When people think of metal roofing they think of the corrugated “tin barn” look.

But using metal roofs has come a long way. Today metal roofing includes a variety of styles and materials so that the roof has style and visual appeal, while retaining durability, longevity, fire resistance and easy maintenance.

Metal roofs are made from a variety of metals. Some of these are 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 such as granulated stone topcoats to complete a realistic imitation of almost any other material.

It isn't all peaches and cream, because metal roofs have some negatives. A typical square can cost between $150 and $600, so that's one issue for consideration. Another is the necessity of professional installation and maintenance, again adding to the overall cost of a metal roof. But even with these negatives many feel 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 expected life, the cost of a metal roof is low compared to the cost of other roofing materials that might require replacement after 15 to 20 years.

Metal roofs are lightweight, fifty to one hundred fifty pounds per square compared to 750 pounds per square foot for tile or 900 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 are resistant to mildew, insects and rot.

Pitch is another important factor 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 being 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. Ask neighbors or friends, or look for metal roofs around the neighborhood and ask the home owners who installed them. 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. Their number is 1-800-USA-ROOF.

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