Metal Roofing
Types Of Metal Roofing
Stone Coated
Stone coated metal
roofing panels are made from zinc or aluminum coated steel with
acrylic chip. Stone coated steel is a premium roofing product,
meaning it has superior durability and longevity to other
roofing products.
Corrugated Iron
Corrugated iron is
used more commercially than for residential roofs. There are
many different types of metal roofing. Corrugated iron is
composed of sheets of hot-dip galvanized steel that is
"cold-rolled" to create a corrugated pattern. Corrugated iron is
lightweight and easy to transport which makes it popular in
industrial and agricultural industries.
Standing Seam
Metal standing seam
panels, also a sheet form, has a seam on one end and a lock at
the alternative end by a process called roll-forming. The lock
is installed with clips. Dutch seam, a popular form of standing
seam is when the seam snaps together. Metal standing seam panels
are very water-resistant, however, they do usually require
custom cutting.
Shingle
Roof shingles
consist of individual overlapping panels or tiles. These tiles
are normally flat rectangular shapes that are laid in rows
without the side edges overlapping, a single layer is used to
ensure a water-resistant result. Metal shingles look like
asphalt or clay tiles by pressing metal into molds to create the
shingle panels. Metal shingles can come in a variety of colors,
textures and sizes.
Copper
Copper, because of
its expensive price, is usually used only for entryways or roof
ridge caps. Copper does however, have a 200 year life span.
Aluminum
Aluminum is one of
the longest lasting metals, however, like copper it is very
costly. Aluminum roofs also offers some other great benefits
including being lightweight, corrosion-resistant and energy
savings of its reflectivity.
Metal Roofing Benefits
Steel Roofs
have several benefits, among them cost effectiveness, rust
resistance, improved roof longevity, and improved durability to
severe weather such as wind, rain, hail, earthquakes, snow and
fire. Additionally, stone coated roofs have several more
benefits.
Rain & Wind – When wind driven
rain blows sideways at 100 miles per hour, a lot of damage can
be caused by even the smallest drip. Steel roofing products
are designed to overlap side to side and top & bottom in a
stair-step fashion, fastened to a batten system, and secured to
your home's framing members in such a way that even the most
ferocious rain has no chance of penetrating the roof. Wind
doesn't have a chance to catch the bottom edge of the panels
because they are fastened to your home in such a way that
virtually eliminates any blow-off.
Hail – You've seen the damage on the news when hail
wreaks havoc on businesses, cars, and homes. Some insurance
companies frown on replacing roofing material with the same roof
that was just ruined. Ask your insurance company what they will
do if you replace your roof with a our roofing products
come with a 2.5 inch hail warranty and have a UL 2218 Class 4
Rating.
Earthquake – When the earth shakes
in many parts of the world, heavy weight roofs come tumbling
down, crushing practically everything below them. Wouldn't you
rather feel secure in the knowledge that the roof above you is
one of the lightest on the market today? These roofing
products, at about 1 pound per square foot, weigh less than
30 year dimensional shingles and between 5 and 8 times less than
concrete tiles. Steel roofs are fastened to the framing members
of your home, thereby adding shear strength to the entire
structure, helping hold it together.
Snow – Heavy snow loads can cause destruction by
crushing roofing materials, breaking off the bottom roof edges,
or worse yet, sliding down the slick roofing, endangering all
those beneath. Steel roofing products are engineered in
such a way that even the heavy, wet snows of Lake Tahoe's
"Sierra Cement" won't damage them. Even with all that weight,
the harmful effects of "freeze-thaw," and the intense sun of
that clear mountain air, steel roofs prevail!
Fire – Obviously, steel doesn't burn! After many house
fires we see on the news, often we hear the interviewed firemen
say "the reason we lost this house was because the roof was made
of wood." Steel roofs eliminate this hazard and are class
"A" fire rated... the best rating you can get!
Cost Effective - The initial
cost of installing a steel roof may be more than with other
roofing materials. However, the money a homeowner can save
overall is significant, because a steel roof will be the last
roof you ever buy. A steel roof adds to your home’s beauty and
to its resale value. In addition, insurance companies in many
states will lower your homeowner’s insurance premiums by between
5% and 36% for the proven protection of steel roofs. Finally
steel roofs reduce the Energy consumption by up to 30% with the
Energy Star program, which also allows for a Tax Credit each
year. In the case of a new home, a steel roof will reduce the
Dead Load of the truss package, therefore reducing the cost. In
the final analysis a steel roof is the best investment you can
make in either a new home or when re-roofing an existing home!
Rust Resistance – Steel
roofs are coated with zincalume, a proprietary coating that
offers significant rust protection. Thereafter, they are either
coated with premium quality Kynar paint, or with a stone (or
granular) coating, to enhance the look and longevity of your
roof.
Longevity - The average life of a
non-steel roof is approximately 12 years. For example, asphalt,
or “composition” shingles can require re-roofing every 10 to 20
years or sooner! Compare that with a steel roof that includes a
warranty that is good for 50 years!
