Metal roofing

Many people envision the “tin barn” look when they hear “metal roof”. But metal roofing 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 many other materials.

There are some negatives to a metal roof. One consideration is the cost, with a typical square running from $150 to $600. Another is that metal roofs usually require professional installation and maintenance, which also adds to the overall cost. Despite these negatives many people feel that metal roofs have benefits that make them worthwhile. A properly installed and maintained metal roof can realistically last as long as the house. That means, over the typical life expectancy of a home, the cost of a metal roof is low compared to the cost of other types of roofs that might require 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 resist high winds, snow slides off them, and they are resistant to mildew, insects and rot.

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 benefits of a flatter roof next time you have to climb onto it to clean the gutters, or retrieve a ball or Frisbee thrown there by a child.

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 for pre-screened metal roofing contractors, as are architects who design homes with metal roofs. Also consider the National Roofing Contractors Association. 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, remember that traditional wood and shingles are good, but metal is better.
