installations
with the product since the Clyde Hill
project and now lists Presidio as their
preferred replacement for wood shake
roofing and have gone on to complete
more installations with the product since
the Bellevue project.
According to Schwartz, the metal roof-
ing products are increasingly attracting
the attention of HOAs in his company’s
service area, which he is anticipating will
lead to even more happy homeowners.
