How to Choose a Metal Roof

February 6, 2007

If you are considering a metal roof, you need to learn a few things about it before making a final decision.  Metal roofing is an excellent choice in many situations. The many choices of style, shape and color just might surprise you with their very modern look.  If you are familiar with the range of choices it is much easier to select the one that is just right for your home.

Let's start with the metal in a metal roof.  Most metal roofing is made of steel, but it is also available in stainless steel, aluminum, copper, and several metal alloys.  Stainless steel, copper, and metal alloys are the most expensive choices but they also tend to be the most natural looking, durable, and resistant to denting and scratching.  Think about your budget as well as the look and style you want when determining what kind of metal to choose.

It is also possible to choose one type of metal for the majority of the roof and then select another metal (such as copper) for decorative edging or highlights.  Another consideration is the way metal roofing is manufactured.  You can get large sheet metal materials, large sheets of shingle style materials, or individual shingles that must be individually placed and secured.  Each of these types will create a slight different look and feel, with sheet metal and sheets of shingles being the quickest and easiest to install.

Just as important as the metal roofing itself is the underlayment for the roof.  Many metal roofing systems can be installed over the top of existing shingles, while others work best when the roof is stripped down and fresh surface is created.  Whenever possible, opt for a smooth surface that includes sound proofing and insulating qualities.  This will increase the life of your roof, make your home more energy efficient, and cut down significantly on the noise created by rain or hail falling on the roof.  Regardless of the style of underlayment and roofing you choose, be sure to use the correct fastening system for installation.  Metal roofing will expand and contract with heat and cold, which can cause regular fasteners to come loose and even fall out.  Choose the right fasteners for your metal roof and you will be very happy with the results.
