Many people envision the “tin barn” look when they hear “metal roof”.

But using metal roofs has come a long way. Modern metal roofing includes a variety of styles and materials so that the roof looks stylish, while still maintaining durability, longevity, fire resistance and easy maintenance.

A variety of metals are used for modern metal roofs. These include the traditional aluminum and steel, as well as copper and a variety of alloys. Modern metal roofs can be formed into shapes that imitate Spanish tiles, wood shakes, and even slate. They can be given a variety of finishes including granulated stone topcoats to complete a realistic facsimile of almost any other material.

There are some negatives to a metal roof. One consideration is the cost, with a typical square running from $150 to $600. Another is the necessity of professional installation and maintenance, which also adds to the overall cost. Even with these negatives many believe the benefits make metal roofs worthwhile. A properly installed and maintained metal roof can realistically last as long as the house. That means, over a typical home's life time, the cost of a metal roof is lower compared to the cost of other roofing materials that might need replacement after 15 to 20 years.

Metal roofs are light, fifty to one hundred fifty pounds per square compared to seven hundred fifty pounds per square foot for tile or nine hundred pounds per square foot for concrete tile. Metal roofs don't require additional support when installed over existing roofs. Metal roofs withstand high winds, snow slides off them, and they resist mold, termites and other insects, and rotting associated with wood and other materials.

Pitch is another issue of concern with roofs. Other types of roofs require a steep pitch to ensure water flow so that the roof won't leak. The pitch for a metal roof can be more shallow, with a typical recommended minimum of 3-in-12, which is three inches of height for every horizontal foot. Consider the benefit of a less steep roof next time you have to climb onto it to clean the gutters, or retrieve a ball or Frisbee a child throws onto it.

Just as with other home projects that require a professional, the best way to find a metal roof contractor is through word of mouth. Talk to friends and neighbors, or look for metal roofs around the neighborhood and ask the home owners for the name of their contractor. The Internet is a good source to find pre-screened metal roofing contractors, as are architects who design homes with metal roofs. The National Roofing Contractors Association can also help. Call 1-800-USA-Roof for their advice.

You may not be ready for a cat on a hot tin roof. But if you want great roof for your home, consider that traditional wood and shingles are good, but metal may be better.
