WHY METAL?
Q. What are the advantages of a metal
roof over other types of roofs?
A. Pre-finished metal roofing is offered in a
large selection of colors with long life
coatings that guard
against the growth of moss, mildew, or fungus.
Metal panels are lightweight but strong enough
to withstand all types of weather. Finally, a
metal roof will last longer than other roofs, will conserve
more energy and you will have virtually no
maintenance.
Q. Can I install metal panels directly
over my old, worn-out shingles?
A. Metal weighs about 1/3 of what shingles
weigh, which will allow panels to be applied
without
removing your existing roof. This eliminates the
cost and problems of disposing of the old
shingles.
The best way to do this is to attach 1"x4" or
2"x4" lathing at 24" o/c parallel to the eave
and ridge.
Q. How do I attach metal panels?
A. You may use either screws or nails-both color
matched to the color of your roof. Screw
fasteners are
preferred over nails for superior pullout
resistance and weather tightness. Screw
fasteners are
designed to go into the flat part of the panel.
Nails MUST go in the high rib of the panel.
Fasteners,
typically spaced 24" o/c.
Q. Can I add insulation under the metal
panels?
A. Yes. Among the types of insulation that can
be used are fan-fold foam insulation or
foil-faced plastic
bubble insulation.
Q. Is metal roofing noisy when it rains?
A. No more noisier than what you listen to now.
The metal roof panels are installed over felt
paper and
plywood on the outside, with a layer of
sound-deadening insulation and your drywall
ceiling on the
inside. These materials help reduce the noise
level of rain.
Q. How long will a metal roof last?
A. It will probably be the last roof you will
have to put on your home, shed, barn or
business. Metal roofs
life expectancies can easily exceed 30 years.
Corrosion resistant substrates and long-life
finishes ensures
long-term performance, minimal maintenance and
life-cycle cost savings.
Q. Will a metal roof make my house or
building more susceptible to a lightning strike?
A. No. A metal roof will not make a building
more susceptible to a lightning strike.
Lightning will tend to
strike the highest object in a given area,
regardless of what that object is made of. A
metal roof can
actually be beneficial in the event of a
lightning strike due to being a non-combustible
material.
Q. Is installing a metal roof very
difficult and does it take a long time?
A. Most metal roofing materials come in
multi-shingle sections or in sheets. An
accomplished contractor
can install these quickly. If your roof is
stripped off and a storm is on the way,
shortening the process
by a day or two may prove to be a critical
advantage.
Q. Are metal roofs very resistant to
fire?
A. Because metal roofs are noncombustible,
they're given a Class A fire rating(the most
resistant). Part of
a roof's classification depends on materials
beneath the surface that could ignite in intense
heat, so
some metal roofs applied over an old combustible
roof--such as wood shingles--may be rated lower.
Q. What does the pitch of my roof need
to be in order to have a metal roof installed?
A. Most metal roofing material can be installed
on gently pitched roofs without danger of
leaking.
Typical minimum roof pitch is 3:12 (the roof
rises three inches for each horizontal foot).
Q.
Will metal affect television reception? A. Yes, metal roofing may affect the
antenna signal if it is too close to the
metal roof outside.
The reason is very
plain and simple that metals do not
allow the radio waves to pass through
them that easily.
Getting a pole to put
the antenna on, placing it at least 3 feet above the metal top roof would work
great for a majority of people.
Keep the
golden rule in mind that the higher the
antenna is installed the better the
reception.
Another way to get good
signals is to buy an amplifier but if
you increase the height of the
antenna
for installation then it may work and
catch good signal without needing any
supportive device.
