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.
